What Is Plant Tissue Culture

Plant tissue culture – Wikipedia

Plant tissue culture is a set of procedures that are used to retain or develop plant cells, tissues, or organs under sterile circumstances on a nutrient culture medium that has a specified composition in order to produce a specific product. Micropropagation, often known as plant cloning, is a technique that is frequently used to make clones of plants. The use of different methods in plant tissue culture may provide significant benefits over traditional methods of propagation, such as the following:

  • It is the practice of creating precise replicas of plants that produce exceptionally nice flowers, fruits, or have other desired characteristics. In order to grow mature plants as rapidly as possible
  • Generation of large numbers of plants in the lack of seeds or the presence of pollinators essential for the production of seeds
  • Genetically engineered plant cells are used in the regeneration of whole plants. The production of plants in sterile containers that allows them to be moved with a greatly reduced risk of transmitting diseases, pests, and pathogens
  • The production of plants in sterile containers that allows them to be moved with a greatly reduced risk of transmitting diseases, pests, and pathogens
  • Developing plants from seeds that would normally have very poor possibilities of germination and growing, such as orchids and Nepenthes
  • To rid certain plants of viral and other diseases and to rapidly proliferate these plants for use in horticulture and agriculture as ‘cleaned stock.’

Using plant tissue culture, researchers take use of the fact that a large number of plant cells have the potential to regenerate a whole plant (Cellular totipotency). Single cells, plant cells without cell walls (protoplasts), sections of leaves, stems, or roots can all be used to grow a new plant on culture media if the medium has the necessary nutrients and plant hormones (see below).

Techniques used for plant tissue culture in vitro

The preparation of plant tissue for tissue culture is carried out under aseptic circumstances in an alaminar flow cabinet with HEPAfiltered air supplied by a dehumidifier. Following that, the tissue is cultivated in sterile containers, such as Petri dishes or flasks, in a growth environment with temperature and light intensity that are carefully regulated. The surfaces of living plant materials from the environment are naturally contaminated with microorganisms, so their surfaces are sterilized in chemical solutions (typically containing alcohol and sodium or calcium hypochlorite) before suitable samples (known as explants) can be collected and studied.

  1. Solid and liquid media are mostly constituted of inorganic salts, with a little amount of organic minerals, vitamins, and plant hormones thrown in for good measure.
  2. Potato explants were cultured in vitro to produce tissue.
  3. For example, an excess ofauxinwill frequently result in the proliferation of roots, but an excess ofcytokininwill likely result in the production of shoots.
  4. In order to allow for development or to modify the morphology of the culture, portions of the culture are routinely cut off and subcultured onto fresh medium as the culture matures.

As branches form from a culture, they may be cut off and rooted with auxin to generate plantlets, which can then be transplanted to potting soil for further growth in the greenhouse as regular plants after they have reached maturity.

Regeneration pathways

Plant tissue cultures are being cultivated at the National Center for Genetic Resources Preservation, which is operated by the United States Department of Agriculture. There are a variety of theories for the unique variances in the regeneration capability of different organs and explants that exist. The variations in cell cycle stage, the availability of endogenous growth regulators or the capacity to transfer them, and the metabolic capacities of the cells are the most critical elements to consider.

These tissues have rapid cell division and either concentrate or synthesize the necessary growth-regulating chemicals, including as auxins and cytokinins, that are essential for proper development.

As a result, tissue culture regeneration can become challenging, especially when several regeneration processes for various genotypes within the same species must be devised.

In most cases, the propagation of shoots or nodal segments is performed in four stages for the mass production of plantlets through in vitro vitrovegetative multiplication, but organogenesis is a common method of micropropagation that involves the tissue regeneration of adventitious organs or axillary buds, either directly or indirectly from the explants, and is a common method of micropropagation.

Non-zygotic embryogenesis is a significant developmental process that is extremely analogous to that of zygotic embryos.

Because non-zygotic embryos are formed from a single cell, they are favoured in a variety of regeneration systems, including micropropagation, ploidy modification, gene transfer, and synthetic seed synthesis, among others.

Choice of explant

An explant is a piece of tissue taken from a plant that will be used in a culture. Single undifferentiated cells, as well as many different types of mature cells, can be used to create explants. Explants can be taken from many different parts of a plant, including portions of shoots, leaves, stems, flowers, roots, single undifferentiated cells, and many different types of mature cells, as long as they contain living cytoplasm and nuclei and are capable of de-differentiating and resuming cell division.

This, however, is not true for all cells or all plants in the same way.

The choice of explant material also impacts whether the plantlets produced during tissue culture are haploid or diploid in nature.

When compared to the other two methods, the first method, which involves the use of meristems and the induction of multiple shoots, is the preferred method for the micropropagation industry because the risks of somaclonal variation (genetic variation induced in tissue culture) are reduced to an absolute minimum.

  1. Some explants, such as the root tip, are difficult to separate and are contaminated with soil microorganisms, which can cause problems throughout the tissue culture process if not handled properly.
  2. Soil particles that have been entangled with roots are difficult to remove without causing damage to the roots, which then permits a microbial attack to take place.
  3. Some cultured tissues develop at a snail’s pace, and this is a problem.
  4. Necrosis can cause the degradation of cultured tissues.
  5. As a result, it can be controlled by cultivating particularly sensitive cultivars (or tissues).
  6. Although they are more readily removed from the explant by gentle washing, the remaining bacteria are typically eliminated by surface sterilization, which is a common practice.
  7. Visual evaluation of the explant will frequently reveal such associations as a mosaic, de-colorization, or localized necrosis on the surface of the explant.
  8. Considering that seeds have a hard surface that makes them less permeable to the penetration of severe surface sterilizing chemicals, such as hypochlorite, the allowable sterilization conditions employed for seeds can be far more strict than those used for vegetative tissues.

If the original mother plant that was used to create the first explants is vulnerable to a disease or a certain environmental situation, the entire crop will be susceptible to the same ailment. Positive characteristics, on the other hand, would remain inside the limits of the line.

Applications of plant tissue culture

Plant tissue culture is widely utilized in the plant sciences, forestry, and horticulture, among other fields. Among the applications are:

  • This refers to the commercial manufacture of plants for use as potting, landscaping and florist subjects, which employs meristem and shoot culture to generate vast numbers of identical individuals. Toconservare or endangered plant species are two words that come to mind. Instead of screening cells for desirable characteristics, a plant breeder may utilize tissue culture to screen cells for advantageous characteristics, such as herbicide resistance or tolerance. Plant cells are grown on a large scale in liquid culture in bioreactors for the synthesis of important substances such as plant-derived secondary metabolites and recombinant proteins that are utilized as biopharmaceuticals.
  • By fusing protoplasts and regenerating the novel hybrid, it is possible to bridge species that are distantly related. To swiftly investigate the molecular underpinnings of physiological, metabolic, and reproductive functions in plants, for example, by in vitro selection for stress resistant varieties. Cross-pollination between distantly related species followed by tissue culture of the resultant embryo that would otherwise perish (Embryo Rescue)
  • For the purpose of chromosomal doubling and the production of polyploidy, such as doubled haploids, tetraploids, and other kinds of polyploidy, This is often accomplished by the use of antimitotic medicines such as colchicine or oryzalin. Transformation of a tissue followed by either short-term testing of genetic constructs or regeneration of transgenic plants It is possible to grow clean plant material from virused stock using procedures such as meristem tip culture, which may be used to a variety of plant species including sugarcane, potatoes, and many types of soft fruit. It is possible to generate identical sterile hybrid species by breeding them together
  • Somatic embryogenesis is used to produce fake seeds on a large scale.

A variety of independent laboratories provide specialized plant propagation services, despite the fact that several growers and nurseries have their own labs for the method of tissue culture. Many commercial tissue culture laboratories are listed on the Plant Tissue Culture Information Exchange website. Because plant tissue culture is a time-consuming and labor-intensive procedure, it would be crucial to consider this when evaluating which plants would be financially feasible to produce in a laboratory setting.

Tissue Culture Technology

Every plant, just like every individual is different and one-of-a-kind, is also unique. Some have characteristics like as improved color, yield, or insect resistance. Scientists have been searching for technologies that would allow them to create perfect replicas of these exceptional individuals for many years. Plants normally reproduce by generating seeds, which is a process known as sexual reproduction. In other words, pollen from the stamens of the plants fertilizes the egg cells in the flowers of the plants.

DNA from both parents is mixed in unforeseen and novel ways during sexual reproduction, resulting in the creation of distinct plants.

Several of us believe that all plants are propagated from seeds.

And scientists are now accomplishing this with the use of a technique known as “tissue culture.”

What is Tissue Culture?

It is the growing of plant cells, tissues, or organs on specially prepared nutritional medium that is referred to as tissue culture (TC). Under the correct circumstances, it is possible to regenerate a whole plant from a single cell. Plant tissue culture has been around for more than 30 years and is a relatively simple procedure. When it comes to the development of disease-free, high-quality planting material as well as the quick production of large numbers of homogeneous plants, tissue culture is considered a critical technique for developing nations.

  • It is possible to create thousands of duplicates of a plant in a short period of time in this manner.
  • They also have a shorter and more consistent production cycle, and generate larger yields.
  • Its implementation needs simply a sterile workplace, nursery, and greenhouse, as well as highly trained personnel.
  • Oil palm, plantain, pine, banana, date, eggplant, jojoba, pineapple, rubber tree, cassava, yam, sweet potato, and tomato are among the plants that have been grown in tissue culture and are important to developing countries.

Other plants that have been grown in tissue culture include yam, sweet potato, and tomato. This application of traditional biotechnology is the most widely used kind of traditional biotechnology in Africa.

Uses of TC technology in Asia

  • In order to meet the demands of orchid species and hybrids that are known to thrive in Southeast Asia, tissueculture has been modified throughout time. Thailand, Singapore, and Malaysia have all found that the ornamental and cut flower trade is a significant source of foreign exchange and additional income for small growers. In Thailand, tissue culture is used to reproduce slow-growing and environment-sensitive orchids, which are difficult to grow in their natural environment. With a production capacity of 50 million plantlets per year, Thailand is the leader in tissue culture in Southeast Asia. For the most part, these are orchids, which have allowed the nation to become the world’s leading exporter of entire and cutorchids. Micropagation by shoot culture technology has been created for the bulk multiplication of bananas. Banana bunchy top virus (BBTV) and banana bract mosaic virus (BBrMV) are two viral infections that are often propagated by propagative materials in the Philippines, and this is employed as a control strategy.

Benefits of TC technology for small-scale banana producersin Kenya(Source: ISAAA)

In Kenya, as in many parts of thetropical and subtropical developing world, banana is a highly important foodcrop. In the last 20 years, however, there was a rapid decline in bananaproduction due to widespread soil degradation and the infestation of bananaorchards with pests and diseases. These problems were further aggravated by thecommon practice of propagating new banana plants using infected suckers. Thesituation was threatening food security, employment and incomes inbanana-producing areas.

With proper management and fieldhygiene, yield losses caused by pests and diseases at farm level have beenreduced substantially.

  • Large quantities of superior clean planting materials that are early maturing (12-16 months as opposed to the conventional banana’s 2-3 years)
  • Larger bunch weights (30-45 kg as opposed to the 10-15 kg from conventional material)
  • Higher annual yield per unit of land (40-60 tons per hectare as opposed to the 15-20 tons previously realized with conventional material
  • And higher annual yield per unit of land

Furthermore, regularity in orchard creation and simultaneous plantation expansion made it easier to coordinate marketing efforts in the field. It also provided the opportunity to turn banana farming from a purely subsistence activity into a profitable commercial venture, if desired. The project’s cost-benefit study revealed that transgenic banana cultivation is more profitable as an enterprise than traditional banana farming, which is a promising development. In addition, the project has mostly benefited women who tend the crop, so contributing to the reduction of the gender gap.

Benefits of TC technology for rice farmers in West Africa (Source: WARDA)

Over the course of several decades, scientists have fantasized about fusing the ruggedness of the African rice species (Oryza glaberrima) with the productivity of the Asian rice species (Oryza edulis) (Oryza sativa). However, the two are diametrically opposed. Attempts to cross them were unsuccessful since the offspring produced were all infertile. When rice breeders from the West Africa Rice Development Association (WARDA) faced infertility issues in the 1990s, they resorted to biotechnology in an attempt to address the problem.

Scientists were able to cross these two species thanks to advancements in agricultural research.

Once the fertility of the offspring had been enhanced (typically after several cycles of back-crossing), anther cultivation was employed to double the gene complement of the male sex cells (anthers) and, as a result, generate true-breeding plants, which were then sent to the field.

Some of the new plants blended the yield characteristics of the sativa parent with the characteristics of the glaberrima parent to produce hybrids with higher yields. NERICAs are characterized by the following qualities in general:

  • Wide and drooping leaves that conceal weeds in their early stages of development
  • Panicles or grain heads that are taller and have ‘forked’ branches that can carry up to 400 grains
  • Moretillers with robust stems that can support and hold securely the heavy grainheads
  • Rice yields as high as 2.5 tons per hectare with low inputs — and 5 tons or more with only a minimal increase in fertilizer usage (amounting to a 25 percent to 250 percent increase in production)
  • Matures 30 to 50 days earlier than current varieties, allowing farmers to plant additional crops of vegetables or legumes
  • And matures 30 to 50 days earlier than current varieties, allowing farmers to plant additional crops of vegetables or legumes. It grows higher than other rice types and is more resistant to pests and drought than most others. thrives well on barren and acidic soils—which account for 70% of WestAfrica’s upland rice region
  • Contains 2% more protein per kilogram of body weight than their African or Asian ancestors

NERICAs were soon embraced by farmers as a result of their widespread success. The new rices were thought to span around 8,000 hectares in Guinea in 2000, with 5000 ha under cultivation by 20,000 farmers under the supervision of a national extension organization, according to estimates. It was anticipated that 330,000 hectares (ha) of NERICAs would be planted in 2002, which would be adequate to cover the country’s own seed requirements while also providing a surplus for sale to neighboring nations.


Anther: The most important male reproductive structure, in which pollen is produced and preserved. Apical meristems are found at the tips of roots and stems, where new cells are produced. DNA is a molecule present in the cells of living beings that stores genetic information (also known as genetic material). In plant breeding, embryo rescue refers to a series of tissue culture procedures that are used to allow an unfertilized immature embryo arising from an interspecific cross to continue growing and developing until it may be regenerated into a full plant.

What is Plant Tissue Culture and how does it work? It is possible to create new platelets by using plant material in a growth media, which is called Plant Tissue Culture. An very specialized and carefully regulated environment is used to cultivate and grow the starting plant material. The Tissue Culture Process, also known as micropropagation, is a technique that allows you to produce numerous homogeneous plants in a short period of time. A benefit of this procedure is that it may be used by impoverished nations to enhance agricultural yields, by individual at-home growers who want to create consistent quality, and by enterprises that want to manufacture identical clones of a species for a profit.

  1. The effectiveness of the tissue culture procedure is highly dependent on the availability of a sterile environment and a suitable growth media.
  2. This procedure is often more faster, and farmers may generate a large number of plants in a short period of time.
  3. Examine the benefits and drawbacks of the tissue culturing procedure.
  4. When it comes to adopting the tissue culture procedure, there are various benefits to consider.
  • In a short period of time, the new plantlets can be raised to maturity. Only a little quantity of plant tissue is required at the start of the process. New plantlets and plants have a higher likelihood of being free of viruses and illnesses than their predecessors. The procedure is not dependent on the seasons and can be carried out at any time of the year. You simply require a tiny amount of area to complete the procedure (ten times the number of plants in one-tenth the amount of space)
  • When applied on a wider scale, the tissue culture procedure contributes to the availability of novel subspecies and varieties to the consumer market. It is more successful for those who want to grow difficult plants, such as specialized orchid breeds, using the tissue culture procedure than than standard soil cultivation methods

Plant Growth Regulators in Tissue Culture is a related topic.

Disadvantages of Tissue Culture

  • Tissue culture may necessitate more work and result in a higher financial outlay. Because of the sort of environment in which the plants are produced, there is a possibility that the propagated plants will be less disease resistant. It is critical that the material be tested prior to being cultured
  • Failing to do so might result in the new plants becoming infected with the pathogen that was missed during screening. While the success rate with tissue culture is high if the proper protocols are followed, there is no assurance that the process will be successful. There is still a potential that the procedure will cause a secondary metabolic chemical reaction, causing the growth of the new explants or cells to be slowed, if not completely destroyed

As you can see, the positives appear to exceed the drawbacks in this case study. Getting started with DIY tissue culture may necessitate a little investment of time and money, but the benefits far transcend any initial investment of money.

Taking a look at the Tissue Culture Process, let’s try to simplify some of the more difficult words into something that’s a little more palatable. Let’s start from the beginning: there are two basic categories of cultures: indigenous and nonindigenous.

  • Primary culture refers to healthy tissues that have been taken from live substances or from living creatures. According on the procedure used in plant tissue culture, this might be either the leaves or other parts of the plant being cultured.
  • Growing Established Cell Lines: This form of tissue culture involves the growth of primary cells that have already been mutated (even from tumors or biopsies) and are capable of reproducing themselves.

What Makes Tissue Culture So Great?

A vast range of species may be reproduced via tissue culture, and it has a wide range of uses in the field of medicine. The yield of a plant can be greatly boosted in a short period of time by employing the tissue culture procedure. It is also possible to genetically modify a plant such that it develops resistant to certain illnesses and viral infections. Growers may ensure that their plants have extremely particular features by genetically modifying them. In many circumstances, corporations and people would propagate the plants in order for them to have certain characteristics that are more profitable for their business or more attractive for their own personal usage.

Finally, the tissue culture process is based on the plant’s inherent capacity to regenerate cells fast, and these rejuvenated cells are duplicates of the original cells, which are referred to as clones in most cases.

tissue culture

When bits of tissue from an animal or plant are transplanted to an artificial environment where they may continue to exist and function, this is referred to as tissue culture. Alternatively, the culturedtissue might be made up of a single cell, a population of cells, or a full or portion of an organ or organ organ. It is possible for cells grown in culture to proliferate; change in size; change in shape; change in function; display specialized activity (muscle cells, for example, may contract; or interact with other cells).

Historical developments

German scientist Wilhelm Roux attempted the first tissue culture experiment in 1885, growing tissue from a chick embryo in warm salt solution. Roux’s experiment was a success, and tissue culture became widely used after that. Nevertheless, it was not until 1907 when an American naturalist named Ross G. Harrison confirmed the development of frognerve cell processes in the presence of clotted lymph. Harrison’s approach was later improved upon by French surgeon Alexis Carreland and his colleague Montrose Burrows, who reported their early findings in a series of articles published in 1910–11, detailing their initial breakthroughs.

Following that, a number of experimenters were successful in growing animal cells, employing a range of bodily fluids as culture medium, including lymph, blood serum, plasma, and tissue extracts, among others.

Because of these achievements, researchers were able to produce and maintain human embryonic stem celllines, which helped them get a better knowledge of human biology and made significant advancements in therapeutics and regenerative medicine.

Culture environments

Cells may be cultured in a culture medium of biological origin, such as blood serum or tissue extract, in a culture medium of chemical definition, or in a combination of the two media types. A medium must contain the right amounts of the nutrients required by the cells under investigation, as well as be acidic or alkaline in the appropriate manner. Individual cell layers on a glass or plastic surface, as well as a suspension in a liquid or semisolid media, are the most common ways in which cultures are developed.

It is necessary to maintain sterile conditions in order to avoid contamination with germs.

Under most cases, single cells germinate and form colonies within 10 to 14 days of being placed in culture conditions.

Primary cultures and established cell lines

There are two types of cultures: primary (mortal) cultures and cultures of established (immortal) cell lines. Primary (mortal) cultures are the most common type of culture. Basic cell, tissue, and organ cultures are made up of normal cells, tissues, and organs that have been excised directly from tissue that has been harvested by biopsy from a living creature. Primary cultures have the benefit of closely replicating the normal function of the cell, tissue, or organ under investigation. However, the longer the samples are kept in culture, the greater the number of mutations they acquire, which can result in alterations in chromosomal structure as well as cell function.

Cells go through an aging process in which they reproduce for only 50 to 100 generations at a time, after which their reproduction rate drops dramatically.

Cell lines that have been created, on the other hand, may be maintained forever.

Cells in established lines accrue mutations over time, in a similar way as cells in initial cultures, and these mutations can alter the nature of the cells.

The DNA profile of the grown cells is compared to a known or standard profile for that cell line, which is known as authentication, in order to determine whether or not the cells are of that line.

Plant Tissue Culture

Tissue culture and cell culture of plants are used to describe the sterile development and multiplication of plant cells, tissues, and organs in a laboratory setting. Plant cells cultivated in nutritional medium in an artificial environment may be clonally propagated at a large scale, allowing for the production of more mature and disease-free plants in a shorter amount of time. Molecular genetic engineering, plant breeding, horticulture production, and environmental conservation all benefit from the ability to produce high-quality, homogeneous planting materials quickly.

A gel substrate, such as Murashige and Skoog (commonly referred to as MS media, MSO, or MS0), or Gamborg B5 medium, is used in a variety of typical plant cell culture techniques, including seed culture, meristem culture, callus culture, bud culture, and other types of plant cell culture.

Depending on the exact plant requirements, the plant culture medium formulation may comprise macronutrients, micronutrients, vitamins and organic supplements, amino acids and nitrogen supplements, plant growth hormones and plant growth regulators (PGRs), among other things.

Plant tissue cultures

Plant tissue cultures are a useful method for studying cell wall production in live cells in vivo because they are easy to grow and maintain. Tissue cultures also give cells and culture material that may be used to isolate enzymes and cell wall polymers for further investigation. Tissue cultures including tracheary element differentiation or extracellular lignin production have yielded valuable information on a variety of features of xylem and lignin formation, including the creation of xylem fibers.

Using Zinnia elegans mesophyll cells as a case study, we describe the creation of a xylogenic culture of these cells.

What is Plant Tissue Culture

LHS are used to induce onion tissue culture by allowing callus tissue to proliferate on seedling tissue and develop into an isolated callus in culture (RHS). In tissue culture systems, plant cells can be cultivated in isolation from entire plants in order to study their behavior. Rather than the properties of other plant cell types, the cells have the characteristics of callus cells. In the event that a plant is injured, these are the cells that develop on the cut surfaces, which progressively cover and seal the damaged region.

In the right conditions, pieces of plant tissue will slowly split and expand into a colorless mass of cells, which will eventually become a plant. These are the ones:

  • Initiated from the most appropriate plant tissue for the particular plant variety
  • A high concentration of auxin and cytokinin growth regulators in the growth media
  • A growth medium containing organic and inorganic compounds to sustain the cells
  • Aseptic conditions during culture to prevent competition from microorganisms
  • And a high concentration of auxin and cytokinin growth regulators in the growth media.

Plant cells can grow on a solid surface as friable, pale-brown lumps (known as callus), or they can develop as single cells or tiny clusters of cells in a liquid media, known as a suspension culture. These cells can be maintained forever if they are sub-cultured into fresh growth media on a regular basis. Tissue culture cells are often devoid of the distinguishing characteristics found in the majority of plant cells. A tiny vacuole, the absence of chloroplasts and photosynthetic processes, and the morphological or chemical characteristics that identify so many cell types within a complete plant are all lacking from these cells.

It is also possible to stimulate the re-differentiation of tissue grown cells into entire plants by making changes to the growing medium.

The physiological condition of the plant has an impact on its reaction to attempts to commence tissue culture, and this is something that should be considered.

The source, which is referred to as an explant, may be governed by the reason for which the tissue culture is being performed.

Moreover, the plants themselves must be actively developing and not on the verge of entering a dormant state.

Often, each variant of a species will have its own set of cultural requirements that must be met.
