In other words, it is an in vitro culture of plant cells or tissues on artificial nutrient media under aseptic conditions, in glass containers.
This is a technique by which new plants can be raised on artificial nutrient media by the use of plant parts or cells. These small parts can be pollenleaves, seed, root tip, embryo, etc. Since all the above organs or cells contain the same genetic material as that of parent plants, a new plant can be grown.
Media for tissue culture : Nutrient media plays an important role in tissue culture. It is very vital for the proper and timely growth of cells and their multiplication.
Since nutrient media is the only source of nutrition, it should supply all the basic requirements. These include carbohydrates, amino acids, mineralshormones, and salts, etc at proper proportions.
It should be sterile and be non-toxic to the tissue or cell under culture. All the ingredients of the media are to be sterile hence one can use autoclave or membrane filters based on their thermal resistance power. Tissue culture media preparation should be done in aseptic rooms and conditions. Vitamin source :. Also one can include activated charcoal to adsorbs impurities from media.
Tissue culture equipment like Complete air-conditioned lab, laminar airflow, autoclave, BID incubators, Shakers are also needed. This helps the cell wall and tissue surfaces to be free from any bacterial or fungal infections.
Care should be taken during their handling, transfer, etc. Then the tissue is placed in media in a conical flask or volumetric flask and incubated with proper oxygen supply and the right temperature. The gas should be free from contamination and also aseptic.
The rate and pressure of the flow of gas into the chamber of tissue culture should be optimal. This can be transplanted to the greenhouse. Tissue culture plants are highly sensitive to tolerate natural environment conditions. They have to be slowly adapted to normal atmosphere. So first they are to be grown in greenhouses. When a cell or tissue is incubated in nutrient media, it shows phase difference in growth.Biotech Articles.

Plant tissue culture is used to produce clones of plant in a method called micopropagation. Plant tissue culture relies on the fact that many plant cells have the ability to regenerate into a whole plant in a process called totipotency. Single cells without cell walls protoplastspieces of leaves, stems or roots can often be used to generate a new plant on culture media given the required nutrients and hormones.
The plant part obtained from a plant to be cultured is called explant while the main plant it is obtained from is called mother plant. Explant can be taken from different plant parts such as shoots, leaves, stems, flowers, roots, single undifferentiated cells etc. The tissue is grown in sterile containers inside Petri dish, test tube or flasks in a growth room with controlled temperature and light intensity. Living plant materials are usually contaminated on their surfaces or sometimes interior with microorganisms, so their surfaces are stressed in chemical solutions e.
The sterile explant are placed on the solid and liquid media are generally composed of inorganic salts, organic nutrients, vitamins and plant hormones.
Solid media are prepared from liquid media with the addition of gelling agent agar. The composition of the medium, particularly the plant hormones and the nitrogen source have profound effects on the morphology of the tissues that grow from the initial explant.
For instance, an excess of auxin will result in a proliferation of roots while an excess of cytokinin may yield to shoots proliferation. A balance of both auxin and cytokinin will often produce an unorganised growth of cells called callus, but the morphology of the outgrowth will depend on the plant species as well as the medium composition.
They include: 1. Commercial production of plants used as landscape, potting and florist subject which uses meristem and shoot culture. To conserve endangered plant species to avoid extinction. Use of meristem tip cultures to produce clean plant material from virus stock such as potatoes. To produce disease free plants due to its production in sterile environment 6.
For chromosome doubling and induction of polyploidy for example doubled haploid, tetraploids, and other forms of polyploids. This is usually achieved by application of antimitotic agents such as Colchicine or Oryzalin. To quickly produce mature plants 2. The production of multiples of plants in the absence of seeds or pollinators to produce seeds 3.
The production of exact copies of plants that produce particularly good flowers, fruits or have other desirable traits 4. The production of plants in sterile conditions with greatly reduced chances of transmitting diseases, pests and pathogens 5. The production of plants from seeds that otherwise have low chances of germinating and growing.
To mass propagate plants for commercial use. It also produces disease-free plants due to its method of growth. The setting up of a plant tissue culture laboratory is very expensive including it's machines and reagents 2. The experiments of tissue culture must be handled by highly trained people as the procedure requires special care and careful observations. If all the plants are genetically similar, there is reduction in genetic diversity.
If a plant is susceptible to disease, all the plants of this cloned stock will share this undesirable trait and be susceptible to that particular disease. The procedures depends on the type of species being cultured, hence there is need for trail and error method for any new species if there is no review about that species.Read this article to learn about the plant tissue culture media and its types, constituents, preparation and selection of a suitable medium.
Culture media are largely responsible for the in vitro growth and morphogenesis of plant tissues.
The success of the plant tissue culture depends on the choice of the nutrient medium. In fact, the cells of most plant cells can be grown in culture media.
Basically, the plant tissue culture media should contain the same nutrients as required by the whole plant. It may be noted that plants in nature can synthesize their own food material. However, plants growing in vitro are mainly heterotrophic i. Thus, the composition of a medium is formulated considering the specific requirements of a given culture system.
The media used may be solid solid medium or liquid liquid medium in nature. The selection of solid or liquid medium is dependent on the better response of a culture.
The composition of the most commonly used tissue culture media is given in Table Murashige and Skoog MS originally formulated a medium to induce organogenesis, and regeneration of plants in cultured tissues. These days, MS medium is widely used for many types of culture systems. Developed by Gamborg, B5 medium was originally designed for cell suspension and callus cultures. At present with certain modifications, this medium is used for protoplast culture.
Chu formulated this medium and it is used for cereal anther culture, besides other tissue cultures. This medium was developed by Nitsch and Nitsch and frequently used for anther cultures.
Among the media referred above, MS medium is most frequently used in plant tissue culture work due to its success with several plant species and culture systems. When a medium is composed of chemically defined components, it is referred to as a synthetic medium.
Plant Tissue Culture Media
On the other hand, if a medium contains chemically undefined compounds e. Synthetic media have almost replaced the natural media for tissue culture. Many elements are needed for plant nutrition and their physiological functions. Thus, these elements have to be supplied in the culture medium to support adequate growth of cultures in vitro.
A selected list of the elements and their functions in plants is given in Table A wide range of mineral salts elements supply the macro- and micronutrients. The inorganic salts in water undergo dissociation and ionization.
Consequently, one type of ion may be contributed by more than one salt. The six elements namely nitrogen, phosphorus, potassium, calcium, magnesium and sulfur are the essential macronutrients for tissue culture. The ideal concentration of nitrogen and potassium is around 25 mmol I -1 while for calcium, phosphorus, sulfur and magnesium, it is in the range of mmol I —. For the supply of nitrogen in the medium, nitrates and ammonium salts are together used.
Although their requirement is in minute quantities, micronutrients are essential for plant cells and tissues. These include iron, manganese, zinc, boron, copper and molybdenum. Among the microelements, iron requirement is very critical.
Chelated forms of iron and copper are commonly used in culture media. Plant cells and tissues in the culture medium are heterotrophic and therefore, are dependent on the external carbon for energy.
Among the energy sources, sucrose is the most preferred.Copy embed code:. Automatically changes to Flash or non-Flash embed. WordPress Embed Customize Embed. URL: Copy.

It is then placed inside the tissue culture vessel dish,jar, etc. Differentiation De- : The physiological and morphological changes that occur in a cell, tissue, or organ during development. Janola,Chlorox, etc.
The substrate use for biotransformation may be natural or synthetic. The reaction may be single or multistep reaction.
The biotransformation of digitoxin to digoxin using D-lanata cell which are unable to produce cardiac glycosides De-novo is the most famous examples of biotransformation. This is a commercial interest, since, digoxin is a better drug for heart disease than digitoxin. Such material can be used to generate undiscovered novel compounds in addition to potentially known compounds.After you enable Flash, refresh this page and the presentation should play.
