(BS) Developed by Therithal info, Chennai. Tissue culture is used to develop thousands of genetically identical plants from one single parent plant known as soma clones, and this process is known as micropropagation. Although they tendto grow in discrete patches, these cells also grow attached to the substrate. Formation of new organs such as shoot and root is known as organogenesis. Swaminathan Research Institute (MSSRI), Chennai. The Department of Biotechnology (DBT), Government of India, New Delhi is playing a vital role in promoting research in the area of plant tissue culture. In order to control the quantity of each chemical element in the medium as precisely as possible,  pure water needs to be used.  Therefore, the water used in medium preparation needs to be distilled and deionized. toa method in which fragments of a tissue (plant or animal tissue) are introducedinto a new To do this it is necessary to set up an artificial environment in which the cells will grow.

This second edition sets the direction for future research on the basic aspects of plant tissue culture and its applications in the fields of secondary metabolite production and genetic engineering. Table 1 is a comparison of several media that are commonly used in plant tissue culture. The mechanism of callus formation is that auxin induce cell elongation and cytokinin induces cell division as a result of which masses of cells are formed. Fibroblastic - Thisincludes cells that tend to be bipolar/multipolar with elongated shapes. Plant tissue culture is a widely known technique for the production of large numbers of genetically identical plantlets. root, stem and .

Plant Tissue Culture Terminology Adventitious---Developing from unusual points of origin, such as shoot or root tissues, from callus or embryos, from sources other than zygotes. The method offers an advantage over other methods as it can be used to develop disease free plants from disease-rode plants by using their meristems (apical and axillary) as explants. Roots and shoots are differentiated from the callus. Such embryos are called somatic embryos result in the formation of young plantlet. This technique is also called micropropagation. Tissue culture is the growth of tissues or cells in an artificial medium separate from the parent organism.  It is widely used to produce clones of a plant in a method known as Micropropagation. bipolar structure having shoot and root) from the callus is called embryogenesis. 7.  Adjust pH (5.5-5.8 for most media) with KOH; View Video of ‘ADJUSTING THE pH’.
