Detailed explanation-1: -The genetically identical plants produced by plant tissue culture are collectively referred to as ‘somaclones’.
Detailed explanation-2: -Tissue culture involves the use of small pieces of plant tissue (explants) which are cultured in a nutrient medium under sterile conditions. Using the appropriate growing conditions for each explant type, plants can be induced to rapidly produce new shoots, and, with the addition of suitable hormones new roots.
Detailed explanation-3: -Through tissue culture the transformed cell can then be regenerated into an entire plant with each cell containing the transgene. The gene has become a permanent part of the transgenic plant’s genome and will be passed on to its progeny.
Detailed explanation-4: -A large space is not required to grow plants by tissue culture technique. The production of new varieties in the market place speeds up. This technique is being used for the production of ornamental plants such as dahlia, chrysanthemum, orchids, etc.
Detailed explanation-5: -Tissue culture can be used with any plant cells that have a characteristic known as totipotency; in other words, plant cells that can regenerate from a cell into complete, mature plants.
