Tissue Culture: The growth of tissues of living organism in a suitable culture medium (in vitro)I is called tissue, culture. Tissue culture has been exploited to create genetic variability from which crop plants can be improved, to improve the state of health of the planted material and to increase the number of desirable germplasms available to the plant breeder. Abstract. Essay # 1. Tissue culture will continue to playa key role in the genetic-engineering process for the foreseeable future, especially in efficient gene transfer and transgenic plant recovery (Hinchee et al. salt or drought tolerance or disease resistance, can be isolated in a short duration. M. Plant tissue culture refers to growth of plant tissues in a suitable culture medium. Taking advantage of known genetic diversity could facilitate this, and appropriate combinations were achieved through recombinations brought about by the sexual process (hybridization). Tissue culture is alternatively called cell, tissue and organ culture through in vitro condition. You can change your ad preferences anytime.
