Transgenic plants – prospects and problems

Genetic engineering leading to the development of transgenic organisms is emerging as the latest thrust area of biotechnology related research. New methods of gene transfer have made it possible to transfer genes to unrelated species, thus eliminating some of the difficulties of conventional methods of crop improvement. Conventional genetic management practices, such as hybridization are possible only with sexually compatible species thus limiting its scope, whereas the genetic manipulation has unlimited scope. Today, the DNA of plants can be directly modified by recombinant DNA (R‐DNA) techniques. New varieties of agronomical plants possessing any possible combination of desired characteristics can be theoretically developed by this technology. The principal objective of plant biotechnology is to increase the biological productivity by creating new varieties of cultivated plants. The basis for change in traits by transgenesis is identification, characterization, isolation, purification and cloning of genes followed by the transfer to the target plant. Plant varieties with tolerance to several diseases, pathogens, pests, extreme climatic conditions, herbicides, environmental stress, senescence etc. have been produced by genetic engineering. These plants will undoubtedly play a significant role in feeding the world's population in the future
