Somatic Hybridization Somatic cell means body cells i.e., other than the reproductive cells. In this method, the somatic cells of two varieties or species are fused together. For doing so, first the cell walls are removed by a certain enzyme. The plant cells lacking the cell wall are called protoplasts. The protoplasts of the selected […]
Protoplast Technology
Protoplast Technology The term protoplast was introduced by Hanstein in 1880. It refers to the cellular content excluding cell wall or can also be called as naked plant cell. It is the living matter enclosed by a plant cell membrane. The first isolation of protoplasts was achieved by Klercker (1892) employing a mechanical method. […]

Transgenics in Crop Improvement Topics Covered in Transgenics Resistance to biotic stresses Insect Resistance Virus Resistance Disease Resistance Herbicide Resistance Transgenic plants are the ones whose DNA is modified using genetic engineering techniques. A transgenic plant contains a gene or genes that have been artificially inserted. The inserted gene sequence is known as transgene, it may […]
