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 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. […]
