In this article we will discuss about the Definition and Factors of Organogenesis. Definition of Organogenesis: From cells of tissue culture various organs, such as, roots, stems, leaves or flowers may be initiated. This is called organogenesis. Such organ development does not require any pre-existing-initials. These new organs are formed in two stages. In the first phase (dedifferentiation) cells of [...]
The below mentioned article provides an short notes on Somatic Embryogenesis. The formation of embryos (embryoids) in plant tissue culture was first reported by Steward ('59) in cell suspension culture of carrot. Formation of embryoids in callus culture of carrot on agar medium was reported by Reinert ('59). Vegetative embryoids have been noticed in tissue culture of various plants, such [...]
The below mentioned article provides a study notes on Single Cell Clone. By culturing a single isolated cell single cell clone can be obtained. Single cell clones derived from callus or suspension culture are heterogenous. They differ from one another in shape, texture, friability, colour, growth and morphogenetic potential etc. Working with Nicotiana tabacum L. Winsconsin ('38), Murashige and Nakamo [...]
