Growth of Isolated Mesophyll Cells of Arachis hypogaea in Simple Defined Medium in vitro.

Isolated mesophyll cells from leaflets of Arachis hypogaea can be cultured in a simple, defined liquid nutrient medium containing minerals, with an appropriate source of ammonia, sugar, 2,4-dichlorophenoxyacetic acid, and kinetin. The significance of such a simple medium in understanding the problems of cell metabolism, growth, and morphogenesis is discussed.
