[Effects of modulation of abscisic acid during somatic embryogenesis in Lycium barbarum L].

Abstract

Using Enzyme Linked Immunosorbent Assay (ELISA) method, we determined the ABA contents of different stages in somatic embryogenesis. The results showed that endogenous ABA contents increased to maximum value twice during somatic embryogenesis. After first maximum value of ABA contents embryogenic cells were observed in callus, and simultaneously, there was a specific protein of somatic embryogenesis investigated by SDS-PAGE. This protein accumulates preferentially in embryogenic callus but not in transferred callus. So it is suggested that ABA could promote the expression of specific genes and the synthesis of embryogenic protein during somatic embryogenesis in Lycium barbarum L. and ABA play an important role in globular stage as well. In addition, treatment of non-embryogenic activity callus with 4 mumol/L exogenous ABA could stimulate somatic embryogenesis. And the ABA function mechanism in relation to somatic embryogenesis was discussed.
