Abstract
The expression of a papain-type proteinase, designated SH-EP, in cotyledons of Vigna mungo seedlings has been shown to require some factors in the emb ryonic axes. Gibberellin Al (GA,) and GA(20) were identified by GC-MS in em bryonic axes of V mungo seedlings. The level of accumulation of SH-EP in co tyledons of V mungo seedlings was greatly reduced by treatment of the seeds with uniconazole-P, an inhibitor for GA biosynthesis. The reduced level of accumulation of SH-EP in cotyledons by uniconazole-P was recovered by exog enous application of GA(1) and GA(20) to the seedlings.
