Abstract

To understand the molecular mechanism of gibberellin-dependent gene regulation, the effect of three phosphatase inhibitors on the germination of rice seeds and the expression of a target gene, the α-amylase gene, Osamy-c, were measured. We found that okadaic acid, microcystin-LR, and calyculin A, which are known to specifically inhibit Ser/Thr phosphatases 1 and 2A, strongly inhibit the expression of the Osamy-c and may be involved in the germination of rice seeds.
