Molecular characterization of catalytic-subunit cDNA sequences encoding protein phosphatases 1 and 2A and study of their roles in the gibberellin-dependent Osamy-c expression in rice
IEPA.d107.s248
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 alpha-amylase gene, Osamy-c, were measured
IEPA.d107.s249
To further understand the possible role of protein phosphatases 1 and 2A in the GA-dependent expression of Osamy-c, we isolated cDNA clones encoding protein phosphatase 1 and protein phosphatase 2A from a rice aleurone cDNA library
IEPA.d107.s250
Taken together, our results suggest that protein phosphatases PP1 or PP2A are involved in the GA-dependent expression of the rice Osamy-c gene, though the PP1 or/and PP2A enzymatic activities as well as mRNA levels do not increase upon GA3 treatment
