The effects of (+)-8′,8′,8′-trifluoroabscisic acid (trifluoro-ABA) on α-amylase expression were studied in rice embryoless half-seeds, scutella, and suspension-cultured cells derived from the embryo, and the effects of the analog on sugar accumulation were also studied in scutella and suspension-cultured cells. Treatment with (+)-trifluoro-ABA strongly inhibited the gibberellic acid-inducible expression of α-amylase I-1 encoded by RAmy1A in the aleurone layers of embryoless half-seeds at the… CONTINUE READING
