The time of appearance and relative amounts of alpha-amylase mRNA in wild oat (Avena fatua L.) aleurone protoplasts incubated with 1 micromolar gibberellin A(4) (GA(4)) were closely correlated with the amounts of alpha-amylase enzyme secreted by the protoplasts. In the absence of GA(4), or when protoplasts were incubated with 25 micromolar abscisic acid (ABA) together with 1 micromolar GA(4) no...

The antioxidant activities of the ethanol extract, its benzene and chloroform fraction from seed aril of Myristica malabarica (Myristicaceae) were assessed in an effort to validate the hepatoprotective potency of this plant. The extract and the fractions showed scavenging of 1, 1-diphenyl-2picrylhydrazyl (DPPH) radical and inhibition of ABTS radical in vitro. Antioxidant activities of the extra...
