Two cDNA clones, pOS103 and pOS137, were isolated which code for distinct a-amylase
isozymes in germinating rice seeds. Sequence analysis indicated that the clones encode
polypeptides of approximately 48 kDa, both of which possess a signal peptide involved in ...

A starch-hydrolyzing enzyme present in extracts of the cotyledons of germinating peas has been
purified over 3400-fold. Several independent criteria show that this activity is due to an amylase
of the α-type (α-1,4-glucan-4-glucanohydrolase, EC 3.2.1.1). The enzyme exhibits ...

We have analyzed the in situ hybridization of α-amyl-ase genes in rice and barley seeds. There
are some similarities in the expression pattern between the rice and barley α-amylase
genes, RAmylA and Amyl. Both are gib-berellin-inducible, the expression of these genes ...

Abstract It is well known that abscisic acid (ABA) antagonizes gibberellin (GA)-promoted
seed germination. Recent circumstantial evidence suggests that salicylic acid (SA) also
inhibits seed germination in maize and Arabidopsis. Our study shows that SA blocks ...
