Ca-stimulated secretion of alpha-amylase during development in barley aleurone protoplasts.

Abstract

The effects of gibberellic acid (GA(3)) and Ca(2+) on the synthesis and secretion of alpha-amylase from protoplasts of barley (Hordeum vulgare L. cv Himalaya) aleurone were studied. Protoplasts undergo dramatic morphological changes whether or not the incubation medium contains GA(3), CaCl(2), or both. Incubation of protoplasts in medium containing both GA… (More)
