Gibberellic acid stimulates acid invertase secretion in pea ovary protoplasts.


Protoplasts purified from mesocarp of nonpollinated pea (Pisum sativum L.) ovaries released acid invertase to the incubation medium. The association of the acid invertase with microsomal fractions, and the sensitivity to energy-metabolism inhibitors and to tunicamycin, indicated the secretory nature of the release process. In the presence of GA3 (10 microM… (More)
