Journal ArticleDOI
Control by ethylene of arginine decarboxylase activity in pea seedlings and its implication for hormonal regulation of plant growth.
TL;DR: Reducing the endogenous level of ethylene in the tissue by hypobaric pressure, or by exposure to light, as well as interfering with ethylene action by treatment with silver thiosulfate or 2,5-norbornadiene, caused a gradual increase in the specific activity of arginine decarboxylase in the apical tissue of the etiolated seedlings.
Journal ArticleDOI
Involvement of Polyamines in the Development and Ripening of Avocado Fruits
Leo Winer,Akiva Apelbaum +1 more
TL;DR: Addition of putrescine or spermine to avocado fruit tissue inhibited the biosynthesis of the ripening hormone, ethylene, by inhibiting both the activity of 1-aminocyclopropane-1-carboxylic acid (ACC) synthase and the conversion of ACC into ethylene.
Journal ArticleDOI
Influence of Ethylene on S-adenosylmethionine Decarboxylase Activity in Etiolated Pea Seedlings
TL;DR: The possibility that ethylene at the endogenous level might regulate S-adenosyl-L-methionine decarboxylase activity is discussed, as it was detected in crude extract from the plumular hook of etiolated pea seedlings.
Journal Article
Effect of Inhibitors and Stimulators of Ethylene Production on Gall Development in Meloidogyne javanica-Infected Tomato Roots.
TL;DR: It is suggested that this plant hormone plays a major role in the development of M. javanica-induced galls and ethylene affects gall size by enhancing parenchymatous tissue development and allows expansion of giant cells and the nematode body by reducing tissue lignification.
Journal ArticleDOI
Inhibition by polyamines of macromolecular synthesis and its implication for ethylene production and senescence processes.
TL;DR: In this article, applied diamines and polyamines inhibited the incorporation of radioactively labeled leucine and uridine into trichloroacetic acid-insoluble material in apple (Malus domestica Borkh, cv Golden Delicious) fruit tissue.
