TL;DR: This chapter will focus on polyamine biosynthesis, oxidation, conjugation processes, mainly to hydroxycinnamic acids, and compartmentation of enzymes, substrates and products, giving an overview about recent results especially in higher plants.

TL;DR: Results showed an up-regulation of the stilbene synthase demonstrating that MeJA stimulated the synthesis ex-novo of this protein, and stimulated the release in the culture medium especially of cis-resveratrol.

TL;DR: Investigation of polyamine levels, activities and regulation of biosynthetic enzymes in different organs of Arabidopsis thaliana L. (ecotype Columbia) wild-type suggests the presence of an interconversion of acetylspermidine to putrescine via a putative polyamine oxidase.

TL;DR: The results indicate that polyamines may play a significant role at least in some stages of root formation in Prunus avium micropropagation, and the polyamine and ethylene biosynthetic pathways seem to be competitive.

TL;DR: In this paper, the concentrations of three classes of polyamines, trichloroacetic acid-soluble (free), TCA-insoluble conjugated (to small molecules) and TCA solv soluble conjugates (to macromolecules), were examined during de novo floral and vegetative bud formation in thin cell layers of Nicotiana tabacum L. cv.
