Control of Phytopathogens by Inhibitors of Polyamine Biosynthesis
It is now clear that polyamines (PAs) are required for the normal growth and development of microorganisms as well as cells of higher animals and plants,1, 2, 3. In all organisms, putrescine (Put) is formed from ornithine via ornithine decarboxylase (ODC); in some microorganisms and in higher plants, Put may also be formed from arginine via arginine decarboxylase (ADC). Put is then transformed to the triamine spermidine (Spd) and the tetramine spermine (Spm) by successive enzyme-mediated aminopropyl transfers from S-adenosylmethionine (SAM).
