Abstract Alterations in free and conjugated polyamines (PAs) and the enzymes involved in their biosynthesis, namely arginine decarboxylase, ornithine decarboxylase and S-adenosyl methionine decarboxylase have been reported to occur during cell division, growth, embryogenesis and rhizogenesis in an array of plant materials. However, the relationship, if any, between them and all these processes has not yet been established. It seems that specific PAs at specific concentration ranges are required during critical stages of growth and morphogenetic events. Furthermore, the effects of PA biosynthesis inhibitors vary considerably at different developmental stages of the same tissue. The present review deals with the available information about the possible role of PAs in aforesaid physiological processes.
