Abstract
Polyamines have been correlated with numerous plant processes, and the elucidation of their physiological role(s) has been a state-of the-art research topic in the recent years. Both their anabolism and catabolism seem to possess a regulatory role in development, stressing the necessity of their fine-tuning. Amongst the most important is the control of fruit-set and development. In this Chapter, the role of polyamines in the different stages of the grape berry development is discussed. In addition, references to other plant species are also included to strengthen the pan-species’ specific role of polyamines.
Keywords: Abscisic acid, Abscission, Hormone, Photosynthetic efficiency, Polyamine biosynthesis, Polyamines, Programmed cell death, Putrescine, Reactive oxygen species, Spermidine, Spermine.
