The activities of arginine decarboxylase (ADC; EC 4.1.1.19) and ornithine decarboxylase (ODC; EC 4.1.1.17) as well as polyamine content were examined in Phaseolus vulgaris L. cv. Taylor's Horticultural before and during anthesis, during fruit development and throughout vegetative growth. The specific activities of polyamine biosynthetic enzymes were highest in all rapidly growing tissues, e.g., root apices, hypocotyls, young internodes, young leaves, flower buds, young pods and pericarps. They were lowest in mature, non-growing tissues. Similarly, the content of the major polyamines (putrescine, spermidine, spermine) is highest in rapidly growing tissues, and lowest in mature tissue. These correlations reinforce the growing connection between polyamines and rates of cell division and metabolic activity during both vegetative and reproductive development.
