Reviews of the Physiological Roles and Molecular Biology of Polyamines in Higher Plants

Polyamines play multi-physiological roles in plant growth and development. Regulation of plant senescence, floral initiation and development fruit development and a lot of physiological responses to stress are involved in the reviews. On the basis of the brief reviews on the catabolism pathway of polyamine degradation in higher plants, emphases were placed on the advances of the physiological roles and molecular biology of polyamine in higher plants.
