Abstract:

This review highlights the recent advances concerning the role of polyamines and brassinosteroids in stress tolerance of plants with a special accent on drought. Alterations of the endogenous polyamine and brassinosteroid levels and their function in alleviation of drought stress are discussed. Possibilities for application of exogenous polyamines and brassinosteroids to lessen the stress injuries and to increase drought tolerance are also summarized. Genetic and molecular approaches for improving plant tolerance to drought via modification of polyamine levels and involvement of brassinosteroids in signal transduction pathways under stress are presented. Interaction of polyamines and brassinosteroids with phytohormones and osmolytes under drought stress is reviewed. We describe also the recent investigations in Bulgaria and Egypt concerning the modulation of plant reactions to drought stress by application of polyamines and brassinosteroids.
