Brassinosteroids is a new group of plant growth regulators with significant growth promoting
influence which was first isolated and characterized from the pollen of Brassica napus L. Subsequently,
they were reported from monocots, dicots, gymnosperms, pteridophyte and alga. Brassinosteroids are
now considered as plant hormones with pleiotropic effects as they influence varied developmental
processes like growth, germination of seeds, rhizogenesis, flowering, senescence and all kinds of
stresses. This chapter reviews the effect of brassinosteroids in mitigating water and saline stresses.
Keywords: 24-epibrassinolide, abiotic stresses, drought resistance, drought stress, homobrassinolide,
osmotic stress.
