Interactions of Brassinosteroids with Major Phytohormones: Antagonistic Effects
- 149 Downloads
Brassinosteroids (BRs) constitute an important class of signaling molecules capable of executing diverse functions ranging from plant growth, development, reproduction, and even stress tolerance. The recent literature on BRs has discussed these wide ranging roles and potentials of BRs. However, the maintenance of metabolic equivalents in the global context of other phytohormones is largely unknown. In this article, we have highlighted such interactive antagonistic cross-talks between BRs and other phytohormones which are crucial in growth regulation and abiotic stress tolerance. Such competitive interactions with BRs have been observed in the cases of abscisic acid, ethylene, auxin, gibberellins, salicylic acid, and even polyamines during physiological growth or abiotic stresses. The discussion largely presents the unique characters of plant molecular physiology and development regarding BR- and other phytohormone-mediated interactive antagonism.
