Phytohormone-Mediated Stomatal Response, Escape and Quiescence Strategies in Plants under Flooding Stress

摘要: Generally, flooding causes waterlogging or submergence stress which is considered as one of the most important abiotic factors that severely hinders plant growth and development. Plants might not complete their life cycle even in short duration flooding. As biologically intelligent organisms, plants always try to resist survive under such adverse circumstances by adapting a wide array mechanisms including hormonal homeostasis. Under this mechanism, adapt through diverse morphological, physiological molecular changes, closing stomata, elongating petioles, hollow stems internodes, maintaining minimum activity store energy combat post-flooding continue normal Mainly, ethylene, gibberellins (GA) abscisic acid (ABA) are directly and/or indirectly involved homeostasis mechanisms. Responses specific genes transcription reactive oxygen species (ROS) maintain equilibrium between stomatal opening closing, fastest responses when encountering conditions. In review paper, sequential steps some hormone-dependent survival conditions have been critically discussed.
