Mechanisms of Plant Sensing Drought Signals

doi:10.13560/j.cnki.biotech.bull.1985.2023-0763

Abstract

Abstract:

Drought causes osmotic stress and is the most serious natural disaster leading to crop failure. Ever since Darwin studied how plants sense and respond to drought, we have understood the mechanism of ABA（abscisic acid）signaling and gained some clues about drought and osmotic stress sensing and signaling in plants. In this review, we summarized recent advances in plant osmotic stress sensing and signaling. We proposed the putative manners of signal inputs during drought and osmotic stresses and discussed how plants sense and transduce these signals. We also discussed the core scientific questions and made perspective about the future directions in this field, aiming to provide clues for crop genetic improvement with drought resistance.

Key words: drought stress, osmotic stress signaling, cell wall signaling, membrane tension, macromolecular crowding
