作为固着生物,植物必须应对非生物胁迫,如土壤盐渍化、干旱和极端温度。核心胁迫信号通路涉及与酵母SNF1和哺乳动物AMPK相关的蛋白激酶,这表明植物中的胁迫信号是从能量感应进化而来的。胁迫信号调节对离子和水分运输以及代谢和基因表达重编程至关重要的蛋白质,以便在胁迫条件下实现离子和水分平衡以及细胞稳定性。了解胁迫信号和响应将提高我们增强作物抗逆性的能力,从而为不断增长的世界人口实现农业可持续性和粮食安全。
As sessile organisms, plants must cope with abiotic stress such as soil salinity, drought, and extreme temperatures. Core stress signaling pathways involve protein kinases related to the yeast SNF1 and mammalian AMPK, suggesting that stress signaling in plants evolved from energy sensing. Stress signaling regulates proteins critical for ion and water transport and for metabolic and gene-expression reprogramming to bring about ionic and water homeostasis and cellular stability under stress conditions. Understanding stress signaling and responses will increase our ability to improve stress resistance in crops to achieve agricultural sustainability and food security for a growing world population.
