Abiotic stress conditions adversely affect plant growth, resulting in significant decline in crop productivity. To mitigate and recover from the damaging effects of such adverse environmental conditions, plants have evolved various adaptive strategies at cellular and metabolic levels. Most of these strategies involve dynamic changes in protein abundance that can be best explored through proteomics. This review summarizes comparative proteomic studies conducted with roots of various plant species subjected to different abiotic stresses especially drought, salinity, flood, and cold. The main purpose of this article is to highlight and classify the protein level changes in abiotic stress response pathways specifically in plant roots. Shared as well as stressor-specific proteome signatures and adaptive mechanism(s) are simultaneously described. Such a comprehensive account will facilitate the design of genetic engineering strategies that enable the development of broad-spectrum abiotic stress-tolerant crops.
非生物胁迫条件会对植物生长造成不利影响，导致作物产量显著下降。为了减轻和恢复这些不利环境条件的破坏性影响，植物在细胞和代谢水平上进化出了各种适应策略。这些策略大多数都涉及蛋白质丰度的动态变化，这可以通过蛋白质组学来最好地研究。本综述总结了对不同非生物胁迫（特别是干旱、盐度、洪水和寒冷）下各种植物根进行的比较蛋白质组学研究。本文的主要目的是强调并分类植物根中对非生物胁迫反应途径的蛋白质水平变化。同时描述了共享和胁迫特异性的蛋白质组特征和适应机制。这种全面的描述将有助于设计遗传工程策略，从而开发广谱非生物胁迫耐受作物。
