Crop yields are significantly reduced by biotic and abiotic stresses throughout the world. A better understanding of adaptive responses will lead to new strategies for improving plant stress tolerance. The molecular response of plants to stresses has been often considered as a complex process mainly based on the modulation of transcriptional activity of stress-related genes. Nevertheless, recently discovered endogenous small RNAs, such as miRNAs, nat-siRNAs and lisiRNAs, not only have a vital role in regulating plant development, but also have emerged as important players in plant stress responses. This review discusses recent advances in the field of small RNAs guided adaption to various stress responses, including oxidative stress, mineral nutrient deficiency, drought stress, salinity stress, ABA stress, mechanical stress, heavy metals stresses, biotic stresses, and other environmental stresses.
在全球范围内，生物和非生物胁迫显著降低了作物产量。更好地理解适应性反应将带来提高植物胁迫耐受性的新策略。植物对胁迫的分子反应通常被认为是一个复杂的过程，主要基于对胁迫相关基因转录活性的调节。然而，最近发现的内源性小RNA，如miRNA、nat-siRNA和lisiRNA，不仅在调节植物发育中起着至关重要的作用，而且在植物胁迫反应中也已成为重要角色。本文综述了小RNA介导适应各种胁迫反应领域的最新进展，包括氧化胁迫、矿质营养缺乏、干旱胁迫、盐胁迫、脱落酸胁迫、机械胁迫、重金属胁迫、生物胁迫和其他环境胁迫。
