摘要 世界范围内,农作物的产量都容易受到各种生物和非生物因素的影响,对植物逆境适应性反应机制的深入研究有助于我们采取新的措施,以提高作物的逆境适应性。以前通常认为植物适应逆境胁迫的机制主要涉及相关基因在转录水平的调节,然而,近来发现部分内源小RNAs(siRNAs),如miRNAs、nat-siRNAs和lsiRNAs不仅可以调节植物的生长发育,而且在植物逆境反应中具有重要作用。文章就这些内源小RNAs在氧、矿质元素、干旱、低温、脱落酸、机械、重金属、生物及其他环境因素胁迫中的作用机制做一概述。 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.
