低温是影响水稻地理分布生长、发育和生产力的主要因素。冷胁迫介导一系列生理和代谢变化，如叶绿素荧光、电解质渗漏、活性氧（ROS）、丙二醛（MAD）、蔗糖、脂质过氧化物、脯氨酸等代谢物的改变，植物内源激素脱落酸（ABA）和赤霉素（GA）也发生变化。本文综述了近年来水稻低温生理代谢变化、图位克隆和全基因组关联分析（GWAS）报道的冷胁迫相关位点和QTL的研究进展，以及水稻响应低温的一些分子机制。我们还讨论了水稻耐寒品种选育的前景。
Low temperature is a major factor affecting rice geographical distribution growth, development, and productivity. Cold stress mediates a series of physiological and metabolite changes, such as alterations in chlorophyll fluorescence, electrolyte leakage, reactive oxygen species (ROS), malondialdehyde (MAD), sucrose, lipid peroxides, proline, and other metabolites, plant endogenous hormones abscisic acid (ABA) and gibberellin (GA) also changes. In this review, we summarize the recent research progress on physiological and metabolic changes under low temperature, cold stress related loci and QTL reported by map -based cloning and genome-wide association analysis (GWAS), and some molecular mechanisms in response to low temperature in rice. We also discuss the future prospects on breeding cold tolerance varieties of rice.
