The intensification of global climate change and industrialization has exacerbated abiotic stresses on crops, particularly rice, posing significant threats to food security and human health. The mechanisms by which rice responds to these stresses are complex and interrelated. This review aims to provide a comprehensive understanding of the molecular mechanisms underlying rice's response to various abiotic stresses, including drought, salinity, extreme temperatures, and heavy metal pollution. We emphasize the molecular mechanisms and structural roles of key proteins involved in these stress responses, such as the roles of SLAC1 and QUAC1 in stomatal regulation, HKT and SOS proteins in salinity stress, heat shock proteins (HSPs) and heat stress transcription factors (HSFs) in temperature stress, and Nramp and ZIP transport proteins in response to heavy metal stress. This review elucidates the complex response networks of rice to various abiotic stresses, highlighting the key proteins and their related molecular mechanisms, which may further help to improve the strategies of molecular breeding.
全球气候变化和工业化的加剧使作物（尤其是水稻）遭受的非生物胁迫恶化，对粮食安全和人类健康构成重大威胁。水稻对这些胁迫的响应机制复杂且相互关联。本综述旨在全面了解水稻对各种非生物胁迫（包括干旱、盐度、极端温度和重金属污染）响应的分子机制。我们强调了参与这些胁迫响应的关键蛋白质的分子机制和结构作用，例如SLAC1和QUAC1在气孔调节中的作用、HKT和SOS蛋白在盐胁迫中的作用、热休克蛋白（HSPs）和热应激转录因子（HSFs）在温度胁迫中的作用，以及Nramp和ZIP转运蛋白在响应重金属胁迫中的作用。本综述阐明了水稻对各种非生物胁迫的复杂响应网络，突出了关键蛋白质及其相关分子机制，这可能进一步有助于改进分子育种策略。
