Sucrose non-fermenting-1 (SNF1)-related protein kinases (SnRKs) take their name from their fungal homologue, SNF1, a global regulator of carbon metabolism. The plant family has burgeoned to comprise 38 members which can be subdivided into three sub-families: SnRK1, SnRK2, and SnRK3. There is now good evidence that this has occurred to allow plants to link metabolic and stress signalling in a way that does not occur in other organisms. The role of SnRKs, focusing in particular on abscisic acid-induced signalling pathways, salinity tolerance, responses to nutritional stress and disease, and the regulation of carbon metabolism and, therefore, yield, is reviewed here. The key role that SnRKs play at the interface between metabolic and stress signalling make them potential candidates for manipulation to improve crop performance in extreme environments.
蔗糖非发酵-1（SNF1）相关蛋白激酶（SnRKs）得名于其真菌同源物 SNF1，后者是碳代谢的全局调节剂。植物家族已经蓬勃发展，包括 38 个成员，可分为三个亚家族：SnRK1、SnRK2 和 SnRK3。现在有充分的证据表明，这种情况的发生使得植物能够以其他生物中不存在的方式将代谢和应激信号联系起来。本文综述了 SnRKs 的作用，特别是在脱落酸诱导的信号通路、耐盐性、对营养胁迫和疾病的反应以及碳代谢和产量的调节方面。SnRKs 在代谢和应激信号之间的界面中发挥着关键作用，使它们成为潜在的候选物质，可用于操纵以改善作物在极端环境下的性能。
