气候变化预计将增加非生物胁迫组合的频率和强度，这些组合对植物产生负面影响，并对作物产量和粮食供应构成严重威胁。植物通过激活特定的生理和分子反应以及调节不同的代谢途径来响应逆境组合，以减轻逆境组合对植物生长、发育和繁殖的负面影响。植物合成广泛的代谢物，调节植物生长发育的许多方面，以及植物对胁迫的反应。虽然在不同的植物物种中对单个非生物胁迫的代谢反应进行了广泛的研究，但最近的努力是为了了解当不同的非生物因素组合时发生的代谢反应。本文综述了不同植物在逆境组合下代谢组学变化的最新研究进展，并提出了发展逆境组合适应性作物的新途径--以代谢产物为育种目标。
Climate change is predicted to increase the frequency and intensity of abiotic stress combinations that negatively impact plants and pose a serious threat to crop yield and food supply. Plants respond to episodes of stress combination by activating specific physiological and molecular responses, as well as by adjusting different metabolic pathways, to mitigate the negative effects of the stress combination on plant growth, development, and reproduction. Plants synthesize a wide range of metabolites that regulate many aspects of plant growth and development, as well as plant responses to stress. Although metabolic responses to individual abiotic stresses have been studied extensively in different plant species, recent efforts have been directed at understanding metabolic responses that occur when different abiotic factors are combined. In this review we examine recent studies of metabolomic changes under stress combination in different plants and suggest new avenues for the development of stress combination-resilient crops based on metabolites as breeding targets.
