Simultaneous occurrence of drought and heat stress will have significant negative impact on rice yield, especially under upland conditions. The projected increase in global temperatures and reduced precipitation will increase the frequency of occurrence and intensity of these stresses, threatening rice production. Despite recognizing the importance of combined stress in rice, the knowledge generated in this area is very limited. Though complex, understanding combined stress tolerance of rice under water saving cultivation is more critical towards development of climate resilient rice cultivars. Here, we summarized the effects of combined stress on rice physiology with more emphasis on reproductive stage. Omics responses, phenotyping and physiology challenges and potential strategies for improving combined stress tolerance in rice are also discussed.

同时发生的干旱和高温胁迫将对水稻产量产生重大不利影响，特别是在旱地条件下。预计全球温度升高和降水减少将增加这些压力的发生频率和强度，从而威胁稻米生产。尽管认识到稻米综合胁迫的重要性，但在这一领域产生的知识非常有限。尽管很复杂，但了解节水栽培下水稻的综合胁迫耐受性对发展具有气候适应力的水稻品种更为关键。在这里，我们总结了综合胁迫对水稻生理的影响，其中更着重于生育期。Omics的回应，
