Due to climatic changes, rice crop is affected by moisture deficit stress and pathogens. Tissue water limitation besides reducing growth rates, also renders the crop susceptible to the infection by pv. () that causes bacterial leaf blight. Independently, both drought adaptation and resistance have been extensively studied. Though the cross-talk between drought and stress responses have been explored from individual stress studies, examining the combinatorial stress response is limited in rice. Recently published combined stress studies showed that under the combined stress, maintenance of carbon assimilation is hindered and such response is regulated by overlapping cellular mechanisms that are different from either of the individual stresses. Several receptors, MAP kinases, transcription factors, and ribosomal proteins, are predicted for playing a role in cellular homeostasis and protects cells from combined stress effects. Here we provide a critical analysis of these aspects using information from the recently published combined stress literature. This review is useful for researchers to comprehend combinatorial stress response of rice plants to drought and .
由于气候变化，水稻作物受到水分亏缺胁迫和病原体的影响。组织水分限制除了降低生长速率外，还使作物易受引起白叶枯病的 pv. （） 的感染。独立地，干旱适应性和抗性都已得到广泛研究。尽管从个体胁迫研究中探索了干旱和胁迫反应之间的相互作用，但在水稻中研究组合胁迫反应的情况有限。最近发表的组合胁迫研究表明，在组合胁迫下，碳同化的维持受到阻碍，这种反应由与任何一种个体胁迫不同的重叠细胞机制调节。预测几种受体、丝裂原活化蛋白激酶、转录因子和核糖体蛋白在细胞稳态中起作用，并保护细胞免受组合胁迫的影响。在这里，我们利用最近发表的组合胁迫文献中的信息对这些方面进行批判性分析。这篇综述有助于研究人员理解水稻植株对干旱和 的组合胁迫反应。
