作为最重要的农作物之一，水稻为世界上一半以上的人口提供了主要的食物。但其生产受到诸多环境因素的限制，其中花期高温胁迫频繁发生，降低了其小穗育性。为了探究水稻耐高温的机制，我们对高温抗性品种和敏感品种的花药进行了蛋白质组学比较分析。在相同的HS处理下，抗性品种的小穗育性明显高于敏感品种。蛋白质组学数据显示，HS导致敏感品种核糖体蛋白降解，而抗性品种核糖体蛋白降解不明显，这可能导致蛋白质生物合成机制受损。相比之下，HS诱导抗性品种的sHSP、β-扩张蛋白和脂质转移蛋白含量增加，这可能是抗性品种耐受HS的原因之一。研究结果为水稻HS响应机制的研究提供了新的思路。
As one of the most important crops, rice provides the major food for more than half of the world population. However, its production is limited by many environmental factors, among which high temperature stress (HS) frequently occurs during anthesis and reduces its spikelet fertility. To explore the mechanism of HS tolerance in rice, we conducted a comparative proteomics analysis on the anthers between HS resistant and sensitive cultivars under different levels of high temperature. Under the same HS treatment, the resistant cultivar showed much higher spikelet fertility than the sensitive cultivar. Proteomic data showed that HS lead to the degradation of ribosomal proteins in the sensitive cultivar but not in the resistant one, which might result in the injury of protein biosynthetic machinery. In contrast, HS induced the increase of sHSP, β-expansins and lipid transfer proteins in the resistant cultivar, which might contribute to its ability to tolerate HS. The results provide some new insights into the mechanism of rice HS response.
