Rice proteomics has progressed at a tremendous pace since the year 2000, and that has resulted in establishing and understanding the proteomes of tissues, organs, and organelles under both normal and abnormal (adverse) environmental conditions. Established proteomes have also helped in re-annotating the rice genome and revealing the new role of previously known proteins. The progress of rice proteomics had recognized it as the corner/stepping stone for at least cereal crops. Rice proteomics remains a model system for crops as per its exemplary proteomics research. Proteomics-based discoveries in rice are likely to be translated in improving crop plants and vice versa against ever-changing environmental factors. This review comprehensively covers rice proteomics studies from August 2010 to July 2013, with major focus on rice responses to diverse abiotic (drought, salt, oxidative, temperature, nutrient, hormone, metal ions, UV radiation, and ozone) as well as various biotic stresses, especially rice-pathogen interactions. The differentially regulated proteins in response to various abiotic stresses in different tissues have also been summarized, indicating key metabolic and regulatory pathways. We envision a significant role of rice proteomics in addressing the global ground level problem of food security, to meet the demands of the human population which is expected to reach six to nine billion by 2040.
自2000年以来，水稻蛋白质组学取得了巨大进展，这使得人们能够建立并了解正常和异常（不利）环境条件下组织、器官和细胞器的蛋白质组。已建立的蛋白质组也有助于对水稻基因组进行重新注释，并揭示先前已知蛋白质的新作用。水稻蛋白质组学的进展使其成为至少谷类作物研究的核心/基石。根据其典范性的蛋白质组学研究，水稻蛋白质组学仍然是作物的一个模型系统。基于蛋白质组学在水稻中的发现很可能转化为改良作物，反之亦然，以应对不断变化的环境因素。本综述全面涵盖了2010年8月至2013年7月的水稻蛋白质组学研究，主要关注水稻对各种非生物胁迫（干旱、盐、氧化、温度、营养、激素、金属离子、紫外线辐射和臭氧）以及各种生物胁迫的反应，特别是水稻与病原体的相互作用。还总结了不同组织中对各种非生物胁迫响应的差异调节蛋白，指出了关键的代谢和调控途径。我们设想水稻蛋白质组学在解决全球粮食安全这一地面问题方面将发挥重要作用，以满足预计到2040年将达到60亿至90亿的人口需求。
