The term ‘proteomics’ refers to a high-throughput technology and methodology to analyze protein profile of any organism. The complete set of proteins (proteome) of a cell is quite complex apart from being dynamic. Furthermore, environmental conditions greatly influence the accumulation of many proteins and thus dissecting the dynamics of proteome in response to any external stimuli is crucial for understanding the plant response to different environmental cues. Cold or freezing stress is a severe abiotic stress that not only reduces crop yield but also restricts the geographical distribution of many plant species on earth. The ability of the plants to adapt to various environmental stresses determines their survival and understanding this ‘ability’ is crucial for developing stress tolerant plants for improving agricultural yield. Proteomics provides an important platform to understand the molecular mechanisms lying behind cold tolerance in different plants. Here we have reviewed the current proteomics studies in plant response to cold stress with specific emphasis to cold stress response in plants at organ and organelle levels.

蛋白质组学：解密耐寒性的工具

术语“蛋白质组学”是指用于分析任何生物的蛋白质谱的高通量技术和方法。细胞的完整蛋白质（蛋白质组）除了具有动态性外，还非常复杂。此外，环境条件极大地影响了许多蛋白质的积累，因此剖析蛋白质组响应任何外部刺激的动力学对于理解植物对不同环境线索的反应至关重要。寒冷或冰冻胁迫是一种严重的非生物胁迫，不仅降低作物产量，而且限制了地球上许多植物物种的地理分布。植物适应各种环境胁迫的能力决定了它们的生存能力，了解这种“能力”对于开发耐胁迫植物以提高农业产量至关重要。蛋白质组学为了解不同植物的耐寒性背后的分子机制提供了重要平台。在这里，我们回顾了当前植物对冷胁迫的响应的蛋白质组学研究，特别着重于器官和细胞器水平的植物对冷胁迫的响应。
