Soil salinity is a major abiotic stress that limits plant growth and agriculture productivity. To cope with salt stress, plants have evolved complex salt-responsive signaling and metabolic processes at the cellular, organ, and whole-plant levels. Investigation of the physiological and molecular mechanisms underlying plant salinity tolerance will provide valuable information for effective engineering strategies. Current proteomics provides a high-throughput approach to study sophisticated molecular networks in plants. In this review, we describe a salt-responsive protein database by an integrated analysis of proteomics-based studies. The database contains 2171 salt-responsive protein identities representing 561 unique proteins. These proteins have been identified from leaves, roots, shoots, seedlings, unicells, grains, hypocotyls, radicles, and panicles from 34 plant species. The identified proteins provide invaluable information toward understanding the complex and fine-tuned plant salt-tolerance mechanisms in photosynthesis, reactive oxygen species (ROS) scavenging, ion homeostasis, osmotic modulation, signaling transduction, transcription, protein synthesis/turnover, cytoskeleton dynamics, and cross-tolerance to different stress conditions.
土壤盐度是限制植物生长和农业生产力的主要非生物胁迫因素。为了应对盐胁迫，植物在细胞、器官和整株水平上进化出了复杂的盐响应信号和代谢过程。研究植物耐盐性的生理和分子机制将为有效的工程策略提供有价值的信息。目前的蛋白质组学为研究植物中复杂的分子网络提供了一种高通量的方法。在这篇综述中，我们通过对基于蛋白质组学的研究进行综合分析，描述了一个盐响应蛋白数据库。该数据库包含 2171 种盐响应蛋白，代表 561 种独特的蛋白质。这些蛋白质已从 34 种植物的叶片、根、茎、幼苗、单细胞、谷物、下胚轴、胚根和穗中鉴定出来。鉴定出的蛋白质为理解光合作用、活性氧（ROS）清除、离子稳态、渗透调节、信号转导、转录、蛋白质合成/周转、细胞骨架动态以及对不同胁迫条件的交叉耐受等复杂而精细的植物耐盐机制提供了宝贵的信息。
