摘 要: 植物种子中含有大量热稳定蛋白,这类蛋白质包含了LEA蛋白、蛋白酶抑制剂、甜蛋白和热激蛋白等重要的蛋白组分。热稳定蛋白的结构和功能研究揭示了这些蛋白成分与种子胁迫耐性密切相关。对种子热稳定蛋白的深入研究将进一步揭示这些蛋白在种子发育过程和抵御环境胁迫的作用机理,其应用研究对改良作物品质、提高种子和植物体对逆境胁迫的耐性及相关食品加工业具有重要意义。现综述与种子热稳定蛋白的类型和相关机理及应用研究进展。 Seed accumulated abound of heat-stable proteins in processes of development and desiccation. These heat-stable proteins included LEA protein, protease inhibitor, sweet protein and heat-shock proteins. Studies of Heat-stable proteins would help understanding the role of these proteins in seed development and stress resistance. To illustrate the regulation mechanisms of these proteins would provide improvement in seed quality promotion, plant stress resistance research and food industry. This paper reviewed the progress in research on seed heat-stable proteins and resent application approaches.
