小麦是西南地区的主要粮食作物之一。由于西南特殊的生态地理环境和当下品质育种的局限性，导致西南小麦加工品质较差，这正严重影响西南麦区小麦生产。小麦种子储藏蛋白主要包括谷蛋白和醇溶蛋白，它们决定小麦独特的加工品质，且是人类日常摄取所需蛋白营养的主要来源之一。本项目在前期研究工作基础上，拟系统研究品种与环境互作、栽培措施、植物生长调节剂对植物内源激素含量及其信号转导的影响，以及这些因素如何影响种子储藏蛋白表达、积累和组装。在此基础上分析西南小麦加工品质形成的分子机理，建立西南麦区小麦加工品质评价参数，为通过品种育种和栽培措施改善西南小麦加工品质提供理论依据。

The poor processing quality of wheat in Southwest China is critically determined by the special ecological and geographical environment of Southwest China and the limitations in the progress of wheat breeding to date, even though wheat is one of the major crops in Southwest China. The unique properties of wheat flour primarily depend on seed storage proteins, one of the most important sources of protein for human being, which mainly consist of glutenins and gliadins. This project aims to systematically investigate (1) the effect of interactions between wheat cultivars and environment (i.e. Gene x Environment, G x E), cultivation measures and plant growth regulators on endogenous phytohormone levels and signal transduction, and (2) how they, including G x E, cultivation measures, plant growth regulators and endogenous phytohormones, affecting the gene expression, accumulation and assembly of wheat seed storage proteins during the development of seeds, and (3) their general effect on wheat processing parameters, and noodle, steamed bread-making quality. Based on these findings, we can clarify the molecular mechanisms of the formation of wheat processing quality in Southwest China, optimize the wheat processing parameters in Southwest China, and provide foundation for further improvement of wheat processing quality by breeding and cultivation.
