蛋白质含量的高低是衡量稻米营养价值的主要指标之一,因此提高蛋白质含量是稻米营养品质育种的重要目标。本文阐述了水稻蛋白质种类、氨基酸组成及其营养价值,并概括了水稻不同基因型和不同部位或组织间蛋白质含量的差异、蛋白质含量的遗传及分子机理以及种质创新的研究现状,可为水稻蛋白质含量的深入研究和高蛋白种质创新提供参考。 The level of protein content is one of the main indicators to measure the nutritional value of rice. Therefore, increasing the protein content is an important goal of rice nutritional quality breeding. In this paper, the types of proteins, the composition of amino acids and their nutritional value in rice were summarized. The differences in protein content among different genotypes and parts or tissues of rice, the genetic and molecular mechanisms of protein content, and the research status of germplasm innovation were summarized. Protein content in-depth research and high protein germplasm innovation provide a reference.
