Abstract

The invention provides a GmBGS2 gene for regulating the soybean seed size as well as encoded protein and an applications of the GmBGS2 gene, relates to a gene for regulating the soybean seed size as well as encoded protein and an application of the gene, and provides a gene which is separated from a soybean and used for controlling the seed size, encoded protein of the gene and an application of the protein in soybean seed size increase. The nucleotide sequence of the gen is represented as SEQ ID NO: 1 and the amino acid sequence of the encoded protein is represented as SEQ ID NO: 2. The GmBGS2 gene is transferred to the soybean, beanpod of plant with GmBGS2 gene overexpression is remarkably larger than wild beanpod; and the GmBGS2 gene is used for enlarging seeds and increasing hundred-grain weight.

Description

technical field [0001] The invention relates to a gene regulating soybean seed size, its encoded protein and its application. Background technique [0002] The size of seeds varies widely among different species of plants, and even there are significant differences in the size of seeds among different varieties of the same species. However, the final size of the seeds of a given plant variety is largely consistent, suggesting precise genetic regulation of plant seed growth and development. 100-seed weight is one of the three direct components of soybean yield, which is easily affected by the environment, and the accuracy of phenotype selection is not high. 100-seed weight has the greatest effect on the improvement of soybean yield selection genotypes, and is an important breeding goal in crop breeding. Among the existing soybean germplasm resources, the 100-seed weight varies from 15 grams to 30 grams, and there is huge genetic variation. Among soybean yield components, s...
