A METHOD OF UTILIZING RDL1 GENE TO PROMOTE SEED ENLARGEMENT AND COTTON FIBER ELONGATION

摘要

Use of the plant RDL1 gene or RDL1 protein in improving the properties of crop seeds and the method thereof. Specifically, a gene engineering method of utilizing the plant RDL1gene to promote seed enlargement and cotton fiber elongation. Also, the vector and the host cell comprising the RDL1 gene, and the method for preparing the transgenic plant, and obtaining the seed with improved properties using thereof are provided. The transgenic plant comprising the RDL1gene, and the hybrid progeny obtained by crossing the transgenic plants and the non-transgenic plants or other transgenic plants. The method can increase the seed size, the seed weight, the seed fiber and/or the seed fiber intensity, and is valuable for improving the crop yield and properties, and has widely application prospect.
