COTTON GHTCP4 GENE AND APPLICATION THEREOF IN MODIFYING LENGTH OF COTTON FIBER

摘要

A cotton GhTCP4 gene and an application thereof in modifying the length of a cotton fiber. The cotton GhTCP4 gene is isolated, cloned and subjected to functional identification, and an expression level of the GhTCP4 gene is regulated by molecular biology and transgenic technology, so as to make adjustment to plant growth and development, thereby obtaining a transgenic cotton having significantly longer fibers. The function and use of a GhTCP4 transcriptional factor-like protein in cotton have a positive effect on promoting the elongation of fibroblasts and improving the length and quality of cotton fibers, and thus have a broad application prospect.
