棉花纤维特异/优势表达基因的染色体定位
Chromosome Mapping Fiber Specific/Enriched Genes in Cotton
摘要
Abstract
Cotton is one of the most important economic crops in the world, and developing cotton fiber is a perfect experimental model for studying the mechanism of cell elongation, wall development and cellulose biosynthesis in plants. Up to now, many genes that expressed specifically or preferentially in developing cotton fiber have been isolated. In order to facilitate map-based cloning of these genes and make them useful in cotton fiber breeding, genetic mapping was performed to chromosome localization of these genes by experimental and Blast analysis. GhCFE and GhGLP1-250 were mapped to chromosome 6 and 19, respectively, in the [(Emian22 × 3-79) × Emian22] BC_1 population. Eleven genes were mapped corresponding chromosomes by Blast analysis. These mapped genes are involved for cotton fiber elongation and cell wall synthesis, and markers linked to these genes will be helpful in marker assisted selection for cotton fiber length and strength.关键词
