UDP-Glucose Dehydrogenases: Identification, Expression, and Function Analyses in Upland Cotton ( Gossypium hirsutum )

UDP-glucose dehydrogenase (UGD; EC1.1.1.22) is a NAD -dependent enzyme that catalyzes the two-fold oxidation of UDP-glucose (UDP-Glc) to produce UDP-glucuronic acid and plays an important role in plant cell wall synthesis.

Description
Summary:UDP-glucose dehydrogenase (UGD; EC1.1.1.22) is a NAD -dependent enzyme that catalyzes the two-fold oxidation of UDP-glucose (UDP-Glc) to produce UDP-glucuronic acid and plays an important role in plant cell wall synthesis. A total of 42 genes from four genomes including . , . , . , and . were identified and found that the gene family has conservative evolution patterns in gene structure and protein domain. The growth of fibers can be effectively promoted after adding the UDP-Glc to the medium, and the gene expression enhanced. In addition, the transgenic lines over-expressing had longer root lengths and higher gene expression level than the wild-type plants of . These results indicated that may play important roles in cotton fiber development and has a guiding significance for dissecting fiber development mechanism.
