Prediction of TF binding sites in the promoter of GhPRGL and experimental verification of the core region that affects gene expression. A Four serial 5’-deletion fragments (pGhPRGL1732, pGhPRGL1339, pGhPRGL991, and pGhPRGL638) were generated, with different colors denoting the different binding elements. On the left side of each fragment is its length. B Relative reporter activity of each promoter fragment in the dual luciferase assay. The control LUC/REN fold value was set to 1.0. Values are the mean ± SD of three biological replicates. Tukey’s HSD: ** P < 0.01
