GhWOX13 subfamily gene transcription is induced by gibberellic acid (GA), brassinosteroid (BR), and auxin treatments. a Identification of putative auxin response elements (AuxREs) in the promoter regions of the four GhWOX13 gene family members. b GA-induced transcription in the three GhWOX13 genes with AuxREs in their promoter regions. The promoter of GhWOX13B does not contain an AuxRE. (c) Identification of E-box elements in the promoter regions of GhWOX13a_At/13a_Dt/13b_At/13b_Dt. d Transcription of the four hWOX13 family genes after BR treatment for 6 h, 24 h, and 5 d. e Identification of putative auxin response TGA elements in the promoter regions of the GhWOX13b_At/13b_Dt genes. f Transcription of the four GhWOX13 family genes after treatment with NAA for 12, 24, and 48 h. GhWOX13b_At and GhWOX13b_Dt have putative TGA elements in their promoter regions. Gene expression data were obtained from qRT-PCR assays with three replicates per sample, with each replicate performed using independent materials. The relative expression levels of each gene were determined by normalizing to the expression level in the CK ovules, which was set to 1.0. Statistical significance was determined using one-way analysis of variance combined with Tukey’s test. *, P < 0.05; **, P < 0.01; ***, P < 0.001
