Gene expression of six FtEXPA genes in the BTB and STB at 13 DAP and 19 DAP and the expression patterns of five FtEXPA genes from 13 DAP and 19 DAP of the STB with IAA treatment. a The expression patterns of six FtEXPA genes in BTB and STB at 13 DAP and 19 DAP were examined using a qRT-PCR assay. Three biological replicates were performed, and three technical replicates were performed for each biological replicate. Error bars were obtained from nine measurements. Asterisk above the bars indicate significant differences (*P < 0.05; **P < 0.01) between the BTB and STB fruits. The results were visualized using GraphPad Prism 7.04. b The expression patterns of five FtEXPA genes in STB at 13 DAP and 19 DAP with IAA treatment were examined using a qRT-PCR assay.
