Gene expression of Tartary buckwheat expansin genes during fruit development and the correlation between the gene expression patterns of FtEXPs during fruit development. a The expression patterns of Tartary buckwheat FtEXPs in the fruit developmental stages 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. Lowercase letter(s) above the bars indicate significant differences (α = 0.05, LSD) among fruits at different developmental stages. The results were visualized using GraphPad Prism 7.04. b The correlation of expression patterns of Tartary buckwheat expansin genes in different fruit developmental stages was visualized by TBTools v1.082. Positive number: positively correlated; negative number: negatively correlated. Red numbers indicate a significant correlation at the 0.05 level
