Expression profiles of FtPLATZ genes in different tissues and different grain developmental stages of Tartary buckwheat and correlation analysis of the expression patterns of FtPLATZ genes. a. Expression profiles of 14 FtPLATZ genes in the root (R), stem (S), leaf (L), flower (F), and grain (G-S1, initial formation stage; G-S2, green grain stage; G-S3, discoloration stage; G-S4, initial maturity stage) of Tartary buckwheat. Error bars are obtained from three biological replicates. Lowercase letters above the bars represent significant differences between different treatments, as determined by Duncan’s multiple range test (p < 0.05). b. Pearson’s correlation of expression patterns among FtPLATZ genes. Red and blue represent positive and negative correlations, respectively. * and ** indicate significance at the levels of 0.05 and 0.01, respectively
