Expression profiles of CeTIP genes. a Tissue-specific expression profiles of CeTIP genes. DAS40, DAS80, and DAS120 represent tubers of 40, 80 and 120 DAS. Color scale represents FKPM normalized log2 transformed counts where blue and red indicate low and high expression, respectively. b Expression profiles of CeTIP1;1 and − 2;1 during leaf development. c Diurnal fluctuation expression patterns of CeTIP1;1 and − 2;1 in mature leaf. d Expression profiles of CeTIP1;1 and − 2;1 during tuber development. For qRT-PCR analysis, CeUCE2 and CeTIP41 were used as two reference genes. Bars and error bars indicate the mean ± SD (n = 3) and uppercase letters indicate difference significance tested following Duncan’s one-way multiple-range post hoc ANOVA (P < 0.01).
