Expression profiles of SlbZIP1 gene in different tissues of WT and ripening mutant fruits. a Expression patterns of SlbZIP1 in different tissues of WT plants. The relative expression levels were normalized to 1 in roots. b Expression patterns of SlbZIP1 between WT and ripening mutant fruits. Total RNA from the Nr (never ripe) and rin (ripening inhibitor) fruits from IMG to B + 7 equivalent stages with WT was subjected to qRT-PCR. The relative expression levels were normalized to 1 in IMG fruits of AC. Ro, roots; St, stems; Yl, young leaves; Ml, mature leaves; Sl, senescent leaves; Fl, flowers; Se, sepals; IMG, immature green; MG, mature green; B, breaker; B + 4, 4 d after breaker stage; B + 7, 7 d after breaker stage. Bars represent the mean of three biological replicates ± SE
