Fig. 7From: Systematic identification and expression analysis of bHLH gene family reveal their relevance to abiotic stress response and anthocyanin biosynthesis in sweetpotatoThe relative expression levels of 11 IbbHLHs between flesh and skin tissues of three sweetpotato cultivars were detected by qRT-PCR. The Y-axis depicts the change in the relative expression compared to the flesh of XuShu18 (data normalized to 1). The bars represent the average of the three biological replicates ± SE. The three-fold threshold between flesh and skin tissues is represented by an asteriskBack to article page
