Fig. 5From: Genome-wide characterization of the bHLH gene family in Gynostemma pentaphyllum reveals its potential role in the regulation of gypenoside biosynthesisPromoter cis-elements analysis of the nine gypenoside-related GpbHLH genes. A The identified cis-acting elements were divided into three functional groups and represented by red, green and blue shades of colors. The numbers indicate the quantity of corresponding cis-acting elements in each GpbHLH gene promoter region. Distribution of cis-acting elements with different categories within each group of cis-acting elements with different specific functions, including light signal (B), hormone response (C), and stress response (D)Back to article page
