Fig. 3From: Genome-wide characterization of the bHLH gene family in Gynostemma pentaphyllum reveals its potential role in the regulation of gypenoside biosynthesisDistribution and collinearity analysis of GpbHLH genes. A Chromosomal locations and the intra-and inter-species collinear analysis of bHLH genes. The red lines inside the circle indicate segmentally duplicated GpbHLH gene pairs, while the tandem duplication gene pairs are labeled in red. B Inter-species collinear analysis of bHLH genes among G. pentaphyllum, A. thaliana, and C. sativus. Gray lines represent all collinear blocks, whereas syntenic bHLH gene pairs are highlighted as red linesBack to article page
