Fig. 4From: Systematic identification and expression analysis of bHLH gene family reveal their relevance to abiotic stress response and anthocyanin biosynthesis in sweetpotatoCollinearity analyses of bHLH genes between sweetpotato and the eight representative plant species from I. trifida and I. triloba (A), Arabidopsis and rice (B), tomato and pepper (C), cabbage and Brassica oleracea (D). The chromosomes of different plants are distinguished with differential colors. The blue lines connecting two different chromosomes indicate all the syntenic bHLH gene pairs within sweetpotato and other plant genomesBack to article page
