Fig. 1From: Basic helix-loop-helix (bHLH) gene family in rye (Secale cereale L.): genome-wide identification, phylogeny, evolutionary expansion and expression analysesUnrooted phylogenetic tree showing relationships among bHLH proteins of S. cereale and Arabidopsis. The phylogenetic tree was derived using the neighbor-joining method in MEGA7.0. The tree shows the 21 phylogenetic subfamilies, which are denoted in red font. bHLH proteins from Arabidopsis are denoted by the prefix ‘At’Back to article page
