Figure 2From: Genome-wide identification and characterization of the bHLH gene family in tomato The bHLH domain is highly conserved across all SlbHLH proteins. The overall height of each stack represents the conservation of the sequence at that position. The asterisk indicates the position of the 19 conserved amino acids previously identified by Atchley et al. [5], and capital letters indicate over 50% conservation of amino acids among the 159 SlbHLH domains.Back to article page
