Fig 3. Motif composition and logos of peach bHLH proteins.

A. The logos of motifs 1 and 2, which together constitute the bHLH domain in peach. The overall height of each stack represents the conservation of the sequence at that position. The capital letters indicate over 50% conservation of amino acids among the bHLH domains. The Arabic numerals under the colored capital letters indicate the width of the motif. Each color of the English letters represents a type of amino acid residue. B. The logo of motif 3, which constitutes another conserved motif, is present only in eight members of subfamily III e.
