Fig. 2

The motif, domain, and gene structure of GrFH genes. A The grouping and colors of the GrFH gene family members are based on the phylogenetic relationship. Each motif is illustrated by a specific-colored box aligned on the right side of the figure. Different colors indicate individual motifs. B The positions of the FH2 conserved domain is demonstrated in red color, whereas the entire protein sequence of respective GrFH is green colored. C For the color bar of GrFH gene structure, black lines represent introns, blue represents exons, and deep pink lines represent upstream/downstream
