Phylogenetic relationship between candidate GrFH and AtFH, ZmFH, MtFH, and OsFH gene families. GrFH were classified into 7 groups (A, B, C, D, E, F, and G), each marked by different colors and shapes. The candidate gene GrFH was labeled by the red star. Whereas AtFH was labeled as round blue, ZmFH was labeled as violet color square, MtFH was labeled orange triangular, and OsFH was labeled as green triangular
