Fig. 2From: Identification of GROWTH-REGULATING FACTOR transcription factors in lettuce (Lactuca sativa) genome and functional analysis of LsaGRF5 in leaf size regulationGene structures and motif composition of LsaGRFs. A The gene structures of LsaGRFs. B The motif composition of LsaGRF proteins with MEME. Twenty motifs are represented by different colored boxes. The same color rectangle in different proteins referred to the same motif. The sizes of motifs are proportional to their sequence lengths. The order of LsaGRF genes were based on the phylogenetic tree shown on the left of the figures. The size scales of gene and protein length were indicated at the bottomBack to article page
