Fig. 2.

Phylogenetic relationship, gene-structure analysis, and motif distributions of S. italica GRAS genes. A Phylogenetic tree was constructed by the NJ method with 1000 replicates on each node. B Exons and introns are indicated by rectangles and gray lines, respectively. These numbers are generated based on the “phase” of the annotated file, which is about the different phases of CDS in the gene. Meanwhile, “phase” is defined as “0”, “1”, and “2”. C Amino acid motifs in the S. italica GRAS proteins (1–10) are represented by colored boxes. The black lines indicate relative protein lengths
