Figure 2

The exon-intron structure of the genes and conserved protein motifs of kiwifruit R2R3-MYB transcription factors. The NJ evolutionary tree (A) was created with 1000 bootstraps based on the full-length sequences of the R2R3-AcMYBs. Exon-intron structure (B) analyses of R2R3-AcMYB genes were carried out with GSDS, and conserved protein motifs (C) were identified by MEME. Lengths of exons, introns and motifs were exhibited proportionally. Grey lines represent the nonconserved sequences, and each motif is indicated by a colored box numbered at the bottom.
