Fig. 3From: Genome-wide identification and expression analysis of the R2R3-MYB gene family in tobacco (Nicotiana tabacum L.)Gene structure and evolution of R2R3-MYB family in Nicotiana tabacum. A Phylogenetic relationships of NtR2R3-MYBs. Different subgroups were marked with different colors. B Intron-exon structure of NtR2R3-MYBs. Green boxes: exons; Yellow boxes: UTR; spaces between the boxes: introns. The scale bar of bottom demonstrates the length of exons and intronsBack to article page
