Fig. 2From: Genome-wide identification and expression analysis of the R2R3-MYB gene family in tobacco (Nicotiana tabacum L.)Gene duplication of NtR2R3-MYB genes on 24 chromosomes of tobacco genome. The segmental duplicated gene pairs are linked by different colored lines, and the tandem duplicated gene pairs of Nt04 are marked with red dashed lines. The corresponding relationships of duplicated gene are listed in Additional file 2: Table S2Back to article page
