Chromosomal distribution of BvMYB genes. R2R3-MYB genes are present on all nine chromosomes in the B. vulgaris genome. Each broad vertical bar represents one chromosome drawn to scale. The black parts indicate concatenated scaffolds and grey parts mark scaffolds assigned to a chromosome without detailed position. The positions of centromeres (white dots) are roughly estimated from repeats distribution data. The chromosomal positions of the MYB genes (given in four-letter-ID) are indicated by horizontal lines. R2R3-MYB genes are given in black letters and other MYB genes are given in grey letters. The bracketed numbers below the chromosomes show the number of MYB genes on this chromosome. Eight R2R3-MYB genes could not be localised to a specific chromosome (unanchored). Vertical black lines indicate R2R3-MYB genes which are located in close proximity (sister gene pairs).
