Annotation of the S. arboricolus genome. (A) A Gbrowse_syn visualization of the inversion on chromosome VI within S. cerevisiae with respect to S. arboricolus and S. bayanus. (B) Novel and non-syntenic genes are predominantly telomeric. Each chromosome was divided in deciles and the fraction of genes predicted at each decile that we define as novel and non-syntenic is shown. (C) Gene complement differences from S. cerevisiae can be explained by S. cerevisiae specific gene loss. A Gbrowse_syn visualization, showing a gene (labeled as 2721_g) present in both S. bayanus and S. arboricolus, but not in S. cerevisiae. In the Gbrowse_syn visualizations S. bayanus genes are shown in pink, S. arboricolus genes in blue and S. cerevisiae genes in orange; S. bayanus - S. arboricolus syntenic regions are marked by blue horizontal lines; S. arboricolus - S. cerevisiae syntenic regions are marked by green horizontal lines.
