Line Plot from Scientific Research

Phylogenetic tree based on the concatenated protein sequence alignment of 1,612 1:1 orthologs. The tree was rooted by including 23 strains from other Saccharomyces species (not presented in the figure). The symbols on the right recall the ecological origin, ploidy and zygosity of all isolates, as described in a . The presence of aneuploid chromosomes is labeled by an asterisk with varying gray levels discriminating between several cases relative to the 1,011 genome survey 31 black, previously detected; dark gray, not previously detected; middle gray, previously absent and newly gained; light gray, previously present but newly lost.
