Phylogeny of Saccharomyces MALT genes.

ML phylogenetic tree of MALT genes described in S. cerevisiae, S. eubayanus, and lager-brewing hybrids. The scale bar equals the number of nucleotide substitutions per site. Black “*” indicate genes characterized as encoding proteins capable of transporting maltotriose. Gray “*” indicates genes encoding transporters whose ability to transport maltotriose is ambiguous.
