New hemyascomycete phylome: Blastobotrys (Arxula) adeninivorans, a yeast of biotechnological interest.

 Arxula adeninivorans (Blastobotrys adeninivorans) is a dimorphic yeast with unusual characteristics that make it of great biotechnological interest. It is not only a source of many enzymes with interesting properties such as glucoamylase, tannase, lipasses and phosphatases, but it is also a useful yeast for the heterologous expression of proteins. In addition, this yeast is thermotolerant, xerotolerant and osmotolerant, which makes it a great model to study such phenotypic adaptations. In the context of the sequencing effort of this genome, we reconstructed the phylome for this species. This served to resolve the phylogenetic relationships with other sequenced yeasts but also to detect patterns of gene family expansions, which unveiled past multiple rounds of segmental duplications of tandem gene arrays, a novel mechanism not yet described in yeasts.

Arxula's genome and its phylome (phylome_178) are described in the following article: Kunze et. al. (2014) The complete genome of Blastobotrys (Arxula) adeninivorans LS3 - a yeast of biotechnological interest. Biotechnology for Biofuels 7:66
