Core regulatory components of the PHO pathway are conserved in the methylotrophic yeast Hansenula polymorpha.

ABSTRACT: To gain better understanding of the diversity and evolution of the gene regulation system in eukaryotes, the phosphate signal transduction (PHO) pathway in non-conventional yeasts has been studied in recent years. Here we characterized the PHO pathway of Hansenula polymorpha, which is genetically tractable and distantly related to Saccharomyces cerevisiae and Schizosaccharomyces pombe, in order to get more information for the diversity and evolution of the PHO pathway in yeasts. We generated several pho gene-deficient mutants based on the annotated draft genome of H. polymorpha BY4329. Except for the Hppho2-deficient mutant, these mutants exhibited the same phenotype of repressible acid phosphatase (APase) production as their S. cerevisiae counterparts. Subsequently, Hppho80 and Hppho85 mu
