Inversion of the Chromosomal Region between Two Mating Type Loci Switches the Mating Type in


The mating system of Saccharomycotina has evolved from the ancestral heterothallic system as seen in Yarrowia lipolytica to homothallism as seen in Saccharomyces cerevisiae. The acquisition of silent cassettes was an important step towards homothallism. However, some Saccharomycotina species that diverged from the common ancestor before the acquisition of silent cassettes are also homothallic, including Hansenula polymorpha. We investigated the structure and functions of the mating type locus (MAT) in H. polymorpha, and found two MAT loci, MAT1 and MAT2. Although MAT1 contains both a and α information, the results suggest that it functions as MATα. MATa is represented by MAT2, which is located at a distance of 18 kb from MAT1. The functional repression of MAT1 or MAT2 was required to establish a or α mating type identity in individual cells. The chromosomal location of MAT1 and MAT2 was found to influence their transcriptional status, with only one locus maintained in an active state. An inversion of the MAT intervening region resulted in the switching of the two MAT loci and hence of mating type identity, which was required for homothallism. This chromosomal inversion-based mechanism represents a novel form of mating type switching that requires two MAT loci, of which only one is expressed.
