Identification of the MATa mating-type locus of <i>Cryptococcus neoformans</i> reveals a serotype A MATa strain thought to have been extinct
19 Dec 2000
Abstract excerpt
Cryptococcus neoformans is an opportunistic fungal pathogen with a defined sexual cycle involving mating between haploid MATa and MATalpha cells. Here we describe the isolation of part of the MATa mating-type locus encoding a Ste20 kinase homolog, Ste20a. We show that the STE20a gene cosegregates with the MATa mating type in genetic crosses, maps within the mating-type locus on a 1.8-Mb chromosome, and is allelic...
