The α-Specific Cell Identity Factor Sxi1α Is Not Required for Virulence of Cryptococcus neoformans

Abstract
Cryptococcus neoformans is a human fungal pathogen that has two mating types ( a and α). Experiments have shown that in some backgrounds α strains are more virulent than a strains. Our studies reveal that the only known α-specific factor, SXI1 α, is not necessary for virulence.
