“…Examples of well-characterized pheromone receptor genes, some of which control processes needed for virulence, have been characterized in Candida albicans (Tzung et al, 2001;Bennett et al, 2003), Cryptococcus neoformans (Chung et al, 2002), Neurospora crassa (Kim and Borkovich, 2004), Coprinus cinereus (O'Shea et al, 1998), Schizophyllum commune (Fowler et al, 1999), and Ustilago maydis (Bolker et al, 1992). In the fission yeast Schizosaccharomyces pombe, GPCRs have been also described (Tanaka et al, 1993;Kitamura and Shimoda, 1991) and receptor mutants exhibiting constitutive activity have been isolated (Ladds et al, 2005).…”
