Pneumocystis carinii exhibits a conserved meiotic control pathway.

ABSTRACT: Pneumocystis carinii is an opportunistic fungus causing severe pneumonia in immune-compromised hosts. Recent evidence suggests that Pneumocystis exists as separate sex types, though definitive evidence is currently lacking. These studies were undertaken to determine whether Pneumocystis maintains functional meiotic control molecules, which are required for sexual life stages in eukaryotes. Using the Pneumocystis carinii Genome Project database, two partial sequences for meiotic control molecules were detected, namely, PCRan1, a presumptive meiotic control kinase, and PCMei2, a homologue to a primary activator of meiosis in Schizosaccharomyces pombe. Rapid amplification of cDNA ends was employed to obtain the full open reading frames and to further investigate the functions of these protein
