Characteristics of the CpSte11 gene from Cryphonectria parasitica. Schematic organization of CpSTE11 and its homologues from other fungi: Saccharomyces cerevisiae Ste11, Schizosaccharomyces pombe Byr2, Cryptococcus neoformans CnSte11, Magnaporthe grisea Mst11, Fusarium graminearum FgSte11 and Pneumocystis carinii Mekk. The sterile α motif (SAM) domain, Ras‐association (RA) domain and C‐terminal kinase domain are represented by white, black and grey boxes, respectively.
