Leaf blotch is a globally important disease of barley crops and other grasses that is caused by at least five host‐specialized species in the fungal genusRhynchosporium. The pathogenR. commune(specialized to barley, brome‐grass and Italian ryegrass) has long been considered to reproduce only by asexual means, but there has been accumulating evidence for recombination and gene flow from population genetic studies and the detection of complementaryMAT1‐1andMAT1‐2isolates in ac. 1:1 ratio in the field. Here, it is demonstrated that 28 isolates of the closely related speciesR. agropyri(on couch‐grass) andR. secalis(on rye and triticale), collected from Europe, were also either ofMAT1‐1orMAT1‐2genotype and that the distribution of mating types did not deviate significantly from a 1:1 ratio. Evidence is then provided forMAT1‐1‐1andMAT1‐2‐1gene expression during mycelial growth for all three species. By contrast, 27 isolates of the more distantly relatedR. orthosporum(on cocksfoot) andR. lolii(on Italian and perennial ryegrasses) from Europe were exclusively of theMAT1‐1genotype, and expression of theMAT1‐1‐1gene could not be detected during mycelial growth. These data suggest that cryptic sexual cycles are more likely to exist forR. commune,R. agropyriandR. secalisthan for eitherR. orthosporumorR. lolii. A phylogenetic analysis of partialMAT1‐1idiomorph sequences resolved these five species into two distinct groups (R. commune,R. agropyriandR.secalisversusR. orthosporumandR. lolii) but provided only limited resolution within each group.
