Rhynchosporium commune (formerly known as Rhynchosporium secalis), the causal agent of scald disease on barley, is known to spread asexually by splash dispersed conidia. However, there are multiple lines of evidence for the possibility of a clandestine sexual cycle occurrence in this species including extensive genotypic diversity, equal distribution of mating type alleles across the world and ...

Rhynchosporoside, a phytotoxic compound, has been isolated from cultures of Rhynchosporium secalis, the causal agent of scald disease of barley. The toxin is a cello-bioside of 1,2-propanediol. The compound may play some role in symptom expression because it was isolated from diseased plants in concentrations similar to those that could cause symptoms in toxin-treated plants. The toxin causes l...

Abstract Various fungal species continue to be one of the most difficult challenges faced by farmers, and hence societies in whole, when it comes securing plentiful wholesome food for a rapidly growing human population. Understanding biology pathogenic fungi detail, both at population molecular levels, combined with continued emphasis on resistance breeding important crops, offers obvious susta...

leaf blotch disease of barley, caused by rhynchosporium secalis is a major disease of barley in iran. its worldwide occurrence and economic importance in barley production has motivated studies on the population genetic structure of this pathogen. random amplified polymorphic dna (rapd) method was utilized to investigate the genetic diversity of populations of r. secalis isolated from barley le...
