Assessment reveals high disease incidence in Poa poophagorum plants, suggesting Alternaria chlamydosporigena's role as a pathogen.

Approximately 80% of inoculated Poa poophagorum plants exhibited wilting and mortality, confirming Alternaria chlamydosporigena's pathogenicity.
A Phylogenetic tree placed all isolates in a clade with Alternaria chlamydosporigena strain CBS 341.71, indicating strong genetic identity.
A disease incidence of about 60% was observed in surveyed grasslands in Wulan County, highlighting the impact of this fungus on natural grasslands.
The successful re-isolation of the fungus from symptomatic roots fulfills Koch's postulates, reinforcing its classification as a pathogen.

Wang et al. (2025) studied this question.
