Abstract

The oomycete pathogens causing white blister rusts on members of Asteridae comprise different species within the genus Pustula (Albuginales, Oomycota). During the collection of white blister rust specimens in the South Khorasan province (eastern Iran) in April 2019, a specimen collected from Takhtajaniantha pusilla (Asteraceae), was identified morphologically as Pustula junggarensis (Albuginales, Oomycota). BLAST search using the ITS nrDNA sequence data, confirmed the identification. Also, the phylogenetic analysis using cox2 sequences clustered the species in the same clade with P. junggarensis sequences from China. This is the first record of P. junggarensis in Iran. To the best of our knowledge, this is the first report of a disease caused by a causative fungal/fungal-like agent on T. pusilla in Iran.
