Identification of the species Parastagonospora dactylidis on poaceous plants in Iran

The purpose of this study was to identify new species of Parastagonospora in association with poaceous plants in Iran. Symptomatic leaves and ears were collected from different poaceous species in the field from provinces including Fars, Khuzestan and Kohgiluyeh and Boyerahmad. In the present research, 12 isolates based on morphological characteristics and sequencing of LSU and ITS-rDNA regions were recognized as P. dactylidis on Phalaris arundinacea (fiveisolates), Bromus hordeaceus (three isolates) and Aegilops tauschii (four isolates). The species of P. dactylidis is reported from Iran for the first time and also all of the identified hosts are new host to the world.
