Identification of the species <i>Parastagonospora dactylidis</i> on poaceous plants in Iran

Abstract

The purpose of this study was to identify new species of <em>Parastagonospora</em> 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 <em>P.</em> <em>dactylidis</em> on<em> Phalaris arundinacea </em>(fiveisolates), <em>Bromus hordeaceus</em> (three isolates) and<em> Aegilops tauschii </em>(four isolates). The species of <em>P.</em> <em>dactylidis</em> is reported from Iran for the first time and also all of the identified hosts are new host to the world.
