چکیده

Parastagonospora species are common plant pathogens that infect wheat, barley, and a wide range of wild grasses from family poaceae. in a survey on fungal species associated with leaf spot diseases of wild grasses growing in wheat fields in kohgiluyeh boyer-ahmad and fars provinces (iran). parastagonospora isolates were recovered from necrotic lesions on leaves, ears, and stems of aegilops tauschii growing within and near wheat fields. based on morphological characterization coupled with lsu and its molecular data, the species were identified as p. poae and p. minima. this is the first report of these species on a. tauschii worldwide and the first report of these species in iran. the obtained parastagonospora species caused necrosis lesions on the ‘chamran’ cultivar of wheat in greenhouse. the presence of parastagonospora spp. on wild grass species growing within or near fields of cultivated wheat likely represents a source of emerging pathogens from these regions in the future.

Abstract

parastagonospora species are common plant pathogens that infect wheat, barley, and a wide range of wild grasses from family poaceae. in a survey on fungal species associated with leaf spot diseases of wild grasses growing in wheat fields in kohgiluyeh boyer-ahmad and fars provinces (iran). parastagonospora isolates were recovered from necrotic lesions on leaves, ears, and stems of aegilops tauschii growing within and near wheat fields. based on morphological characterization coupled with lsu and its molecular data, the species were identified as p. poae and p. minima. this is the first report of these species on a. tauschii worldwide and the first report of these species in iran. the obtained parastagonospora species caused necrosis lesions on the ‘chamran’ cultivar of wheat in greenhouse. the presence of parastagonospora spp. on wild grass species growing within or near fields of cultivated wheat likely represents a source of emerging pathogens from these regions in the future.
