Abstract

During an investigation on endophytic fungi of grasses of the tribe Triticeae (subtribe Triticinae) in the west and northwestern provinces of Iran, two species, viz. Sarocladium terricola and Selenophoma linicola, and one genus, Septoriella (S. allojunci), were newly identified for the funga of Iran using morphological traits and sequences of the internal transcribed spacer regions 1 and 2 including the intervening 5.8S nuclear ribosomal DNA (ITS). Selenophoma linicola and Septoriella allojunci, members of the class Dothideomycetes, were isolated from stem of Aegilops cylindrica and leaf of A. cylindrica in W. Azerbaijan and Lorestan provinces, respectively. Sarocladium terricola, belonging to the Sordariomycetes, was isolated from leaf of Triticum aestivum in Kermanshah province. All identified species are described and illustrated herewith, and compared with closely related species. Aegilops cylindrica and T. aestivum are reported as new hosts (matrix nova) for these fungi.

Abstract [Persian]

طی بررسی قارچ‌های اندوفیت گیاهان علفی قبیله Triticeae (زیرقبیله Triticinae) در استان‌های غرب و شمال‌غرب ایران، دو گونه جدید Sarocladium terricola و Selenophoma linicola و یک جنس جدید Septoriella (S. allojunci)، براساس ویژگی‌های ریخت‌شناختی و توالی‌یابی ناحیه ITS از DNA ریبوزومی، برای قارچ‌های ایران شناسایی شدند. گونه‌های Selenophoma linicola و Septoriella allojunci، از اعضای رده Dothideomycetes، از ساقه Aegilops cylindrica و برگ A. cylindrica به ترتیب در استان‌های آذربایجان‌غربی و لرستان جداسازی شدند. همچنین، گونه Sarocladium terricola متعلق به رده Sordariomycetes، از برگ Triticum aestivum در استان کرمانشاه جداسازی شد. در این مقاله، تصاویر و توصیف‌های تمامی گونه‌های شناسایی شده ارایه و با گونه‌های نزدیک مقایسه شده است. گونه‌های گیاهی A. cylindrica و T. aestivum نیز به عنوان میزبان‌های جدید برای این قارچ‌ها گزارش می‌شوند.
