[ 1 ] - Notes on some endophytic fungi isolated from Quercus brantii in Dena, Kohgiluyeh and Boyer-Ahmad province
In this study, we report some endophytic fungi isolated from twigs of Quercus brantii in Dena region of Kohgiluyeh and Boyer-Ahmad province. The twigs were sampled from trees which had basidiocarps of the invasive basidiomycetous polypore fungus Inonotus krawtzewii on their trunk. Altogether, ca. 40 pure isolates were obtained. The ITS sequences were obtained for 16 isolates, and their phylogen...
[ 2 ] - برخی از ویژگی‌های زیست‌شناسی و مرفولوژیکی Platychora ulmi، عامل لکه برگی نارون در همدان (گزارش کوتاه علمی)
طی سال‌های 1385 و 1386، علایم لکه برگی روی درختان نارون (Ulmus minor Mill.) واقع در حاشیه رودخانه‌های اطراف همدان با شدت نسبتاً زیاد مشاهده شد. به منظور جداسازی عامل بیماری قطعاتی از برگ‌های آلوده پس از ضدعفونی سطحی با هیپوکلریت سدیم 1-5/0 درصد روی محیط‌های کشت PDA (potato-dextrose agar, Merck) و MEA (malt extract agar, Merck) قرار داده شدند. مشاهده برگ‌های آلوده از طریق تهیه مقاطع عرضی با استفا...
[ 3 ] - Systematics of Aspergillus species of subgenus Nidulantes in Iran
Aspergillus subgenus Nidulantes accommodates species of industrial and medical importance. Thirty isolates morphologically assigned to subgenus Nidulantes were studied, 25 isolated from cereals in the north and northwestern provinces and the rest from other substrates in Iran. Based on morphological and molecular data (sequences of the ITS rDNA and β-tubulin), nine species were identified belon...
