The dothideomycete genera Bipolaris and Curvularia are important pathogens of grasses (Poaceae) can associate with host tissues without disease symptoms. Species both responsible for leaf spot epidemics that commonly occur on turfgrass throughout the United States transition zone southern regions. Recent species typifications DNA sequences have made a broad examination obtained from possible. I...
به منظور مطالعه گونه‌های جنس‌های Bipolaris و Curvularia همراه گیاهان ذرت، سورگوم و نیشکر طی تابستان 1390 و 1391 نمونهبرداری از اندامهای هوایی گیاهان دارای علایم لکهبرگی در مزارع مناطق مختلف کشور (استانهای مازندران، گلستان، گیلان، اردبیل، زنجان، البرز، فارس و خوزستان) به عمل آمد. شناسایی گونه‌های قارچی بر اساس خصوصیات ریخت شناختی و اطلاعات توالی حاصل از نواحی ITS از DNA ریبوزومی صورت پذیرفت....
Aerobiological sampling traditionally uses a volumetric spore trap located in a fixed position to estimate personal exposure to airborne fungi. In this study, the number and identity of fungi inhaled by human subjects (n=34), wearing Intra-nasal air samplers (INASs), was measured over 2-hour periods in an outdoor community setting, and compared to fungal counts made with a Burkard spore trap an...
FTIR and Raman spectromicroscopy were used to characterize the composition of Curvularia protuberata hyphae, and to compare a strain isolated from plants inhabiting geothermal soils with a non-geothermal isolate. Thermal IR source images of hyphae have been acquired with a 64 × 64 element focal plane array detector; single point IR spectra have been obtained with synchrotron source light. In so...
Results The data analyzed so far revealed the presence of different pollen and fungal species at both sites. The ratio between the pollen and fungal spores was 1:5. The airborne pollen grains showed quantitative and qualitative differences between the two sites. At FD site, the major pollen grains included Phoenix dactylifera (31%), grass pollen (14%), Atriplex nummularia (12%), Amaranthus viri...
