HIGHLIGHTS • Molecular analysis of aurofusarin biosynthesis in F. culmorum. Mycelial pigmentation depending on gene expression and accumulation. Pigmentation variations growth phase.
in this thesis, a new optically active poly(amide-imide) (pai) was synthesized by the indirect polycondensation reaction of the l-phenylalanine based diacid chloride and 4,4?-diaminodiphenylether in the presence of triethylamine in n-methyl-2-pyrrolidone. the formation of pai was confirmed by ftir, 1h nmr and elemental analysis. in next step, the surface of titanium dioxide (tio2) nanoparticles...
the main purpose of this study was to investigate any relationship between high school efl teachers metaphorical understandings of their role in class and their self-efficacy beliefs. teachers metaphors were elicited through two different prompts: one picturing what they believed a language teacher should be like in class, and the other demonstrating what they are actually like in class; such...
قارچ fusarium culmorum عامل بیماری بلایت فوزاریومی سنبلة گندم، قادر به تولید داکسی نیوالنول، نیوالنول و مشتقات استیلی آنها است. بررسی حاضر به منظور ردیابی ژن tri13 با استفاده از جفت آغازگرهای tri13donr/tri13f و tri13r/tri13nivf جهت تعیین پتانسیل جدایه های قارچ f. culmorum استان آذربایجان غربی در تولید داکسی نیوالنول و نیوالنول صورت پذیرفته است. بدین منظور از مزارع گندم ارومیه، خوی، میاندواب، ما...
the aim of this study was to identify the problems of translating markedness structures from english to persian in order to look closely at what possible difficulties translators may face. it also seeks to probe the strategies applied accordingly by iranian translators in translating them. from three translation of blindness novel, the sentences with marked structures were elicited and also the...
Fusarium genus is a wide host phytopathogen causing significant losses in multiple crops, including hops. There limited information on the sustainable management of spp. hop fields. Trichoderma an endophytic fungus used agriculture as biological control agent (BCA) and plant growth promoter. It has been to antagonize other crops. The objective current study was identify indigenous field isolate...
OBJECTIVE To compare the minimum inhibitory concentration (MIC) of cephapirin and ceftiofur with MICs of their active metabolites (desacetylcephapirin and desfuroylceftiofur) for selected mastitis pathogens. SAMPLE 488 mastitis pathogen isolates from clinically and subclinically affected cows in commercial dairy herds in Wisconsin. PROCEDURES Agar dilution was used to determine MICs for Sta...
This study investigates the potential of Pythium oligandrum (strains M1 and 00X48) as a biocontrol agent in suppressing growth Fusarium culmorum production mycotoxins during malting naturally contaminated barley (Hordeum vulgare). The effects on F. culmorum-infected malt (BM) were evaluated through real-time PCR its impact mycotoxin was determined by quantitative analysis deoxynivalenol (DON) d...
Different species of Trichoderma especially T. harzianum (Th2 biotype in Europe and Th4 in America) considered as causal agent of green mould disease on button mushroom (Agaricus bisporus) casing beds. In this study, 100 fungal isolates were collected and purified from different mushroom growing units in Tehran province and Urmia (NW Iran). Totally, 60 isolates of T. harzianum, 27 isolates of T...
a total of ten isolates of fungi with rhizoctonia-like mycelia were obtained from infected roots and stems of pistachio pistacia vera grown in a commercial nursery in rafsanjan, iran, during the autumn of 2011. the infected seedlings showed symptoms of chlorosis that later turned to necrosis. all of the isolates were identified as binucleate rhizoctonia on the basis of hyphal characteristics an...
