The destructive soilborne Fusarium species is one of the most serious challenges facing agriculture. Mycotoxins produced by spp. can induce both acute and chronic toxic effects on humans animals. Massive investments have been made in last few decades to develop an appropriate management strategy control cereals, particularly wheat, using genetic resistance other practices, with varied outcomes....
In order to determine the causal agents of Fusarium head blight, during 2015–16, wheat heads with disease symptom were collected from 10 and six main wheat production areas of Golestan and Mazandaran provinces (N Iran), respectively. A total of 431 Fusarium isolates were obtained belonging to nine Fusarium species based on their morphological characteristics. Fusarium graminearum species comple...
هدف از این مطالعه شناسایی گونههای Fusarium همراه با ریشه و بنه زعفران و ارزیابی فعالیت آنزیمهای مخرب دیواره سلولی تولید شده توسط آنها می باشد. به منظور بررسی گونههای Fusarium، طی فصل رشدی 1397 در مجموع 53 نمونه ریشه و بنه به طور تصادفی از مزارع زعفران استان خراسان جنوبی جمعآوری شد. پس از شستشو نمونهها با آب مقطر استریل و ضدعفونی سطحی با هیپوکلریت سدیم یک درصد، قطعات کوچک...
به منظور شناسایی و بررسی گونههای فوزاریوم عامل پوسیدگی خشک سیب زمینی از غدههای انبار شده در استانهای اردبیل, تهران و همدان از آذر ماه 1380 تا فروردین 1381 نمونه برداری شد. غدههای با علایم بیماری به آزمایشگاه منتقل و از بافتهای آلوده پس از ضد عفونی, کشت به عمل آمد. جدایهها بر اساس مشخصات ریختشناسی شناسایی شدند. از 208 جدایه فوزاریوم بدست آمده گونههای Fusarium acuminatum، F. culmorum، F...
In this study, twenty of the most common Fusarium species were molecularly characterized and inoculated on potato dextrose agar (PDA), rice and maize medium, where thirty three targeted mycotoxins, which might be the secondary metabolites of the identified fungal species, were detected by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Statistical analysis was performed with principa...
Fungi of the genus Fusarium infect cereal crops during the growing season and cause head blight and other diseases. Their toxic secondary metabolites (mycotoxins) contaminate grains. Several dozen toxic compounds produced by fungal pathogens have been identified to date. Type B trichothecenes-deoxynivalenol, its acetyl derivatives and nivalenol (produced mainly by F. graminearum and F. culmorum...
Fungal infection of barley and malt, particularly by the Fusarium species, is a direct cause of spontaneous overfoaming of beer, referred to as gushing. We have shown previously that small fungal proteins, hydrophobins, act as gushing-inducing factors in beer. The aim of our present study was to isolate and characterize hydrophobins from a gushing-active fungus, Fusarium graminearum (teleomorph...
The increased occurrence of Fusarium-mycotoxins in Norwegian cereals over the last decade, is thought to be caused by increased inoculum resulting from more cereal residues at the soil surface as a result of reduced tillage practices. In addition, weather conditions have increasingly promoted inoculum development and infection by Fusarium species. The objective of this work was to elucidate the...
