تعداد 108 جدایه قارچ Fusarium verticillioided عامل بیماری پوسیدگی فوزاریومی بلال ذرت که از نمونه های به دست آمده از مناطق مختلف جغرافیایی و ذرت خیر ایران در سال 1384 جداسازی شده بودند به همراه دو جدایه استاندارد این قارچ از آفریقای جنوبی با استفاده از نشانگرهای AFLP ارزیابی شدند. پس از استخراج DNA جدایه ها، از آنزیم های برشی EcoRI و MseI برای برش استفاده شد و قطعات برش یافته به آداپتورهای دو رش...
The effect of fludioxonil + metalaxyl-M on the mycelial morphology, sporulation and fumonisin B 1 production by Fusarium verticillioides 103 F was evaluated. Scanning electron microscopy analysis showed that the fungicide caused inhibition of hyphal growth and defects on hyphae morphology such as cell wall disruption, withered hyphae, and excessive septation. In addition, extracellular material...
Fusarium verticillioides can be transmitted via seeds and cause systemic infection in maize (Zea mays L.); its mycotoxin has harmful effects on animal and human health. We combined QTL mapping in recombinant inbred line (RIL) populations with a genome-wide association study (GWAS) of 217 diverse maize lines using 224,152 single nucleotide polymorphisms (SNPs) under controlled conditions to dete...
Maize is by quantity the most important C4 cereal crop; however, future climate changes are expected to increase maize susceptibility to mycotoxigenic fungal pathogens and reduce productivity. While rising atmospheric [CO2 ] is a driving force behind the warmer temperatures and drought, which aggravate fungal disease and mycotoxin accumulation, our understanding of how elevated [CO2 ] will effe...
The objective of this study was to identify Fusarium species in the Gibberella fujikuroi species complex from rice, sugarcane and maize as most of the Fusarium species in the species complex are found on the three crops. Isolates used were collected from the field and obtained from culture collection. The Fusarium isolates were initially sorted based on morphology and identifications confirmed ...
Agaric is a dual-purpose fungus for medicine and food, which considered healthcare product. However, in cultivation production, agaric contaminated by variety of molds, resulting decline quality yield. Fusarium, as one the poisonous filamentous fungi, seriously threatens healthy development industry even affects human health. Therefore, it necessary to establish timely accurate identification r...
Fumonisin mycotoxins are commonly found on maize and pose a health risk to humans and domesticated animals. Visible sorting of grain has been suggested as a simple technique that can be used to reduce exposure to fumonisins. We collected maize samples in 2003 from different farms in the Kaduna state of Nigeria (Northern Guinea Savanna agroecological zone) that had been sorted by farmers as eith...
Oxylipins are fatty acid-derived signaling compounds produced by all eukaryotes so far investigated; in mycotoxigenic fungi, they modulate toxin production and interactions with the host plants. Among the many enzymes responsible for oxylipin generation, Linoleate Diol Synthase 1 (LDS1) produces mainly 8-hydroperoxyoctadecenoic acid and subsequently different di-hydroxyoctadecenoic acids. In th...
