The two important Fusarium ear rots of corn, Gibberella ear rot (Fusarium graminearum, formally F. moniliforme and allied species) and Fusarium ear rot (F. verticillioides and allied species) grow under different environmental conditions. F. graminearum grows well only between 26 and 28 degrees C and requires rain both at silking and during disease progression. F. verticillioides grows well at ...
We sequenced and annotated the genome of the filamentous fungus Fusarium graminearum, a major pathogen of cultivated cereals. Very few repetitive sequences were detected, and the process of repeat-induced point mutation, in which duplicated sequences are subject to extensive mutation, may partially account for the reduced repeat content and apparent low number of paralogous (ancestrally duplica...
Fusarium graminearum causes Fusarium head blight (FHB), a devastating disease that leads to extensive yield and quality loss of wheat and barley. Bacteria isolated from wheat kernels and plant anthers were screened for antagonistic activity against F. graminearum. Based on its in vitro effectiveness, strain SG6 was selected for characterization and identified as Bacillus subtilis. B. subtilis S...
The fungal pathogen Fusarium graminearum (telomorph Gibberella zeae) is the causal agent of several destructive crop diseases. Investigating subcellular localizations of F. graminearum proteins can provide insight into pathogenic mechanisms underlying F. graminearum-host interactions. In this paper, we design a novel balanced ensemble classifier based on support vector machines (SVMs) to predic...
در تحقیق حاضر، بهینه‌سازی و مدل‌سازی فعالیت بازدارندگی رشد میسلیومی و سمیت تدخینی اسانس آویشن باغی با استفاده از روش سطح پاسخ، به‌ترتیب روی دو قارچ مهم بیماری‌زای Fusarium graminearum و Botrytis cinerea و سوسک زیان‌آور غلات (Rhyzopertha dominica F.) مورد بررسی قرار گرفت. همچنین اجزای شیمیایی اسانس مذکور با استفاده از دستگاه گاز کروماتوگرافی-طیف‌سنج جرمی بررسی شد و کارواکرول (99/27 درصد)، تیمول ...
Fusarium graminearum is a ubiquitous plant pathogen, which is able to produce several bioactive secondary metabolites. Recently, the cyclic lipopeptide fusaristatin A was isolated from this species and the biosynthetic gene cluster identified. Fusaristatin A consists of a C24 reduced polyketide and the three amino acids dehydroalanine, β-aminoisobutyric acid and glutamine and is biosynthesized ...
The effects of osthol, a plant coumarin, on morphology, sugar uptake and cell wall components of Fusarium graminearum were examined in vitro by electron microscopy,(14)C-labelling and enzyme activity detection. The results revealed that osthol could inhibit the hypha growth of F. graminearum by decreasing hyphal absorption to reducing sugar. After treatment with 100 microg.mL(-1) osthol for 24 ...
Fusarium graminearum is the primary causal pathogen of Fusarium head blight of wheat and barley. To accelerate genomic analysis of F. graminearum, we developed a bacterial artificial chromosome (BAC)-based physical map and integrated it with the genome sequence and genetic map. One BAC library, developed in the HindIII restriction enzyme site, consists of 4608 clones with an insert size of appr...
The deposition of the (1,3)-β-glucan cell wall polymer callose at sites of attempted penetration is a common plant defense response to intruding pathogens and part of the plant's innate immunity. Infection of the Fusarium graminearum disruption mutant Δfgl1, which lacks the effector lipase FGL1, is restricted to inoculated wheat (Triticum aestivum) spikelets, whereas the wild-type strain coloni...
Priming refers to a mechanism whereby plants are sensitized to respond faster and/or more strongly to future pathogen attack. Here, we demonstrate that preexposure to the green leaf volatile Z-3-hexenyl acetate (Z-3-HAC) primed wheat (Triticum aestivum) for enhanced defense against subsequent infection with the hemibiotrophic fungus Fusarium graminearum. Bioassays showed that, after priming wit...
