Degradation of salicylic acid by Fusarium graminearum
Fungal Biology, 2019Fusarium head blight (FHB) is a major cereal crop disease, caused most frequently by the fungus Fusarium graminearum. We have previously demonstrated that F. graminearum can utilize SA as sole source of carbon to grow. In this current study, we further characterized selected four fungal SA-responsive genes that are predicted to encode salicylic acid ...

Activity and cell toxicology of fluazinam on Fusarium graminearum
Pesticide Biochemistry and Physiology, 2022Fusarium graminearum is an important plant pathogen and the causal agent of Fusarium head blight (FHB). At present, the principal method of controlling FHB is through fungicides. Fluazinam is an agent with strong broad-spectrum antifungal activity and has been used to control many diseases.

Ecophysiology of Fusarium graminearum and Fusarium proliferatum on sorghum grains
International Journal of Food MicrobiologyFusarium graminearum sensu stricto (F. graminearum s.s) and Fusarium proliferatum are species frequently isolated from sorghum grains. However, ecophysiology studies of these Fusarium species have not been carried out on sorghum grains. For this reason, the aim of this work was to evaluate the effects of different water activity levels (0.95, 0.98, 0 ...

Betaine transport in Fusarium graminearum
Mycological Research, 1994Fusarium graminearum A3/5 was found to possess a high-affinity transport system ( K m = 48 ± 6 μ m , V max = 8·9 ± 0·7 nmol mg −1 dry weight min −1 ) for betaine which was energy-dependent and constitutive. Glucose-starved mycelia showed a reduced uptake, whilst nitrogen-starved mycelia increased the rate of uptake 2·8-fold over a 3 h period ...

Fungicide Resistance in Fusarium graminearum Species Complex
Current Microbiology, 2022Fusariosis affects cereal grain crops worldwide and is responsible for devastating crops, reducing grain quality and yield, and producing strong mycotoxins. Benzimidazoles and triazoles were recommended to combat fusariosis; however, there were reports of resistance, making it necessary to reflect on the reasons for this occurrence. The purpose of this

Evaluation of Fusarium head blight in barley infected by Fusarium graminearum
Journal of Microbiology, 2013Fusarium head blight, which is primarily caused by Fusarium graminearum, is a devastating disease in the barley field. A real-time PCR protocol was developed to evaluate the growth of this pathogen in the host plant tissues. All four strains harbored the gene encoding ATP-BINDING CASSETTE TRANSPORTER (FgABC; FGSG_00541) as a single copy within their ...

Fusarium graminearum Genomics and Beyond
2014The filamentous ascomycete Fusarium graminearum has been studied intensively over decades. The fungus causes disease and produces mycotoxins on cereal crops, such as wheat, barley, and maize, threatening global food safety and human health. There is no effective approach to manage the disease or control mycotoxin production due to our limited ...

Chemically Defined Medium for the Production of Fusarium graminearum
Journal of Pharmaceutical Sciences, 1968A chemically defined medium for production of Fusarium graminearum has been developed and modified. A series of carbon and nitrogen sources was studied, resulting in the selection of glucose and ammonium succinate as primary substrates. Using the economic coefficient as a criterion for efficiency, the optimum concentrations for glucose and succinic ...

Conidial germination in the filamentous fungus Fusarium graminearum
Fungal Genetics and Biology, 2008The ascomycetous fungus Fusarium graminearum is an important plant pathogen causing Fusarium head blight disease of wheat and barley. To understand early developmental stages of this organism, we followed the germination of macroconidia microscopically to understand the timing of key events.

Genetic Diversity of Fusarium Graminearum in Europe and Asia
European Journal of Plant Pathology, 2004The biodiversity and phylogeny of Fusarium graminearum isolates originating from different geographical areas were analyzed using isozyme variation, β-tubulin and IGS sequences. Geographically distinct groups of isolates originating from different areas of the Russian Federation, China, Germany and Finland were studied.
