The goals of this investigation were to identify and evaluate the use of polymorphic microsatellite marker (PMM) analysis for molecular typing of seventeen plant pathogenic fungi. Primers for di-, tri-, and tetranucleotide loci were designed directly from the recently published genomic sequence of Mycospherlla graminicola and Fusarium graminearum. A total of 20 new microsatellite primers as eas...

The aim of this work is to determine the effect extraction method on yield, chemical composition, and antifungal activity cedarwood essential oils (EOs) from sawdust Moroccan Cedrus atlantica (C. atlantica). EOs were extracted by different methods: hydrodistillation, soxhlet, maceration, ultrasound. composition was determined using gas chromatography mass spectrometry (GC-MS) analysis. yields 5...

Fusarium spp. cause significant plant diseases and are responsible for food contamination with mycotoxins. Sustainable crop protection relies on a combination of different measures; among others, plants contain bioactive compounds providing antifungal antimicrobial properties. Coriander seed extracts have composition rich in fatty acids, sterols, essential oils, polyphenols etc. Therefore, this...

Lesion mimic mutants display spontaneous necrotic spots and chlorotic leaves as a result of mis-regulated cell death programmes. Typically these mutants have increased resistance to biotrophic pathogens but their response to facultative fungi that cause necrotrophic diseases is less well studied. The effect of altered cell death regulation on the development of disease caused by Ramularia collo...

forty monoconidial isolates of magnaporthe grisea were examined, for an identification of vegetative compatibility group and a characterization of genetic diversity, using rep-pcr genomic fingerprinting. the isolates were collected from weeds digitaria sanguinalis (crabgrass), setaria italica (foxtail millet), echinochloa crus-galli (barnyard millet), and some other unknown ones during 2003 - 2...

Fusarium culmorum F1 was found to produce and secrete into the culture medium several of 5-n-alkylresorcinols. The amount of resorcinolic lipids was 5.3 microg/g and 0.9 microg/l in mycelium and in post-culture liquid, respectively. First of all F. culmorum F1 produces saturated homologues with C15 to C25 side chains. The extract from the medium contained only homologues with shorter carbon cha...

Fusarium culmorum is one of the most harmful pathogens of durum wheat and is the causal agent of foot and root rot (FRR) disease. F. culmorum produces the mycotoxin deoxynivalenol (DON) that is involved in the pathogenic process. The role of the gene FcStuA, a StuA ortholog protein with an APSES domain sharing 98.5% homology to the FgStuA protein (FGSG10129), was determined by functional charac...

objective: fusarium species are prevalent contaminants of foodstuffs and agricultural crops.  they produce fumonisins, which are carcinogenic mycotoxins. the present study has evaluated maize and wheat samples from ten provinces in iran that were contaminated with fusarium species. special attention was paid to the ability of the isolates to produce fumonisin b1 (fb1) as a public health hazard....
