Marine sponges are a potential source of new molecules with diverse biological activities. We have previously isolated a sphingosine derivative, (9Z)-2-amino-docos-9-ene-1,3,13,14-tetraol (Haliscosamine) from the Moroccan sea sponge Haliclona viscosa. The aim of this study was to test Haliscosamine in vitro and in vivo for its antifungal activity against Fusarium oxysporum f.sp. melonis causing...

Horizontal chromosome transfer introduces host-specific pathogenicity among members of the Fusarium oxysporum species complex and is responsible for some of the most destructive and intractable plant diseases. This paper reports the genome sequence of F. oxysporum f. sp. melonis (NRRL 26406), a causal agent of Fusarium wilt disease on melon.

The aim of our research is the screening of extracts of marine sponges for their antifungal activity against phytopathogenic fungi. The in vitro screening of hydroalcoholic and organic extracts of ten marine sponges from Atlantic coast of Morocco against five phytopathogenic fungi (Fusarium oxysporum f.sp. melonis, Fusarium oxysporum f.sp. radicis-lycopersici, Fusarium oxysporum f.sp. ciceris, ...

Phytopathology 79:4095-1100. The ability of Fusarium oxysporum f. sp. melonis to colonize roots abundance of the four fungi was similar on all seven crops; nonpathoof a susceptible muskmelon cultivar and six crop species rot...

The unusual mixed valence CuII/CuI coordination polymer based on 2,5-bis(pyridine-2-yl)-1,3,4-thiadiazole [CuI3CuIIL2(SCN)5]n has been prepared by reaction between the thiadiazole ligand (L), CuCl2·2H2O and KSCN in H2O/CH3CN solution. title complex characterized using single-crystal X-ray diffraction, spectroscopic measurements, as well Hirshfeld surface analysis.

PG1, the major endopolygalacturonase of the vascular wilt pathogen Fusarium oxysporum, was secreted during growth on pectin by 10 of 12 isolates belonging to seven formae speciales, as determined with isoelectric focusing zymograms and sodium dodecyl sulfate-polyacrylamide gel electrophoresis gels. A Southern analysis of genomic DNA and PCR performed with gene-specific primers revealed that the...
