Influx and efflux of water and urea and electrolyte leakage are less for sunflower (Helianthus annuus) hypocotyl sections above lesions caused by Sclerotinia sclerotiorum than for those from healthy plants. Urea uptake by sections above lesions is reduced (celery, squash, and tomato) or unchanged (bean) in other hosts after Sclerotinia infection. Efflux of urea from sunflower hypocotyls is biph...

O fitopatógeno Sclerotinia sclerotiorum, causador da doença conhecida como mofo-branco acomete diversas culturas agrícolas em todo o mundo, seu alto grau de patogenicidade está associado à formação escleródios que atuam mecanismo resistência e sobrevivência. Considerando a necessidade métodos contribuam no desenvolvimento agrícola sem promover danos ao ambiente população, os agentes controle bi...

Vrsta Sclerotinia sclerotiorum (Lib.) De Bary najznačajniji je patogen koji uzrokuje značajne štete na uljaricama (suncokret, soja i uljana repica) širom svijeta. U područjima s vlažnijom hladnijom klimom može doći do velikih ekonomskih gubitaka. Karakteristični simptomi su bijele prevlake micelija zaraženim dijelovima biljaka pojava sklerocija. Budući da efikasnih mjera zaštite nema, nužno pro...

After four years of cold storage, dimethachlon resistance of two laboratory-induced resistant Sclerotinia sclerotiorum isolates SCG7 and LA50 declined by 99.5% and 98.9%, respectively, and cross resistance to iprodione and procymidone also declined dramatically. Along with the decline of fungicide resistance, osmotic sensitivity to sodium chloride and glucose decreased tremendously; mycelial gr...

Fungal plant pathogens are major threats to food security worldwide. Sclerotinia sclerotiorum and Botrytis cinerea are closely related Ascomycete plant pathogens causing mold diseases on hundreds of plant species. There is no genetic source of complete plant resistance to these broad host range pathogens known to date. Instead, natural plant populations show a continuum of resistance levels con...

During sclerotial infection of Sclerotinia sclerotiorum the mycoparasite Coniothyrium minitans penetrates through the host cell wall, which contains beta-1,3-glucan as its major component. A PCR-based strategy was used to clone a beta-1,3-glucanase-encoding gene, designated cmg1, from a cDNA library of the fungus. The nucleotide and deduced amino acid sequences of this gene showed high levels o...

Mitogen-activated protein kinases (MAPKs) play a central role in transferring signals and regulating gene expression in response to extracellular stimuli. An ortholog of the Saccharomyces cerevisiae cell wall integrity MAPK was identified in the phytopathogenic fungus Sclerotinia sclerotiorum. Disruption of the S. sclerotiorum Smk3 gene severely reduced virulence on intact host plant leaves but...
