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...

Individual plant growth-promoting rhizobacterial (PGPR) strains (Bacillus thuringiensis B2, Bacillus subtilis B10 and Enterobacter cloacae B16) their combination were used, with or without Pythium oligandrum, against Sclerotinia sclerotiorum. In vitro, all biological control agents (BCAs) reduced successfully hyphal growth of the targeted pathogenic fungus. They displayed antifungal activity by...

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...

Abstract Fungal pathogens are among the main destructive microorganisms for crops and ecosystems worldwide, causing substantial agricultural economic losses. Plant cell surface-localized lysin motif (LysM)-containing receptor-like kinases (RLKs) or proteins (RLPs) enhance plant resistance to fungal via sensing chitin, which is a conserved component of wall. Other types RLKs also regulate chitin...

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...

Mycoparasitism of fungal plant pathogens by Trichoderma species is a complex process that involves the production and coordinated secretion of cell-wall degrading enzymes. Genes implicated in mycoparasitism by Trichoderma atroviride contain motifs in the promoter region, designated MYRE1-MYRE4, that are proposed to act as binding sites for a global inducer of the mycoparasitic response. The aim...

This study was carried out to determine the antifungal effects of supernatant produced by bacterium Xenorhabdus szentirmaii, which is associated with soil-inhabiting entomopathogenic nematodes, on important plant pathogenic fungi, Fusarium verticilliodes, oxysporum f.sp lycopersici, radicis Botrytis cinerea, Sclerotinia sclerotiorum and Phytophthora nicotianae. The 1, 3, 5 7% concentrations X. ...

In sunflower, molecular markers for simple traits as, e.g., fertility restoration, high oleic acid content, herbicide tolerance or resistances to Plasmopara halstedii, Puccinia helianthi, or Orobanche cumana have been successfully used in marker-assisted breeding programs for years. However, agronomically important complex quantitative traits like yield, heterosis, drought tolerance, oil conten...

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...
