متن کاملConiothyrium minitans survival in soil and ability to infect sclerotia of Sclerotinia sclerotiorum
Survival of the sclerotial parasite Coniothyrium minitans in soil, when applied as spore suspension or colonised solid substrate (maizemeal-perlite) inocula, and ability to infect Sclerotinia sclerotiorum sclerotia incorporated into the soil after different times was assessed over 6 months. Unambiguous detection of the C. minitans isolate from the indigenous C. minitans soil population was achi...
متن کاملDisruption of the Coniothyrium minitans PIF1 DNA helicase gene impairs growth and capacity for sclerotial mycoparasitism.
A non-mycoparasitic restriction enzyme-mediated DNA integration (REMI) mutant of Coniothyrium minitans (R2427) contains two tandem plasmid copies integrated towards the 3' end of an ORF. The predicted polypeptide (845 aa) exhibits high similarity with DNA-helicase proteins from other filamentous fungi and yeasts that play a role in mitochondrial DNA maintenance and repair. Disruption of the C. ...
متن کاملکنترل بیولوژیک Sclerotinia sclerotiorum (عامل بیماری کپک سفید سیبزمینی) توسط گونه-های مختلف Trichoderma و Coniothyrium minitans
با شیوع خشکیدگی ساقه و مرگ زودهنگام بوتههای سیبزمینی در سطح وسیعی از مزارع استان همدان، به جداسازی و شناسایی عامل این بیماری اقدام شد. در نتیجه، عامل بیماری به عنوان Sclerotinia sclerotiorum شناسایی گردید. با توجه به خسارت این بیماری و عدم کنترل آسان آن توسط روشهای زراعی و شیمیایی، اثر بیوکنترلی پنج گونه تریکودرما شامل T. ceramicum، T. koningii، T. koningiopsis، T. virens و T. viridescens و...
متن کاملExpression of cmg1, an exo-beta-1,3-glucanase gene from Coniothyrium minitans, increases during sclerotial parasitism.
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...
