Mycoviruses are widespread in nature and often occur with dsRNA and positive-stranded RNA genomes. Recently, strong evidence from RNA sequencing analysis suggested that negative-stranded (-)ssRNA viruses could infect fungi. Here we describe a (-)ssRNA virus, Sclerotinia sclerotiorum negative-stranded RNA virus 1 (SsNSRV-1), isolated from a hypovirulent strain of Sclerotinia sclerotiorum. The co...

Summary Sclerotinia sclerotiorum is a pathogen which causes disease of oilseed rape. Severe plant infection contributes to decrease in the quality crop. It therefore important pay attention whether hybrids are highly tolerant this fungal at early stages breeding. In study, question interest there has been progress increasing tolerance new pathogen. Three years breeding experiments (2014, 2015, ...

Sclerotinia Head Rot (SHR), a disease caused by Sclerotinia sclerotiorum, is one of the most limiting factors in sunflower production. In this study, we identified genomic loci associated with resistance to SHR to support the development of assisted breeding strategies. We genotyped 114 Recombinant Inbred Lines (RILs) along with their parental lines (PAC2 -partially resistant-and RHA266 -suscep...

Plant growth stimulating and antagonistic properties of 7 bacterial isolates beneficial Enterobacter spp. (EPR1- EPR7) screened from the rhizospheric soil Phaseolus vulgaris plants growing in Garhwal Himalaya, Uttarakhand, India was studied against borne phytopathogen Sclerotinia sclerotiorum causes root rots various crops. Among isolates, EPR4 showed 64.8% reduction colony fungal pathogen dual...

Abstract Aqueous extracts of plants with proven biostimulant activity may have the potential to inhibit growth and development plant diseasecausing fungi. The use in such a role has many advantages including fact that are biodegradable, less costly, readily available. Therefore, aim this study was evaluate aqueous infusions, decoctions, macerates extracted from burdock roots, wormwood leaves, l...

A new C₉ monoterpenoid acid (litseacubebic acid, 1) and a known monoterpene lactone (6R)-3,7-dimethyl-7-hydroxy-2-octen-6-olide (2), along with three known compounds--vanillic acid (3), trans-3,4,5-trimethoxylcinnamyl alcohol (4), and oxonantenine (5)--were isolated with bioassay-guided purification from the fruit extract of Litsea cubeba collected in Tibet. The structure of 1 was elucidated by...

A major part of Trichoderma antifungal system consists of a number of genes encoding for an astonishing variety of secreted lytic enzymes including; e.g. chitinase, cellulases and β-1,3glucanases. The present work aimed to apply the mutagenesis technique in genetically breeding program of the bioagent Trichoderma viride to enhance three effective hydrolytic enzymes in their biocontrol abilities...

Two retrotransposons from the superfamilies Copia and Gypsy named as Copia-LTR_SS and Gypsy-LTR_SS, respectively, were identified in the genomic bank of Sclerotinia sclerotiorum. These transposable elements (TEs) contained direct and preserved long terminal repeats (LTR). Domains related to codified regions for gag protein, integrase, reverse transcriptase and RNAse H were identified in Copia-L...

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...
