As a resource allocation strategy, plant growth and defense responses are generally mutually antagonistic. Brassinosteroid (BR) regulates many aspects of plant development and stress responses, however, genetic evidence of its integrated effects on plant growth and stress tolerance is lacking. We overexpressed the Arabidopsis BR biosynthetic gene AtDWF4 in the oilseed plant Brassica napus and s...

abstract sclerotinia sclerotiorum is the causal necrotroph pathogen with wide host range and showed various phenotipic intraspecies variability. considering to difficult identification of intraspecies heterogeneity on the basis of phenotypic factors, compatible mycelium groups introduced as an appropriate tool for classification and intraspecies heterogeneity distinction. in this research, 19 f...

The sclerotium is an important dormant body for many plant fungal pathogens. Here, we reported that a protein, named Ss-Sl2, is involved in sclerotial development of Sclerotinia sclerotiorum. Ss-Sl2 does not show significant homology with any protein of known function. Ss-Sl2 contains two putative PAN modules which were found in other proteins with diverse adhesion functions. Ss-Sl2 is a secret...

Most traits exhibit continuous variation resulting from the action of multiple genes modified by the environment. Quantitative trait loci (QTL) analysis consists in determining the location and number of genes that condition such quantitative traits and estimating the magnitude of individual gene effect by the use of analytical methods and detailed linkage map. Sclerotinia sclerotiorum and Diap...

The aim of this study was to inventory the types of plant growth-promoting rhizobacteria (PGPR) present in the rhizosphere of plants grown in soils contaminated with heavy metals, recalcitrant organics, petroleum sewage or salinity in China. We screened 1223 isolates for antifungal activity and about 24% inhibited Rhizoctonia solani or Sclerotinia sclerotiorum. Twenty-four strains inhibitory to...

The cyanobacterium Nostoc strain ATCC 53789, a known cryptophycin producer, was tested for its potential as a source of natural pesticides. The antibacterial, antifungal, insecticidal, nematocidal, and cytotoxic activities of methanolic extracts of the cyanobacterium were evaluated. Among the target organisms, nine fungi (Armillaria sp., Fusarium oxysporum f. sp. melonis, Penicillium expansum, ...

The sugarcane root endophyte Trichoderma virens 223 holds enormous potential as a sustainable alternative to chemical pesticides in the control of sugarcane diseases. Its efficacy as a biocontrol agent is thought to be associated with its production of chitinase enzymes, including N-acetyl-ß-D-glucosaminidases, chitobiosidases and endochitinases. We used targeted gene deletion and RNA-dependent...

Botrytis cinerea and Sclerotinia sclerotiorum secrete oxalic acid as a pathogenicity factor with a broad action. Consequently, it should be possible to interfere with the infection process by degrading oxalic acid during the interaction of these pathogens with their hosts. We have evaluated the potential of oxalate-degrading bacteria to protect plants against pathogenic fungi. Such bacteria wer...
