Sclerotinia stem rot caused by Sclerotinia sclerotiorum is one of the most devastating diseases in many important crops including Brassica napus worldwide. Quantitative resistance is the only source for genetic improvement of Sclerotinia-resistance in B. napus, but the molecular basis for such a resistance is largely unknown. Here, we performed dynamic transcriptomic analyses to understand the ...

Pseudomonas sp. DF41 is a biocontrol agent capable of suppressing Sclerotinia sclerotiorum-mediated stem rot of canola. Using transposon mutagenesis, we identified two mutants with greatly reduced antifungal (AF) activity. The first mutant had an insertion in gacS, forming part of the GacS/GacA regulatory system. The second mutation was in a gene involved in lipopeptide (LP) synthesis suggestin...

Bacillus amyloliquefaciens strain NJZJSB3 has shown antagonism of several phytopathogens in vitro, especially Sclerotinia sclerotiorum. Both the broth culture and cell suspension of strain NJZJSB3 could completely protect the detached leaves of canola (Brassica napus) from S. sclerotiorum infection. In pot experiments, the application of strain NJZJSB3 cell suspension (10(8) CFU/ml) decreased t...
