Canadian isolates of Leptosphaeria maculans, the causal agent of blackleg of crucifers, were examined for genetic relatedness by the random amplified polymorphic DNA assay. DNA polymorphisms amplified with random decamer primers were used to distinguish three groups of isolates. Group 1 contained all isolates of the virulent pathotype, group 2 contained isolates of the avirulent pathotype from ...

The soft rot Enterobacteriaceae (SRE) Pectobacterium and Dickeya species (formerly classified as pectinolytic Erwinia spp.) cause important diseases on potato and other arable and horticultural crops. They may affect the growing potato plant causing blackleg and are responsible for tuber soft rot in storage thereby reducing yield and quality. Efficient and cost-effective detection and identific...

In all biological systems growth is defined as increase of chemical compounds. Bacteria can achieve to balanced growth if they are growing in a medium, which are completely adapted to it. Clostridium chauvoei, (Clostridium feseri) is an anaerobic, spore forming, motile, and polymorph bacteria, which its size varies from 0.5-1 to 3-8 micron and could be observed as individual bacterium, diplo, a...

Serratia plymuthica A30 is a Gram-negative bacterium expressing antagonistic activity toward blackleg- and soft rot-causing Dickeya sp. biovar 3 ("Dickeya solani"). Here, we present the draft genome sequence of strain A30, which has been isolated from rotten potato tuber tissue.

Pectobacterium atrosepticum strain CFBP6276 is a pectinolytic enterobacterium causing blackleg and soft rot of the stem and tuber of Solanum tuberosum. Its virulence is under the control of quorum sensing, with N-acylhomoserine lactones as communication signals. Here, we report the genome sequence of P. atrosepticum strain CFBP6276.

Key message "We identified both quantitative and quantitative resistance loci to Leptosphaeria maculans, a fungal pathogen, causing blackleg disease in canola. Several genome-wide significant associations were detected at known and new loci for blackleg resistance. We further validated statistically significant associations in four genetic mapping populations, demonstrating that GWAS marker loc...

Clostridium chauvoei is the etiological agent of blackleg, a disease of cattle and sheep with high mortality rates, causing severe economic losses in livestock production. Here, we report the draft genome sequence of the virulent C. chauvoei strain JF4335 (2.8 Mbp and 28% G+C content) and the annotation of the genome.

Pectobacterium wasabiae, originally causing soft rot disease in horseradish in Japan, was recently found to cause blackleg-like symptoms on potato in the United States, Canada, and Europe. A draft genome sequence of a Canadian potato isolate of P. wasabiae CFIA1002 will enhance the characterization of its pathogenicity and host specificity features.
