Virulence Determinants Are Unevenly Distributed Within Species and Strains Causing Potato Common Scab in the Province of Quebec, Canada.

Potato common scab is an important bacterial disease afflicting potatoes around the world. Better knowledge of the local spp. populations causing this disease is key to developing durable control strategies.

Winter Rye Cover Crops Shelter Competent Squash Phyllosphere Bacteria to Reduce pv. Growth and Angular Leaf Spot Symptoms.

Cover crops, a soil conservation practice, can contribute to reducing disease pressure caused by , considered one of the most important bacterial plant pathogens. We recently demonstrated that the phyllosphere (leaf surface) bacterial community structure changed when squash () was grown with a rye () cover crop treatment, followed by a decrease of angular leaf spot disease symptoms on squash caused by pv. .

Identification and genomic characterization of spp. displaying biocontrol activity against in lettuce.

Lettuce is an economically major leafy vegetable that is affected by numerous diseases. One of the most devastating diseases of lettuce is white mold caused by . Control methods for this fungus are limited due to the development of genetic resistance to commonly used fungicides, the large number of hosts and the long-term survival of sclerotia in soil.

Genome Sequences of Two Plant-Beneficial Strains Isolated from Agricultural Soils in the Province of Quebec, Canada.

Two strains, B21-013 and B21-037, were isolated from agricultural soils located in the province of Quebec, Canada, as part of a screening for plant-beneficial bacteria able to suppress Xanthomonas hortorum pv. and other lettuce bacterial pathogens. Here, we report the genome sequences of these two organisms.

Harnessing the genomic diversity of strains against lettuce bacterial pathogens.

Lettuce is a major vegetable crop worldwide that is affected by numerous bacterial pathogens, including pv. , , and . Control methods are scarce and not always effective.
