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. .

The Ionomics of Lettuce Infected by pv. .

Bacterial leaf spot (BLS) caused by pv. () places a major constraint on lettuce production worldwide. The most sustainable strategy known to date for controlling BLS is the use of resistant cultivars.

Rapid identification of and species and characterization of streptomycin resistance using quantitative PCR assays.

and are bacterial phytopathogens responsible for considerable yield losses in commercial pome fruit production. The pathogens, if left untreated, can compromise tree health and economically impact entire commercial fruit productions. Historically, the choice of effective control methods has been limited.

Proteome Analyses of Soil Bacteria Grown in the Presence of Potato Suberin, a Recalcitrant Biopolymer.

Suberin is a complex lipidic plant polymer found in various tissues including the potato periderm. The biological degradation of suberin is attributed to fungi. Soil samples from a potato field were used to inoculate a culture medium containing suberin as the carbon source, and a metaproteomic approach was used to identify bacteria that developed in the presence of suberin over a 60-d incubation period.
