Interpretive Summary: Xanthomonas campestris is a Gram-negative plant pathogen that causes damage on agricultural and non-agricultural cruciferous plants, including Brassica crops, ornamentals, and weeds. Garlic mustard (Alliaria petiolata) is an aggressive, naturalized, non-native biennial cruciferous weed that effectively outcompetes North American flora and has few endemic pathogens or pests. Recently, black rot-like symptoms, including vascular wilt and chlorotic angular V-shaped leaf lesions, were reported on garlic mustard populations in Maryland. An isolate of X. campestris was determined to be the cause. This strain is of interest due to its potential for use in biological control of garlic mustard and understanding pathogen emergence in non-native plant species. Here, we report the complete genome sequence of the strain, FDWSRU 18048.

Technical Abstract: Xanthomonas campestris infections of non-native, invasive garlic mustard populations have been recently reported in the Eastern United States. Here, we report the genome sequence of the pathogenic X. campestris strain FDWSRU 18048. The genome is 4,978,515 bp and closely related to the genome of X. campestris pv. incanae CFBP2527.
