Incorporating resistance to Xanthomonas campestris pv, phaseoli into bean using the latent period as a resistance marker

Differential Pathogenicity of Xanthomonas campestris pv. phaseoli and X. fuscans subsp. fuscans Strains on Bean Genotypes with Common Blight Resistance

Genetic Diversity and Pathogenic Variation of Common Blight Bacteria (Xanthomonas campestris pv. phaseoli and X. campestris pv. phaseoli var. fuscans) Suggests Pathogen Coevolution with the Common Bean.

ABSTRACT Common bacterial blight (CBB), caused by Xanthomonas campestris pv. phaseoli and X. campestris pv. phaseoli var. fuscans, is one of the most important diseases of common bean (Phaseolus vulgaris) in East Africa and other bean-growing regions. Xanthomonad-like bacteria associated with CBB in Malawi and Tanzania, East Africa, and in Wisconsin, U.S., were characterized based on brown pigm...

Identification of Sources of Resistance to Xanthomonas campestris pv. campestris in Brassica napus Crops

Lema, M., Soengas, P., Velasco, P., Francisco, M., and Cartea, M. E. 2011. Identification of sources of resistance to Xanthomonas campestris pv. campestris in Brassica napus crops. Plant Dis. 95:292-297. Black rot, caused by Xanthomonas campestris pv. campestris, is one of the most important diseases affecting Brassica crops worldwide. Nine races have been differentiated in X. campestris pv. ca...

Genetic and physiological analysis of the major OxyR-regulated katA from Xanthomonas campestris pv. phaseoli.

katA encodes the major catalase that accounts for 90 % of the total catalase activity present in Xanthomonas campestris pv. phaseoli. katA is located upstream of an ORF designated ankA encoding a cytoplasmic membrane protein homologous to eukaryotic ankyrin. Transcriptional analysis of katA and ankA identified two katA transcripts: a major monocistronic katA transcript and a minor bicistronic k...

Important role for methionine sulfoxide reductase in the oxidative stress response of Xanthomonas campestris pv. phaseoli.

A methionine sulfoxide reductase gene (msrA) from Xanthomonas campestris pv. phaseoli has unique expression patterns and physiological function. msrA expression is growth dependent and is highly induced by exposure to oxidants and N-ethylmaleimide in an OxyR- and OhrR-independent manner. An msrA mutant showed increased sensitivity to oxidants but only during stationary phase.
