Xanthomonas euvesicatoria pv. alfalfae CFBP 3836 Genome sequencing and assembly
Xanthomonas alfalfae subsp. alfalfae affects mainly lucerne (Medicago sativa) but other hosts such as soybean (Glycine max), clover (Trifolium spp. ) and vetch (Vicia spp.) are recorded. X. alfalfae subsp. alfalfae is pathogenic on the legume model, Medicago truncatula. Lesions first appear on leaf as water-soaked spots surrounded by diffusible chlorotic area, then dry, turn yellow-brown and become papery. Severe defoliation is a common result of leaf infection. Post-emergence damping off, stunting of seedlings and also damage of lucerne stands are other symptoms. This seed-borne disease may cause severe losses in hot, moist environments, but losses are generally minor. Having access to Xaa genome will allow a better knowledge of the mechanisms involved in the interactions between a legume and a seed-borne foliar pathogen.
