First report of Xanthomonas vasicola causing bacterial leaf streak on corn in the United States
Plant Disease 101 (6), 1030-1030
Abstract: During 2014 and 2015, maize plants (Zea mays) grown in Nebraska, U.S.A. were observed with symptoms of long, dark, yellow to brown, water-soaked, linear lesions confined to the interveinal spaces of the leaves. Initial symptoms appeared as small water-soaked flecks that expanded between veins to form irregular lesions. In some cases, the disease progressed to cover 40 to 50% of the leaf area. The bacterium Xanthomonas vasicola was isolated from the diseased plants. The identification was based on PCR analysis and nucleotide sequencing of the isolates. Pathogenicity of the isolates was demonstrated by inoculation and re-isolation.
