First Report of Xanthomonas phaseoli pv. dieffenbachiae Causing Bacterial Leaf Blight on Anthurium andreanum in Mexico

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...

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

Plant regeneration of Anthurium andreanum cv Rubrun

To establish an efficient regeneration system for Anthurium andreanum cv Rubrun, seeds from plant spadixes were germinated on a medium supplemented with 2.2 μ M BA. After 2 weeks, 74% of the seeds germinated and four weeks later, micro-cuttings from these plantlets were subcultured on a medium containing 4.4 μ M BA and 0.05 μ M NAA. On average, 3.6 shoots per explant were obtained. Four weeks o...

Biological control of Xanthomonas Oryzae pv. Oryzae causing rice bacterial blight disease by Streptomyces toxytricini VN08-A-12, isolated from soil and leaf-litter samples in Vietnam.

A total of 2690 actinomycete strains were screened as potential biological control agents in controlling rice bacterial blight (BB) in Vietnam. From these microorganisms, seventeen actinomycete strains were found to be capable of inhibiting all 10 major Xoo races isolated from Xoo-infected rice leaves. One strain, namely VN08-A-12, contained effective characteristics in selectively inhibiting a...

Study of Biochemical and Molecular Changes of Iranian Rice Cultivars in Interaction with Bacterial Pathogen Xanthomonas oryzae pv. oryzae Causes Leaf Blight Disease

Rice bacterial blight caused by Xanthamonos oryzae pv. oryzae is one of the most destructive bacterial diseases of rice in some areas of rice cultivation in the world, especially in the tropics of Asia. The low efficiency of disease management methods, especially chemical methods, has led to more research on recognizing resistant cultivars and understanding resistance mechanisms through the stu...
