The taxonomy and evolutionary relationships among members of the genus Xanthomonas associated with tomato and pepper have been a matter of considerable controversy since their original description in 1921. These bacteria, which are a major affliction of tomato and pepper crops in warm and humid regions, were originally described as a single species, but subsequent research has shown the existen...
common bacterial blight (cbb) of bean caused by xanthomonas axonopodis pv. phaseoli is a seriously important disease that adversely affects the quantity and quality of seed. cultivation of resistant cultivars is the most effective method of the disease control. to identify disease resistant genotypes of selected beans, an experiment was conducted in agriculture and natural resources research ...
لوبیا به دلیل داشتن مقادیر بالای پروتیئن و انرژی، بعد از غلات و سیب زمینی از مهمترین محصولات کشاورزی به حساب می آید. بیماری های باکتریایی نظیر سوختگی معمولی لوبیاxanthomonas axonopodis pv. phaseoli))،سوختگی هاله دار لوبیا (pseudomonas savastonoi pv. phaseolicola) و پژمردگی باکتریایی لوبیا (curtobacterium flaccumfaciens pv. flaccufmaciens) از عوامل محدود کننده تولید این محصول در بسیاری از مناطق ...
The protein Clp from Xanthomonas axonopodis pv. citri regulates pathogenesis and is a member of the CRP (cyclic AMP receptor protein) superfamily. We show that unlike the DNA-binding activity of other members of this family, the DNA-binding activity of Clp is allosterically inhibited by its effector and that cyclic di-GMP serves as that effector at physiological concentrations.
The phytotoxin and polyketide antibiotic albicidin produced by Xanthomonas albilineans is a highly potent DNA gyrase inhibitor. Low yields of albicidin production have slowed studies of its chemical structure. Heterologous expression of albicidin biosynthetic genes in X. axonopodis pv. vesicatoria resulted in a sixfold increase in albicidin production, offering promising strategies for engineer...
A novel sucrose hydrolase (SUH) from Xanthomonas axonopodis pv. glycines, a causative agent of bacterial pustule disease on soybeans, was studied at the functional and molecular levels. SUH was shown to act rather specifically on sucrose (K(m) = 2.5 mM) but not on sucrose-6-phosphate. Protein analysis of purified SUH revealed that, in this monomeric enzyme with an estimated molecular mass of 70...
The gram-negative plant-pathogenic bacterium Xanthomonas campestris pv. vesicatoria is the causative agent of bacterial spot disease in pepper and tomato plants, which leads to economically important yield losses. This pathosystem has become a well-established model for studying bacterial infection strategies. Here, we present the whole-genome sequence of the pepper-pathogenic Xanthomonas campe...
