متن کاملA pthA homolog from Xanthomonas axonopodis pv. citri responsible for host-specific suppression of virulence.
Strains of the plant-pathogenic bacterium Xanthomonas axonopodis pv. citri are differentiated into two groups with respect to aggressiveness (normal and weak) on Citrus grandis cultivars but not on other Citrus species such as Citrus sinensis. Random mutagenesis using the transposon Tn5 in X. axonopodis pv. citri strain KC21, which showed weak aggressiveness on a C. grandis cultivar, was used t...
متن کاملDifferential Gene Expression of Soybean [Glycine max (L.) Merr.] in Response to Xanthomonas axonopodis pv. glycines by Using Oligonulceotide Macroarray
Xanthomonas axonopodis pv. glycines (Xag) is a pathogen that causes bacterial leaf pustule (BLP) disease in soybeans grown in Korea and the southern United States. Typical and early symptoms of the disease are small, yellow to brown lesions with raised pustules that develop into large necrotic lesions leading to a substantial loss in yield due to premature defoliation. After Xag infects PI 9618...
متن کاملRole of rpfF in virulence and exoenzyme production of Xanthomonas axonopodis pv. glycines, the causal agent of bacterial pustule of soybean.
Ten strains of Xanthomonas axonopodis pv. glycines, the causal agent of bacterial pustule of soybean, which were isolated from various soybean growing regions of Thailand, produced an extracellular diffusible factor (DSF) related to a well-characterized quorum sensing molecule produced by other Xanthomonas spp. Genomic DNA of the 10 strains of X. axonopodis pv. glycines contained rpfF, a gene e...
متن کاملDefense-Related Responses in Fruit of the Nonhost Chili Pepper against Xanthomonas axonopodis pv. glycines Infection
Xanthomonas axonopodis pv. glycines (Xag ) is a necrotrophic bacterial pathogen of the soybean that causes bacterial pustules and is a nonhost pathogen of the chili pepper. In the current study, chili pepper fruit wound inoculated in planta with Xag 8ra formed necrotic lesions on the fruit surface and induced several structural and chemical barriers systemically in the fruit tissue. The initial...
