متن کاملPathogenic and Genetic Relatedness Among Xanthomonas axonopodis pv. allii and Other Pathovars of X. axonopodis.
ABSTRACT Xanthomonas axonopodis pv. allii is phenotypically and genetically diverse and its relationship to other X. axonopodis pathovars within DNA homology group 9.2 is unknown. In growth chamber experiments, disease symptoms were produced on onion only by inoculation with X. axonopodis pv. allii. Citrus bacterial spot symptoms were induced by X. axonopodis pvs. alfalfae, itrumelo, and allii ...
متن کاملTransformation of Xanthomonas axonopodis pv. citri by Electroporation
This study describes the use of electroporation for transforming Xanthomonas axonopodis pv. citri (Xac), the causal agent of citrus (Citrus spp.) canker. It also evaluates the methodology used for this species under different electrical parameters. The bacterium used in the study (Xac 306) was the same strain used for recent complete sequencing of the organism. The use of a plasmid (pUFR047, ge...
متن کاملGenetic structure and population dynamics of Xanthomonas axonopodis pv. manihotis in Colombia from 1995 to 1999.
Restriction fragment length polymorphisms (RFLPs) were used to study the population genetics and temporal dynamics of the cassava bacterial pathogen Xanthomonas axonopodis pv. manihotis. The population dynamics were addressed by comparing samples collected from 1995 to 1999 from six locations, spanning four different edaphoclimatic zones (ECZs). Forty-five different X. axonopodis pv. manihotis ...
متن کاملSpectroscopic Characterization of the Exopolysaccharide of Xanthomonas axonopodis pv. citri in Cu2+ Resistance Mechanism
Analizou-se o papel do exopolissacarídeo (EPS) no mecanismo de resistência ao Cu da Xanthomonas axonopodis pv. citri (Xac) com as espectroscopias de infravermelho com transformada de Fourier (FTIR), ressonância paramagnética eletrônica (RPE) e ressonância magnética nuclear (RMN). Os dados de FTIR demonstraram que as células cultivadas na presença de 0.2 mmol L de CuSO4 produziram uma maior quan...
