Genetic Analysis and Molecular Identification of Virulence in Xanthomonas oryzae pv. oryzae Isolates
Bacterial leaf blight (BLB) of rice is a very destructive disease worldwide and is caused by Xanthomonas oryzae pv. oryzae (Xoo). The aim of the present study was to examine if the Xoo virulence pathotypes obtained using phenotypic pathotyping could be confirmed using molecular approach. After screening of 60 Operon primers with genomic DNA of two Xoo isolates (virulent pathotype, Vr, and mildl...

متن کاملDistribution of Xanthomonas oryzae pv. oryzae DNA modification systems in Asia.
The presence or absence of two DNA modification systems, XorI and XorII, in 195 strains of Xanthomonas oryzae pv. oryzae collected from different major rice-growing countries of Asia was assessed. All four possible phenotypes (XorI+ XorII+, XorI+ XorII-, XorI- XorII+ and XorI- XorII-) were detected in the population at a ratio of approximately 1:2:2:2. The XorI+ XorII+ and XorI- XorII+ phenotyp...
متن کاملEffect of phenol on ultra structure and plasmid DNA of Xanthomonas oryzae pv. oryzae.
Most phenolic substances of plant origin are toxic to microorganisms and they confer some degree of protection to plants against phytopathogens. Xanthomonas oryzae pv. oryzae, bacterial blight pathogen of rice (Oryza sativa) was treated with phenol (monohydroxy benzene) and its effects on the morphology and cytological changes of the bacterium were studied. Total lysis of cells occurred with 5 ...
متن کاملAntagonistic Interactions Between Strains of Xanthomonas oryzae pv. oryzae.
ABSTRACT The ability of some phytopathogenic bacterial strains to inhibit the growth of others in mixed infections has been well documented. Here we report that such antagonistic interactions occur between several wild-type strains of the rice bacterial blight pathogen Xanthomonas oryzae pv. oryzae. In mixed inoculations, a wild-type Philippine strain was found to inhibit the growth of a wild-t...
