investigation of pathogenisity and genotypic diversity of xanthomonas oryzae pv. oryzae caused rice bacterial blight
to investigation of pathogenisity and genotype diversity of xanthomonas oryzae pv. oryzae (xoo) caused rice bacterial blight, several samples were collected from paddy field of rice in rasht-sangar, soumeh sara, rezvan shahr, daboudasht amol and rice-institute-research guilan during the summer of 2012, from plants that showed blight and yellowing in their leaves. bacterial isolates were identif...
متن کاملPathotype and Genetic Diversity amongst Indian Isolates of Xanthomonas oryzae pv. oryzae
A number of rice resistance genes, called Xa genes, have been identified that confer resistance against various strains of Xanthomonas oryzae pv. oryzae (Xoo), the causal agent of bacterial blight. An understanding of pathotype diversity within the target pathogen population is required for identifying the Xa genes that are to be deployed for development of resistant rice cultivars. Among 1024 ...
متن کاملMolecular determinants of disease and resistance in interactions of Xanthomonas oryzae pv. oryzae and rice.
Xanthomonas oryzae pv. oryzae is the causal agent of rice bacterial blight disease. Numerous genes critical for virulence have been identified. This article reviews current knowledge on the molecular mechanisms of X. oryzae pv. oryzae virulence.
متن کاملAlteration of TGA factor activity in rice results in enhanced tolerance to Xanthomonas oryzae pv. oryzae.
In dicotyledonous plants broad-spectrum resistance to pathogens is established after the induction of the systemic acquired resistance (SAR) response. In Arabidopsis the NPR1 protein can regulate SAR by interacting with members of the TGA class of basic, leucine-zipper transcription factors to alter pathogenesis-related (PR) gene expression. Overexpression of (At)NPR1 in Arabidopsis enhances re...
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...
