A disease resistance gene in Arabidopsis with specificity for the avrPph3 gene of Pseudomonas syringae pv. phaseolicola.

چکیده
The avirulence gene avrPph3 from Pseudomonas syringae pv. phaseolicola was tested for its ability to convert virulent P. syringae pv. tomato strain DC3000 to avirulence on Arabidopsis. In F2 plants from a cross between resistant and susceptible ecotypes, the ratio of resistant to susceptible plants was approximately 3:1, indicating that resistance to DC3000(avrPph3) is determined by a single dominant locus, which we have designated RPS5. RPS5 was mapped to chromosome 1, between restriction fragment length polymorphism markers m241 and g3786.

بررسی اثر چند ژن بیماری زا در زندگی اپیفیتی (Pseudomonas syringae)
Pseudomonas syringae is a phytopathogenic bacterium with a wide host range. The biology of this bacterium consists of two phases. The first phase is the indication of disease on the host plant which generally appears in the form of necrosis on the aerial parts of plant (pathogenicity phase). The second phase is a rapid multiplication of bacteria on the aerial surface of the plant without inflic...

متن کاملArabidopsis NHO1 is required for general resistance against Pseudomonas bacteria.
Nonhost interactions are prevalent between plants and specialized phytopathogens. Although it has great potential for providing crop plants with durable resistance, nonhost resistance is poorly understood. Here, we show that nonhost resistance is controlled, at least in part, by general resistance. Arabidopsis plants are resistant to the nonhost pathogen Pseudomonas syringae pv phaseolicola NPS...
متن کاملDissection of Resistance Genes to Pseudomonas syringae pv. phaseolicola in UI3 Common Bean Cultivar
Few quantitative trait loci have been mapped for resistance to Pseudomonas syringae pv. phaseolicola in common bean. Two F₂ populations were developed from the host differential UI3 cultivar. The objective of this study was to further characterize the resistance to races 1, 5, 7 and 9 of Psp included in UI3. Using a QTL mapping approach, 16 and 11 main-effect QTLs for pod and primary leaf resis...
متن کاملA high-throughput, near-saturating screen for type III effector genes from Pseudomonas syringae.
Pseudomonas syringae strains deliver variable numbers of type III effector proteins into plant cells during infection. These proteins are required for virulence, because strains incapable of delivering them are nonpathogenic. We implemented a whole-genome, high-throughput screen for identifying P. syringae type III effector genes. The screen relied on FACS and an arabinose-inducible hrpL sigma ...
