Draft genome sequences have been determined for the soybean pathogen Phytophthora sojae and the sudden oak death pathogen Phytophthora ramorum. Oömycetes such as these Phytophthora species share the kingdom Stramenopila with photosynthetic algae such as diatoms, and the presence of many Phytophthora genes of probable phototroph origin supports a photosynthetic ancestry for the stramenopiles. Co...
How plants recognize pathogens and activate defense is still mysterious. Direct interaction between pathogen avirulence (Avr) proteins and plant disease resistance proteins is the exception rather than the rule. During infection, Cladosporium fulvum secretes Avr2 protein into the apoplast of tomato leaves and, in the presence of the extracellular leucine-rich repeat receptor-like Cf-2 protein, ...
The potential role of extracellular elicitor proteins (elicitins) from Phytophthora species as avirulence factors in the interaction between Phytophthora and tobacco was examined. A survey of 85 Phytophthora isolates representing 14 species indicated that production of elicitin is almost ubiquitous except for isolates of Phytophthora parasitica from tobacco. The production of elicitins by isola...
Barley powdery mildew resistance (PM-R) genes control different infection phenotypes against avirulent strains of Blumeria graminis f. sp. hordei (Bgh). A subset of seven Pallas isolines, containing the PM-R genes Mla1, Mla12, Mlg, Mlk, Mlp and mlo5, revealed fast-, intermediateand slow-acting infection phenotypes. Scanning electron microscopy revealed the extent of Bgh development on each geno...
Abstract A collection of isolates the fungi Leptosphaeria maculans and L . biglobosa , which cause blackleg disease on Brassica napus (canola/oilseed rape) other Brassicaceae species, was assembled to represent global diversity these pathogens a resource for international research. The consists 226 (205 21 ) from 11 countries. genomes all 205 were sequenced, distribution identity avirulence gen...
conclusions the current study shows that the predominant hcv genotype among azerbaijani patients with established chronic hepatitis c is subtype 1b (71.1%) followed by subtype 3a (17.0%). results hcv genotyping of positive plasma samples demonstrated that predominant hcv subtype was noted for 1b (71.1%) followed by subtype 3a (17.0%), genotype 2 (6.8%), 1a (1.7%), and mixed infection (3.4%). th...
Plant disease resistance (R) proteins recognize matching pathogen avirulence proteins. Alleles of the pepper R gene Bs3 mediate recognition of the Xanthomonas campestris pv. vesicatoria (Xcv) type III effector protein AvrBs3 and its deletion derivative AvrBs3Deltarep16. Pepper Bs3 and its allelic variant Bs3-E encode flavin monooxygenases with a previously unknown structure and are transcriptio...
