a total of twenty seven bacterial strains were isolated from cankerous tissues of apricot, nectarine, peach, plum, sour cherry and sweet cherry trees in tehran province and identified as pseudomonas syringae pv. syringae (pss), the causal agent of the bacterial canker disease, on the basis of lopat (levan production, oxidase test, potato rot, arginine dihydrolase and tobacco hypersensitive ...
بیماری شانکر باکتریایی هسته¬داران با عامل (pss) pseudomonas syringae pv. syringae یکی از بیماری های شایع درختان میوه هسته¬دار در استان¬های شمالی و مرکزی ایران می¬باشد. به منظور شناسایی جدایه های عامل بیماری، طی سال¬های 1390-1389، 105 جدایه به دست آمده از باغ های درختان میوه هسته¬دار واقع در مناطق مختلف استان¬های اردبیل، آذربایجان شرقی، گیلان، مازندران، خراسان رضوی، تهران و قزوین از نظر فنوتیپی،...
We present here data showing that the Avr proteins HrmA and AvrPto are secreted in culture via the native Hrp pathways from Pseudomonas syringae pathovars that produce these proteins. Moreover, their secretion is strongly affected by the temperature and pH of the culture medium. Both HrmA and AvrPto were secreted at their highest amounts when the temperature was between 18 and 22 degrees C and ...
Pseudomonas syringae pv. pisi comprises a number of races which fall into two phylogenetically distinct groups (designated I and II). Races are based on cultivar specificity in the host plant, pea (Pisum sativum), and are specified by the presence of avirulence genes. The avirulence gene avrPpiA1 is present on the chromosome of all strains examined in race 2, which belongs to phylogenetic group...
Pseudomonas syringae pv. porri, the causative agent of bacterial blight in leek (Allium porrum), is increasingly frequent causing problems in leek cultivation. Because of the current lack of control measures, novel bacteriophages were isolated to control this pathogen using phage therapy. Five novel phages were isolated from infected fields in Flanders (vB_PsyM_KIL1, vB_PsyM_KIL2, vB_PsyM_KIL3,...
Two cysteine proteinase genes of the papain family, NbCYP1 and NbCYP2, were amplified from cDNA of Nicotiana benthamiana leaves infected with the hemibiotrophic fungus Colletotrichum destructivum. Both genes showed peak expression corresponding with the switch from biotrophic to necrotrophic growth by C. destructivum at 72 h post-inoculation (HPI). For N. benthamiana inoculated with the incompa...
Epoxide hydrolase hydrates epoxides to vicinal diols in the phyto-oxylipin peroxygenase pathway resulting in the production of epoxy alcohols, dihydrodiols, triols and epoxides, including many lipid epoxides associated with resistance. Two epoxide hydrolase genes from Nicotiana benthamiana L., NbEH1.1 and NbEH1.2, were amplified from codingDNAof leaves during a susceptible response to the hemib...
The Pseudomonas syringae-Arabidopsis (Arabidopsis thaliana) interaction is an extensively studied plant-pathogen system. Arabidopsis possesses approximately 150 putative resistance genes encoding nucleotide binding site (NBS) and leucine-rich repeat (LRR) domain-containing proteins. The majority of these belong to the Toll/Interleukin-1 receptor (TIR)-NBS-LRR (TNL) class. Comparative studies wi...
