Summary In 1960 and 1961Phytophthora syringae Klebahn was isolated repeatedly from diseased bark of apple (Cox's Orange Pippin, James Grieve) and pear (Beurré Hardy).As far as the author is aware, natural infection of apple- and pear bark byPhytophthora syringae has not hitherto been reported, either in The Netherlands or elsewhere.gedetacheerd bij het Proefstation voor de Fruitteelt in de volle grond, Wilhelminadorp 相似文献

The flagellins purified from Pseudomonas syringae pv. tabaci induce a hypersensitive reaction in nonhost tomato cells. To investigate the role of flagella and flagellin in the compatible interaction, we generated two types of flagella-defective mutant. The fliC mutant lost the fliC gene that encodes flagellin protein, whereas the fliD mutant lost the fliD gene that encodes HAP2-capping protein. The two mutants had markedly reduced ability to cause disease symptoms in tobacco leaves. Furthermore, propagation of the mutants in tobacco leaves was less than that in wild-type pv. tabaci. Compared to the inoculation with wild-type pv. tabaci, inoculation with the two mutants did not markedly induce the expression of typical defense response-related genes such as PAL and hsr203J. Complementation of each fliC and fliD gene to the corresponding deficient mutant restored motility and virulence. These results indicate that flagella of P. syringae pv. tabaci are indispensable organelles for complete virulence on host tobacco plants. 相似文献
