differences between adenosine triphosphatases from monocotylous and dicotylous plants.the mitochondrial membrane-bound atpases of several plants were investigated. two distinct types were encountered. the mitochondrial atpases of castor bean (ricinus communis var. zanzibarensis, l.), cauliflower (brassica oleracea, l.), and scarlet runner (phaseolus coccineus, l.) were found to be inhibited by oligomycin, to have elevated molecular weights when separated from the organelles by ultrasonication and ammonium sulfate treatment and, subsequent to purification, to be cold-labile. on th ...197716659806
production of soft rot resistant calla lily by expressing a ferredoxin-like protein gene (pflp) in transgenic plants.an efficient protocol for the agrobacterium tumefaciens-mediated transformation of calla lily (zantedeschia elliottiana (w. wats.) engl. cultivar 'florex gold') is described. shoot basal discs were co-cultivated with a. tumefaciens c58c1 carrying a plasmid containing neomycin phosphotransferase (nptii) and plant ferredoxin-like protein (pflp) genes. after agrobacterium co-cultivation, the shoot basal discs were exposed to 100 mg l(-1) kanamycin for selection. twenty-eight out of 260 discs (10.8% ...200717033825
priming of antimicrobial phenolics during induced resistance response towards pectobacterium carotovorum in the ornamental monocot calla lily.calla lilies are herbaceous monocotyledonous plants that are highly sensitive to pectobacterium carotovorum, the causal agent of soft-rot disease. results demonstrate that, in response to elicitation using plant defense activators, the calla lily produces elevated levels of antimicrobial phenolics and that these compounds contribute to increased resistance against p. carotovorum, as shown by reduced bacterial proliferation in elicited leaves. the polyphenolic nature of the induced compounds was ...200717994692
serological comparison and molecular characterization for verification of calla lily chlorotic spot virus as a new tospovirus species belonging to watermelon silver mottle virus serogroup.abstract calla lily chlorotic spot virus (ccsv) isolated from central taiwan was recently identified as a tospovirus serologically but distantly related to watermelon silver mottle virus (wsmov). to clarify the serological relationship between the two viruses, rabbit polyclonal antibody (pab) to ccsv and mouse monoclonal antibodies (mabs) to wsmov np or ccsv np were produced in this investigation, using purified nucleocapsid protein (np) as immunogens. the pab to ccsv np reacted stronger with th ...200518943560
identification of common epitopes on a conserved region of nss proteins among tospoviruses of watermelon silver mottle virus serogroup.abstract the nss protein of watermelon silver mottle virus (wsmov) was expressed by a zucchini yellow mosaic virus (zymv) vector in squash. the expressed nss protein with a histidine tag and an additional nia protease cleavage sequence was isolated by ni(2+)-nta resins as a free-form protein and further eluted after sodium dodecyl sulfate-polyacrylamide gel electrophoresis for production of rabbit antiserum and mouse monoclonal antibodies (mabs). the rabbit antiserum strongly reacted with the ns ...200618943661
serological relationship between melon yellow spot virus and watermelon silver mottle virus and differential detection of the two viruses in cucurbits.melon yellow spot virus (mysv), a tentative member of the genus tospovirus, is considered a distinct serotype due to the lack of a serological relationship with other tospoviruses in its nucleocapsid protein (np). recently, a virus isolate collected from diseased watermelon in central taiwan (mysv-tw) was found to react with a rabbit antiserum (ras) prepared against the np of watermelon silver mottle virus (wsmov), and a monoclonal antibody (mab) prepared against the common epitope of the nss pr ...201020480192
