| isolation of viruses by electro-extraction of infected plants. | the isolation of viruses from infected plant material by a process termed electro-extraction appeared to be a convenient and simple method of obtaining viruses in a fair state of purity. the method has the advantage over the conventional methods of virus purification that the infected plant tissue is not disintegrated and that organic solvents such as chloroform and butanol are avoided. the procedure used was demonstrated on the extraction of tobacco mosaic virus (tmv) from infected tobacco and ... | 1977 | 909872 |
| inhibition of turnip yellow mosaic virus synthesis by pyrimidine analogues. | the pyrimidine analogues 2-thiouracil, 2-thiouridine, 6-azauracil and 6-azauridine all inhibited the synthesis of turnip yellow mosaic virus (tymv) and increased the synthesis of empty virus protein shells in infected chinese cabbage leaf discs. uracil and uridine reversed these effects. 2-thiouracil also reduced the utp pool in tymv infected leaf discs. the results are consistent with the suggestion that these analogues or their in vivo derivatives affect virus synthesis by inhibiting the biosy ... | 1976 | 989025 |
| herbicidins a and b, two new antibiotics with herbicidal activity. i. producing organism and biological activities. | herbicidins a and b, two new antibiotics with selective and contact herbicidal activity, were produced by a new species of streptomyces designated as s. sagononensis. among tested microorganisms, herbicidins indicated some activity against fungi in vitro and xanthomonas oryzae in vivo. their characteristic features were brought into relief by their selective and contact killing effect on many dicotyledonous plant as well as their inhibition of germination of the plant seeds, such as chinese cabb ... | 1976 | 993127 |
| a chlorophyll-protein complex lacking in photosystem i mutants of chlamydomonas reinhardtii. | sodium dodecyl sulfate gel electrophoresis of unheated, detergent-solubilized thylakoid membranes of chlamydomonas reinhardtii gives two chlorophyll-protein complexes. chlorophyll-protein complex i (cp i) is the blue-green in color and can be dissociated by heat into "free" chlorophyll and a constituent polypeptide (polypeptide 2; mol wt 66,000). similar experiments with spinach and chinese cabbage show that the higher plant cp i contains an equivalent polypeptide but of slightly lower molecular ... | 1975 | 1194353 |
| effects of kinetin on phosphorylation of leaf membrane proteins. | isolated chinese cabbage leaf membranes were phosphorylated by membrane-associated protein kinase(s) in the presence or [gamma-32p]atp. membrane-associated 32p radioactivity appeared to be bound to membrane proteins. both smooth cell membranes and chloroplast lamellae reacted with atp. phosphorylation of the membranes was inhibited by ca2+ and partially inhibited by kinetin or 6-benzyladenine. the possibility that cytokinin effects on membrane phosphorylation might increase ion availability was ... | 1976 | 1252471 |
| location, rate and asymmetry of ds-rna synthesis during replication of tymv in chinese cabbage. | the ds-rna induced by tymv infection in the nuclei of infected chinese cabbage leaf cells became labelled with [32p]phosphate most rapidly before production of virus could be detected. in contrast, the ds-rna associated with the chloroplasts became labelled most rapidly during the period of maximum virus production. | 1976 | 1275406 |

| localization of cauliflower mosaic virus in the cell nucleus of brassica pekinensis l. | cauliflower mosaic virus (camv) particles were observed in the nuclei of xylem parenchyma cells in brassica pekinensis l. doubly infected by camv and turnip mosaic virus (tumv). camv particles were aggregated in the nucleoplasm but not embedded in viroplasms. this phenomenon was not detected in cell nuclei of mesophyll tissue. typical features associated with infection by either camv or tumv normally occurred in the cytoplasm of cells of both tissues: two types of viroplasms with embedded camv p ... | 1992 | 1410828 |
| turnip yellow mosaic virus variants produced from dna clones encoding their genomes. | full-length dsdna clones that encode the genomes of two australian turnip yellow mosaic isolates, tymv-bl and tymv-cl have been constructed. these clones were transcribed to give 6.3 kb capped ssrna which infects chinese cabbages to give symptoms indistinguishable from those produced by the parental viruses. extensions of up to 26 nucleotides at the 3' end of the tymv-bl clone delay infections, but virus particles isolated from these plants 4 weeks after inoculation contain rna with the original ... | 1992 | 1456892 |
| second-site suppressor mutations assist in studying the function of the 3' noncoding region of turnip yellow mosaic virus rna. | the 3' noncoding region of turnip yellow mosaic virus rna includes an 82-nucleotide-long trna-like structure domain and a short upstream region that includes a potential pseudoknot overlapping the coat protein termination codon. genomic rnas with point mutations in the 3' noncoding region that result in poor replication in protoplasts and no systemic symptoms in planta were inoculated onto chinese cabbage plants in an effort to obtain second-site suppressor mutations. putative second-site suppre ... | 1992 | 1501271 |
| [nucleic acid components in carbohydrate-rich food]. | the content of nucleic acid components in numerous foods, especially carbohydrate-rich ones, has been investigated. the data obtained for bases (purines and pyrimidines) were calculated as nucleic-acid equivalents (rna or dna); the imp content was calculated from the measured content of hypoxanthine. not only did cultivated plants such as cereals and pulses show a high rna-equivalent content but also vegetables such as spinach, leek, broccoli, chinese cabbage and cauliflower. we found the same r ... | 1990 | 1689090 |
| expression of orf-69 of turnip yellow mosaic virus is necessary for viral spread in plants. | turnip yellow mosaic virus (tymv) rna has two extensively overlapping open reading frames (orfs) encoding noncapsid proteins. the longest of these, orf-206, is essential for rna replication. we have investigated the expression and role of orf-69 (encoding a protein with a mw of 69k) using specific antiserum and mutant genomic rnas designed to interrupt orf-69 expression. tyc69 antiserum immunoprecipitated a protein with an apparent mw of 75k (p69) from in vitro translations of tymv rna. mutant r ... | 1992 | 1736523 |
| turnip yellow mosaic virus rnas with anticodon loop substitutions that result in decreased valylation fail to replicate efficiently. | single and multiple nucleotide substitutions have been introduced into the anticodon loop of the trna-like structure of turnip yellow mosaic virus (tymv) genomic rna. we studied the effects of these mutations on in vitro valylation and on replication in chinese cabbage protoplasts and plants. only those mutants capable of efficient and complete valylation showed efficient replication in protoplasts and gave rise to systemic symptoms in whole plants. mutants that accepted valine inefficiently (in ... | 1991 | 2033666 |
| first isolation of xanthomonas campestris from the blood of a chinese woman. | xanthomonas campestris isolated from the blood of a patient with a fever was first reported. xanthomonas campestris is a bacterium that can cause black rot of some vegetables, such as rape. chinese cabbage, etc. human infection due to x. campestris has not been reported so far. the characteristics of this organism, including morphology, staining, physiology and biochemistry were studied. we believe that x. campestris is also one of the opportunistic pathogens, which can infect compromised host. | 1990 | 2118062 |
| induction of nitroarenes in cigarette smoke condensate treated with nitrate. | samples of cigarette smoke condensates (cscs) treated with nitric acid or chinese cabbage pickles having a high nitrate content strongly mutated salmonella typhimurium strain ta98; the benzene/ethanol extract after these treatments induced 1800 and 820 revertants, respectively, per mg of extract for strain ta98 in the absence of s9 mix. the major mutagens in these materials were found to be 1-nitropyrene and 1,3-dinitropyrene on the basis of the result of gas chromatography/mass spectrometry and ... | 1990 | 2155483 |
