| murine toxicit of agrobacterium tumefaciens. | eleven strains of the crown gall organism, agrobacterium tumefaciens, tested by intraperitoneal injection into mice, were lethal within 48 hr. five other species had some lethal strains. the lethal effect of a. tumefaciens appeared to be the result of a toxic rather than an infectious process, since histopathological anomalies were not found in mice injected with live cultures and since heat-killed cultures were lethal. the murine toxin disappeared when a. tumefaciens was grown at 36 c and reapp ... | 1968 | 5643064 |
| methylation of the cellular lipid of methionine-requiring agrobacterium tumefaciens. | mutants of agrobacterium tumefaciens requiring methionine for growth on a solid basal medium were induced by the use of n-methyl-n'-nitro-n-nitrosoguanidine. in addition to the difference of mutant strains, the extent of methionine dependency differed in a liquid basal medium and in the presence of aspartate or fumarate. when ((14)c-methyl)-methionine was added to strain wm-11 growing in a prescribed basal medium, incorporation of (14)c into the cellular "residue" fraction and polar "n-methylate ... | 1968 | 5669890 |

| conversion of glucose-1-phosphate to 3-keto-glucose-1-phosphate by cells of agrobacterium tumefaciens. | incubation of resting cells of agrobacterium tumefaciens with glucose-1-phosphate resulted in the accumulation of a new sugar phosphate in the suspending medium. approximately 80% of the glucose-1-phosphate consumed was converted to the new compound, which was identified as alpha-d-ribo-hexopyranosyl-3-ulose-1-phosphate (3-ketoglucose-1-phosphate). both utilization of glucose-1-phosphate and accumulation of 3-ketoglucose-1-phosphate were inhibited by 2,4-dinitrophenol, polymyxin, and d-glucose, ... | 1969 | 4304223 |
| hexuronic acid dehydrogenase of agrobacterium tumefaciens. | growth of agrobacterium tumefaciens on d-glucuronic acid (glcua) or d-galacturonic acid (galua) induces formation of hexuronic acid dehydrogenase [d-aldohexuronic acid: nicotinamide adenine dinucleotide (nad) oxidoreductase]. the dehydrogenase, which irreversibly converts glcua or galua to the corresponding hexaric acid with the concomitant reduction of nad, but not of nicotinamide adenine dinucleotide phosphate was purified 60-fold by mncl(2) treatment, (nh(4))(2)so(4) fractionation, chromatogr ... | 1969 | 4313130 |
| bacterial attachment to a specific wound site as an essential stage in tumor initiation by agrobacterium tumefaciens. | the number of tumors initiated by agrobacterium tumefaciens strain b6 on primary pinto bean leaves was decreased when cells of an avirulent strain (iibnv6) were included in the inoculum. with sufficient b6 cells to initiate ca. 50% of the maximal number of tumors per leaf, inhibition was detected at a 1:1 ratio of b6 to iibnv6 cells and increased linearly with the logarithm of the number of iibnv6. varying the number of b6 in the presence of a constant number of iibnv6 or varying the number of b ... | 1969 | 5773014 |
| bacteriophage release in a lysogenic strain of agrobacterium tumefaciens. | bacteriophage release in a lysogenic strain of agrobacterium tumefaciens v-1 is temperature-sensitive. at 25 c and 30 c, phage was released in a ratio of 1 plaque-forming unit per 100 bacteria; at 35 c, although bacterial growth was not inhibited, phage release was suppressed. phage synthesis was induced by heat shock, 42 c for 30 min, ultraviolet irradiation, and mitomycin c. induction by ultraviolet light was unusual-an immediate rise in phage titer followed irradiation. a large increase occur ... | 1969 | 5774138 |

| physiological comparisons of pith callus with crown-gall and genetic tumors of nicotiana glauca, n. langsdorffii, and n. glauca-langsdorffii grown in vitro. i. tumor induction and proliferation. | agrobacterium tumefaciens b-6 and t-37 strains, inoculated into nicotiana glauca, n. langsdorffii, and their interspecific hybrid, which forms genetic (spontaneous) tumors as well, initiate amorphous tumors from the b-6 strain and organoid tumors (aberrant roots, stems, and buds) from the t-37 strain. in the hybrid, the critical point was to induce crown gall tumors at the site of wounding and not spontaneous genetic tumors. to succeed, this inoculation had to be made at a very early (5-6 leaf s ... | 1969 | 16657159 |
| physiological comparisons of pith callus with crown-gall and genetic tumors of nicotiana glauca, n. langsdorffii, and n. glauca-langsdorffii grown in vitro. ii. nutritional physiology. | explants of genetic tumors, tumors initiated by agrobacterium tumefaciens strains b-6 and t-37, and excised pith plugs from nicotiana glauca, n. langsdorffii, and n. glauca-langsdorffii were cultured on murashige and skoog medium. all cultures, pith callus and tumors with the exception of n. langsdorffii pith grew on this medium. addition of glutamine to the medium resulted in highly organoid growth in n. langsdorffii pith. in order to have material comparable to other pith cultures, n. langsdor ... | 1969 | 16657160 |
| studies on auxin protectors. vii. association of auxin protectors with crown gall development in sunflower stems. | mature sunflower internodes contain only very low concentrations of auxin protectors. wounding such internodes results in a temporary increase of protector substances. inoculating the wounds with a virulent strain of agrobacterium tumefaciens conn results in a dramatic rise in protector substances, particularly the very high molecular weight protector "a", which continues as the tumors develop. the levels attained in tumor tissue are comparable to those normally encountered in meristematic tissu ... | 1969 | 16657184 |
| transmission of an agrobacterium tumefaciens phage by pristionchus iheriteiri. | pristionchus lheriteiri (maupas) paramonov, a saprozoic nematode, served as a carrier of an unnamed phage of agrobacterium tumefaciens (smith and townsend) conn. viable phage particles passed through the nematode, caused lysis and formed typical plaques on agar plates seeded to a. tumefaciens. phage retention by carrier nematodes was extended several hr by restricting food intake. female nematodes accumulated phage in greater quantities and more rapidly than male nematodes. | 1969 | 19325671 |
| saprozoic nematodes as carriers and disseminators of plant pathogenic bacteria. | the plant pathogenic bacteria agrobacterium tumefaciens (smith and townsend) conn. (strain 5-14 deep), erwinia amylovora (burill) winslow et al., e. carotovora (jones) holland and pseudornonas phaseolicola (burk.) dows. (icpb-pm3) and the red-pigmented non-pathogen serratia marcescens bizio were hosts for the saprozoic nematode pristionchus iheritieri (maupas, 1919) paramonov. viable bacteria survived passage through the nematode and produced typical colonies on nutrient agar plates. female nema ... | 1969 | 19325679 |
| lysopine and octopine promote crown-gall tumor growth in vivo. | growth of tumors induced on primary leaves of bean plants by agrobacterium tumefaciens was increased by the addition of lysopine and octopine. a detectable response was observed when as little as 1 microgram of these compounds was added per leaf, and the mean volume of the tumors was increased two- to threefold when greater amounts were applied. the specificity of the response and the unique association of these compounds with the tumors suggest that endogenous lysopine and octopine contribute t ... | 1970 | 17833501 |
| gas-liquid chromatographic isolation of cytokinins from natural sources: 6-(3-methyl-2-butenylamino) purine from agrobacterium tumefaciens. | gas-liquid chromatographic retention times for 20 purines or purine nucleosides, 14 of which are highly active cytokinins, are reported. with one exception, all of the naturally occurring cytokinins are separated.ethyl acetate extraction of yeast transfer rna hydrolysates and of culture filtrates of agrobacterium tumefaciens gave sufficient concentration of the naturally occurring cytokinins for immediate gas-liquid chromatography. this procedure permitted the detection of 6-(3-methyl-2-butenyla ... | 1970 | 16657339 |
| bioassay and attributes of a growth factor associated with crown gall tumors. | an improved bioassay is described for a factor that promotes tumor growth which was first obtained from extracts of pinto bean leaves with crown gall tumors. sixteen primary pinto bean leaves per sample are inoculated with sufficient agrobacterium tumefaciens to initiate about 5 to 10 tumors per leaf and treated with tumor growth factor at day 3 after inoculation. the diameters of 30 to 48 round tumors (no more than 3 randomly selected per leaf) are measured per test sample at day 6. mean tumor ... | 1970 | 16657534 |
| enhancement of agrobacterium tumefaciens infectivity by chlorpromazine hydrochloride. | the tumor-initiating ability of agrobacterium tumefaciens was enhanced two- to threefold after a preinoculation exposure to the phenothiazine derivative chlorpromazine hydrochloride. the mean number of tumors initiated per viable bacterium on pinto bean leaves was greatest after a 1-hr exposure to 15 mug of the drug per ml. chlorpromazine had no significant effect on tumor initiation when applied to previously inoculated leaves. chlorpromazine at 10 mug/ml was bacteriostatic; concentrations of 2 ... | 1970 | 16557863 |

| active transport of glucose-1-phosphate in agrobacterium tumefaciens. | the presence of an active transport system for glucose-1-phosphate in agrobacterium tumefaciens was demonstrated from the following observations. (i) the bacterium could grow on a medium containing glucose-1-phosphate as carbon source; (ii) the entry of glucose-1-phosphate into the resting cells occurred against concentration gradient obeying michaelis-menten kinetics; and (iii) the entry reaction was energy-dependent. the transport system for glucose-1-phosphate was formed inducibly by growing ... | 1970 | 5438042 |
| alpha-3-ketoglucosidase of agrobacterium tumefaciens. | a 3-ketosucrose-degrading enzyme was purified 80-fold from the sonic extracts of agrobacterium tumefaciens iam 1525 grown on a sucrose-containing medium. the enzyme catalyzes hydrolysis of alpha-3-ketoglucosides such as 3-ketosucrose, 3-ketotrehalose, 3-ketomaltose, and 3-ketoglucose-1-phosphate but not of beta-3-ketoglucosides, beta-3-ketogalactosides, and other glycosides such as sucrose, trehalose, maltose, glucose-1-phosphate, cellobiose, lactose, or raffinose. from the strict substrate spec ... | 1970 | 5438043 |

| tumor induction by agrobacterium tumefaciens: specific transfer of bacterial deoxyribonucleic acid to plant tissue. | when agrobacterium tumefaciens cells grown in the presence of tritiated thymidine to label specifically the bacterial deoxyribonucleic acid (dna) are incubated with carrot root tissue for short periods of time, an appreciable fraction of the label becomes firmly associated with the root tissue. such association is not observed in identical experiments when a. tumefaciens cell ribonucleic acid or protein are labeled. the extent of the retention of thymidine-derived label from bacterial cells by t ... | 1971 | 5167810 |
| evidence for the presence of bacteria-specific proteins in sterile crown gall tumor tissue. | cross-reacting antigens were found in bacteria-free crown gall tumor tissue tested with serum prepared against agrobacterium tumefaciens (smith and towns.) conn., but no such antigens were detected in callus tissue. soluble proteins from tumor tissue, callus tissue, and the crown gall bacteria were fractionated on a deae-sephadex (a-50) column. the diethylaminoethyl-sephadex elution profile for tumor tissue showed three protein fractions that were not detected in the callus tissue. two of these ... | 1971 | 16657748 |
| two auxin oxidases with distinct antigenic specificities have been identified in extracts of plant tumor induced in datura stramonium by agrobacterium tumefaciens. auxin oxidase and peroxidase activities are demonstrated for both enzymes. the adaptation of an immunochemical method allows the quantitative evaluation of both enzymes in different plant tissue extracts. the amount of these enzymes which is low in the organ of the healthy plant increases during tumorisation, healing and in vitro cult ... | 1971 | 11945769 | |
| promotion of crown-gall tumor growth by lysopine, octopine, nopaline, and carnosine. | the growth of crown-gall tumors on primary bean leaves (phaseolus vulgaris l. cv. "pinto") was promoted by the addition of d-lysopine, d-octopine, l-carnosine, or nopaline. assayed on tumors induced by agrobacterium tumefaciens strain b6, the relative activity was octopine = carnosine > lysopine >> nopaline; assayed on tumors induced by a. tumefaciens strain t-37, which induces tumors which form nopaline, the relative activity was nopaline = octopine = carnosine > lysopine. from one to three app ... | 1972 | 16657911 |

| isolation of morphological mutants of agrobacterium tumefaciens. | morphological mutants were isolated from a wild strain of agrobacterium tumefaciens at a high frequency by treatment with a nitrosoguanidine. seventeen of the 20 mutants isolated were temperature-sensitive. at 27 c, the mutant cells were rod-shaped and at 37 c, spherical or branched, whereas the wild-type cells were rod-shaped at both temperatures. | 1972 | 4553841 |
| transfection in agrobacterium tumefaciens. | intact cells of agrobacterium tumefaciens were examined for ability to take up biologically active lr-4 phage deoxyribonucleic acid (dna) from the surrounding medium. dna incorporation as measured by subsequent plaque formation (transfection) failed to occur when the bacteria were grown in defined minimal salts media, and was restricted to a 4-hr period in the early log phase of growth in enriched media. in the latter case, maximal transfection frequencies were obtained after a 25- to 30-min inc ... | 1972 | 5040385 |

| control of pantothenate accumulation in agrobacterium tumefaciens. | two pantothenate-requiring mutants of agrobacterium tumefaciens have been isolated. one of them (strain wmp-1) is unusual in that growth levels equivalent to the parent strain are achieved only when the medium is additionally supplemented with aspartate or another compound related to the tricarboxylic acid cycle. extracts of cells grown on limiting aspartate were found to contain four times more (14)c-pantothenate than those grown at optimal aspartate concentrations. this difference was found in ... | 1973 | 4347924 |
| transmissible resistance to penicillin g, neomycin, and chloramphenicol in rhizobium japonicum. | the genetic basis for resistance to a number of antibiotics was examined in rhizobium japonicum. resistance to penicillin g, neomycin, and chloramphenicol appears to be mediated by an extrachromosomal element similar to that found in the enterobacteriaceae. resistance to these antibiotics was eliminated from cells by treatment with acridine orange, and resistance to all three antibiotics could be transferred en bloc to agrobacterium tumefaciens under conditions excluding transformation or transd ... | 1973 | 4491197 |
