purification and some properties of a non-haem iron protein from the bacteroids of soya-bean (glycine max merr) nodules.a non-haem iron protein was isolated from an extract of soya-bean nodule bacteroids by a procedure including protamine sulphate and heat precipitation followed by chromatography on deae-cellulose. the purified protein contains non-haem iron and acid-labile sulphur and exhibits a spectrum with a rather broad absorption shoulder in the region 380-440nm and a more prominent peak at 280nm. from sedimentation-velocity measurements an apparent s(20,w) value of 1.3s was calculated. the protein function ...19705529239

agrobacterium tumefaciens ribonucleic acid synthesis in tomato cells and crown gall induction.purified agrobacterium tumefaciens deoxyribonucleic acid (dna) does not produce crown gall tumors in growing plants, conditioned by wounding, as the living bacteria do. purified bacterial dna migrates in the plant and replicates, but it is not transcribed in our experimental conditions. on the contrary, when dna is released naturally from bacteria into plant cells, a bacterial ribonucleic acid (rna) can be found in these cells. there seems to be a direct relation between the appearance of a. tum ...19715573736

agrobacterium tumefaciens conn. iv. bacteriophage pb21 and its inhibitory effect on tumor induction.strain b2 of agrobacterium tumefaciens conn produces plaques when seeded against strain b6-806 of the same organism. from such a plaque, a highly virulent bacteriophage was obtained by use of d'herelle's technique of selecting for virulent phage. on nutrient agar, this phage, pb2(1), produced large clear plaques which did not overgrow. plaques produced on a glutamate medium and on white's plant tissue culture medium were even larger and in white's medium had a three-dimensional appearance. pb2(1 ...19675623963

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 ...19685643064
thermostability of antigens associated with serotype of rhizobium japonicum.the antigens associated with serologically distinct strains of rhizobium japonicum were found to differ in heat sensitivity. cell preparations from 4 out of 12 strains retained agglutinability, and 1 out of 5 retained antigenicity after they were heated to 120 c. antigenicity was reduced in most strains after heating to 100 c for 30 min, but agglutinability was not affected by this treatment. this suggests that the antigens are protein-polysaccharide-lipid complexes described for o-type antigens ...19685645406

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 ...19685669890

populations of dalapon-decomposing bacteria in soil as influenced by additions of dalapon or other carbon sources.the numbers of bacteria capable of decomposing the herbicide dalapon were determined for five soils by the most-probable-number method. before treatment of the soils with dalapon, the numbers varied from 1,000 to 10,000 cells per g of soil. incubation of the soils with dalapon resulted in large increases (100-fold) in two of three soils in which dalapon was decomposed rapidly. lack of increase in numbers in spite of rapid decomposition in the other soil probably indicated breakdown by a chemical ...19695772393
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 ...19695773014
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 ...19695774138
glucose catabolism in rhizobium japonicum.glucose catabolism in rhizobium japonicum atcc 10324 was investigated by the radiorespirometric method and by assaying for key enzymes of the major energy-yielding pathways. specifically labeled glucose gave the following results for resting cells, with values expressed as per cent (14)co(2) evolution: c-1=59%, c-2=51%, c-3=45%, c-4=59%, and c-6=43%. these values indicate that glucose was degraded by the entner-doudoroff pathway alone. cells which grew in glucose-yeast extract-salts medium gave ...19695776525
b12 coenzyme-dependent ribonucleotide reductase in rhizobium species and the effects of cobalt deficiency on the activity of the enzyme.this investigation revealed that the ribonucleotide reductases in extracts of rhizobium leguminosarum, r. trifolii, r. phaseoli, r. japonicum, and r. meliloti 3doal (ineffective in nitrogen fixation) are dependent upon b(12) coenzyme for activity. rhizobium and certain lactobacillus species are the only two groups of organisms known to contain b(12) coenzyme-dependent ribonucleotide reductases. extracts of cobalt-deficient r. meliloti cells assayed in the presence of optimum b(12) coenzyme showe ...19695780513

tumor growth complementation among strains of agrobacterium.the ability of 31 strains of agrobacterium to initiate the production of a tumor growth factor (tgf) which is associated with crown-gall tumors on primary pinto bean leaves was determined. extracts from bean leaves inoculated with these bacteria were tested and they showed that 16 of the 19 strains that induced tumors on the leaves also initiated tgf production. the three strains for which no tgf was detected were of low infectivity and included two strains of a. tumefaciens and a strain of a. r ...19695808077
