Some bacteriophages active against Rhizobium trifolii strain W19.
Fourteen soil bacteriophages active against Rhizobium trifolii W19 have been studied which fall into four structural groups. Group 1 phages have contractile tails. Some particles show double base plates to which at least three spikes are attached, and fibers are attached to the base plates. Group 2 phages also have contractile tails. At least five spikes are attached to the base plate, and ther...
متن کاملThe dynamic response of cellular carbohydrates to a NaCl shock in Rhizobium leguminosarum biovar trifolii TA-
The dynamic response of cellular carbohydrates to a NaCl shock in Rhizobium leguminosarum biovar trifolii TA1 (0.25 M-NaCI) and Rhizobium meliloti SU-47 (0.4 M-NaCl) grown in NaC1-free medium was investigated in nongrowing cell cultures and in cell suspensions, using in vivo NMR. After transferring cells grown in a NaC1-free medium to a glutamic-acid-free medium containing mannitol and NaCI, bo...
متن کاملConstruction of a Symbiotically Effective Strain of Rhizobium leguminosarum bv. trifolii with Increased Nodulation Competitiveness.
Genes involved in nodulation competitiveness (tfx) were inserted by marker exchange into the genome of the effective strain Rhizobium leguminosarum bv. trifolii TA1. Isogenic strains of TA1 were constructed which differed only in their ability to produce trifolitoxin, an antirhizobial peptide. Trifolitoxin production by the ineffective strain R. leguminosarum bv. trifolii T24 limited nodulation...
متن کاملGenome sequence of the clover symbiont Rhizobium leguminosarum bv. trifolii strain CC275e
Rhizobium leguminosarum bv. trifolii strain CC275e is a highly effective, N2-fixing microsymbiont of white clover (Trifolium repens L.). The bacterium has been widely used in both Australia and New Zealand as a clover seed inoculant and, as such, has delivered the equivalent of millions of dollars of nitrogen into these pastoral systems. R. leguminosarum strain CC275e is a rod-shaped, motile, G...
متن کاملGenome sequence of the Trifolium rueppellianum -nodulating Rhizobium leguminosarum bv. trifolii strain WSM2012.
Rhizobium leguminosarum bv. trifolii WSM2012 (syn. MAR1468) is an aerobic, motile, Gram-negative, non-spore-forming rod that was isolated from an ineffective root nodule recovered from the roots of the annual clover Trifolium rueppellianum Fresen growing in Ethiopia. WSM2012 has a narrow, specialized host range for N2-fixation. Here we describe the features of R. leguminosarum bv. trifolii stra...
