Mutant strains of clover rhizobium (Rhizobium trifolii) that form nodules on soybean (Glycine max).
Mutant strains of Rhizobium trifolii that induce nitrogenase activity in the free-living state were isolated. These strains, unlike the wild type, nodulated soybean and mungbean plants, producing effective nodules. One of the strains, strain DT72, also nodulated clover but the nodules were ineffective. Strain DT125 consumed hydrogen gas from the gas phase, which can be coupled to nitrogenase ac...
متن کاملSOME F>iCTORS AFFECTING THE SURVIVAL OF RHIZOBIUM
Survival of Rhizobium trifolii on white clover seed before sowing is adversely affected by both drying and a water-soluble toxin which di f fuses f rom the seed coat dur ing the inocula t ion process . Survival of rhizobia is increased by removal of the toxin by seed washing or the suppress ion of i t s inhib i tory ef fec t by t rea tment of seed wi th phenol ic adsorbents . Surv iva l o f rh ...
متن کاملFactors affecting white clover persistence in New Zealand pastures
Better persistence and reliability of white clover (Trifolium repens L.) is critical in achieving a more competitive New Zealand farming industry. To persist, white clover must establish well and withstand the accumulated stresses of competition from associated grasses, grazing, variable soil fertility, drought, plus pest and disease pressure. These factors vary markedly with environment and fa...
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 clover-nodulating Rhizobium leguminosarum bv. trifolii strain SRDI943.
Rhizobium leguminosarum bv. trifolii SRDI943 (strain syn. V2-2) is an aerobic, motile, Gram-negative, non-spore-forming rod that was isolated from a root nodule of Trifolium michelianum Savi cv. Paradana that had been grown in soil collected from a mixed pasture in Victoria, Australia. This isolate was found to have a broad clover host range but was sub-optimal for nitrogen fixation with T. sub...
