Rhizobium spp. are found in soil. They are both free-living and found symbiotically associated with the nodules of leguminous plants. Traditionally, studies have focused on the association of these organisms with plants in nitrogen-fixing nodules, since this is regarded as the most important role of these bacteria in the environment. Rhizobium sp. are known to possess several replicons. Some, like the Rhizobium etli symbiotic plasmid p42d and the plasmid pNGR234b of Rhizobium NGR234, have been sequenced and characterized. The plasmids from these organisms are the focus of this short review.

Study on the isolation and identifications of bacteria associated with the root of legumes were conducted using Spread Plate Technique. The frequencies of occurrences of the bacteria isolate showed that a total of sixteen (16) bacteria belonging to three genera and four species were isolated from the leguminous plants. Maximum number recovered from sample collected from the root of groundnut was seven (7) followed by Soya bean with five (5) while Pea recorded the least number of four (4). Role of Bacillus subtilis in the soil around the leguminous plant was the highest, which covered about 37.50% of the total isolates. Other bacteria that were also isolated from the soil around the legumes root include Bacillus cereus and Staphylococcus aureus which covered about four (4) each representing 25.0% of the total isolates while Pseudomonas aeruginosa recorded the least value of 12.50%. The bacteria isolated from the root of the legumes were not significantly different (P < 0.05). The bacteria have Nitrogen-fixing potential, having isolated from three leguminous plants which include Soya bean, Groundnut and Pea.

The influence of crop rotation and wheather conditions on the <i>Fusarium</i> population in soil and on <i>Fusarium</i> wilt of flax was examined in the Institute of Native Natural Fibres in 1968-1975. The experiments were carried out in various regions of flax planting in Poland during 8 years. Crop rotation had a significant influence on the process of biological soil disinfestation. <i>Fusarium</i> population in soil increased after planting flax, wheat, barley and sugar-beet, and decreased or did not change after rape, hemp, potato and leguminous plants. The crop rotation significantly influenced the composition of the <i>Fusarium</i> population as far as species are concerned. The highest wilt infection of flax was found in plantings after flax, sugarbeet and wheat and the weakest in plantings after rape. A six-year crop rotation was sufficient to eliminate the wilt pathogen from infested soil. But on flax-sick soil the process of biological disinfestation proceeded more slowly and a seven-year interval between flax crops was too short.
