Phage-resistant and -susceptible bacteria from nodules of alfalfa and sweet clover, grown at a site without a known history of cultivation, were identified as diverse genotypes of Ensifer, Rhizobium and Phyllobacterium species based on sequence analy

Restriction fragment length polymorphism (RFLP) analysis was used to assess genetic variation in samples of two field populations of Sinorhizobium meliloti (from sites 2 km apart) that had been characterized on the basis of phage sensitivity. Restric

Insertion sequence (IS) hybridization was used to define the structure of a population of Rhirobium meliloti isolated directly from soil and from nodules of Medicago sativn (alfalfa) and Melilotus alba (sweet clover) grown under controlled conditions

Sixty-one isolates of Rhizobium meliloti from two field sites which had been previously classified into 15 phage types on the basis of sensitivity to 16 typing phages, were subjected to insertion sequence (IS) hybridization using DNA probes for ISRm3

A nutrient poor medium containing 100mg l −1 yeast-extract, 400 mg l −1 tryptone, 100mg l −1 calcium chloride, 150mg l −1 cycloheximide, 25 mg l −1 Congo-red and 10 g l −1 agar (medium A) greatly reduced polysaccharide production and perm

Populations of indigenous Rhizobium meliloti isolated from nodules of alfalfa grown at sites A and B (soil pH, 7.0 and 6.1, respectively) were previously characterized on the basis of phage sensitivity and divided into 55 and 65 phage types. The avai

Indigenous Rhizobium meliloti were previously characterized on the basis of plasmid profiles and phage sensitivity patterns (phage types). Rhizobium meliloti 1076, which contained two cryptic plasmids, was one of four isolates comprising phage type 2

The insertion sequence ISRm1 frequently occurs in Rhizobium meliloti and is a potential mutagen. Data for the frequency of ISRm1 transposition in the commercial inoculant strain SU47 (containing eight copies of IsRm1) indicate that this insertion seq

Thirty-three isolates of indigenous Rhizobium meliloti, either possessing cryptic plasmids that hybridize to probes for symbiotic genes or lacking a 1500-kb megaplasmid band in Eckhardt gels, were tested for infectivity on 10 legume species grown und
