Information is virtually lacking on the symbiotic properties of indigenous populations of rhizobia and their capacity to nodulate and fix nitrogen when in symbiosis with locally-adapted cultivars of Phaseolus and other legume species grown in southern Texas.
For this reason, PCR-RFLP analyses of symbiotic and genomic genes were used to determine the taxonomic position of twenty-one of the rhizobial strains able to nodulate P.
In addition, other isolates able to nodulate bean show distinct phylogenetic positions and may well represent other species (Eardly 1992).
More importantly, inability to nodulate did not affect growth and diameter of the plant stems.
In addition, the Groundnut varieties (ALR1 and 2) did not nodulate in this soil.
laciniata were shown to preferentially nodulate
This role of lectins is supported by the ability of a pea-specific Rhizobium strain to effectively nodulate
white clover, following introduction of the pea lectin gene into clover roots (Diaz et al.

Bacteria and Guar (Cyamopsis teragonolaba L.
The 11 putative rhizobial strains and 2 commercial inoculant strains were examined for their ability to nodulate and fix nitrogen with 3 subterranean clover cultivars (Dalkeith, Trikkala, and Gosse) (Expt 1).
All isolates were examined in parallel with the inoculant strains WU95 and TA1 for their ability to nodulate and fix nitrogen with 1 subterranean clover cultivar (Trikkala).
