Other claims from this paper (11)
- Observation Dry and mucoid isolates retained stable colony phenotypes through subculturing.
- Observation The isolates were most closely related to S. meliloti by partial 16S rRNA sequencing.
- Observation All isolates produced at least one of three exopolysaccharides needed for Medicago nodulation.
- Observation WSM826 isolates probably produce succinoglycan.
- Association Loss of mucoidy was not associated with an expR insertion sequence in dry isolates of either strain.
- Observation WSM688 dry and mucoid isolates had identical PCR fingerprints.
- Observation WSM688 dry and mucoid isolates had similar nodulation and nitrogen fixation capacity with M. truncatula.
- Observation WSM826 mucoid isolates had different PCR fingerprints from one another and from dry isolates.
- Intervention effect Inoculation with WSM826 isolate 826-3 significantly lowered shoot dry weight of M. sativa.
- Observation WSM826 isolate 826-3 retained capacity to nodulate both Medicago hosts.
- Mechanism Reduced shoot weight suggests WSM826 isolate 826-3 had impaired nitrogen fixation capacity.
