Other claims from this paper (5)
- Association Hosts with shorter nodules were more selective of rhizobial strains.
- Observation A genome-wide association study on host selectivity identified genes including leginsulin, pectin degradation and multidrug and toxic compound efflux.
- Observation A genome-wide association study on host selectivity identified genes for zinc transport and DNA methylation.
- Association Both Medicago hosts enriched beneficial rhizobial strains in large nodules compared with small nodules.
- Association The Medicago host forming larger and more variably sized nodules was less effective for rhizobial populations.
