Title
The evolution of symbiont preference traits in the model legume Medicago truncatula

Other claims from this paper (5)
- Observation M. truncatula is an efficient root forager.
- Observation M. truncatula forms more nodules with the effective Ensifer meliloti rhizobium than with the ineffective strain.
- Association Root biomass in M. truncatula increases with the number of effective nodules but not with the number of ineffective nodules.
- Association Root foraging is not genetically correlated with either preferential allocation or preferential association in M. truncatula.
- Mechanism The authors suggest that preference traits probably evolve to take better advantage of effective symbionts rather than to exclude ineffective partners.
