Abstract
Medicago truncatula, a relative of alfalfa (Medicago sativa), has been proposed as a model plant system for study of its interaction with th e symbiont Rhizobium meliloti. Differences in M. truncatula and alfalf a may result in distinct symbiosis behaviors for the two hosts when in association with wild-type or mutant bacterial strains. We have found that M. truncatula has a more stringent requirement for syrM and nodD 3 than is seen in alfalfa, In particular, the lack of syrM is associat ed with arrested nodule development.
