Responses of the Medicago truncatula-Sinorhizobium interaction to variation in N2-fixation of the bacterial partner were investigated. Split-root systems were used to discriminate between local responses, at the site of interaction with bacteria, and systemic responses related to the whole plant N status. The lack of N acquisition by a half-root system nodulated with a nonfixing rhizobium triggers a compensatory response enabling the other half-root system nodulated with N2-fixing partners to compensate the local N limitation.This response is mediated by a stimulation of nodule development (number and size) and involves a systemic signaling mechanism related to the plant N demand. In roots co-infected with poorly and highly efficient strain...
