Mechanisms regulating legume root nodule development are still poorly understood, and very few regulatory genes have been cloned and characterized. Here, we describe EFD (for ethylene response factor required for nodule differentiation), a gene that

In specific plant organs, namely the root nodules of alfalfa, fixed nitrogen (ammonia) produced by the symbiotic partner Sinorhizobium meliloti supports the growth of the host plant in nitrogen-depleted environment. Here, we report that a derivative

International audience; 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 in

International audience; A gene bank of Azospirillum lipoferum Br17 constructed in the vector lambda GEM11 was screened with a Bradyrhizobium japonicum nifA gene probe. A 7.3 kb EcoRI fragment carrying a nifA-like gene was thereby isolated and subsequ
