b DNA molecule that encodes a histidine kinase polipeptu00ecdeo of mutant and its use in connection, polipeptu00ecdeo of histidine kinase mutant, as well as the production method of a genetically modified plant d .The present invention relates to the formation of root nodules in legumes, nitrogen fixing, which is induced by the capture of signaling molecules of oligosaccharides of lipoquitina secreted by bacteria Rhizobium compatible, which trigger a via simbiu00f3tu00edca common.The present invention provides a mutant of spontaneous formation of nodule (SNF2), in which the formation of nodules synbiotics is spontaneous, leading to the development of nodular graphite in the absence and in the presence of bacteria Rhizobium and / or signs rizobiais exogenous.The invention also provides an isolated DNA sequence which encodes a histidine kinase mutant independent interactions, whose activity results in the dominant phenotype 'gain of function' of the spontaneous formation of the node.In addition, it is shown that the SNF2 gene confers a phenotype characterized by spontaneous nodule organogenesis is regulated in plants that have a genetic background to nodulate deficient.A gene of the invention, conferring this phenotype to nodulate spontaneous, has utility for the transfer and establishment of the ability of nitrogen fixation in plants not noduladas, and thereby reduces the dependence of nitrogenous fertilizer of crops for non nod Uladas.
