  • Substance with lipo-oligosaccharide structure capable of acting as plant-specific symbiotic signals, processes for producing them and their applications
    Patent number: 5549718
    Abstract: An essentially pure substance has a structure of a Nod factor or one of its analogues. The Nod factor is characterized by the fact that its biosynthesis is controlled by at least one nodulation gene (nodA,B,C) common to the Rhizobiaceae, in particular to the genera Rhizobium, Bradyrhizobium, Sinorhizobium and Azorhizobium. This substance consists of a lipo-oligosaccharide which is not a derivative of the exopolysaccharides and which has the general formula (I). In formula (I), the Nod factor of which it has the structure is a plant-specific symbiotic signal and is capable of enhancing the capacity of the bacteria of infect the host plant with which it is associated and/or of accelerating the formation of nodules on the host plant with which it is associated and/or of inducing the transcription of symbiotic genes of the leguminoseae. Applications to the treatment of plants and as an active therapeutic agent in humans and animals.
