06.407 - Spontaneous Nodulation Factor Snf2
Patent Reference: International Patent Publication No. WO2008/009287. EP Patent No. 2,044,201.
Professor Jens Stougaard
Aarhus University (Denmark)
Researchers at the University of Aarhus led by Prof Jens Stougaard have shown that specific mutations in a gene (Snf2) encoding a cytokinin-independent histidine kinase in the model legume Lotus japonicus cause spontaneous root nodule formation in the absence of nitrogen-fixing Rhizobium species and/or their produced nodulation factors. Expression of such mutant genes may potentially be useful as a tool for establishing nitrogen-fixing Rhizobium interactions in non-nodulating plants such as cereals and for providing increased/improved nodulation in legumes.
