05.372 - Sponteneous Nodule Factor Snf1
Patent Reference: International Patent Publication Number WO2007/006318
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 (Snf1) encoding a calcium/calmodulin dependent protein 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.
