Brief Description:
This patent describes the first ever identification of the three genes underlying resistance to Soybean Cyst Nematode and Sudden Death Syndrome at the rhg1 and Rfs2 locus both located on linkage group G, chromosome 18. They include a receptor like kinase a laccase and a transporter. The genes can be used with other technologies like transgenic SCN resistances or the loci Rhg2-8 or Rfs1, 3-12. Having the gene for resistance has the added benefit of enabling a reduction of the yield penalty from resistance that is derived from rhg1s negative effects on germination and root growth.
Patent Status:
Patent pending. U.S. patent application no. 20020144310, published October 3, 2002.
Potential Commercial Uses:
This may have multiple commercial advantages including:
- Use of the genes for plant transformation.
- Use of the genes for creating an assay kit for detecting SCN/SDS resistance.
- Accurate and fast genetic marker selection.
- Molecular probes, positional cloning, and related uses.
