CHICAGO — Chromatin Inc., Chicago, and Syngenta Biotechnology, Inc., Research Triangle Park, N.C., said June 26 they had entered into an exclusive global research and commercial license agreement giving Sygenta rights to use Chromatin’s proprietary gene stacking technology for trait genes in all members of the genus Saccharum, which includes commercial sugar cane and energy cane, and crosses with other plant species. New trait combinations in sugar cane are expected to provide improved production efficiency and yields. Chromatin developed a novel approach to gene stacking using the plant’s own DNA to deliver several genes. Syngenta obtained non-exclusive rights for use of the same technology in corn and soybeans in 2007.
