Patent number: 8629323Abstract: The invention provides isolated and at least partially-purified dicamba-degrading enzymes, isolated DNA molecules coding for dicamba-degrading enzymes, DNA constructs coding for dicamba-degrading enzymes, transgenic host cells comprising DNA coding for dicamba-degrading enzymes, and transgenic plants and plant parts comprising one or more cells comprising DNA coding for dicamba-degrading enzymes. Expression of the dicamba-degrading enzymes results in the production of dicamba-degrading organisms, including dicamba-tolerant plants. Finally, the invention provides a method of selecting transformed plants and plant cells based on dicamba tolerance and a method of selecting or screening transformed host cells, intact organisms and parts of organisms based on the fluorescence of 3,6-dichlorosalicylic acid produced as a result of dicamba degradation.Type: GrantFiled: January 12, 2012Date of Patent: January 14, 2014Assignee: Board of Regents of the University of NebraskaInventors: Donald P.

Publication number: 20030157583Abstract: The cloning of a truncated Arabidopsis gene expressing squalene synthase, as well as the expression and purification of the squalene synthase, are described. Also described herein is a fluorescent assay using squalene synthase that is amenable to high-throughout use, particularly for studying the regulation of isoprenoid synthesis and identifying squalene synthase inhibitors and promoters. As the formation of squalene is stoichiometric with the depletion of NADPH, the activity of squalene synthase can be evaluated by following the NADPH concentration over time. Squalene synthase activity is determined by combining FPP, NADPH, squalene synthase and a magnesium ion cofactor to form a reaction mixture under conditions suitable for squalene formation, optionally in the presence of a compound being analyzed for its ability to inhibit or promote squalene synthase. The concentration of NADPH over time is determined by subjecting the reaction mixture to UV light and detecting fluorescent light emission.Type: ApplicationFiled: December 17, 2001Publication date: August 21, 2003Inventors: Donna Stevens, Xiao-Zhuo Wang, John Rice, Beth Nye, David Broadwell, Norman Glassbrook, Veeresh Sevala, John Crawford, Sandy Stewart
