摘要：
2055447 9113078 PCTABS00007 DNA segments encoding the Erwinia herbicola enzymes geranylgeranyl pyrophosphate (GGPP) synthase, phytoene synthase, phytoene dehydrogenase-4H, lycopene cyclase, beta-carotene hydroxylase, and zeaxanthin glycosylase and DNA variants thereof encoding an enzyme having substantially the same biologically activity, vectors containing those DNA segments, host cells containing the vectors and methods for producing those enzymes, a method for protecting plants from the herbicide norflurazon, as well as methods for producing GGPP and the carotenoids phytoene, lycopene, .beta.-carotene, zeaxanthin and zeaxanthin diglucoside by recombinant DNA technology in tranformed host organisms are disclosed.
