abstract |
The present invention also describes the DNA sequence for eukaryotic genes encoding ε cyclase, isopentenyl pyrophosphate isomerase and β-carotene hydroxylase as well as vectors containing the same and hosts transformed with said vectors. The present invention provides methods for controlling the ratio of various carotenoids in a host and for the production of novel carotenoid pigments. The present invention also provides a method for screening for eukaryotic genes encoding carotenoid biosynthesis. |
