Abstract

The present invention describes the DNA sequence for eukaryotic genes encoding &egr; cyclase, isopentenyl pyrophosphate (IPP) isomerase and &bgr;-carotene hydroxylase as well as vectors containing the same and host cells transformed with said vectors. The &egr; cyclase and &bgr;-carotene hydroxylase genes disclosed include those from A. thaliana; the IPP isomerase genes disclosed include those from A. thaliana, H. pluvialis, and marigold. The present invention also provides methods for controlling the ratio of various carotenoids in a host cell and for the production of novel carotenoid pigments. The present invention also provides a method for screening for eukaryotic genes encoding carotenoid biosynthesis enzymes.
