Title
(EN) GENES OF CAROTENOID BIOSYNTHESIS AND METABOLISM AND A SYSTEM FOR SCREENING FOR SUCH GENES
(FR) GENES DU CAROTENOIDE ET BIOSYNTHESE ET METABOLISME ET SYSTEME POUR DETECTER CES GENES
Abstract
(EN)
The present invention also describes the DNA sequence for eukaryotic genes encoding $g(e) cyclase, isopentenyl pyrophosphate isomerase and $g(b)-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 screeing for eukaryotic genes encoding carotenoid biosynthesis.

La présente invention décrit la séquence d'ADN pour des gènes eucaryotes codant l'$g(e) cyclase, l'isopentényle pyrophosphate isomérase et la $g(b)-carotène hydroxylase ainsi que les vecteurs contenant ces derniers et les hôtes transformés par ces vecteurs. La présente invention concerne des procédés pour moduler le rapport entre divers caroténoïdes chez un hôte et produire de nouveaux pigments caroténoïdes. La présente invention concerne également un procédé pour détecter des gènes eucaryotes codant la biosynthèse des caroténoïdes.
