Regulation of carotenogenesis in the red yeast xanthophyllomyces dendrorhous: the role of the transcriptional co-repressor complex cyc8-tup1 involved in catabolic repression

Abstract

Background: The yeast Xanthophyllomyces dendrorhous produces carotenoids of commercial interest, including astaxanthin and beta-carotene. Although carotenogenesis in this yeast and the expression profiles of the genes controlling this pathway are known,
