A Negative Regulator of Carotenogenesis in Blakeslea trispora.

ABSTRACT: As an ideal carotenoid producer, Blakeslea trispora has gained much attention due to its large biomass and high production of β-carotene and lycopene. However, carotenogenesis regulation in B. trispora still needs to be clarified, as few investigations have been conducted at the molecular level in B. trispora In this study, a gene homologous to carotenogenesis regulatory gene (crgA) was cloned from the mating type (-) of B. trispora, and the deduced CrgA protein was analyzed for its primary structure and domains. To clarify the crgA-mediated regulation in B. trispora, we used the strategies of gene knockout and complementation to investigate the effect of crgA expression on the phenotype of B. trispora In contrast to the wild-t
