Abstract

The zygomycete Blakeslea trispora is an important strain for the production of carotenoids on a large scale. However, the regulation mechanism of carotenoid biosynthesis is still not well understood in this filamentous fungus. In the present study, we sought to investigate how crgA influences the expression of structural genes for carotenoids, carotenoid biosynthesis, and other anabolic phenotypes. This will lead to a better understanding of the global regulation mechanism of carotenoid biosynthesis and facilitate engineering this strain in the future for enhanced production of carotenoids.
