Functional Analysis of Carotenoid Biosynthetic Genes and Pathway of the Filamentous Anoxygenic Phototrophic Bacterium Chloroflexus aurantiacus
Background/Objectives: Carotenoids play essential roles in light harvesting, photoprotection, and oxidative stress defense in photosynthetic organisms. The filamentous anoxygenic phototroph Chloroflexus aurantiacus synthesizes diverse carotenoids; however, the biosynthetic basis and regulation of these pigments are unc...
