Novel metabolism in Chlamydomonas through the lens of genomics

Chlamydomonas has traditionally been exploited as an organism that is associated with sophisticated physiological, genetic and molecular analyses, all of which have been used to elucidate several biological processes, especially photosynthesis and flagella function and assembly. Recently, the genomics of Chlamydomonas has been combined with other technologies to unveil new aspects of metabolism, including inorganic carbon utilization, anaerobic fermentation, the suite and functions of selenoproteins, and the regulation of vitamin biosynthesis. These initial findings represent the first glimpse through a genomic window onto the highly complex metabolisms that characterize a unicellular, photosynthetic eukaryote that has maintained both plant-like and animal-like characteristics over evolutionary time.
