Abstract
Mutant photosynthetic algae having increased biomass productivity are provided. The mutants have attenuated expression of violaxanthin chlorophyll a binding proteins (VCP) or fucoxanthin chlorophyll a/c binding proteins (FCP), reduced chlorophyll, higher apparent ETR(II), little to no reduction in Pmax per cell, and decreased NPQ over a wide range of light intensities. Provided herein are constructs for attenuating or disrupting VCP or FCP genes. Also provided are methods of culturing VCP or FCP mutants for the production of biomass or other products.
