Beschreibung
Zusammenfassung:	Mutant photosynthetic microorganisms having reduced chlorophyll and increased photosynthetic efficiency are provided. The mutant strains have mutated chloroplastic SRP54 genes and exhibit increased productivity with respect to wild type strains. Also provided are mutant algal strains having mutated cytosolic SRP54 genes. Provided herein are methods of producing biomass and other products such as lipids using strains having mutations in an SRP54 gene. Also included are constructs and methods for attenuating or disrupting SRP54 genes.
