Abstract: The invention provides recombinant algal organisms that have a genetic modification to a gene or nucleic acid sequence encoding an RNA binding domain. In some embodiments the genetic modification can be a functional deletion or attenuation of the gene. The genetic modification results in a mutant organism with increased lipid productivity and/or higher biomass productivity. The lipid products of these mutants can be utilized as biofuels or to manufacture other specialty products. The recombinant mutants can also, optionally, have a genetic modification to a gene encoding an SGI1 polypeptide. Methods of making and using the recombinant algal mutants and methods of producing lipids are also disclosed.

Abstract: The present application provides novel algal regulatory elements including inducible nitrate/nitrite promoter sequences and terminator sequences. The application further discloses DNA constructs comprising these novel regulatory elements, and recombinant microorganisms comprising these regulatory elements. Methods of modifying, producing, and using the regulatory elements are also disclosed. Methods disclosed in the present application are suited for inducible expressions of genes, such as a transgene or a native gene in algal species.
