Chlamydomonas reinhardtii strains expressing nitrate reductase under control of the cabII-1 promoter: isolation of chlorate resistant mutants and identification of new loci for nitrate assimilation.

Abstract excerpt

The Chlamydomonas reinhardtii strain Tx11-8 is a transgenic alga that bears the nitrate reductase gene (Nia1) under control of the CabII-1 gene promoter (CabII-1-Nia1). Approximately nine copies of the chimeric CabII-1-Nia1 gene were found to be integrated in this strain and to confer a phenotype of chlorate sensitivity in the presence of ammonium. We have used this strain for the isolation of spontaneous...
