Validated Nuclear-Based Transgene Expression Regulated by the Fea1 Iron-Responsive Promoter in the Green Alga Chlamydomonas reinhardtii.

Microalgae are in the focus for the production of recombinant proteins in research and potential commercial application. Inducible promoters represent important tools that potentially allow the expression of recombinant proteins at higher rates. In general, they are used to separate the culture growth phase from the production phase by initiating product formation after high cell densities have been achieved.
