摘要

The multiplication of Chlamydomonas reinhardtii wild type cells can be arrested by the spirolactone RU 26752 and this is fully reversible by the natural mineralocorticoid aldosterone. Evidence is presented for a 52 kDa protein that possesses functional DNA and ligand binding domains and tests positive for mineralocorticoid receptor-like activity by immuneprecipitation, macroaggregation, and photoaffinity. The regulation of trans-activation by steroid hormones in the animal world would therefore appear to be just as valid for the plant kingdom, thereby providing a new model for genetic analysis.
