Nitrates 92-99 uncharacterized protein Chlamydomonas reinhardtii 0-4 20449593-8 2010 HSF1 levels recovered partly when transformant cells were shifted back to ammonium for 72 h. Transformants developed thermosensitivity only on nitrate and thermosensitivity correlated with strong reduction in HSF1 levels, hence supporting our earlier conclusion that HSF1 is a key regulator for thermotolerance in Chlamydomonas. Nitrates 143-150 uncharacterized protein Chlamydomonas reinhardtii 0-4
