WebJul 1, 2024 · The diadinoxanthin cycle (DD cycle), involving Diadino de-epoxidation and Diato epoxidation, seems to be the first defence mechanism because of high amount of pigments engaged and high rates of both reactions (Lohr and Wilhelm, 1999). A substrate of light-induced de-epoxidation – Diadino, is permanently present in diatom cells. WebJan 3, 2014 · The pool of photoprotective pigments (diadinoxanthin and dinoxanthin) and peridinin was not able to regulate the excessive light-absorption at high I0-T. OA synthesis in cells was decoupled from optimal growth conditions, as OA overproduction was observed at high temperatures and when both temperature and irradiance were low. T-flask culture ...
