Time-resolved fluorescence analysis of P. tricornutum cells adapted to LL. A and B, DAS for wild-type (WT) cells upon a 400-nm excitation (A) and a 540-nm excitation (B) in unquenched (unq; solid lines) and quenched (q; dotted lines) states. C and D, DAS for lhcx1 cells upon a 400-nm excitation (C) and a 540-nm excitation (D) in unquenched and quenched states. Measurements were performed at 77 K. DAS were calculated as explained in “Materials and Methods”. a.u., arbitrary units.
