Diurnal changes in DES, NPQ, and LHCX1 transcript (A), and LHCX protein levels (B). Cells were exposed to a 12:12 h light:dark regime at 70 μmol photons m⁻²·s⁻¹, and samples were collected at the indicated times during the light phase for the different measurements. Error bars refer to duplicate measurements in three biological samples. NPQ, DES, and blot analyses were performed as specified in Fig. 1.
