Nonphotochemical quenching (NPQ). A, B Measurement of NPQ kinetics of UVM4 (black), bkt5 (red) and npq4 lhcsr1 (green, indicated as npq4.1) cells using actinic lights of 1200 μmol photons m−2 s−1. C, D NPQ values after 10 min of illumination with different actinic light intensities. Cells were adapted in control (CL left) of high light (HL right). Error bars are reported as standard deviation (n = 4). Values significantly different comparing bkt5 with UVM4 are reported with * (Student’s t test, P < 0.05)
