Representative Mn SEC-ICP-QQQ-MS chromatograms (raw data) of thylakoids isolated from control (Ctrl) plants or plants exposed to mild, moderate, or severe Mn deficiency for the Mn-inefficient genotype cv Antonia (A) and Mn-efficient genotype cv Vanessa (B). Fractionated PSII complexes were indexed as follows: PSII-LHCII supercomplex (SC), dimer (D), and monomer (M). Mn bound in PSII (C) and total leaf Mn concentration (youngest fully emerged leaves; D). Values are means ± se (n = 3). Bars with the same letter are not significantly different (P ≥ 0.05). DW, Dry weight.
