De-epoxidation state (DES) determined as Dtx/(Dtx + Ddx), relative level of the pool of xanthophyll (Dtx + Ddx) normalized to the fucoxanthin (Fux) content a, non-photochemical quenching (NPQ) kinetics b of wild-type (Pt1 and/or Pt6) and eight VDL1 overexpression (OE) strains grown under low light (60 μmol photons m−2·s−1). Allele 1 and allele 2 represent the VDL1 alleles 1 and 2, respectively. Ddx: diadinoxanthin, Dtx: diatoxanthin. Different letters above the bars indicate statistically significant differences (P < 0.01)
