Estimated number of xanthophylls in native LHCII complexes isolated from shade (A), shadeL (B), and sun leaves (C) of I. sapindoides. Band 3 from the Suc density gradient was isolated by a mild (0.6% α-DM) and a more stringent (1.0% β-DM) detergent treatment to identify the loosely bound xanthophylls in the peripheral V1 site, which are represented by the difference between the samples isolated with α- and β-DM (α−β). Xanthophyll levels are given per monomer assuming 14 and 12 Chl molecules per monomer of the trimeric LHCII complex isolated with α- and β-DM, respectively.
