Changes in the levels of photosynthetic proteins during dehydration. A, Stained gel of thylakoid membrane fractions (3 µg of protein per lane) isolated from plants at 100%, 40% to 50%, and 15% to 20% RWC. Arrowheads mark the major LHCII bands. B, Representative immunoblots of thylakoid fractions probed against the PSII core protein D1, OEC33, the cytochrome f subunit of the cytochrome b₆f complex, the PsaA core protein of PSI, and the Lhcb1 subunit of LHCII. C, Quantification of changes in the levels of the different thylakoid proteins shown in B during dehydration. Bars shown represent means ± se from at least three independent experiments.
