Figure Lengend Snippet: Phosphothreonine-immunoblot of thylakoid proteins isolated from Arabidopsis leaves after four different treatments : Control (Ctr), Cold/Light (C/L), Dark (D) and Cold/Dark (C/D). Below the immunoblot, 77 K fluorescence emission ratios (F732/F685 ± S.D.) of thylakoids from differentially treated plants are given. F732 stands for the fluorescence peak at 732 nm representing the emission from PSI and F685 for the fluorescence peak at 685 nm from PSII. Differences in F732/F685 ratios are related to reversible phosphorylation of the light-harvesting chl a/b proteins (LHCII) and their attachment with PSI (phosphorylated, high ratio) and PSII (non-phosphorylated, low ratio). P-CP43, P-D2, P-D1 denote the phosphorylated proteins of PSII core, P-LHCII denote the LHCII phosphoproteins.

Figure Lengend Snippet: Verification of some microarray results using northern blot analysis after four different treatments: Control (Ctr), Cold/Light (C/L), Cold/Dark (C/D) and Dark (D) . Hybridizations were made with genes encoding: four photosystem II light harvesting proteins (LHCB) and the Early Light Inducible Protein (ELIP1); two photosystem I related (PSI) proteins, PSI-N and plastocyanin (PC); two proteins of carbohydrate metabolism, a plastidic fructose bisphoshate aldolase (Pl-FBA) and a pyruvate decarboxylase (PDC1); a ZEP protein involved in zeaxanthin and ABA biosynthesis; four chloroplast targeted proteins involved in oxygen radical scavenging and three cytoplasmic or peroxisomal catalases (CAT); a cold-responsive protein (LTI78/RD29A) and genes encoding a MYB-like (CCA1) and three AP2 transcription factors. The hybridization of the 16S rRNA probe to total RNA is shown in the bottom of the figure.

Figure Lengend Snippet: Western blot analysis of dehydrin proteins (A) and of LHCB and glutathione reductase proteins (B) . Protein samples isolated from Arabidopsis leaves under growth condition (Ctr), after the Cold/Light (C/L) treatment, subsequent recovery for one hour at normal growth conditions (re-1hL), after 8-hour Darkness (D) and after the Cold/Dark (C/D) treatment. A typical result is presented out of three independent western blot experiments.
