Expression patterns of genes encoding photosynthesis-associated proteins and photoreceptors after dark treatment and re-exposure to white light.

<p>The differentially regulated genes include antenna proteins, components involved in oxidative photosynthesis and photoreceptors after dark treatment for 48 h (D48) and re-exposure to white light (WL) for 0.5, 6 and 24 h. Continuous white light (CWL) were control conditions. The color code indicates expression values, and squares with a diagonal line inside indicate genes with an expression ratio (log₂ transformed) greater than +/−0.5 that are not significantly regulated. Genes where at least one of the two probes used for calculation of the expression ratios were significantly regulated by >2-fold at least at one time point during the experimental period were included in the figure. The expression patterns of genes marked with an asterisk indicate that they are chloroplast-encoded, and that the expression ratios was assessed by qRT-PCR instead of microarray analyses. The nuclear-encoded LHC48798 gene was not represented on the microarray, and were therefore also assessed by qRT-PCR analyses. The scale on the right represents gene expression ratio values, log₂ transformed. The abbreviations used are LHCF: major fucoxanthin Chl a/c proteins; LHCR: red algal-like proteins; LHCX: LI818-like proteins; LHCZ: unknown function antenna protein, LHC#: unclassified light harvesting proteins, numbers refer to protein ID in JGI; LHL: Lhc-like; Psa: PSI proteins; Psb: PSII proteins; PETB-C: cytochrome b6f complex proteins; PETH: Ferredoxin-NADP reductase; PETJ: cytochrome c6; Atp: F-ATPase proteins; AUR: aureochrome; PAS: PER-ARNT-SIM domain, probably aureochrome; CRYL: cryptochrome-like protein; CPF: cryptochrome/photolyase family protein; SKP3: Sensor Kinase Protein 3.
