Open AccessNatural genetic variation in GLK1-mediated photosynthetic acclimation in response to light
GOLDEN-like (GLK) transcription factors are central regulators of chloroplast biogenesis in Arabidopsis and other species. Findings from Arabidopsis show that these factors also contribute to photosynthetic ac...

Open AccessPGRL2 triggers degradation of PGR5 in the absence of PGRL1
In plants, inactivation of either of the thylakoid proteins PGR5 and PGRL1 impairs cyclic electron flow (CEF) around photosystem I. Because PGR5 is unstable in the absence of the redox-active PGRL1, but not vi...

Singlet Oxygen and Protochlorophyllide Detection in Arabidopsis thaliana
Since the recognition of the reactive oxygen species singlet oxygen (1O2) as a versatile signal that induces various stress responses, the mechanisms underlying 1O2-induced signaling transduction pathways have be...

Open AccessChloroplast development and genomes uncoupled signaling are independent of the RNA-directed DNA methylation pathway
The Arabidopsis genome is methylated in CG and non-CG (CHG, and CHH in which H stands for A, T, or C) sequence contexts. DNA methylation has been suggested to be critical for seed development, and CHH methylat...

Open AccessIdentification of small RNAs during cold acclimation in Arabidopsis thaliana
Cold stress causes dynamic changes in gene expression that are partially caused by small non-coding RNAs since they regulate protein coding transcripts and act in epigenetic gene silencing pathways. Thus, a de...

Open AccessSalt stress-induced FERROCHELATASE 1 improves resistance to salt stress by limiting sodium accumulation in Arabidopsis thaliana
Ferrochelatase-1 as a terminal enzyme of heme biosynthesis regulates many essential metabolic and physiological processes. Whether FC1 is involved in plant response to salt stress has not been described. This ...

Open AccessDefects in leaf carbohydrate metabolism compromise acclimation to high light and lead to a high chlorophyll fluorescence phenotype in Arabidopsis thaliana
We have studied the impact of carbohydrate-starvation on the acclimation response to high light using Arabidopsis thaliana double mutants strongly impaired in the day- and night path of photoassimilate export fro...

Use of Transcriptomics to Analyze Chloroplast Processes in Arabidopsis
The vast majority of the several thousands of chloroplast proteins are encoded by nuclear genes. Regulation of their expression involves control of their transcription, and thus requires the transmission of in...

Plastid-to-Nucleus Signaling
The function of the eukaryotic cell depends on the regulated and reciprocal interaction between its different compartments. This includes not only the exchange of energy equivalents but also information. Most ...
