TranscriptomicsSigma2 and Sigma6-mediated plastid retrograde signals control nuclear gene expression in Arabidopsis
Retrograde signaling from the chloroplast to the nucleus is necessary to regulate the chloroplast proteome during development and fluctuating environmental conditions. Although the specific chloroplast process(es) that must occur and the nature of the signal(s) that exits the chloroplast are not wel...

ProteomicsThe Plastid Proteome of the Nonphotosynthetic Chlorophycean Alga Polytomella parva
The unicellular, free-living, nonphotosynthetic chlorophycean alga Polytomella parva, closely related to Chlamydomonas reinhardtii and Volvox carteri, contains colorless, starch-storing plastids. The P. parva plastids lack all light-dependent processes but maintain crucial metabolic pathways. The co...

ProteomicsFast light changes promote distinct responses of plastid protein acetylation marks
Protein acetylation is a key recurring co- and posttranslational modification. How different types of acetylation respond to the same environmental stress is unknown. A member of the newly discovered family of plastid acetyltransferases (GNAT2), which is featuring both lysine- and N-terminal acetyl...

TranscriptomicsThe primary transcriptome of barley (Hordeum vulgare L.) chloroplasts
Gene expression in plastids of higher plants is dependent on two different transcription machineries, a plastid-encoded bacterial-type RNA polymerase (PEP) and a nuclear-encoded phage-type RNA polymerase (NEP), which recognize distinct types of promoters. The division of labor between PEP and NEP du...

ProteomicsSubcellular proteomics for determining iron limited remodeling of plastids in the model diatom Thalassiosira pseudonana
Diatoms are important primary producers in the world’s oceans, yet their growth is constrained in large regions by low bioavailable iron (Fe). Low Fe-induced limitation of primary production is due to requirements for Fe in components of essential metabolic pathways including photosynthesis and othe...

ProteomicsThe Arabidopsis Protein CONSERVED ONLY IN THE GREEN LINEAGE20 is Required for Plastid 50S Ribosome Biogenesis
Biogenesis of plastid ribosomes is assisted by auxiliary factors which process and modify ribosomal RNAs (rRNA) or are involved in ribosome assembly. In comparison to bacterial and mitochondrial ribosomes, plastid ribosome biogenesis is less well understood and only few auxiliary factors have been d...

TranscriptomicsTranscription profiling of Arabidopsis wild type, flu, ex1/flu, ex2/flu, and ex1/ex2/flu (all Col0) grown under continuous light reveals EXECUTER1- and EXECUTER2-dependent transfer of stress signals from the plastid to the nucleus
Shortly after the release of singlet oxygen (1O2), drastic changes in nuclear gene expression occur in the conditional flu mutant of Arabidopsis that reveal a rapid transfer of signals from the plastid to the nucleus. In contrast to retrograde control of nuclear gene expression by plastid signal...
