Plant cells have a unique problem: the coordination of three different genomes. While the dominance of the nuclear genome is indisputable, it is now clear that organellar signals can have profound effects, not just on nuclear gene expression but, as the Arabidopsis laf6 mutant reveals, also on whole plant morphology.

TLDR
The chlorophyll precursor Mg-protoporphyrin IX is identified as a key signalling molecule that modulates nuclear gene expression in chloroplasts, thereby ensuring the proper assembly of the photosynthetic apparatus. Expand
Covariations in the nuclear chloroplast transcriptome reveal a regulatory master‐switch
TLDR
It is shown by the differential‐expression analysis of 3,292 genes, that most of the 35 environmental and genetic conditions tested, including plastid signalling mutations, elicit only three main classes of response from the nuclear chloroplast transcriptome. Expand
Nifs and Sufs in malaria
TLDR
A bacterial operon, recently found to be involved in iron metabolism, the formation of [Fe–S] clusters and oxidative stress to a potentially important gene (sufB) carried on the degenerate plastid genome of malaria and related parasites is connected. Expand
Pathways of plastid-to-nucleus signaling.

  • 2001
TLDR
Retrograde signaling plays a central role in coordinating gene expression in the nucleus, plastid and mitochondrion, and in integrating pathways of cellular metabolism and development. Expand
Chloroplast to nucleus communication triggered by accumulation of Mg-protoporphyrinIX
TLDR
It is shown that the tetrapyrrole intermediate Mg-protoporphyrin (Mg-ProtoIX) acts as a signalling molecule in one of the signalling pathways between the chloroplast and nucleus. Expand
Does complexity constrain organelle evolution?
  • W. Zerges
  • Biology, Medicine
  • Trends in plant science
  • 2002
TLDR
Here, this work reviews complex processes that directly involve translation of plastid mRNAs and how they could constrain transfer to the nucleus of the genes encoding them. Expand
Plastidial retrograde signalling--a true "plastid factor" or just metabolite signatures?
TLDR
The current models of retrograde signalling are critically assessed and novel ideas and potential connections are discussed, potentially obstructing the view on alternative routes for retrograde communication. Expand
Plastid-nucleus communication: anterograde and retrograde signalling inthe development and function of plastids
TLDR
The interaction and mutual dependency of anterograde and retrograde signals are discussed and models are presented that provide a unifying view of the different known pathways between the plastid and nucleus. Expand
Progress with parasite plastids.

TLDR
This review offers a snapshot of the current understanding of the origin, biology, and metabolic significance of the non-photosynthetic plastid organelle found in apicomplexan parasites and exposes many gaps remaining in knowledge of this intriguing organelle. Expand
Plastid protein synthesis is required for plant development in tobacco
TLDR
An essential role of plastid protein synthesis in tobacco leaf development is demonstrated by using chloroplast transformation to develop an experimental system that produces recombination-based knockouts ofchloroplast translation in a cell-line-specific manner and points to an unexpected essential role in plant development and cell division.

Plastids are ubiquitous plant cell organelles that perform many essential functions. Chloroplasts are the most complex type of plastid, both structurally and functionally, containing six distinctExpand
Posttranscriptional control of chloroplast gene expression. From RNA to photosynthetic complex.
Twenty-five years ago it was well established that chloroplasts contain their own DNA and protein synthesizing system, but little was known of how this organellar genome is expressed. As a result ofExpand

The origin of oxygenic photosynthesis must rank just after the origin of life itself as one of the most significant events in the history of life. The early photosynthesizers, which Bill Schopf hasExpand
Inter-organellar crosstalk in higher plants: impaired chloroplast development affects mitochondrial gene and transcript levels.
TLDR
The results indicate an influence of plastids on the genetic apparatus of mitochondria in leaves but not in roots, and allow the conclusion that lack of chloroplast activity in an otherwise fully differentiated leaf leads to an increase in mitochondrial gene copy number and an elevated level of mitochondrial transcripts. Expand
A plastidic ABC protein involved in intercompartmental communication of light signaling.
TLDR
Observations suggest that functional atABC1 is required for the transport and correct distribution of protoporphyrin IX, which may act as a light-specific signaling factor involved in coordinating intercompartmental communication between plastids and the nucleus. Expand
Signal transduction mutants of arabidopsis uncouple nuclear CAB and RBCS gene expression from chloroplast development
TLDR
This work has identified at least three Arabidopsis nuclear genes (GUN1, GUN2, and GUN3) necessary for coupling the expression of some nuclear genes to the functional state of the chloroplast and defines steps in one specific branch of a complex interorganellar regulatory network. Expand
Interactions between hy1 and gun mutants of Arabidopsis, and their implications for plastid/nuclear signalling.
TLDR
Results can be interpreted as a metabolic (rather than genetic) interaction between HY1 and GUN4 or GUN5, and this in turn supports the involvement of tetrapyrroles as plastid signals. Expand
Plastid redox state and sugars: interactive regulators of nuclear-encoded photosynthetic gene expression.
TLDR
It is shown that a block in photosynthetic electron flux prevents the increase in transcript levels of chlorophyll a/b-binding protein and the small subunit of Rubisco that typically occurs when intracellular sugar levels are depleted, and concludes that plastid-derived redox signaling can override the sugar-regulated expression of nuclear-encoded photosynthesis genes. Expand
New Arabidopsis cue mutants suggest a close connection between plastid- and phytochrome regulation of nuclear gene expression.
TLDR
It is proposed that the previously postulated plastid-derived signal is closely involved in the pathway through which phytochrome regulates the expression of nuclear genes encodingplastid proteins. Expand
Chlorophyll precursors are signals of chloroplast origin involved in light induction of nuclear heat-shock genes.
TLDR
Using Chlamydomonas, evidence is provided that plastid-derived chlorophyll precursors may replace light in the induction of two nuclear heat-shock genes (HSP70A and HSP70B) and thus qualify as plastsidic signal. Expand
