Abstract:
Signals originating from chloroplasts and mitochondria
modulate nuclear gene expression (retrograde signalling).
Relevant signals are derived from the pool of reactive oxygen
species or generated by changes in redox state, flux through
the tetrapyrrole biosynthetic pathway, or rates of organelle
protein synthesis. In addition, multiple interactions of these four
pathways with sugar and hormone signalling occur. Although
the nature of the molecules that relay information through the
cytosol to the nucleus is still unknown, the first putative
signalling components in the chloroplast have recently been
identified, and give tentative hints of overlaps between the
different pathways. Retrograde signalling-dependent
modulation of nuclear gene expression seems to involve
multilayered transcriptional control and the transcription factor
ABI4.
