Abstract:
Signalling from chloroplasts to the nucleus is an important feature of the coordination of nuclear and chloroplast gene expression required for the assembly of functional chloroplasts. Recent studies have indicated that accumulation of Mg-protoporphyrin, the first committed precursor of chlorophyll, is both necessary and sufficient for the regulation of nuclear genes by chloroplasts.
