Intracellular signalling: The chloroplast talks!
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.
متن کاملIntracellular Signalling: Chloroplast Backchat
Chloroplast-derived signals modulate expression of nuclear genes for chloroplast proteins. GUN1 has recently been identified as a chloroplast-localized pentatricopeptide repeat protein that integrates information from several different signalling pathways.
متن کاملIntracellular Signalling: The Language of the Chloroplast
Chloroplasts emit signals that modulate nuclear gene expression, thereby ensuring the proper assembly of the photosynthetic apparatus. Recent studies have provided major new insights into one of these signalling mechanisms, and identified the chlorophyll precursor Mg-protoporphyrin IX as a key signalling molecule.
متن کاملBlue light signalling in chloroplast movements.
Chloroplast movements are among the mechanisms allowing plants to cope with changes in their environment. Chloroplasts accumulate at illuminated cell areas under weak light while they avoid areas exposed to strong light. These directional responses may be controlled by blue and/or red light, depending on the plant group. In terrestrial angiosperms only the blue light perceived by phototropins i...
متن کاملIntracellular Signalling by C-Peptide
C-peptide, a cleavage product of the proinsulin molecule, has long been regarded as biologically inert, serving merely as a surrogate marker for insulin release. Recent findings demonstrate both a physiological and protective role of C-peptide when administered to individuals with type I diabetes. Data indicate that C-peptide appears to bind in nanomolar concentrations to a cell surface recepto...
