Post-endosymbiotic evolution of chloroplasts was characterized by a massive transfer of cyanobacterial genes to the nucleus, followed by re-routing of many of their encoded proteins. In consequence, most plastid proteins are nucleus-encoded, enabling an anterograde (nucleusto-plastid) control of the organelle. The regulation of chloroplast functions includes also cross-talk between chloroplasts and mitochondria, as well as retrograde (plastid-to-nucleus) signalling. Genetic analyses reveal that redox state, flux through the chlorophyll biosynthetic pathway, sugar sensing and reactive oxygen species contribute to retrograde signalling. However, the identity of the messenger molecule(s) remains largely unknown. Novel facets of the chloroplast -mitochondrion cross-talk have been revealed by the characterization of mitochondrial mutants affected in chloroplast properties. Studies of the nuclear chloroplast transcriptome imply the existence of at least three distinct types of transcriptional regulation: a master switch, acting in a binary mode by either inducing or repressing the same large set of genes; a ''mixed response'' with about equal numbers of up-and down-regulated genes; and mechanisms supporting the specific co-regulation of nuclear genes for photosynthesis and for plastid gene expression. The recent discovery of the latter mode of control highlights a possibly ancient route to co-ordinate chloroplast and nuclear genome expression. D

“…It is widely accepted that there is nuclear control of many aspects of chloroplast biogenesis (Leon et al, 1998). Several mutants in nuclear genes have impaired chloroplast transcription and translation (Gutierrez-Nava et al, 2004;Mandel et al, 1996;Pfalz et al, 2006), protein assembly and import into the organelle (Constan et al, 2004;Kubis et al, 2004;Sundberg et al, 1997), chloroplast division (Aldridge et al, 2005;Pyke, 1999), response to external stimulus such as the light (Chun et al, 2001) and communication between the chloroplast and nucleus (Larkin et al, 2003;Mochizuki et al, 2001).…”

Analysis of chlorophyll fluorescence reveals stage specific patterns of chloroplast-containing cells during Arabidopsis embryogenesis

The basic body plan of a plant is established early in embryogenesis when cells differentiate, giving rise to the apical and basal regions of the embryo. Using chlorophyll fluorescence as a marker for chloroplasts, we have detected specific patterns of chloroplast-containing cells at specific stages of embryogenesis. Nonrandomly distributed chloroplast-containing cells are seen as early as the globular stage of embryogenesis in Arabidopsis. In the heart stage of embryogenesis, chloroplast containing cells are detected in epidermal cells as well as a central region of the heart stage embryo, forming a triangular septum of chloroplast-containing cells that divides the embryo into three equal sectors. Torpedo stage embryos have chloroplast-containing epidermal cells and a central band of chloroplast-containing cells in the cortex layer, just below the shoot apical meristem. In the walking-stick stage of embryogenesis, chloroplasts are present in the epidermal, cortex and endodermal cells. The chloroplasts appear reduced or absent from the provascular and columella cells of walking-stick stage embryos. These results suggest that there is a tight regulation of plastid differentiation during embryogenesis that generates specific patterns of chloroplast-containing cells in specific cell layers at specific stages of embryogenesis.

“…As a result, the number of chloroplasts increases dramatically during mesophyll cell expansion producing large population of chloroplasts in each mature mesophyll cells (Pyke and Leech, 1992) or simply, chloroplasts develop from proplastids through a process that involves an increase in volume and membrane expansion (Reiter et al, 1994). Although chloroplast differentiation appears to start very early during plant development (Leon et al, 1998), the stages of chloroplast differentiation at various ages of plants or leaf tissues in a variety of species are not yet well established. It can also be asserted that the chloroplast development could be dependent on plant species, environmental factors and different growing conditions.…”

The development of chloroplasts in the mesophyll cells of control and urea-applied satsuma mandarin leaves were studied. At 20 days after budding (DAB) active differentiation of chloroplasts in urea-applied trees was evident. However, on a length times width basis, chloroplasts were small in both palisade (1.99 × 0.70 µm ) starch grains. The thylakoid layers per chloroplast were lesser (2.80) in this treatment compared to control (3.72). At 40 DAB, both control and urea-applied trees reached chloroplast maturity, but control trees had bigger chloroplast (4.87 × 2.39 µm 2 ) in the palisade layer cells which contained extremely large and numerous starch grains with few dilated thylakoid layers. Degenerating chloroplasts in the spongy layer cells of control trees were characterized by the disappearance of the outer membrane. While urea-applied trees had smaller chloroplast (4.56 × 2.39 µm 2 ) in the palisade layer. Further, few small starch grains, thylakoid-filled stroma and many lipid droplets were found. Moreover, thylakoid layers were about to dilate but outer membrane of the chloroplasts remained intact in both palisade and spongy layer cells. Compared to the palisade layer cells, chloroplasts in the spongy were bigger (5.32 x 1.95 µm 2 ).
