Dynamic plastid redox signals integrate gene expression and metabolism to induce distinct metabolic states in photosynthetic acclimation in Arabidopsis.
Plants possess acclimation responses in which structural reconfigurations adapt the photosynthetic apparatus to fluctuating illumination. Long-term acclimation involves changes in plastid and nuclear gene expression and is controlled by redox signals from photosynthesis. The kinetics of these signals and the adjustments of energetic and metabolic demands to the changes in the photosynthetic app...
متن کاملWhy are plastid genomes retained in non-photosynthetic organisms?
The evolution of the plastid from a photosynthetic bacterial endosymbiont involved a dramatic reduction in the complexity of the plastid genome, with many genes either discarded or transferred to the nucleus of the eukaryotic host. However, this evolutionary process has not gone to completion and a subset of genes remains in all plastids examined to date. The various hypotheses put forward to e...
متن کاملComparative analysis of plastid genomes of non-photosynthetic Ericaceae and their photosynthetic relatives
Although plastid genomes of flowering plants are typically highly conserved regarding their size, gene content and order, there are some exceptions. Ericaceae, a large and diverse family of flowering plants, warrants special attention within the context of plastid genome evolution because it includes both non-photosynthetic and photosynthetic species with rearranged plastomes and putative losse...
متن کاملEvolution and Functional Diversification of Fructose Bisphosphate Aldolase Genes in Photosynthetic Marine Diatoms
Diatoms and other chlorophyll-c containing, or chromalveolate, algae are among the most productive and diverse phytoplankton in the ocean. Evolutionarily, chlorophyll-c algae are linked through common, although not necessarily monophyletic, acquisition of plastid endosymbionts of red as well as most likely green algal origin. There is also strong evidence for a relatively high level of lineage-...
متن کاملThe fructose-1,6-bisphosphate aldolases: same reaction, different enzymes.
Two forms of the enzyme fructoseI ,6-bisphosphate aldolase (EC 4. I .2.13) are known, designated class I and class 11. The enzymes o f class I function by imine formation between the substrate and a catalytically essential lysine residue in the active site, which acts to stabilize the intermediate carbanion (for review, see [ I , 21). The enzymes of class I1 utilize a divalent metal ion to act ...
