Serial-Block-Face Scanning Electron Microscopy (SBF-SEM) associated with biomolecular analysis show that chloroplast differentiation proceeds by distinct ‘structure establishment’ and ‘chloroplast proliferation’ phases, each with differential protein and lipid regulation.
The newly opened genome of a kleptoplastic mollusk, Plakobranchus ocellatus, indicated that sequestered plastids retain their activity within the animal cell without horizontal algal gene transfer to the animal nucleus.
An iron-sensitive gene cluster encodes proteins that co-localize with phytotransferrin endosomes and are involved in key intracellular iron transformation and trafficking processes in a model marine diatom.
An in silico reconstruction of a chloroplast that existed hundreds of millions of years ago casts new insights in the evolutionary processes, endosymbioses and chimerism events that shape the origin of plastids.
A combination of chloroplast transformation with nuclear transformation and large-scale metabolic screening of supertransformed plant lines has enabled an entire biochemical pathway to be transferred from a medicinal plant to a high-biomass crop.
Carotenoids are not just required as core components for plastid biogenesis, they can be cleaved into an apocarotenoid signal that regulates etioplast and chloroplast development during extended periods of darkness.
Genomic evidence suggests that L-gulonolactone oxidase-the terminal enzyme in vitamin C synthesis, which has been repeatedly lost throughout animal evolution-was lost in plants and other photosynthetic eukaryotes following plastid acquisition.
