The nature of the phycobilisome–photosystem II supercomplex on the native thylakoid determined with cryo-electron tomography at an unprecedented resolution reveals that one phycobilisome interconnects with six photosystem monomers.
Horizontal gene transfer (HGT) analysis in polyextremophile red algae (Cyanidiales) provides explanations for the nonexistence of cumulative effects and eukaryotic pangenomes, and highlights differences between HGT and native genes.
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.
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.
The symbiotic relationship between Hydra and Chlorella is driven by metabolic co-dependence and characterized by changes in the photobiont genome in terms of lack of genes essential in free-living algae.
