Environmentally-informed functional characterisation of the secondary red chloroplast proteome

Photosynthesis in the ocean is as significant as that of land plants, and is performed by a wide range of cyanobacteria and eukaryotic algae, the most abundant of which have originated through the secondary endosymbioses of red algae. Previously, I have shown that these ""secondary red chloroplasts"" are evolutionary mosaics, supported by nucleus-encoded proteins of symbiont, host and horizontally acquired origin
