Taxonomic distribution and origins of the extended LHC (light-harvesting complex) antenna protein superfamily

Background: The extended light-harvesting complex (LHC) protein superfamily is a centerpiece of eukaryotic photosynthesis, comprising the LHC family and several families involved in photoprotection, like the LHC-like and the photosystem II subunit S (PSBS). The evolution of this complex superfamily...
