The external light-collecting antennas (PSI and PSII) of the photosystem of the green single-celled algae Chlamydomonas reinhardtii consist of a family of pigment-binding proteins (Lhc), which are highly conserved in photosynthetic eukaryotes. Some of the lhc subtypes of Chlamomonas have a high enough similarity to their respective functional homologues in plants to enable specific detection of the conserved peptide domain of plant lhc proteins with antisera.
