Photosystem I (PSI) and PSII are two large pigment–protein complexes that are responsible for converting solar energy into chemical energy. We identify the PSI assembly factor PBF8 and show that it mediates two key consecutive steps in PSI assembly, revealing major aspects of the PSI assembly pathway in land plants.
