Research Abstract |
Higher plants have a number of PsbP homologs (PsbP-like proteins : PPLs, PsbP-domain proteins : PPDs) in addition to the authentic PsbP, which regulates the oxygen-evolving reaction in photosystem II (PSII). Among the PsbP homologs, PPL1 is co-expressed with PPD3 and required for the repair of photo-damaged PSII. Further analyses suggest that PPD3 is dispensable for high-light stress tolerance, while PPL1 has an important role in response to high-light stress in plants.
