    Summary
    Encodes for the 10 kDa PsbR subunit of photosystem II (PSII). This subunit appears to be involved in the stable assembly of PSII, particularly that of the oxygen-evolving complex subunit PsbP. Mutants defective in this gene have reduced amounts of subunits PsbP and PsbQ in PSII. In turn, assembly of PsbR is dependent on the presence of PsbJ.

    GeneRIFs: Gene References Into Functions

    What's a GeneRIF?
    1. Complete elimination of PsbQ has a minor effect on photosystem II (PSII) function, but plants lacking PsbR or both PsbR and PsbQ are characterized by more pronounced defects in PSII activity.
      Title: Arabidopsis plants lacking PsbQ and PsbR subunits of the oxygen-evolving complex show altered PSII super-complex organization and short-term adaptive mechanisms.
    2. the functional defects observed in the mutant were due to defective assembly and/or binding of the PsbP and PsbQ components to Photosystem II in the absence of the PsbR protein.
      Title: Characterization and complementation of a psbR mutant in Arabidopsis thaliana.
    3. PsbR is an important link in the PSII core complex for stable assembly of the oxygen-evolving complex protein PsbP, whereas the effects on the assembly of PsbQ are probably indirect
