    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. Results indicate that the loss of the PsbQ protein induces significant changes in Photosystem II function, particularly in low light-grown plants, and that the PsbQ protein is required for photoautotrophic growth under low light conditions.
      Title: The PsbQ protein is required in Arabidopsis for photosystem II assembly/stability and photoautotrophy under low light conditions.
