    What's a GeneRIF?
    1. These results suggest a close correlation between the function of PPSB and photorespiration, and also nitrogen metabolism in leaves.
      Title: Overexpression of PSP1 enhances growth of transgenic Arabidopsis plants under ambient air conditions.
    2. Data indicate that lack of phosphoserine phosphatase PSP1 (At1g18640) activity delayed embryo development, leading to aborted embryos that could be classified as early curled cotyledons.
