    What's a GeneRIF?
    1. Regulation of sucrose-phosphate synthase by BSK8 occurs through activation of a phosphatase that in turn may dephosphorylate sucrose-phosphate synthase and thus activates the enzyme.

    2. SPSA1 plays a role in photosynthetic sucrose synthesis in Arabidopsis leaves. Decreases in leaf SPS activity lead to increased starch synthesis and turnover, and decreased RuBP regeneration-limited photosynthesis but not Rubisco-limited photosynthesis.
