RP1 — Zea mays

Summary

ZM00001EB106240 (symbol RP1, also known as ZmRP1, ZmPDRP1, or RP2) on maize chromosome 2 encodes a protein with the PPDK regulatory domain and is annotated with phosphotransferase activity, protein phosphatase activity, and protein serine/threonine kinase activity. The gene is associated with C4 photosynthesis, phloem loading, electron transport chain, sucrose metabolism, and calcium signaling, and its product localizes to the chloroplast stroma and cytosol. It has been linked to gene conversion, meiosis, metaphase, interphase, de-etiolation, autophagy, vacuolar protein sorting, digestion, regeneration, and virus-induced PTGS. Agronomically, RP1 is associated with stem rust, biomass yield, water use efficiency, and drought tolerance. Studies of related genes in other species connect the family to iron concentration, photochemical quenching, and root morphology traits.
