NPP5 — Daucus carota subsp. sativus

Summary

DCAR_015715 (symbol NPP5, also known as PP2A-4, PP2A-3, or DcPP2A) on carrot chromosome 4 encodes a protein phosphatase belonging to the PPA2-like family with serine/threonine phosphatase activity, protein phosphatase regulator activity, and kinase binding capability. The gene is associated with TOR signaling, stem cell differentiation, protein dephosphorylation, negative regulation of leaf senescence, regulation of nitrogen utilization, primary root development, downregulation of seed germination, mitotic cell cycle, root development, response to cold, and response to abscisic acid. It localizes to the PP2A complex, nucleolus, cytosol, cytoplasm, and nucleus. Associations include root mass density, seed maturation, leaf senescence, plant growth and development traits, as well as phenotypes such as short primary root with disrupted root tip organization, longer primary root with reduced columella stem cell differentiation, and altered seed size, germination, and ABA sensitivity.
