PNH — Zea mays

Summary

ZM00001EB356140 (ZmPNH) encodes an Argonaute1 protein with RNA endonuclease activity and RNA binding. The gene is associated with a wide range of developmental and physiological processes, including leaf formation, meristem determinacy, trichome differentiation, female meiotic nuclear division, microgametogenesis, floral organ abscission, and dehiscence. It has been linked to agronomically important traits such as grain yield, grain weight, grain length, grain size, seed size, ear weight, rolled leaf, inflorescence branching, anthesis time, chlorophyll content, lignin content, proline content, drought tolerance, and sensitivity to abscisic acid and acid. The protein localises to the nucleus, cytoplasm, and nucleolus. Studies of related Argonaute proteins in other species further connect the family to small RNA-mediated regulation.
