PNH — Zea mays

Summary

ZmPNH (ZM00001EB239980) on maize chromosome 5 encodes a Piwi domain-containing protein with RNA endonuclease activity and nucleic acid binding. It is associated with regulation of cellular localization, oviposition, leaf abscission, trichome spacing, female meiotic nuclear division, dehiscence, meristem determinacy, microgametogenesis, and response to virus, hormone, and nutrient. The gene has been linked to grain yield, grain weight, grain length, grain size, seed size, ear weight, rolled leaf, inflorescence branching, chlorophyll content, lignin content, proline content, abscisic acid sensitivity, acid sensitivity, drought tolerance, anthesis time, and salt tolerance. The protein localizes to the nucleus, nucleolus, cytoplasm, and NOR.
