PNH — Zea mays

Summary

ZmPNH (ZM00001EB386880) on maize chromosome 9 encodes a PAZ domain-containing protein with RNA endonuclease activity and RNA binding. It is associated with regulation of cellular localization, oviposition, leaf abscission, trichome spacing, female meiotic nuclear division, cellular response to virus, dehiscence, protein processing, leaf formation, meristem determinacy, microgametogenesis, and demethylation. The gene has been connected to agronomically important traits including ear weight, grain length, grain size, grain weight, grain yield, seed size, rolled leaf, inflorescence branching, anthesis time, drought tolerance, chlorophyll content, lignin content, proline content, and abscisic acid sensitivity. It localizes to the nucleolus, cytoplasm, and nucleus. Related genes in other species link the family to small RNA-mediated gene regulation.
