PNH — Zea mays

Summary

ZM00001EB258420, designated PNH (ZmPNH), encodes a Piwi domain-containing protein with RNA endonuclease activity and nucleic acid binding. Located in the nucleus, nucleolus, and cytoplasm, this maize gene on chromosome 5 is associated with diverse biological processes including meristem determinacy, leaf formation, trichome differentiation, female meiotic nuclear division, microgametogenesis, and floral organ abscission. PNH has been linked to multiple agronomically important traits such as grain yield, grain weight, grain length, seed size, ear weight, rolled leaf, chlorophyll content, anthesis time, drought tolerance, and acid sensitivity. Additional associations include responses to hormones and nutrients, lignin and proline content, and regulation of cellular localization. Related genes in other species include Argonaute family members.
