PNH — Zea mays

Summary

ZmPNH (ZM00001EB267430) on maize chromosome 6 encodes an Argonaute1a protein with RNA endonuclease activity and RNA binding, containing Piwi, PAZ, and RNaseH-like domains. This gene is associated with numerous biological processes including meiotic S phase, female meiotic nuclear division, microgametogenesis, meristem determinacy, leaf formation, leaf abscission, floral organ abscission, dehiscence, trichome spacing, regulation of cellular localization, response to hormone, protein processing, demethylation, secondary metabolite biosynthesis, and regulation of response to thirst. It localizes to the nucleus, nucleolus, NOR, and cytoplasm. The gene has been connected to agronomically important traits including grain yield, grain weight, grain length, grain size, seed size, ear weight, rolled leaf, chlorophyll content, lignin content, proline content, anthesis time, drought tolerance, acid sensitivity, abscisic acid sensitivity, and inflorescence branching.
