PNH — Zea mays

Summary

ZM00001EB421780, designated PNH (ZmPNH), encodes a Piwi domain-containing protein with RNA endonuclease activity and nucleic acid binding capacity. This maize gene on chromosome 10 is associated with a wide range of developmental and agronomic traits, including grain yield, grain weight, grain length, seed size, ear weight, and inflorescence branching. It has been linked to leaf formation, leaf abscission, floral organ abscission, meristem determinacy, trichome spacing and differentiation, female meiotic nuclear division, microgametogenesis, and dehiscence. Additional associations include responses to hormones, nutrients, drought tolerance, acid sensitivity, abscisic acid sensitivity, anthesis time, and levels of chlorophyll, lignin, and proline. The protein localises to the nucleus, nucleolus, cytoplasm, and nucleolar organising region.
