PNH — Oryza sativa Indica Group

Summary

BGIOSGA005301 (PNH, also known as OiPNH) encodes a protein containing Piwi, PAZ, and Argonaute domains, and is annotated with diverse molecular functions including siRNA binding, miRNA binding, histone ubiquitin ligase activity, and superoxide dismutase activity. In indica rice, PNH is associated with numerous developmental and agronomic traits: it has been linked to sheath development, reproductive growth, meiosis, cell division, seed and grain traits, plant height, tillering, yield, and antiviral immunity. The gene is also associated with biological processes such as miRNA metabolism, siRNA processing, gene silencing by miRNA, female meiotic nuclear division, and regulation of cell fate specification. Additional associations include leaf polarity, auxin signaling, virus resistance, cadmium uptake, and UV light sensitivity. Studies of related genes in other species link the family to drought stress response, floral development, and shoot meristem organization.
