PNH — Oryza sativa Indica Group

Summary

BGIOSGA023644 (PNH, OiPNH) on chromosome 6 of Indica rice encodes a protein with Piwi and Argonaute domains, and is annotated with multiple molecular functions including siRNA binding, miRNA binding, and histone ubiquitin ligase activity. In rice, PNH is associated with sheath and erect growth, reproductive development, meiosis, cell division, seed and grain traits, plant height, tillering, yield, and antiviral immunity. It is linked to processes including miRNA metabolism, siRNA processing, gene silencing, auxin transport, and stem cell maintenance. The gene is also associated with leaf polarity and morphology, shoot apical meristem initiation, auxin signaling, and virus resistance. Related genes in other species are linked to drought stress response, floral development, shoot meristem organization, and heat tolerance.
