PNH — Oryza sativa Indica Group

Summary

BGIOSGA005861 (PNH, OiPNH) on Indica rice chromosome 2 encodes a protein with Argonaute and Piwi domains, and is annotated with multiple molecular functions including siRNA binding, miRNA binding, dsRNA binding, and histone ubiquitin ligase activity. In rice, PNH is associated with sheath and erect phenotypes, reproductive growth, meiosis, cell division, seed and grain traits, plant height, tillering, yield, and antiviral immunity. It is linked to biological processes including miRNA and siRNA processing, gene silencing by miRNA, somatic stem cell maintenance, and regulation of body size. Additional associations include leaf polarity, leaf morphology, shoot apical meristem initiation, auxin signaling, virus resistance, and responses to UV light, cadmium, and osmotic stress. Studies of related genes in other species connect the family to drought stress response, floral development, shoot meristem organization, and heat tolerance.
