PNH — Oryza sativa Japonica

Summary

OsPNH (OS03G0682200) on rice chromosome 3 encodes a protein containing Piwi and Argonaute Mid domains, with annotated molecular functions including siRNA binding, miRNA binding, and dsRNA binding. The gene is associated with miRNA and long siRNA processing, gene silencing by miRNA-directed mRNA cleavage, and the regulation of rRNA processing. In rice, OsPNH has been linked to erect growth and antiviral immunity. It is also connected to a wide range of traits including leaf shattering, tiller angle, rolled leaf, amylose content, photosynthetic ability, spikelet number, and responses to UV-A and UV-B light. Additional associations include auxin signaling, leaf polarity and morphology, meristem development, and the juvenile-to-adult transition. Studies of related genes in other species link the family to developmental timing, floral organ development, and drought stress response.
