PNH — Oryza sativa Japonica

Summary

OsPNH (also known as OsAGO1a, OsAGO7, and OsZIP) on rice chromosome 2 encodes a member of the Argonaute protein family, characterized by Piwi, PAZ, and Argonaute domains, and is associated with siRNA and miRNA binding. The gene is linked to a wide range of developmental and physiological processes, including appendage development, somatic stem cell population maintenance, miRNA metabolism, and temporal regulation of development. In rice, it has been connected to erect growth and antiviral immunity. Associations with numerous traits have been observed, including leaf morphology, leaf polarity, tiller angle, spikelet number, amylose content, photosynthetic ability, and gibberellic acid content. Studies of related genes in other species link the family to drought stress response, floral development, and shoot meristem organization.
