PNH — Oryza sativa Japonica

Summary

Os06g0729300, also known as PNH, ZIP, OsAGO1d, or OsAGO7, encodes an Argonaute family protein with RNA endonuclease activity and nucleic acid binding, containing Piwi, PAZ, and RNaseH-like domains. In rice, this gene is associated with male fertility, anther and tapetal development, and temperature-sensitive male sterility, as well as programmed cell death. It has been linked to a wide range of agronomic traits including grain yield, grain size, tiller number and angle, plant height, spikelet number, leaf shape and size, rolled leaf, amylose content, root length, and stress tolerance such as drought, cold, heat, and salt tolerance. The protein localizes to the nucleus, cytoplasm, and nucleolus, and is associated with processes including microgametogenesis, megagametogenesis, stem cell maintenance, xylem development, and gibberellin biosynthesis.
