PNH — Oryza sativa Japonica

Summary

OS07G0471300, also known as AGO18, PNH, or ZIP in rice (Oryza sativa Japonica) on chromosome 7, encodes an Argonaute family protein with Piwi, PAZ, and RNaseH-like domains and exhibits RNA endonuclease activity and RNA binding. The gene is associated with development, fertility, male fertility, and resistance phenotypes in rice. It has been linked to a wide range of biological processes including appendage development, zinc import, upregulation of meiotic DNA double-strand break formation, female and male meiotic nuclear division, cellular response to virus, microgametogenesis, megagametogenesis, xylem development, stem cell population maintenance, trichome morphogenesis, and glycan, gibberellin, and cellulose biosynthesis. Associations with agronomically important traits include tiller angle, rolled leaf, amylose content, spikelet number, grain size, grain yield, plant height, tiller number, leaf shape and size, root length, water use efficiency, heat tolerance, photosynthetic rate, stomatal resistance, drought tolerance, and salt tolerance. The protein localises to the nucleus, cytoplasm, and nucleolus.
