PNH — Oryza sativa Japonica

Summary

OsPNH (OS03G0789466) on rice chromosome 3 encodes an Argonaute family protein with PAZ, Piwi, and Mid domains, possessing RNA endonuclease activity and RNA binding. It is associated with appendage development, xylem development, trichome morphogenesis, stem cell population maintenance, male and female meiotic nuclear division, microgametogenesis, megagametogenesis, cell development, zinc import, gibberellin and glycan biosynthesis, sucrose metabolism, and cellulose anabolism. The gene is linked to grain yield, grain size, plant height, tiller number and angle, spikelet number, leaf shape and size, root length, water use efficiency, photosynthetic rate, stomatal resistance, and tolerance to heat, drought, and salt. The protein localises to the nucleus, cytoplasm, nucleolus, and nucleolar organising region.
