PNH — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.7HG0714440, designated HvPNH, encodes an Argonaute-family protein with RNA endonuclease activity and RNA binding capacity, localising to the nucleus, nucleolus, NOR and cytoplasm. HvPNH is associated with stem cell population maintenance, micro- and megagametogenesis, female and male meiotic nuclear division, upregulation of meiotic DNA double-strand break formation, leaf development, response to water and jasmonic acid, detoxification, homeostasis, and RNA-dependent gene silencing. The gene has been connected to grain number, spikelet fertility, drought tolerance, water use efficiency, quantum yield, sugar content, and zinc concentration. Studies of related genes in other species link the family to spikelet number.
