PNH — Oryza sativa Indica Group

Summary

BGIOSGA025669 (PNH, OiPNH) on indica rice chromosome 7 encodes a protein argonaute 18, a member of the Piwi/Argonaute family with RNA endonuclease activity and RNA binding. It is associated with RNA-dependent gene silencing, regulation of gene expression, and antiviral and cellular responses to virus. The gene is linked to upregulation of meiotic DNA double-strand break formation, male and female meiotic nuclear division, microgametogenesis, megagametogenesis, gametophyte development, and pollen development. It is associated with stem cell population maintenance, leaf development, response to jasmonic acid, metabolic burst, detoxification, NO storage, and homeostasis. The product localises to the nucleus, nucleolus, NOR, and cytoplasm. Panicle length is also associated with this gene. Studies of related genes in other species further link the family to small RNA-mediated gene regulation and reproductive development.
