AGO5 — Phaseolus vulgaris

Summary

PHAVU_011G088200, designated PvAGO5, encodes an Argonaute family protein with RNA endonuclease activity and RNA binding capacity, containing Piwi, PAZ, and RNaseH-like domains. In French bean, this gene is associated with RNA-dependent gene silencing, virus-induced post-transcriptional gene silencing, and defense responses to viruses and other organisms. It is linked to female and male meiotic nuclear division, microgametogenesis, megagametogenesis, pigmentation, nodulation, leaf development, stem cell population maintenance, and responses to jasmonic acid. The protein localizes to the nucleus, nucleolus, NOR, cytosol, and cytoplasm. Associations with germination time, viroid resistance, and antiviral defense have also been noted. Studies of related genes in other species link the AGO5 family to flowering time and sexual reproduction.
