PNH — Brachypodium distachyon

Summary

BRADI_1G05162V3 (BdPNH) encodes a member of the Argonaute protein family, containing Piwi, PAZ, and RNaseH-like domains, and is associated with a wide range of molecular functions including siRNA and miRNA binding, histone ubiquitin ligase activity, and DNA-binding transcription activator activity. In Brachypodium distachyon, this gene is linked to miRNA metabolic processes, long siRNA processing, gene silencing by miRNA-directed mRNA cleavage, and the regulation of cell fate specification and body size. It has also been connected to traits such as leaf shattering, inflorescence development, photosynthetic ability, lignin biosynthesis, root phototropism, and responses to UV light and osmotic stress. Studies of related genes in other species link the family to shoot apical meristem initiation, leaf polarity, antiviral immunity, drought stress response, grain yield, and reproductive development.
