PNH — Brachypodium distachyon

Summary

BdPNH (BRADI_3G60697V3) on chromosome 3 of Brachypodium distachyon encodes a protein containing Piwi, PAZ, and Argonaute domains, characteristic of the Argonaute family. It is annotated with diverse molecular functions including siRNA and miRNA binding, DNA-binding transcription activator activity, and histone ubiquitin ligase activity. The gene is associated with numerous biological processes such as miRNA and siRNA processing, gene silencing by miRNA, regulation of cell fate specification, somatic stem cell population maintenance, and temporal regulation of development. It is linked to traits including leaf shattering, inflorescence development, photosynthetic ability, lignin biosynthesis, root phototropism, and responses to UV light and osmotic stress. Related genes in other species are associated with shoot apical meristem function, leaf morphology, meiosis, antiviral immunity, drought stress response, and grain yield.
