PNH — Brachypodium distachyon

Summary

BdPNH (BRADI_3G51077V3) encodes a protein containing Argonaute, Piwi, and PAZ domains, and is associated with a wide range of molecular functions including siRNA and miRNA binding, DNA-binding transcription activator activity, and histone ubiquitin ligase activity. The gene is linked to numerous biological processes such as miRNA and tasiRNA processing, gene silencing, regulation of cell fate specification, and somatic stem cell population maintenance. It has been connected to traits including leaf and inflorescence morphology, flower development, lignin biosynthesis, photosynthetic ability, gibberellic acid and cytokinin content, and responses to UV light and osmotic stress. Studies of related genes in other species link the family to shoot apical meristem development, leaf polarity, antiviral immunity, meiosis, drought stress response, and grain yield.
