PNH — Brachypodium distachyon

Summary

BdPNH (BRADI_1G12431V3) on chromosome 1 of Brachypodium distachyon encodes a protein with Piwi and Argonaute domains, including PAZ and RNaseH-like folds, and is annotated with diverse molecular functions such as siRNA and miRNA binding, histone ubiquitin ligase activity, and DNA-binding transcription activator activity. This gene is associated with a wide range of biological processes, including miRNA metabolism, gene silencing by miRNA, somatic stem cell population maintenance, temporal regulation of development, and acropetal auxin transport. It is linked to numerous traits, including photosynthetic ability, lignin biosynthesis, inflorescence and flower development, leaf and root morphology, gibberellic acid and cytokinin content, and responses to UV light and osmotic stress. Studies of related genes in other species connect the family to shoot apical meristem function, leaf polarity, drought stress response, antiviral immunity, grain yield, and reproductive development.
