PNH — Zea mays

Summary

ZM00001EB217290, also known as PNH, encodes Argonaute108, a protein containing Piwi, PAZ, and RNaseH-like domains characteristic of the Argonaute family. It is associated with siRNA and miRNA binding, gene silencing by miRNA-directed mRNA cleavage, and the regulation of cellular localization, somatic stem cell population maintenance, and temporal development. The gene has been linked to drought stress response, leaf polarity and morphology, virus resistance, auxin signaling, and the juvenile-to-adult transition. Associations with agronomic traits include ear weight, inflorescence branching, photosynthetic ability, lignin biosynthesis, rolled leaf, and root phototropism. Studies of related genes in other species connect the family to shoot apical meristem formation, meiosis, grain yield, and antiviral immunity.
