PNH — Zea mays

Summary

ZM00001EB020470, also known as PNH, RGD2, ZIP, and several AGO1 homologs, encodes a protein containing Piwi, PAZ, and RNaseH-like domains. The gene is associated with siRNA and miRNA binding, as well as histone ubiquitin ligase and deubiquitinase activities. In maize, PNH is linked to drought stress response and vasculogenesis, and has been connected to leaf polarity, leaf morphology, auxin signaling, and virus resistance. It is also associated with traits including leaf width and length, ear weight, inflorescence branching, photosynthetic ability, lignin biosynthesis, cadmium concentration, and root phototropism. Studies of related genes in other species link the family to shoot apical meristem formation, reproductive development, grain yield, and antiviral immunity, as well as sexual reproduction and antioxidant activity.
