PNH — Zea mays

Summary

ZM00001EB050240 (ZmPNH) on maize chromosome 1 encodes a protein with multiple annotated molecular functions including siRNA and miRNA binding, histone ubiquitin ligase and deubiquitinase activities, and DNA-binding transcription activator activity. The gene is associated with diverse biological processes such as sex determination, somatic stem cell population maintenance, miRNA metabolic processes, leaf abscission, and regulation of body size. In maize, ZmPNH has been linked to drought stress response. Associations also include traits like ear weight, photosynthetic ability, inflorescence branching, leaf morphology, root phototropism, and responses to UV light and osmotic stress. Studies of related genes in other species connect the family to shoot apical meristem development, leaf polarity, antiviral immunity, grain yield, and reproductive development.
