PNH — Oryza sativa Indica Group

Summary

BGIOSGA007059 (PNH) of indica rice 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. In rice, PNH is associated with reproductive growth, meiosis, cell division, seed and grain development, plant height, tillering, yield, antiviral immunity, and vascular bundle formation. It is also linked to leaf polarity, shoot apical meristem initiation, auxin signaling, TAS3 tasiRNA biogenesis, and the juvenile-to-adult transition. The gene is associated with traits including panicle length, photosynthetic ability, lignin biosynthesis, gibberellic acid and cytokinin content, and responses to UV light, osmotic stress, and cadmium. Related genes in other species link the family to drought stress response, floral development, and shoot meristem organization.
