PNH — Oryza sativa Japonica

Summary

OS03G0800200 (PNH/MEL1) on rice chromosome 3 encodes an Argonaute-family protein containing Piwi, PAZ and RNaseH-like domains, with annotated siRNA and miRNA binding activity and is associated with small RNA-mediated gene silencing. The gene is associated with meiosis, germ cell development, spermatogenesis, and somatic stem cell population maintenance, and is linked to sterility, erect growth, and antiviral immunity. Associations include leaf polarity and morphology, auxin signalling, TAS3 tasiRNA biogenesis, juvenile-to-adult transition, and reproductive growth. The gene is also linked to grain, seed, height, tiller, and vascular bundle traits, as well as amylose content, photosynthetic ability, lignin biosynthesis, and responses to UV light, osmotic stress, and cadmium. Related genes in other species connect the family to developmental timing, floral organ development, and drought stress response.
