PNH — Nicotiana attenuata

Summary

A4A49_36420 (PNH/AGO5) in Nicotiana attenuata encodes an Argonaute family protein with Piwi, PAZ, and RNaseH-like domains, and is annotated with diverse molecular functions including siRNA binding, RNA endonuclease activity, and histone ubiquitin ligase activity. The gene is associated with miRNA and tasiRNA processing, gene silencing, regulation of epidermis development, somatic stem cell population maintenance, and temporal regulation of development. In this species, AGO7 has been linked to competitive growth. The gene is also associated with leaf polarity and morphology, auxin signalling, virus resistance, and traits including photosynthetic ability, root phototropism, lignin biosynthesis, flower abscission zone morphology, gibberellic acid and cytokinin content, and vegetative growth time. Related genes in other species are linked to seed dormancy, flowering time, and histone ubiquitination.
