PNH — Nicotiana attenuata

Summary

A4A49_39268 (PNH/AGO10) in coyote tobacco encodes an Argonaute family protein containing Piwi, PAZ, and RNaseH-like domains, with annotated siRNA binding, RNA endonuclease activity, and dsRNA binding. This gene is associated with miRNA and long siRNA processing, gene silencing by miRNA-directed mRNA cleavage, 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 associated with numerous traits including leaf morphology and polarity, virus resistance, auxin signalling, juvenile-to-adult transition, photosynthetic ability, root phototropism, lignin biosynthesis, cytokinin and gibberellic acid content, flower and inflorescence development, seed dormancy and longevity, and responses to UV-A and UV-B light. Related genes in other species link the family to histone ubiquitination, flowering time, and seed dormancy.
