PNH — Nicotiana attenuata

Summary

A4A49_34688 (PNH, also known as AGO1B) on coyote tobacco scaffold00950 encodes an Argonaute family protein containing Piwi, PAZ, and RNaseH-like domains, with annotated siRNA binding and RNA endonuclease activity. In this species, the gene is associated with competitive growth, regulation of epidermis development, miRNA and long siRNA processing, gene silencing by miRNA-directed mRNA cleavage, regulation of secondary metabolism and flavonoid biosynthesis, temporal development, and somatic stem cell population maintenance. It is linked to traits including leaf morphology and polarity, virus resistance, auxin signalling, TAS3 ta-siRNA biogenesis, juvenile-to-adult transition, photosynthetic ability, root phototropism, lignin biosynthesis, and responses to UV-A and UV-B light. Related genes in other species are associated with histone ubiquitination, seed dormancy, flowering time, and fungal susceptibility.
