SR1 — Nicotiana attenuata

Summary

A4A49_21622 (SR1, also known as CMTA2) in coyote tobacco (Nicotiana attenuata) encodes CMTA2, a protein containing CG-1, IQ, and ankyrin repeat domains, and is annotated as a DNA-binding transcription factor and transcriptional co-regulator. This gene is associated with diverse biological processes including cellular response to aluminum, reactive oxygen species anabolism, hydrogen peroxide biosynthetic process, cytokinin metabolism, exocytosis, upregulation of defense response to insect, pigmentation, regulation of anthocyanin anabolism, pistil development, cellular response to cold, response to freezing, and detoxification. It is linked to numerous traits such as total soluble sugar content, fruit quality trait, seed size, flowering time trait, leaf senescence trait, root development trait, anthocyanin content, brassinosteroid content and sensitivity, carotenoid content, and high and low temperature stress response. The gene product localizes to the nucleus, cytosol, cytoplasm, and extracellular space.
