BG1 — Nicotiana attenuata

Summary

A4A49_28305 (BG1) in coyote tobacco (Nicotiana attenuata) encodes a glucan exo-1,3-beta-glucosidase, also annotated with lichenase, cellulase, and glucan endo-1,3-beta-D-glucosidase activities, and belongs to the glycosyl hydrolase family 17. The gene is associated with defense responses to nematodes and fungi, systemic acquired resistance, salicylic acid and ethylene anabolism, JA signaling, brassinosteroid-mediated signaling, response to water and cold, detoxification, cellular homeostasis, and cell death. Its product localizes to the apoplast, plant-type cell wall, vacuole, secretory vesicle, Golgi, cytosol, and mitochondria. BG1 is associated with traits including net photosynthetic rate, quantum yield, transpiration rate, stomatal resistance, carbohydrate content, nitrate uptake, seed maturation, and seedling growth, as well as phenotypes such as anthocyanin accumulation, abscisic acid biosynthesis, phosphate acquisition, and tolerance to drought, salt, dehydration, and biotic stress.
