ADH2 — Brassica juncea

Summary

BJUA06G01380S (BjADH2) encodes an S-nitrosoglutathione reductase (GSNOR) with NADH, NAD+ and NADP+-dependent dehydrogenase activities, also annotated as an aldo-keto reductase and calcium- and zinc-binding protein. The gene is associated with formaldehyde metabolism and catabolism, S-nitrosylation, homeostasis, seed development, heat acclimation and programmed cell death. It has been linked to photosynthetic rate, water use efficiency, drought and salt tolerance, low temperature stress response, leaf senescence, stomatal closure, fertility, pathogen resistance, shade avoidance, root and shoot development, flowering time, silique size, seed production, ammonium toxicity tolerance and thermotolerance. The product localises to plastids, mitochondria, cytosol, plasma membrane and nucleus. Studies of related genes in other species link the family to formaldehyde detoxification, cadmium and iron toxicity tolerance, wounding and salicylic acid responses, systemic acquired resistance, stem branching and trichome branching.
