DREB2 — Glycine max

Summary

GLYMA_14G056200V4, designated GmDREB2, encodes a protein containing an AP2/ERF domain and a DNA-binding domain superfamily, and is associated with NAD ADP-ribosyltransferase activity, transcription coactivator activity, ubiquitin-protein transferase activity, transcription cis-regulatory region binding, DNA binding, DNA binding transcription factor activity, and protein binding. In soybean, this gene is linked to diverse biological processes including ureide breakdown, zinc import, membrane organization, upregulation of chlorophyll breakdown, actin depolymerization, trichome papilla formation, glucose mediated signalling, response to superoxide, stomatal complex patterning, abscission, protein autoubiquitination, nitric oxide anabolism, organ growth, lateral root morphogenesis, glucosinolate metabolism, upregulation of defense response, and positive regulation of leaf senescence. GmDREB2 is associated with numerous agronomically relevant traits such as yield, seed longevity, germination rate, chlorophyll content, photosynthetic rate, transpiration rate, stomatal resistance, cell membrane stability, water stress response, osmotic response sensitivity, and abiotic plant stress response trait. The gene product localizes to the nucleus, cytoplasm, nucleolus, and RNA polymerase II, IV, and V complexes. Studies of related genes in other species link the family to drought, heat, cold, and salt stress tolerance, as well as tuberization and flavonoid accumulation.
