DREB2 — Brassica juncea

Summary

BJUA05G32970S, designated BjDREB2, encodes a protein with an AP2/ERF domain and DNA-binding transcription factor activity, and is annotated with NAD ADP-ribosyltransferase activity. It is associated with responses to abiotic stresses including drought, heat, salt, osmotic stress, ozone, and oxidative stress, as well as with ethylene, abscisic acid, and jasmonic acid signalling pathways. The gene is linked to cuticle and wax biosynthesis, nitric oxide metabolism, photoperiodic flowering, pollen development, and lateral root morphogenesis. Agronomically, BjDREB2 has been connected to yield, shoot dry weight, starch content, plant height, root development traits, stomatal resistance, and disease tolerance. It localises to both the nucleus and cytoplasm. Related genes in other species are linked to stress adaptation, cell death, and hormone sensitivity.
