DREB2 — Brassica juncea

Summary

BjDREB2 (BJUB01G05960S) on Indian mustard chromosome B01 encodes a protein with DNA binding transcription factor activity, transcription cis-regulatory region binding, protein binding, and NAD ADP-ribosyltransferase activity. The gene is associated with responses to abiotic stresses including drought, heat, salinity, osmotic stress, ozone, and oxidative stress, as well as ethylene and jasmonic acid signalling pathways. It is linked to photoperiodic flowering, pollen and embryo development, lateral root morphogenesis, and defence against bacteria. Traits associated with this gene include shoot dry weight, starch content, yield, plant height, root development and thickness, stomatal resistance, cell elongation, meristem identity, and disease tolerance. The protein localises to both the cytoplasm and nucleus. Related genes in other species are linked to stress adaptation, hormone sensitivity, cell death, and root-to-shoot long-distance signalling.
