ABI4 — Brassica juncea

Summary

BJUA09G22800S (ABI4) on Indian mustard chromosome A09 encodes an AP2/ERF transcription factor of the ERF subfamily, containing an AP2/ERF domain and a DNA-binding domain superfamily, with sequence-specific DNA binding and transcription cis-regulatory region binding activities. This nuclear protein is associated with abscisic acid signaling, ethylene-mediated signaling, osmotic and salinity responses, response to heat and stress, defense response, and signal transduction. It is linked to cuticle anabolism, upregulation of wax anabolism, and upregulation of transcription. The gene is also associated with salt tolerance (SALTTL). Related genes in other species link the family to abscisic acid and stress signaling pathways.
