ABI5 — Brassica juncea

Summary

BJUB06G50070S, the ABI5 gene on chromosome B06 of Indian mustard (Brassica juncea), encodes a bZIP transcription factor of the BZIP46-like family with sequence-specific DNA binding, transcription cis-regulatory region binding, protein homodimerization activity, and DNA binding transcription factor activity. It is associated with abscisic acid (ABA) signaling, including upregulation of ABA-mediated signaling, and responses to thirst, cold, and salinity, as well as activation of the salinity response. The gene is linked to seed germination, pollen maturation, seedling development, and regulation of DNA-templated transcription. It localizes to the nucleus and has been connected to the SALTTL trait. Studies of related genes in other species, including ABI5, ABF1, ABF2, and ABA1, link the family to ABA-mediated stress responses and developmental processes.
