ABI5 — Brassica juncea

Summary

BJUB01G43840S (ABI5) on chromosome B01 of Indian mustard encodes a bZIP transcription factor of the BZIP46-like family, with sequence-specific DNA binding and protein homodimerization activity. The gene is associated with abscisic acid (ABA) signaling, including upregulation of ABA-mediated signaling and response to ABA, as well as responses to cold, salinity, and thirst. It is associated with seed germination, seedling development, and pollen maturation, and is linked to the trait SALTTL. The encoded protein localizes to the nucleus and is associated with regulation of DNA-templated transcription. Related genes in other species link the family to ABA-responsive transcription and stress signaling.
