ABI5 — Brassica juncea

Summary

BJUA04G23060S (ABI5) on chromosome A04 of Indian mustard (Brassica juncea) encodes a bZIP transcription factor of the BZIP46-like family, with sequence-specific DNA binding and transcription cis-regulatory region binding activities. The gene is associated with abscisic acid (ABA) signaling and upregulation of ABA-mediated signaling, as well as responses to abiotic stimuli including salinity, cold, and thirst. It is linked to seed germination, seedling development, pollen maturation, and regulation of DNA-templated transcription. The encoded protein localises to the nucleus and exhibits protein homodimerization activity. ABI5 is also associated with the trait SALTTL. Studies of related genes in other species connect the family to seed dormancy.
