HSFB3 — Phaseolus vulgaris

Summary

PvHSFB3 (PHAVU_007G251900) on French bean chromosome 7 encodes a protein with an HSF-type DNA-binding domain. The gene product exhibits RNA polymerase II cis-regulatory region sequence-specific DNA binding, identical protein binding, and DNA-binding transcription factor activity. PvHSFB3 is associated with cellular response to heat, regulation of transcription by RNA polymerase II, cell death, and DNA-dependent transcription. The protein localises to both the cytoplasm and nucleus. Studies of related genes in other species link the HSFB3 family to seed weight, plant height, and arsenic concentration traits.
