HSFB2B — Cicer arietinum

Summary

HSFB2B (HSF7) on chickpea chromosome 8 encodes a protein with an HSF DNA-binding domain and is annotated for DNA binding transcription factor activity, transcription corepressor activity, RNA Polymerase II cis-regulatory region sequence-specific DNA binding, pigment binding, salicylic acid binding, calcium ion binding, identical protein binding, histidine kinase binding, poly(U) binding, mRNA binding, protein homodimerization activity, protein binding, and sequence-specific DNA binding. The gene is associated with cellular response to heat, regulation of transcription by RNA polymerase II, DNA-dependent transcription, response to low light intensity stimulus, photosynthesis (light harvesting in photosystem I and light reaction), negative regulation of transcription by RNA polymerase II, gibberellic acid homeostasis, embryo shoot apical meristem specification, response to high light intensity, vascular tissue pattern formation, downregulation of gibberellic acid mediated signaling, cellular response to hypoxia, JA signaling, innate immunity, downregulation of transcription, response to auxin, and response to cold. It is linked to traits including high temperature stress response, flowering time, disease tolerance, chlorophyll content, seed dormancy, root morphology, fruit size, and quantum yield. Observed phenotypes include heat stress tolerance, salt stress tolerance, thermotolerance, acquired thermotolerance, pathogen resistance, circadian rhythm, and hypocotyl elongation. The gene is also connected to strigolactone, brassinosteroid, and jasmonic
