HSFA2 — Glycine max

Summary

GmHSFA2 (GLYMA_14G096800V4) encodes a heat shock transcription factor with HSF-type DNA-binding and winged helix-turn-helix domains, annotated with DNA-binding transcription factor activity, heat shock protein binding, transcription corepressor activity, and RNA polymerase II cis-regulatory region sequence-specific DNA binding. In soybean, it is associated with cellular thermotolerance, the cellular response to heat, the unfolded protein response, the ascorbate-glutathione cycle, phytoalexin biosynthesis, glucan metabolism, response to hypoxia, and fruit and gametophyte development. It localizes to the nucleus, cytosol, cytoplasm, plasmalemma, Golgi complex, and plant-type cell wall. The gene is linked to seed yield, drought tolerance, salt tolerance, high temperature stress response, oxidative stress response, flowering time, disease tolerance, abscisic acid content and sensitivity, and starch grain synthesis. Related genes in other species are associated with acquired thermotolerance, heat tolerance, drought resistance, water productivity, and galactinol and raffinose biosynthesis.
