HSP70 — Brassica napus

Summary

BnHSP70 (HSP70) encodes a heat shock protein 70 family member with ATPase and chaperone activities, including protein folding chaperone, preprotein binding, and DXP-synthase activity. In oilseed rape, this gene is associated with diverse biological processes such as response to chlorate, cell glucose homeostasis, fermentation, RuBisCO assembly, the MEP pathway, de-etiolation, and regulation of salicylic acid-mediated signaling. It is linked to traits including leaf necrosis, reproductive growth time, photosynthetic ability, biomass yield, seed weight, plant height, and responses to high and low temperature stress, oxidative stress, and disease tolerance. The gene is also connected to phenotypes such as salt tolerance, chilling tolerance, immune response, disease resistance, and salicylic acid defense pathway. Related genes in other species link the family to reduced stature, spontaneous cell death, and increased disease resistance.
