HSP70 — Brassica napus

Summary

BnHSP70 (DARMORV10_C01P52600.1) on chromosome C01 encodes a member of the heat shock protein 70 family, a chaperone with ATPase and preprotein-binding activities, and is annotated with DXP-synthase, salicylic acid-binding, and SUMO transferase functions. In oilseed rape, this gene is associated with diverse processes including the MEP pathway, RuBisCO assembly, ERAD, chloroplast protein import, de-etiolation, and defense responses to oomycetes and salicylate. It is linked to traits such as seed weight, biomass yield, photosynthetic rate, plant height, leaf senescence, and responses to high and low temperature, oxidative stress, and disease. Associations with salt tolerance, chilling tolerance, nitrogen remobilization, immune response, and salicylic acid signaling have also been noted. Studies of related genes in other species connect the HSP70 family to heat stress tolerance, photosynthesis, leaf senescence, and immunity.
