HSP70 — Asparagus officinalis

Summary

A4U43_C07F6410 (AoHSP70) on asparagus chromosome 7 encodes a protein kinase domain-containing protein with an Hsp_70_fam domain, ATPase domain, and ATP hydrolase activity, and is annotated as a protein folding chaperone that binds heat shock proteins. The gene is associated with the endoplasmic reticulum, chloroplast membrane, and cytosol, and is linked to the ERAD pathway, the unfolded protein response, protein refolding, steroidogenesis, lipid metabolism, homeostasis, and responses to heat, stress, and virus. It is associated with thermotolerance, heat stress, wound response, and photosynthetic rate. Studies of related genes in other species link the HSP70 family to heat tolerance in tomato and drought and salt stress tolerance in sugar beet, and to traits including seed weight, plant height, chlorophyll content, and germination rate.
