HSC-2 — Camelina sativa

Summary

CSA01G013670 (HSC-2, CsHSP70) encodes a member of the Hsp70 family of molecular chaperones, characterized by an N-terminal ATPase domain and a C-terminal peptide-binding domain, and is annotated with DXP-synthase activity, preprotein binding, and chaperone functions. In Camelina sativa, this gene is associated with diverse biological processes including the MEP pathway, RuBisCO assembly, chloroplast protein import, de-etiolation, guard cell fate commitment, and responses to salicylic acid, low humidity, and chlorate. It is linked to numerous agronomic traits such as biomass yield, photosynthetic rate, plant height, drought tolerance, disease tolerance, leaf senescence, root development, and responses to high and low temperature stress. Associations with salt tolerance, chilling tolerance, immune response, and salicylic acid signaling have also been noted. Studies of related genes in other species link the family to heat stress tolerance, leaf senescence, immunity, and photosynthetic capacity.
