HSP70 — Nicotiana attenuata

Summary

A4A49_62157 (HSP70) in coyote tobacco (Nicotiana attenuata) encodes a member of the Hsp70 family of molecular chaperones, possessing ATP hydrolase activity and ATP binding, and is annotated as a protein folding chaperone with heat shock protein binding activity. The gene is associated with protein refolding, response to heat, defense response, leaf senescence, cell division, signal transduction, viral translation, phytochelatin anabolism, calcium signaling, and virus-induced PTGS. It is linked to chloroplast stroma localization. Associations with seed weight, seed size, lignin content, stomatal resistance, and chlorophyll content have been noted. Studies of related genes in other species connect the family to fruit length and plant height.
