HSP70 — Nicotiana attenuata

Summary

A4A49_65793 (HSP70) in coyote tobacco (Nicotiana attenuata) encodes a member of the Hsp70 family of chaperones, with ATP hydrolase activity and heat shock protein binding ability, and is annotated as a protein folding chaperone. The gene is associated with response to heat, protein refolding, leaf senescence, cell division, defense response, signal transduction, calcium signaling, viral translation, virus-induced PTGS, and phytochelatin anabolism. 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 link the family to plant height and fruit length.
