HSP70 — Nicotiana attenuata

Summary

A4A49_62156 (HSP70) in coyote tobacco (Nicotiana attenuata) encodes a heat shock protein 70 family member, with ATP hydrolase activity, ATP binding, heat shock protein binding, and protein folding chaperone activities. It is associated with protein folding, protein refolding, response to heat, defense response, signal transduction, calcium signaling, cell division, leaf senescence, viral translation, phytochelatin anabolism, and virus-induced PTGS. The protein localizes to the chloroplast stroma. This gene has been associated with seed weight, seed size, lignin content, stomatal resistance, and chlorophyll content. Studies of related genes in other species link the family to fruit length and plant height.
