HSP70 — Nicotiana attenuata

Summary

A4A49_40657, symbol HSP70 in coyote tobacco (Nicotiana attenuata) on scaffold04338, encodes a heat shock protein 70 family member with ATP hydrolase activity, ATP binding, and heat shock protein binding, and is annotated as a protein folding chaperone. This gene is associated with protein refolding, response to heat, leaf senescence, cell division, signal transduction, defense response, viral translation, phytochelatin anabolism, calcium signaling, and virus-induced PTGS. It localizes to the chloroplast stroma and is linked to related genes HSC-I, HSC-2, and BIP1. Associations include seed weight, seed size, lignin content, stomatal resistance, and chlorophyll content. Studies of related genes in other species, based on sequence similarity, link the HSP70 family to fruit length and plant height.
