HSP70 — Nicotiana attenuata

Summary

A4A49_65490 (HSP70) in coyote tobacco (Nicotiana attenuata) on scaffold00672 encodes a member of the Hsp70 family of chaperones, with ATP hydrolase activity, ATP binding, and heat shock protein binding functions. It is associated with protein folding and refolding, response to heat, leaf senescence, cell division, defense response, signal transduction, calcium signaling, viral translation, phytochelatin anabolism, and virus-induced PTGS. The gene is linked to chloroplast stroma localization and to related genes HSC-I, HSC-2, and BIP1. Associations with seed weight, seed size, lignin content, stomatal resistance, and chlorophyll content have been noted. Related genes in other species link the family to fruit length and plant height.
