CR88 — Pisum sativum

Summary

PsCR88 (CR88, HSP90C) encodes an ATP-dependent protein folding chaperone belonging to the Hsp90 family, with domains including HSP90_C, Hsp90_N, and HATPase, and exhibits ATP hydrolase, ubiquitin-protein transferase, and cis-trans proline isomerase activities. This gene is associated with thylakoid membrane organization, photorespiration, de-etiolation, and chloroplast stroma protein import, and localizes to the chloroplast inner membrane, thylakoid, nucleoid, Tic complex, and stress granules. It is linked to traits including drought tolerance, high temperature stress response, salt tolerance, bacterial disease response, seed growth and development, root morphology, and vegetative to reproductive phase transition. Studies of related genes in other species connect the family to plastid development, chloroplast protein import, embryogenesis, photosynthesis, fertility, and broad-spectrum disease resistance.
