Research Abstract

In response to cold, E.coli produces cold shock proteins (CSPs) that have essential roles in cold adaptation as RNA chaperones. In this study, we demonstrate that Arabidopsis COLD SHOCK DOMAIN PROTEIN 3 (AtCSP3) also functions as an RNA chaperone and regulates expression of stress resistance genes through formation of multiple complexes.
