Abstract

To find key genes essential for salt tolerance in the mangrove plant, Bruguiera sexangula, functional screening was performed using Escherichia coli as the host organism. A transformant expressing a cytosolic chaperonin-containing TCP-1{alpha} (CCT{alpha}) homologue displayed enhanced salt tolerance. Analysis in E. coli of the functional region revealed that a sequence of only 218 amino acids, containing the apical domain, is necessary for osmotolerance. Furthermore, this domain shows chaperone activity in vitro. Therefore, CCT{alpha} facilitates the folding of proteins without ATP or the cage-like structure, and may play an important role in stress tolerance, at least in B. sexangula.
