Enhanced tolerance against salt-stress and freezing-stress of Escherichia coli cells expressing algal bbc1 gene.
The expression of the eukaryotic bbc1 (breast basic conserved) gene (the bbc1 gene of the marine green alga Chlamydomonas sp. W-80 strain) enhanced the tolerance against salt-stress and freezing-stress in E. coli cells. The expression of the BBC1 protein in the E. coli cells carrying the algal bbc1 gene and that in the Chlamydomonas W-80 cells were examined by Western blotting analysis. The result suggests that the eukaryotic BBC1 protein expressed in the E. coli cells has a protective function against the cellular dehydration.
