Research Abstract

The transcriptome of an extreme environmental alga were performed under a high temperature, highly-concentrated metal ions, and oxidative stress environment. As a result, the candidates of many stress responsive genes have been identified. The primitive eukaryotic red alga Cyanidioschyzeraonmolehave adapted by the expression of heat shock protein derived from thermophile against heat stress range close to the threshold temperature. The expression patterns of energy metabolism-related genes were also analyzed under oxidative stress environment by using the alga.
