title: Genome-wide gene expression profiling in gamma-irradiated green alga, Pseudokirchneriella subcapitata, by HiCEP.
abstract: Transcriptome was analyzed in gamma-irradiated green alga Pseudokirchneriella subcapitata by high coverage gene expression profiling (HiCEP). Approximately 7,800 expressed genes were detected. Expression levels of 623-707 genes were affected at 100-300 Gy. Nucleotide sequences of 41 up-regulated genes were determined. The quantitative reverse transcription polymerase chain reaction validated the up-regulation. Two genes had homology to genes related to ionizing radiation. These results indicate usefulness of HiCEP for screening of stress-responsive genes in species that are ecotoxicologically important but for which genomic sequence information is lacking.
