Transcriptomic analysis in jellyfish polyp under acidified seawater condition

Abstract

The transcriptional impact of ocean acidification in polyp of Aurelia aurita was evaluated using an oligo-microarray which contains oligonucleotide probes of 29,524 unigenes of A. aurita. The polyps were incubated at pH 7.5 condition for 6, 24, and 48 h to predict the biological responses to the acidified condition at transcription level. As the results, we identified 33 differentially expressed genes (DEGs) in 6 h exposed group, 36 DEGs in 24 h exposed group, and 96 DEGs in 48 h exposed group. The metabolic and physiological changes will be predicted and discussed after considering the functional aspects of these DEGs. 24, and 48 h to predict the biological responses to the acidified condition at transcription level.
