Regulated proteins identified by MS/MS.

The effects of high-CO2 exposure were studied at two temperatures (12°C and 18°C) (n = 12, six controls and six exposed). Spots classified as “up” regulated are those containing increased amounts of protein; spots “down” regulated are those with reduced amounts of protein; spots classified as “high-CO2” are those detected only in the high-CO2 group (but not in the control group). The accession number is an identifier given to the protein according to the NCBI database, and the score is the sum of the unique ion scores. “Pep.” represents number of peptides. Complete protein identification data is available as Table S1, including the specific peptide sequences for each protein. Mann-Whitney U-rank test and p-value ≤0.05.
