Counts are the sum of three biological replications (except RPS2, identified in only two replications). Protein identification required p<0.05 (MOWSE algorithm), minimum two peptides. We were unable to differentiate between AHA1 and AHA2 by mass spectrometry during runs 2 and 3, two PM H+-ATPases. The number of unique peptides identified for each protein is listed. None of these proteins were identified in the negative control (rps2-101c/rin4 knockout line).
