  1. a) Accession numbers are from the NCBInr and in-house P. vexillosa transcriptomic databases. b) For positive identification, the score had to be over the significance threshold (p < 0.05). c) Observed (Obs.) MW and pI values were estimated from 2-DE gels and Theoretical (Theo.) MW and pI values were derived from a database search by MASCOT. PM: number of peptides matching the protein sequence; SC: sequence coverage.
