The diploid species Brassica rapa(genome AA)and B.oleracea(genome CC)were compared by full-scale proteome analyses of seedling.A total of 28.2% of the proteins was common to both species,indicating the existence of a basal or ubiquitous proteome.However,a number of discriminating proteins(32.0%)and specific proteins(39.8%)of the Brassica A and C genomes,respectively,were identified,which could represent potentially species-specific functions.Based on these A or C genome-specific proteins,a number of PCR-based markers to distinguish B.rapa and B.oleracea species were also developed.
