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.展开更多
