polyphenol oxidase	m.60893	2703	4.16
reticuline oxidase-like	m.7838	2452	7.1
superoxide dismutase	uniq_01326	1764	5.62
major latex protein (MLP) 28	m.37901	426	2.07
peroxidase 12-like	m.7868	227	2.19
heat shock 70 kDa mitochondrial-like	m.61661	207	0.48

^a Accession numbers of the annotated transcript database of C. majus (version 2 Chmajus2015.01.06) [30] with added cRAP nucleotide sequences (common Random Protein Repository). The searchable Chelidonium majus coding sequence (CDS) database is provided on the IPK Gatersleben ViroBLAST server at: http://webblast.ipk-gatersleben.de/chelidonium/ (accessed on accessed on 24 January 2018). ^b Mascot search probability-based Mowse score. Ion score is −10 × Log(P), where P is the probability that the observed match is a random event. Score values of individual ions greater than 48 indicate the identity or very high homology of the match between the experimental data and the database sequence (p < 0.05). ^c Exponentially modified protein abundance index of identified protein according to Mascot search data, emPAI %—proportion of emPAI values in each category to the sum total of emPAI values for each sample (relative abundance). All proteins identified by MS are provided in Table S2.
