Trinity transcripts refer to the initial number of transcripts in the Trinity assembly, which were then filtered for those containing the longest open reading frames. The translation of these transcripts was then annotated with BLASTP against the Swiss-Prot database and the number of hits to unique Swiss-Prot entries was recorded; if more than one transcript matched the same Swiss-Prot entry then the longest and most significant match was retained. A CEGMA analysis was conducted to evaluate the coverage of Core Eukaryotic Genes with complete coverage representing the proportion of CEGs with “complete” matches and the total coverage representing the percentage of CEGs that had complete or partial matches in the transcriptome
