Segment - specific expression profiles ofthe 10 most abundantconotoxin contigs. Y - axis: total percent expression for the entire venom - duct broken down by segment. X - axis: toxin ID as in Additional file 2: Table S1, with its annotation and superfamily name shown in parentheses. Expression levels are scaled to the proportion of aligned reads among the whole transcriptome, divided into four segments: Proximal (P), Proximal Central (PC), Distal Central (DC) and Distal (D).
