Alternative splicing in Amphimedon queenslandica. A) Graphical depiction of AS event classes in relation to the canonically spliced isoform (black). From top to bottom: intron retention (IntRt - blue), alternative terminal exon (AltTEx - orange), alternative acceptor (AltAc - yellow), alternative donor (AltDo - green), exon-skipping (ExSk – light green), intron end (IntEnd - light orange) and intron start (IntSt - violet). The number of transcripts in each class of AS is shown in the second column and the percentage of all transcripts this represents is shown in parentheses. The total percentage is over 100% as different types of AS sometimes occur in the same transcript. B) Pie chart showing percentage of AS events belonging to the classes shown in panel A. C) Number of transcripts (y-axis) and percentage (number above each bars) of transcripts with AS events (x-axis) exemplified in panel A. Similar to panel A, the total percentage is over 100% as different types of AS events can occur in the same transcript. Colour coding and abbreviations in B and C are identical to those used in panel A.
