Additional file 3 of Comparative and functional genomics of the ABC transporter superfamily across arthropods

Additional file 3: Figure S3. A comparison was made among the non-variable ABC families (ABC-BH, ABC-D, ABC-E, and ABC-F) with family size (y-axis) broken down by both taxonomic order (x-axis) and family (panels). Orders are color coded, and boxplots include a horizontal black bar for median, boxes for upper quartiles, dots for outliers. Lower case letters above the boxes signify statistical groups generated by the Kruskal-Wallis test.
