Biased Fractionation following the Bl-m-WGD Event in Buckler Mustard.
Fine-scale CCP along GBs A, E, and U is associated with the distribution of retained Bl-m-duplicates in the transcriptome. Transcriptome data are presented on the left of each GB, with the density of transcripts (dens) and of retained duplicates (dupl) as well as evidence of weak (light red) to strong (dark red) purifying selection (sel) along retained duplicates. Using CCP, the longest and most fluorescent GB copy was labeled as #1, and pachytene chromosomes (shown at the bottom) were straightened and displayed alongside the transcriptome data according to differentially painted sub-blocks (Supplemental Data Set 1).
