Figures & Tables

Figure 1:

Comparison between the two chromosome-scale P. pacificus genomes. The dotplots visualize the megabase coordinates of alignments between the P. pacificus PS312 chromosomes (x-axis) and their counterparts in the PS1843 genome (y-axis). The whole genome alignments were generated by the minimap 2 aligner (options: -N 0 -t 6 -x asm5), and the coordinates were extracted from the resulting PAF file. The gray dashed lines mark 52 assembly gaps in the PS1843 genome that were filled with undetermined sequence stretches of 100 nucleotides in length.
