*Final length of BAC assembly after vector sequence was removed and linked contigs were joined with N blocks.
**BAC coverage was calculated by dividing the total number of P20 bases by the total amount of pine sequence in each scaffold assembly. Genomic coverage of WGS reads was determined by dividing the total base pairs by the genome size, 2.2E10 bp.
