-
↵The number includes 362 primer pairs ordered for BAC-end derived SSRs and 20 markers selected from the fully-sequenced BACs and PACs.
-
↵The mean number of repeats was calculated for the sequences selected for the primer design.
-
↵The mean GC content in flanking regions was estimated based on a total number of sequences in this class analyzed in this study.
