Figure 3From: Screening synteny blocks in pairwise genome comparisons through integer programmingKs distributions for gene pairs before and after QUOTA-ALIGN. Quota-based screening for our test cases: (A) A. thaliana - A. lyrata comparison; (B) A. thaliana - poplar comparison. In both cases, gene pairs that are derived from more ancient duplications were eliminated after QUOTA-ALIGN.Back to article page
