Lineage-specific expansions of ortholog groups between D. noxia and A. pisum, including ortholog groups unique to each species. The number of proteins contained within each ortholog group in A. pisum was subtracted from the number of proteins in the identical ortholog group in D. noxia. Negative numbers indicate lineage-specific expansions in D. noxia, and positive numbers indicate lineage-specific expansions in A. pisum.
