One-to-one orthologs between Danaus plexippus and other insect species

Ortholog identification was performed between the gene models annotated in Danaus plexippus, Bombyx mori, and Drosophila melanogaster. The D. plexippus sequences are from an assembly obtained from an individual that belonged to a monarch population found in Irapuato, Mexico. 1-to-1 orthologs were delineated as part of an analysis devised to determining the proportion of gene models with homology support in other Lepidoptera and D. melanogaster, and in relation to a previously published gene annotation of D. plexippus. Additionally, information from 1-to-1 orthologs was used in the process of contig anchoring to the D. plexippus chromosomes and in the examination of the level of macro and microsynteny conservation in relation to B. mori and D. melanogaster.
