Figure 1.

Comparison of orthologues between individual chromosomes of O. nubilalis and B. mori. 4',6-diamidino-2-phenylindole-stained images (gray pseudo color) of individual pachytene bivalents of O. nubilalis (blue chromosome numbers) show hybridization signals from O. nubilalis BAC probes. Black vertical bars represent orthologous B. mori chromosomes (italic black numbers) based on locations taken from Kaikobase (http://sgp.dna.affrc.go.jp/KAIKObase/). O. nubilalis BAC designations are shown on the right of each chromosome image. Gray letters indicate intrachromosomal rearrangement of localized genes and lack of conserved gene order between O. nubilalis and B. mori. Colored lines show correspondence of orthologues between B. mori and O. nubilalis based on the carrier BAC signals. Note that images of O. nubilalis chromosomes do not reflect true relative sizes because they were taken from different preparations.
