杂交和基因渗入在进化上的重要性一直争论不休。我们使用基因组工具来研究Heliconius的基因渗入，Heliconius是一种快速辐射的新热带蝴蝶属，广泛用于生态学，行为，模仿和物种形成的研究。为了研究鳞翅目Heliconius melpomene的染色体进化以及Heliconius属多个种和小种之间的基因流动，我们对Heliconius melpomene的基因组进行了测序，并将其与其他类群进行了比较。在12，657个预测的Heliconius基因中，化学感受和Hox基因家族的生物学重要扩展特别值得注意。自白垩纪以来，染色体组织一直保持着广泛的保守性，当时蝴蝶从丝绸血统中分离出来。利用基因组重测序，我们发现了三个共模拟物之间的杂交基因交换，H。melpomene，H. timareta和H. elevatus，特别是在两个基因组区域，控制模仿模式。密切相关的Heliconius物种清楚地交换保护色模式基因混杂，这意味着杂交在适应性辐射中的重要作用。
The evolutionary importance of hybridization and introgression has long been debated. We used genomic tools to investigate introgression in Heliconius, a rapidly radiating genus of neotropical butterflies widely used in studies of ecology, behaviour, mimicry and speciation . We sequenced the genome of Heliconius melpomene and compared it with other taxa to investigate chromosomal evolution in Lepidoptera and gene flow among multiple Heliconius species and races. Among 12,657 predicted genes for Heliconius, biologically important expansions of families of chemosensory and Hox genes are particularly noteworthy. Chromosomal organisation has remained broadly conserved since the Cretaceous, when butterflies split from the silkmoth lineage. Using genomic resequencing, we show hybrid exchange of genes between three co-mimics, H. melpomene, H. timareta, and H. elevatus, especially at two genomic regions that control mimicry pattern. Closely related Heliconius species clearly exchange protective colour pattern genes promiscuously, implying a major role for hybridization in adaptive radiation.
