3. Characterization and evolutionary modeling for adaptive introgression.
1、 Characterizing the genetic basis and evolutionary history of supergene mimicry in Asian swallowtail butterflies
Sex-limited Batesian mimicry in butterflies offers a classic example to study both sex-limited polymorphism and frequency-dependent selection. For decades, the entire female-limited mimetic wing phenotype in Papilio polytes has been considered controlled by a single Mendelian ‘supergene’ but what a supergene is has been debated. We identified the cause of supergene mimicry in P. polytes, and we found the supergene is a single gene, doublesex, a well-known central player involved in insect sex-determination. Moreover, the doublesex mimetic haplotype is maintained within a chromosomal inversion (Kunte et al., Nature, 2014). We also extended this study to the entire polytes species group to trace the origin and evolution of supergene mimicry. Our results suggest that sexual dimorphism and female-limited polymorphism are a result of ancient balancing selection together with independent origins of similar morphs in different lineages and secondary loss of polymorphism in other lineages. In addition, both natural selection and genetic drift might have contributed to the secondary loss of polymorphism (Zhang et al., Nat. Commun., 2017).
2、 Studying introgression, adaptation and speciation in butterflies
The butterfly genus Heliconius offers an excellent system to study hybridization and introgression. We examined the patterns of introgression among closely related species and our results reveal that hybridization tends to reduce the accumulation of pergence at neutral sites (Kronforst et al., Cell Rep., 2013). In addition, we showed a pair of distantly related co-mimetic species maintained their mimetic wing patterns by adaptive introgression and depicted a genome-wide portrait of introgression among distantly related Heliconius species. During this process, we developed an efficient and comprehensive workflow to identify putative introgression signatures (Zhang et al., Genome Biol., 2016). We also studied hybrid speciation in North American swallowtail butterflies. We characterized and inferred genomic mosaicism and identified a variety of targets of adaptive evolution in hybrid species Papilio appalachiensis (Zhang et al., Genome Biol. Evol., 2013).
3、 Developing methods to fully unlock the scientific potential of butterflies
Butterflies have served as important research objects of studies in ecology and evolution. However, their highly heterozygous genomes have hindered them from being fully unlocked as model organisms. We have dedicated our research efforts to performing genome assemblies from highly heterozygous, outbred butterflies and developing precise and efficient genome editing using CRISPR/Cas9. Besides, we also explored evolutionary patterns of genome-wide pergence among three focal butterfly species (Li et al., Nat. Commun., 2015).
4、 Uncovering the genetics of monarch butterfly warning coloration
The monarch butterfly Danaus plexippus is the world’s most famous insect and is particularly well-known because of its massive annual migration across North America and bright warning coloration. By sequencing archived and current D. plexippus samples, we tracked the genetic control of monarch warning coloration into a single gene. This research was as a part of the 101 monarch butterfly genome project (Zhan et al., Nature, 2014).
