Concerted evolution reveals co-adapted amino acid substitutions in Na+K+-ATPase of frogs that prey on toxic toads.

Shabnam Mohammadi, Lu Yang, Arbel Harpak, Santiago Herrera‐Álvarez et autres

ABSTRACT Gene duplication is an important source of evolutionary innovation, but the adaptive division-of-labor between duplicates can be opposed by ongoing gene conversion between them. Here we document a tandem duplication of Na + ,K + -ATPase subunit α1 (ATP1A1) shared by …

Epistasis among clustered lineage-specific amino acid substitutions in the Drosophila Trio protein

Flora Borne, Andrew M. Taverner, Peter Andolfatto

Intramolecular epistasis is increasingly recognized as a key factor shaping patterns of evolutionary rate variation among protein sites and constraining adaptive evolution. While genome-wide analyses have revealed that intramolecular epistatic interactions can drive the spatial clustering of amino acid substitutions, direct empirical …

Cis-regulatory evolution of Wnt family genes contributes to a morphological difference between silkworm species

Kenta Tomihara, Ana Pinharanda, Young Mi Kwon, Andrew M. Taverner et autres

Closely related species often exhibit distinct morphologies that can contribute to species-specific adaptations and reproductive isolation. One example is Lepidopteran caterpillar appendages, such as the "caudal horn" of Bombycoidea moths, which have evolved substantial morphological diversity among species in this group. Using …

Admixture Mapping Reveals Evidence for Multiple Mitonuclear Incompatibilities in Swordtail Fish Hybrids

Nemo V. Robles, Benjamin M. Moran, María José Rodríguez Barrera, Gaston I. Jofre et autres

How barriers to gene flow arise between closely related species is one of the oldest questions in evolutionary biology. Classic models in evolutionary biology predict that negative epistatic interactions between variants in the genomes of diverged lineages, known as hybrid incompatibilities, will …

The three-dimensional genome drives the evolution of asymmetric gene duplicates via enhancer capture-divergence

UnJin Lee, Deanna Arsala, Shengqian Xia, Cong Li et autres

Previous evolutionary models of duplicate gene evolution have overlooked the pivotal role of genome architecture. Here, we show that proximity-based regulatory recruitment by distally duplicated genes is an efficient mechanism for modulating tissue-specific production of preexisting proteins. By leveraging genomic asymmetries, we …

Diversifying selection and adaptive introgression of carotenoid-processing genes underlie the evolution of bill color in the long-tailed finch

Daniel M. Hooper, Callum S. McDiarmid, Matthew J. Powers, Nicholas M. Justyn et autres

Abstract Carotenoid pigmentation produces the yellow and red coloration of birds and other vertebrates, but our understanding of the genetic architecture of carotenoid ornamentation is largely limited to studies of novel color variants observed in captively bred populations. The complexity of carotenoid-based …

Patterns of recombination in snakes reveal a tug-of-war between PRDM9 and promoter-like features

Carla Hoge, Marc de Manuel, Mohamed Mahgoub, Naima Okami et autres

In some mammals, notably humans, recombination occurs almost exclusively where the protein PRDM9 binds, whereas in vertebrates lacking an intact PRDM9 , such as birds and canids, recombination rates are elevated near promoter-like features. To determine whether PRDM9 directs recombination in nonmammalian …
