The gene cortex controls mimicry and crypsis in butterflies
2016年6月1日 · Wing colour patterning of multiple species in the butterfly genus Heliconius is controlled by differential expression of the gene cortex, a member of a conserved family of cell cycle regulators.
Mimicry in butterflies: co‐option and a bag of magnificent ...
2017年9月14日 · Butterfly wing patterns are key adaptations that are controlled by remarkable developmental and genetic mechanisms that facilitate rapid evolutionary change. With swift advancements in the fields of genomics and genetic manipulations, identifying the regulators of wing development and mimetic wing patterns has become feasible even in nonmodel ...
optix Drives the Repeated Convergent Evolution of Butterfly Wing …
2011年7月21日 · Here, we characterize one of the major genes responsible for mimetic wing pattern evolution in Heliconius butterflies. Mapping, gene expression, and population genetic work all identify a single gene, optix, that controls extreme red wing pattern variation across multiple species of Heliconius.
Tracing the origin and evolution of supergene mimicry in butterflies
2017年11月7日 · Nature Communications - Wing pattern mimicry in the butterfly Papilio polytes is controlled by a single Mendelian locus, the mimicry supergene doublesex. Here, Zhang and colleagues...
Butterfly genome reveals promiscuous exchange of mimicry
2012年5月16日 · Using genomic resequencing, we show hybrid exchange of genes between three co-mimics, Heliconius melpomene, Heliconius timaretaand Heliconius elevatus, especially at two genomic regions that...
A major gene controls mimicry and crypsis in butterflies and moths
In Hn it modulates black, yellow and orange elements on both wings (HnP), producing phenotypes that mimic butterflies in the genus Melinaea. Morphs/races of Heliconius species included in this study are shown with names.
The Functional Basis of Wing Patterning in Heliconius Butterflies…
Wing-pattern mimicry in butterflies has provided an important example of adaptation since Charles Darwin and Alfred Russell Wallace proposed evolution by natural selection >150 years ago. The neotropical butterfly genus Heliconius played a central ...
Evolution of aposematism and mimicry in butterflies: Causes ...
2019年9月1日 · Here, I review recent genetic and ecological results on Heliconius and Ithomiini butterflies that advance our knowledge on the proximal and ultimate drivers of mimicry, and on the evolutionary and ecological consequences of mimicry in terms of speciation, genetic architecture and ecological niche evolution. I also present recent results that ...
The Heliconius butterflies possess Mullerian mimicry and the Papilio butterflies possess Batesian mimicry. This essay focusses on the differences and the similarities of mimicry in both species, especially of the
Aristaless controls butterfly wing color variation used in mimicry …
2018年11月5日 · Neotropical Heliconius butterflies display a diversity of warningly colored wing patterns which serve roles in both Müllerian mimicry and mate choice behavior. Wing pattern diversity in Heliconius is controlled by a small number of unlinked, Mendelian “switch” loci .
