Secrets of butterfly wing patterns revealed by gene hacking New Scientist
Butterfly wings have been given make-overs by scientists who tweaked a "painting gene" to change their patterns and colours. The research has major implications for understanding how the.

Butterfly wing patterns are highly diverse and have complex biological functions. โข Diversification of wing patterns can occur at the intra- or inter-specific level. โข Both genetic and environmental factors can influence wing patterns. โข Diversified wing patterns are a reconciliation of evolution and developmental constraints.

The typical color pattern elements on the wings of most butterfly species and also many moths can be understood as derivatives of the Nymphalid ground plan (Fig. 2).The Nymphalid ground plan was originally proposed by Schwanwitsch and reintroduced into the recent scientific discourse by Nijhout as a paradigm for understanding the development and determining homologies among the patterns found.

Patterns, Genes, and Butterfly Wings National Geographic Education Blog
Butterfly wing patterns derive from a deeply conserved developmental ground plan yet are diverse and evolve rapidly. It is poorly understood how gene regulatory architectures can accommodate both deep homology and adaptive change. To address this, we characterized the cis-regulatory evolution of the color pattern gene WntA in nymphalid.

The study, "Deep cis-regulatory homology of the butterfly wing pattern ground plan," published as the cover story in the Oct. 21 issue of Science, explains how DNA that sits between genes - called 'junk' DNA or non-coding regulatory DNA - accommodates a basic plan conserved over tens to hundreds of millions of years while at the.
Butterfly Wing Patterns
Colorful Wings. The colors and patterns on butterfly wings come from tiny scales. Each scale can contain granules of pigment or have a texture that produces a color or effect. Together, these scales add up like pixels in an image. Each scale attaches individually, allowing them to break off and help butterflies escape from spider webs.

31 Butterflies and moths are masters of disguise, able to copy animal faces, rolled-up leaves and even snakes. Welcome to the kaleidoscopic world of the butterfly wing. How do butterflies and moths (known collectively as Lepidoptera) make use of their vibrant wing patterns? Why are some species experts in camouflage?

Butterfly wing patterns provide a prominent model for studying the development and genetic regulation underlying evolutionary changes. This is because slight shifts in gene expression of a few master genes, such as WntA, affect the expression of several other genes, which can be directly observed as wing color and pattern variations ( 2 - 7 ).

In general, butterflies use the upper surfaces of their wings to seduce the opposite sex, whereas they use the lower surfaces to hide from view or to communicate to their predators that eating them would be toxic. We have identified a gene that is responsible for creating the upper surface "seductive message" patterns.

Butterfly wing patterns are organized along Ground Plans, which are compartments for different intervein pattern elements (Figure 1). These pattern elements include eyespots, ellipses, and midlines. The Ground plan, at least for nymphalids, has three symmetry bands: the basal system closest to the body, the central system, the border system.

Toshio Sekimura, H. Frederik Nijhout. The first book to present the recent genetic and molecular insights into butterfly wing pattern development. Offers an integrative approach to understanding the diversity of butterfly wing patterns. Includes the necessary research fields to analyze the diversity: evo-devo, eco-evo, developmental genetics.
