The complex, geometric colour patterns of many animal bodies have important roles in behaviour and ecology. The generation of certain patterns has been the subject of considerable theoretical exploration, however, very little is known about the actual mechanisms underlying colour pattern formation or evolution. Here we have investigated the generation and evolution of the complex, spotted wing pattern of Drosophila guttifera. We show that wing spots are induced by the Wingless morphogen, which… 

Figures and Topics from this paper

Wingless and aristaless2 define a developmental ground plan for moth and butterfly wing pattern evolution.
TLDR
This study describes for the first time a novel Lepidoptera-specific homeobox gene, aristaless2 (al2), which precedes wg expression during the early determination of DII stripe patterns, suggesting homology of these pattern elements across moths and butterflies.
Diversification of complex butterfly wing patterns by repeated regulatory evolution of a Wnt ligand
TLDR
Linkage mapping, gene-expression analysis, and pharmacological treatments all indicate that cis-regulatory evolution of the WntA ligand underpins discrete changes in color pattern features across the Heliconius genus.
Mechanism of Color Pattern Formation in Insects
TLDR
A comprehensive model to explain general color pattern formation in insects and validation with empirical data is required is required.
Blending of animal colour patterns by hybridization
TLDR
It is shown that complex and camouflaged animal markings can be formed by the 'blending' of simple colour patterns, suggesting an unexplored evolutionary process by means of 'pattern blending', as one of the possible mechanisms underlying colour pattern diversity and hybrid speciation.
Wnt signaling underlies evolution and development of the butterfly wing pattern symmetry systems.
TLDR
The first molecular characterization of symmetry system development is presented by showing that WntA expression is consistently associated with the major basal, discal, central, and external symmetry system patterns of nymphalid butterflies, suggesting a role for Wnt signaling in color pattern induction.
A new A-P compartment boundary and organizer in holometabolous insect wings
TLDR
This work shows an additional A-P axis of symmetry running between wing sectors 3 and 4 in Vanessa butterflies, suggesting that this additional compartment boundary and its associated developmental organizer create an axis of wing colour pattern symmetry and a gene expression-based combinatorial code, permitting each insect wing compartment to acquire a unique identity and allowing for the individuation of butterfly eyespots.
Giving eyespots a shiner: Pharmacologic manipulation of the Io moth wing pattern
TLDR
While the cold shock had little to no effect on wing pattern, the aberrations resulting from heparin injections were moderate to profound and depended on the dose and the stage at which injection was made, suggesting a possible link between genetic controls of these elements.
The evolutionary origination of a novel expression pattern through an extreme heterochronic shift
TLDR
The evolutionary history of a novel expression pattern of the yellow gene within the Zaprionus genus of fruit flies is elucidated, highlighting how novel domains of gene expression may arise by extreme shifts in timing during the origins of novel traits.
The regulation of a pigmentation gene in the formation of complex color patterns in Drosophila abdomens
TLDR
The molecular mechanisms that induce the pigmentation gene yellow in a complex spot and shade pattern on the abdomen of the quinaria group species Drosophila guttifera are investigated, showing that the y expression pattern is controlled by only one CRM, which contains a stripe-inducing CRM at its core.
optix Drives the Repeated Convergent Evolution of Butterfly Wing Pattern Mimicry
TLDR
The results show that the cis-regulatory evolution of a single transcription factor can repeatedly drive the convergent evolution of complex color patterns in distantly related species, thus blurring the distinction between convergence and homology.

Pattern formation and eyespot determination in butterfly wings.
TLDR
Eyespots, which form from discrete developmental organizers, are marked by Distal-less gene expression, and appear to be generated by a process similar to, and perhaps evolved from, proximodistal pattern formation in insect appendages.
Chance caught on the wing: cis-regulatory evolution and the origin of pigment patterns in Drosophila
TLDR
It is shown that the evolution of this spot involved modifications of an ancestral cis-regulatory element of the yellow pigmentation gene, which has gained multiple binding sites for transcription factors that are deeply conserved components of the regulatory landscape controlling wing development.
The development and evolution of bristle patterns in Diptera.
TLDR
The spatial distribution of sensory bristles on the notum of different species of Diptera is compared and the complex genetic pathways regulating achaete-scute gene expression and bristle pattern in Drosophila melanogaster are reviewed.
Repeated morphological evolution through cis-regulatory changes in a pleiotropic gene
TLDR
It is shown that a male wing pigmentation pattern involved in courtship display has been gained and lost multiple times in a Drosophila clade, demonstrating how the functional diversification of the modular CREs of pleiotropic genes contributes to evolutionary novelty and the independent evolution of morphological similarities.

TLDR
Analysis of a spotted zebra in the light of the model provides evidence that zebra stripes arise from the inhibition rather than the stimulation of melanin; their pattern is thus of white stripes on a black background.
The consequences of ubiquitous expression of the wingless gene in the Drosophila embryo.
TLDR
The phenotype of heatshocked HS-wg embryos resembles the segment polarity mutant naked, suggesting that embryos that overexpress wingless or lack the naked gene enter similar developmental pathways.
Organizing activity of wingless protein in Drosophila
TLDR
It is proposed that wg protein organizes leg pattern along the dorsoventral axis by conferring ventral positional information within the disc.
Reciprocal functions of the Drosophila yellow and ebony proteins in the development and evolution of pigment patterns.
TLDR
It is found that Yellow and Ebony are expressed in complementary spatial patterns that correlate with the formation of an evolutionary novel, male-specific pigment pattern in Drosophila biarmipes wings, providing a developmental and genetic framework for understanding the evolution of melanin patterns.
Two-stage Turing model for generating pigment patterns on the leopard and the jaguar.
TLDR
A Turing reaction-diffusion model is constructed which generates spot patterns of adult leopards and jaguars by tuning parameters of the model in the subsequent phase of patterning.
Direct and Long-Range Action of a Wingless Morphogen Gradient
TLDR
Findings indicate that wild-type Wg acts at long range, up-regulating the transcription of particular target genes as a function of concentration and distance from secreting cells, and is interpreted as evidence that Wg can act directly and at longrange as a gradient morphogen during normal development.
