Polyphenisms are adaptations in which a genome is associated with discrete alternative phenotypes in different environments. Little is known about the mechanism by which polyphenisms originate. We show that a mutation in the juvenile hormone-regulatory pathway in Manduca sexta enables heat stress to reveal a hidden reaction norm of larval coloration. Selection for increased color change in response to heat stress resulted in the evolution of a larval color polyphenism and a corresponding change… Expand

Genetic basis of adaptive evolution of a polyphenism by genetic accommodation
TLDR
The larval colour polyphenism was found to be regulated by one sex‐linked gene of major effect and many smaller effect modifier genes, which shows that the mechanism of genetic accommodation relies on genetic changes that are consistent with the current view of the genetic basis of adaptive evolution. Expand
Environment and Genetic Accommodation
TLDR
A mutation in the juvenile hormone regulatory pathway in Manduca sexta enabled heat stress to reveal a hidden reaction norm of larval coloration, caused by an environment-sensitive threshold switch mediated by the endocrine system. Expand
Decoding the architecture and origins of mechanisms for developmental polyphenism.
TLDR
An emerging genetic knowledge of polyphenism is providing precise targets for testing hypotheses of how switch mechanisms are built-out of olfactory, nutrient-sensing, hormone-reception, and developmental and genetic buffering systems-to accommodate plasticity. Expand
Specialization of a polyphenism switch gene following serial duplications in Pristionchus nematodes
TLDR
The approach shows the tractability of reverse genetics in a non-traditional model system to study evolution by gene duplication by inferring the role of gene duplications in producing a switch gene in the nematode P. pacificus. Expand
Specialization of a polyphenism switch gene following serial duplications in Pristionchus nematodes
TLDR
The approach shows the tractability of reverse genetics in a nontraditional model system to study evolution by gene duplication in the nematode P. pacificus, which has a mouthpart polyphenism specialized for alternative diets. Expand
Evolution of developmental plasticity by opposing dosage of signalling-modifying enzymes
TLDR
A genetic explanation for how plastic responses evolve is offered for the nematode Pristionchus pacificus and a recent duplication of seud-1 in a sister species reveals a direct correlation between genomic dosage and the polyphenism threshold. Expand
Genetic accommodation and the role of ancestral plasticity in the evolution of insect eusociality
TLDR
The time is right to incorporate genetic accommodation into models of the evolution of complex traits, armed with new molecular tools and a better understanding of non-genetic heritable elements. Expand
Polyphenism in Insects
TLDR
This work surveys the status of research on some of the best known examples of insect polyphenism, in each case considering the environmental cues that trigger shifts in phenotype, the neurochemical and hormonal pathways that mediate the transformation, the molecular genetic and epigenetic mechanisms involved in initiating and maintaining the poly Phenotype, and the adaptive and life-history significance of the phenomenon.

Segregating Variation in the Polycomb Group Gene cramped Alters the Effect of Temperature on Multiple Traits
TLDR
Analysis of the chromatin regulator crm, identified as a candidate for adaptation of Drosophila melanogaster to northern latitudes, shows that crm contributes to environmental canalization and modulates the effect of temperature on a genomic region encoding Hedgehog and Wingless signaling effectors. Expand
Phenotypic Convergence in Bacterial Adaptive Evolution to Ethanol Stress
TLDR
The phenotype of ethanol tolerance was stably maintained after an environmental change, suggesting that a mechanism of non-genetic memory contributed to at least part of the adaptation process. Expand

Rapid evolution of a polyphenic threshold
TLDR
The results support the view that certain components of the developmental control mechanism that underlie polyphenic development can evolve rapidly in natural populations and may provide important avenues for phenotypic differentiation and diversification in nature. Expand
Developmental mechanisms of threshold evolution in a polyphenic beetle
TLDR
Larval larvae of populations that have evolved a larger threshold body size have to accumulate greater mass to become competent to express the horned morph, are less sensitive to the juvenile hormone (JH) analogue methoprene, and exhibit a delay in the sensitive period for meethoprene relative to other developmental events.

Evolution of the Gene Network Underlying Wing Polyphenism in Ants
TLDR
The expression of several genes within the network within the wing primordia of reproductive (winged) and sterile (wingless) ant castes is conserved in the winged castes of four ant species, whereas points of interruption within thenetwork in theWingless castes are evolutionarily labile. Expand
The Evolutionary Maintenance of Alternative Phenotypes
  • N. Moran

TLDR
Polyphenism may be restricted to circumstances in which the developmental switch occurs during very early development, and the abundance of seasonal polyphenisms in multivoltine organisms suggests that where environments are favorable, developmental systems are often flexible enough for the establishment of simple polyphenism. Expand
The behavioral ecology of threshold evolution in a polyphenic beetle
TLDR
The ecological basis of rapid threshold evolution in exotic populations of the horn-polyphenic dung beetle Onthophagus taurus is examined, and differences in the intensity of both intra- and interspecific competition have contributed to the evolution of divergent thresholds in these populations.

Uncovering cryptic genetic variation
TLDR
It is argued that cryptic genetic variation is pervasive but under-appreciated, recent progress in determining the nature and identity of genes that underlie cryptic genetic effects is highlighted, and future research directions are outlined. Expand

TLDR
The environmental threshold (ET) model is presented, and it is shown that the ET model predicts that across environments differing in only one factor the genetic correlation will be 1.0, supported by data from three wing dimorphic insects. Expand
Hsp90 as a capacitor for morphological evolution
TLDR
It is reported that when Drosophila Hsp90 is mutant or pharmacologically impaired, phenotypic variation affecting nearly any adult structure is produced, with specific variants depending on the genetic background and occurring both in laboratory strains and in wild populations. Expand
Evolutionary Significance of Phenotypic Plasticity in Plants
TLDR
This chapter focuses on evolutionary significance of phenotypic plasticity in plants, indicating that adaptation by plasticity is a widespread and important phenomenon in plants and has evolved differently in different species. Expand
Genetic control of a seasonal morph in Precis coenia (Lepidoptera: Nymphalidae)
TLDR
Eddysteroid injections and reciprocal wing imaginai disk transplant studies between genetic rosa and wild-type strains show that the rosa gene does not affect the endocrine system, but alters the physiological response mechanism that follows the ecdysteroid-sensitive period for linea induction and culminates in the wing-specific synthesis of ommochrome pigments.
