Variation in gene expression within and among natural populations

Marjorie F. Oleksiak, Gary A. Churchill, Douglas L Crawford
Nature Genetics
2002

Evolution may depend more strongly on variation in gene expression than on differences between variant forms of proteins. Regions of DNA that affect gene expression are highly variable, containing… (More)

The genomic landscape of rapid repeated evolutionary adaptation to toxic pollution in wild fish

Noah M. Reid, Dina A. Proestou, +9 authors Andrew Whitehead
Science
2016

Atlantic killifish populations have rapidly adapted to normally lethal levels of pollution in four urban estuaries. Through analysis of 384 whole killifish genome sequences and comparative… (More)

Fundulus as the premier teleost model in environmental biology: opportunities for new insights using genomics.

Karen G. Burnett, Lisa J. Bain, +23 authors Douglas L Crawford
Comparative biochemistry and physiology. Part D…
2007

A strong foundation of basic and applied research documents that the estuarine fish Fundulus heteroclitus and related species are unique laboratory and field models for understanding how individuals… (More)

Natural variation in cardiac metabolism and gene expression in Fundulus heteroclitus

Marjorie F. Oleksiak, Jennifer L Roach, Douglas L Crawford
Nature Genetics
2005

Individual variation in gene expression is important for evolutionary adaptation and susceptibility to diseases and pathologies. In this study, we address the functional importance of this variation… (More)

Functional genomics of physiological plasticity and local adaptation in killifish.

Andrew Whitehead, Fernando Espín Gálvez, Shujun Zhang, L. M. Williams, Marjorie F. Oleksiak
The Journal of heredity
2011

Evolutionary solutions to the physiological challenges of life in highly variable habitats can span the continuum from evolution of a cosmopolitan plastic phenotype to the evolution of locally… (More)

FunnyBase: a systems level functional annotation of Fundulus ESTs for the analysis of gene expression

Justin E. Paschall, Marjorie F. Oleksiak, +5 authors Douglas L Crawford
BMC Genomics
2004

While studies of non-model organisms are critical for many research areas, such as evolution, development, and environmental biology, they present particular challenges for both experimental and… (More)

Genomic variation among populations of threatened coral: Acropora cervicornis

Crawford Drury, Knut Dale, +6 authors Marjorie F. Oleksiak
BMC Genomics
2016

Acropora cervicornis, a threatened, keystone reef-building coral has undergone severe declines (>90 %) throughout the Caribbean. These declines could reduce genetic variation and thus hamper the… (More)

Signatures of selection in natural populations adapted to chronic pollution

L. M. Williams, Marjorie F. Oleksiak
BMC Evolutionary Biology
2008

Populations of the teleost fish Fundulus heteroclitus appear to flourish in heavily polluted and geographically separated Superfund sites. Populations from three Superfund sites (New Bedford Harbor,… (More)

Identification of cytochrome P-450 1A (CYP1A) genes from two teleost fish, toadfish (Opsanus tau) and scup (Stenotomus chrysops), and phylogenetic analysis of CYP1A genes.

Hilary G. Morrison, Marjorie F. Oleksiak, Nelson W. Cornell, Mitchell L. Sogin, John J. Stegeman
The Biochemical journal
1995

Cytochrome P-450-mediated responses to environmental challenges are well known in diverse animal taxa, but the evolution of the complex gene superfamily coding for these enzymes is poorly understood.… (More)

Phenotypic plasticity in gene expression contributes to divergence of locally adapted populations of Fundulus heteroclitus.

David Dayan, Douglas L Crawford, Marjorie F. Oleksiak
Molecular ecology
2015

We examine the interaction between phenotypic plasticity and evolutionary adaptation using muscle gene expression levels among populations of the fish Fundulus heteroclitus acclimated to three… (More)
