From DNA to fitness differences: sequences and structures of adaptive variants of Colias phosphoglucose isomerase (PGI)Christopher W Wheat
Department of Biological Sciences, Stanford University, USA
Mol Biol Evol 23:499-512. 2006..This study provides novel views of molecular-structural mechanisms, and beginnings of historical evidence, for a long-persistent balanced enzyme polymorphism at PGI in these and perhaps other species...
X-tox: an atypical defensin derived family of immune-related proteins specific to LepidopteraPierre Alain Girard
Ecologie Microbienne des Insectes et Interactions Hôte Pathogène, Universite de Montpellier II, 34095 Montpellier, France
Dev Comp Immunol 32:575-84. 2008..Altogether, these results suggest that although X-tox proteins are derived from defensins, they may play a different and still unknown role in Lepidoptera immune response...- Immune system responses and fitness costs associated with consumption of bacteria in larvae of Trichoplusia niDalial Freitak
Max Planck Institute for Chemical Ecology, Department of Entomology, Hans Knoell Strasse 8, 07745 Jena, Germany
BMC Biol 5:56. 2007..Here, we examine the immune system response and consequences of exposing a lepidopteran agricultural pest to non-infectious microorganisms via simple oral consumption... - The genetic basis of a plant-insect coevolutionary key innovationChristopher W Wheat
Max Planck Institute for Chemical Ecology, Beutenberg Campus, Hans Knoell Strasse 8, 07745 Jena, Germany
Proc Natl Acad Sci U S A 104:20427-31. 2007..Moreover, these mechanistic insights provide the tools for detailed molecular studies of coevolution from both the plant and insect perspectives... 
A mitochondrial-DNA-based phylogeny for some evolutionary-genetic model species of Colias butterflies (Lepidoptera, Pieridae)Christopher W Wheat
Department of Biological Sciences, 371 Serra Mall, Stanford University, Stanford, CA 94305 5020, USA
Mol Phylogenet Evol 47:893-902. 2008..This emerging Colias phylogeny facilitates comparisons of genetic polymorphism and other adaptive mechanisms among taxa, thereby connecting micro- and macro-evolutionary processes...- Microevolutionary dynamics of a macroevolutionary key innovation in a Lepidopteran herbivoreHanna M Heidel-Fischer
Department of Entomology, Max Planck Institute for Chemical Ecology, Jena, Germany
BMC Evol Biol 10:60. 2010..Previous work documents the macroevolutionary and historical ecological importance of the nitrile-specifier protein (Nsp), which facilitated the host shift of Pieridae butterflies onto Brassicales host plants approximately 80 Myr ago... - Evolutionary origins of a novel host plant detoxification gene in butterfliesHanna M Fischer
Department of Entomology, Max Planck Institute for Chemical Ecology, Beutenberg Campus, Jena, Germany
Mol Biol Evol 25:809-20. 2008.... - Rapid transcriptome characterization for a nonmodel organism using 454 pyrosequencingJ Cristobal Vera
Department of Biology, 208 Mueller Laboratory, Pennsylvania State University, University Park, PA 16802, USA
Mol Ecol 17:1636-47. 2008..This development narrows the gap between approaches based on model organisms with rich genetic resources vs. species that are most tractable for ecological and evolutionary studies... - Accessing the transcriptome: how to normalize mRNA poolsHeiko Vogel
Department of Entomology, Max Planck Institute for Chemical Ecology, Jena, Germany
Methods Mol Biol 772:105-28. 2011..This will provide coding gene information across thousands of genes from any organism, providing rapid insights into topics such as gene family member identification and genetic variation that may be associated with a studied phenotype...
