Rapidly developing functional genomics in ecological model systems via 454 transcriptome sequencingChristopher W Wheat
Metapopulation Research Group, Department of Biological and Environmental Sciences, University of Helsinki, P O Box 65, Viikinkaari 1, Helsinki 00014, Finland
Genetica 138:433-51. 2010..How to use species with genomic resources to inform study of those without is also discussed. In closing, some of the drawbacks of 454 sequencing are presented along with future prospects of this technology...
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...- Nucleotide polymorphism at a gene (Pgi) under balancing selection in a butterfly metapopulationChristopher W Wheat
Department of Biological and Environmental Sciences, University of Helsinki, Finland
Mol Biol Evol 27:267-81. 2010..cinxia and the unrelated Colias eurytheme butterfly suggests a similar but not identical target of balancing selection. Our results indicate convergent evolution between these two species at both the phenotypic and molecular levels... - 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

Department of Biological and Environmental Sciences, University of Helsinki, Helsinki, Finland
Methods Mol Biol 772:129-44. 2011..Our hope is that with greater attention focused upon assessing assembly performance, advances in transcriptome assembly will increase as prices continue to drop and new technologies, such as Illumina sequencing, start to be used... - 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...
