IBE (CSIC-UPF): Discovered how a transposable element insertion confers xenobiotic resistance in Drosophila

IBE (CSIC-UPF): Discovered how a transposable element insertion confers xenobiotic resistance in Drosophila


News from IBE (CSIC-UPF)


In the August issue of PLoS Genetics, IBE researchers Lidia Mateo, Anna Ullastres and Josefa Gónzalez report the molecular, biochemical, and phenotypic characterization of an adaptive transposable element insertion. Mapping genotype to phenotype is a challenging task: many phenotypes are affected by a large number of genes and many individual genes affect multiple traits. By combining gene structure, gene expression, protein modelling, enzymatic activity, and phenotypic assays, the researchers were able to show that a previously identified adaptive transposable element insertion mediates xenobiotic resistance in Drosophila. The conservation of stress response pathways across organisms make these results relevant not only for Drosophila but for other organisms as well.
