Genomics Analysis of L-DOPA Exposure in .

is a dietary specialist fruit fly that evolved from a generalist ancestor to specialize on the toxic fruit of This species pair has been the subject of numerous studies where the goal has largely been to determine the genetic basis of adaptations associated with host specialization. Because one of the most striking features of fruit is the production of toxic volatile compounds that kill insects, most genomic studies in to date have focused on gene expression responses to the toxic compounds in its food. In this study, we aim to identify new genes important for host specialization by profiling gene expression response to 3,4-dihydroxyphenylalanine (L-DOPA).
