Abstract Background A major challenge of modern biology is to understand the networks of interacting genes regulating complex traits and the subset of these genes that affect naturally occurring quantitative genetic variation. Previously we used P-element mutagenesis and quantitative trait locus QTL mapping in Drosophila to identify candidate genes affecting resistance to starvation stress and variation in resistance to starvation stress between the Oregon-R Ore and 2b strains. Here we tested the efficacy of whole-genome transcriptional profiling for identifying genes affecting starvation stress resistance. Results We evaluated whole-genome transcript abundance for males and females of Ore 2b and four recombinant inbred lines derived from them under control and starved conditions. There were significant .
