Data from: Regulation of transposable elements: interplay between TE-encoded regulatory sequences and host-specific trans-acting factors in Drosophila melanogaster
Transposable elements (TEs) are mobile genetic elements that can move around the genome, and their expression is one precondition for this mobility. Because the insertion of TEs in new genomic positions is largely deleterious, the molecular mechanisms for transcriptional suppression have been extensively studied. In contrast, very little is known about their primary transcriptional regulation. Here, we characterize the expression dynamics of TE families in Drosophila melanogaster across a broad temperature range (13–29°C). In 71% of the expressed TE families, the expression is modulated by temperature. We show that this temperature-dependent regulation is specific for TE families and strongly affected by the genetic background. We deduce that TEs carry family-specific regulatory sequences, which are targeted by host-specific trans-acting factors, such as transcription factors. Consistent with the widespread dominant inheritance of gene expression, we also find the prevailing dominance of TE family expression. We conclude that TE family expression across a range of temperatures is regulated by an interaction between TE family-specific regulatory elements and trans-acting factors of the host.
Data from: Cascading reproductive isolation: plant phenology drives temporal isolation among populations of a host-specific herbivore
All organisms exist within a complex network of interacting species, thus evolutionary change may have reciprocal effects on multiple taxa. Here, we demonstrate "cascading reproductive isolation," whereby ecological differences that reduce gene flow between populations at one trophic level affect reproductive isolation (RI) among interacting species at the next trophic level. Using a combination of field, laboratory and common-garden studies and long-term herbaria records, we estimate and evaluate the relative contribution of temporal RI to overall prezygotic RI between populations of Belonocnema treatae, a specialist gall-forming wasp adapted to sister species of live oak (Quercus virginiana and Q. geminata). We link strong temporal RI between host-associated insect populations to differences between host plant budbreak phenology. Budbreak initiates flowering and the production of new leaves, which are an ephemeral resource critical to insect reproduction. As flowering time is implicated in RI between plant species, budbreak acts as a "multitrophic multi-effect trait," whereby differences in budbreak phenology contribute to RI in plants and insects. These sister oak species share a diverse community of host-specific gall-formers and insect natural enemies similarly dependent on ephemeral plant tissues. Thus, our results set the stage for testing for parallelism in a role of plant phenology in driving temporal cascading RI across multiple species and trophic levels.
