Pleiotropy Modulates the Efficacy of Selection in Drosophila melanogaster.
Pleiotropy is the well-established idea that a single mutation affects multiple phenotypes. If a mutation has opposite effects on fitness when expressed in different contexts, then genetic conflict arises. Pleiotropic conflict is expected to reduce the efficacy of selection by limiting the fixation of beneficial mutations through adaptation, and the removal of deleterious mutations through purifyi…

Cis-regulatory evolution underlying the changes in wingless expression pattern associated with wing pigmentation of Drosophila.
The co-option of regulatory genes has the potential to play an important role in the evolutionary gain of new traits. However, the changes at the sequence level that underlie such a co-option event are still elusive. We identified the changes in the cis-regulatory sequence of wingless that caused co-option of wingless and led to its expression in new places in Drosophila guttifera, which has uniqu…

Dynamic patterning by the Drosophila pair-rule network reconciles long-germ and short-germ segmentation.
Drosophila segmentation is a well-established paradigm for developmental pattern formation. However, the later stages of segment patterning, regulated by the "pair-rule" genes, are still not well understood at the system level. Building on established genetic interactions, I construct a logical model of the Drosophila pair-rule system that takes into account the demonstrated stage-specific archite…

Evolutionary biology: Co-option and the evolution of morphological novelty.
The molecular mechanisms underlying evolution of morphological novelties are not well understood, although co-option is often inferred. A new study demonstrates that the partial co-option of the trichome gene regulatory network underlies the evolution of novel projections on Drosophila male genitalia.

Wings, horns, and butterfly eyespots: how do complex traits evolve?
Do novel complex traits evolve when pre-existent complex developmental networks are recruited into new places in the body? Here we look closely at the genomic fingerprints that are produced as a result of gene network co-option.

Gene regulatory networks underlying the development and evolution of plasticity in horned beetles.
Horned beetles have emerged as a powerful study system with which to investigate the developmental mechanisms underlying environment-responsive development and its evolution. We begin by reviewing key advances in our understanding of the diverse roles played by transcription factors, endocrine regulators, and signal transduction pathways in the regulation of horned beetle plasticity. We then explo…

HSP90 as a global genetic modifier for male genital morphology in Drosophila melanogaster.
The molecular chaperone protein HSP90 has been proposed to modulate genotype-phenotype relationship in a broad range of organisms. We explore the proposed genetic modifier effect of HSP90 through a genomewide analysis. Here, we show that HSP90 functions as a genetic modifier of genital morphology in Drosophila melanogaster. We identified a large number of single-nucleotide polymorphisms (SNPs) wit…

Making scents of behavioural genetics: lessons from Drosophila.
The expression of behaviours is influenced by many segregating genes. Behaviours are, therefore, complex traits. They have, however, unique characteristics that set them apart from physiological and morphological quantitative traits. First, behaviours are the ultimate expression of the nervous system. This means that understanding the genetic underpinnings of behaviours requires a neurobiological …

Genetic control of a multifunctional trait: The central role of a fatty acid synthase gene in regulating survival and sexual communication.
The genetic basis of multifunctional traits shaped by both natural and sexual selection remains poorly understood. In insects, cuticular hydrocarbons (CHCs) are an excellent example of such traits, providing protection against different micro-climatic conditions while simultaneously encoding cues predominantly used in sexual signaling. The fatty acid synthase (fas) gene family has been implied as …
