Role of nubbin in the development of forewing sound-producing structures in Acheta domesticus (house cricket)
Among insects, Orthoptera (crickets and grasshoppers) have evolved a set of highly specialized structures for acoustic communication, with males engaged in sound production and amplification (stridulation) and females in sound reception. These structures in males are located on their forewings, suggesting that some of the wing genes may have been co-opted for new roles in stridulation. As previous studies have identified nubbin (nub) as one of the key genes in the wing development network, we examined its function in the house cricket, Acheta domesticus. Our results show that nub regulates the overall size and venation of both fore- and hindwings in both sexes, consistent with its general role in wing development. Moreover, in males this gene is also involved in the development of sound resonators (primarily the harp, anal area, mirror, and chord). The distinct morphology of these structures is generated by either the activation (in the harp and anal area) or suppression (in the mirror and chord) of vein and cross-connection development in localized regions of the forewings. Finally, nub RNAi males do not stridulate, confirming that the observed changes in the morphology of resonators are functionally significant and responsible for the loss of sound production.
期刊介绍:
Frontiers in Ecology and Evolution publishes rigorously peer-reviewed research across fundamental and applied sciences, to provide ecological and evolutionary insights into our natural and anthropogenic world, and how it should best be managed. Field Chief Editor Mark A. Elgar at the University of Melbourne is supported by an outstanding Editorial Board of international researchers. This multidisciplinary open-access journal is at the forefront of disseminating and communicating scientific knowledge and impactful discoveries to researchers, academics and the public worldwide.
Eminent biologist and theist Theodosius Dobzhansky’s astute observation that “Nothing in biology makes sense except in the light of evolution” has arguably even broader relevance now than when it was first penned in The American Biology Teacher in 1973. One could similarly argue that not much in evolution makes sense without recourse to ecological concepts: understanding diversity — from microbial adaptations to species assemblages — requires insights from both ecological and evolutionary disciplines. Nowadays, technological developments from other fields allow us to address unprecedented ecological and evolutionary questions of astonishing detail, impressive breadth and compelling inference.
The specialty sections of Frontiers in Ecology and Evolution will publish, under a single platform, contemporary, rigorous research, reviews, opinions, and commentaries that cover the spectrum of ecological and evolutionary inquiry, both fundamental and applied. Articles are peer-reviewed according to the Frontiers review guidelines, which evaluate manuscripts on objective editorial criteria. Through this unique, Frontiers platform for open-access publishing and research networking, Frontiers in Ecology and Evolution aims to provide colleagues and the broader community with ecological and evolutionary insights into our natural and anthropogenic world, and how it might best be managed.
