Genetic Underpinnings Of Novel Trait Development In A Euwallacea-Fusarium Mutualism, Elaina J. Spahr

Graduate Theses, Dissertations, and Problem Reports

Evolutionary Developmental Biology seeks to answer fundamental questions about the mechanisms underlying the evolution and innovation towards increasing structural complexity within the body plan. The ambrosia symbiosis, a polyphyletic group of xylem-feeding beetles, provides a wealth of diversity in novel pouch-like structures called mycangia. This diversity could serve as a rich model for understanding how mutualisms may prompt structural innovation and diversification in a host organism. The ambrosia symbiosis has become a fast-growing research subject in entomology and forest pathology but has yet to experience the same attention under the lens of evolutionary developmental genetics.

Development of mycangia was examined …
