Teleogryllus oceanicus (field cricket) wing bud proteomics: iTRAQ data


ABSTRACT: In Hawaii, a rapidly-evolving mutation in the field cricket Teleogryllus oceanicus silences males by interfering with the development of sound-producing structures on their forewings. The mutation is called flatwing (fw), and it persists because of natural selection imposed by an acoustically-orienting parasitoid. We examined gene expression differences between wild-type and mutant crickets, focusing on juvenile wing buds. We profiled mRNA expression levels using RNA-seq, and characterized the wing bud proteome using quantitative mass spectrometry.

A major advance in modern evolutionary biology is the ability to start linking phenotypic evolution in the wild with genomic changes that underlie that evolution. We capitalized on a rapidly evolving Hawaiian population of crickets (Teleogryllus oceanicus) to test hypotheses about the genomic consequences of a recent Mendelian mutation of large effect which disrupts the development of sound-producing structures on male forewings. The resulting silent phenotype, flatwing, persists because of natu  ...[more]
