“…There are also known genes responsible for wing patterning and development in model organisms such as Drosophila melanogaster, which may be relevant to intra-specific wing polymorphism 58 . While genetic changes often underlie wing polymorphism,epigenetic changes have also been demonstrated between wing morphs in a planthopper (Sogatella furcifera) 59,60 .…”

Wing polymorphism is a prominent feature of numerous insect groups, but the genomic basis for this diversity remains poorly understood. Wing reduction is a commonly observed trait in many species of stoneflies, particularly in cold or alpine environments. The widespread New Zealand stonefly Zelandoperla fenestrata species group (Z. fenestrata, Z. tillyardi, Z. pennulata) contains populations ranging from long-winged (macropterous) to vestigial-winged (micropterous), with the latter phenotype typically associated with high altitudes. The presence of flightless forms on numerous mountain ranges, separated by lowland fully winged populations, suggests wing reduction has occurred multiple times. We use Genotyping by Sequencing (GBS) to test for genetic differentiation between fully winged (n=62) and vestigial-winged (n=34) individuals, sampled from a sympatric population of distinct wing morphotypes, to test for a genetic basis for wing morphology. We found no population genetic differentiation between these two morphotypes across 6,843 SNP loci, however we did detect several outlier loci that strongly differentiated morphotypes across independent tests. This indicates small regions of the genome are likely to be highly differentiated between morphotypes, indicating a genetic basis for morphotype differentiation. These results provide a clear basis for ongoing genomic analysis to elucidate critical regulatory pathways for wing development in Pterygota.

Nilaparvata lugens (stal) is a rice pest and contains long‐winged and short‐winged varieties, called the wing differentiation. This study compared the protein profiles of the two wing‐types in females and two wing‐disc types 5th‐instar females by two‐dimensional electrophoresis analysis. We detected 172 and 174 protein spots in adults and 5th‐instar nymphs, respectively. The number of proteins with higher content in the long‐winged (disc) individuals is much more than that in the short‐winged (disc) individuals. A total of 32 differential protein spots were found, of which 20 were successfully identified. Their main function is about catabolic process, fiber and nucleoside binding, and they constitute 52 protein–protein interactions, which is around the glycolysis as the core. These results enrich the research on the protein Level in wing development, and provide more references for future studies.

“…As the distinct phenotypes of wing-dimorphic species have very similar genetic backgrounds, such taxa present ideal systems for exploring the molecular basis of wing loss. Previous studies of wing-dimorphic species have suggested that wing polymorphism can be genetically determined [23][24][25][26][27], controlled by environmentally driven gene expression (polyphenism; [11,[28][29][30]), include both genetic and environmental components [31], or be under the control of epigenetic factors [32,33].…”

Background: The genetic basis of wing development has been well characterised for model insect species, but remains poorly understood in phylogenetically divergent, non-model taxa. Wing-polymorphic insect species potentially provide ideal systems for unravelling the genetic basis of secondary wing reduction. Stoneflies (Plecoptera) represent an anciently derived insect assemblage for which the genetic basis of wing polymorphism remains unclear. We undertake quantitative RNA-seq of sympatric full-winged versus vestigial-winged nymphs of a widespread wingdimorphic New Zealand stonefly, Zelandoperla fenestrata, to identify genes potentially involved in wing development and secondary wing loss. Results: Our analysis reveals substantial differential expression of wing-development genes between full-winged versus vestigial-winged stonefly ecotypes. Specifically, of 23 clusters showing significant similarity to Drosophila wing development-related genes and their pea aphid orthologues, nine were significantly upregulated in full-winged stonefly ecotypes, whereas only one cluster (teashirt) was substantially upregulated in the vestigial-winged ecotype. Conclusions: These findings suggest remarkable conservation of key wing-development pathways throughout 400 Ma of insect evolution. The finding that two Juvenile Hormone pathway clusters were significantly upregulated in vestigial-winged Zelandoperla supports the hypothesis that Juvenile Hormone may play a key role in modulating insect wing polymorphism, as has previously been suggested for other insect lineages.
