Lack of parent-of-origin effects in Nasonia jewel wasp: A replication and extension study

PLoS ONE, 2021
In diploid cells, the paternal and maternal alleles are, on average, equally expressed. There are exceptions from this: a small number of genes express the maternal or paternal allele copy exclusively.

Genetic Basis of Cuticular Hydrocarbon Variation in the Desert Ant <i>Cataglyphis niger</i>. [PDF]

Ecol Evol
Cuticular hydrocarbons (CHCs) are a ubiquitous component of ant cuticles that are used for a wide range of chemical signaling functions, especially recognition. Here we tested for a genetic basis of CHC variation in the desert ant Cataglyphis niger. We applied a genomic mapping approach to discover associations between CHCs and 20 quantitative trait ...

The biological significance of lipogenesis in Nasonia vitripennis [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2022
Parasitic wasps have long been thought to be unable to synthesize fatty acids de novo, but recent 13 C-labelling studies have challenged this view. It remained unclear, however, whether the reported biosynthesis rates are of biological relevance.

Behavioral and spermatogenic hybrid male breakdown in Nasonia [PDF]

Heredity, 2010
Several reproductive barriers exist within the Nasonia species complex, including allopatry, premating behavioral isolation, postzygotic inviability and Wolbachia-induced cytoplasmic incompatibility. Here we show that hybrid males suffer two additional reproductive disadvantages, an inability to properly court females and decreased sperm production ...

Oviposition but not sex allocation is associated with transcriptomic changes in females of the parasitoid wasp Nasonia vitripennis [PDF]

, 2015
This work was supported by Natural Environment Research Council (NERC) grant (NE/J024481/1). DMS was previously funded by a NERC Advanced Research Fellowship.Linking the evolution of the phenotype to the underlying genotype is a key aim of evolutionary ...

Egg Collection for Nasonia (Parasitoid Wasp) [PDF]

Cold Spring Harbor Protocols, 2009
INTRODUCTIONNasonia is a complex of four closely related species of wasps with several features that make it an excellent system for a variety of genetic studies. These include a short generation time, ease of rearing, interfertile species, visible and molecular markers, and a sequenced genome.

The quantitative genetic basis of sex ratio variation in Nasonia vitripennis : a QTL study [PDF]

, 2010
Our understanding of how natural selection should shape sex allocation is perhaps more developed than for any other trait. However, this understanding is not matched by our knowledge of the genetic basis of sex allocation.

Chromosomal anchoring of linkage groups and identification of wing size QTL using markers and FISH probes derived from microdissected chromosomes in Nasonia(Pteromalidae : Hymenoptera) [PDF]

, 2004
Nasonia vitripennis is a small parasitic hymenopteran with a 50-year history of genetic work including linkage mapping with mutant and molecular markers. For the first time we are now able to anchor linkage groups to specific chromosomes.

A sex allocation cost to polyandry in a parasitoid wasp [PDF]

, 2015
R.A.B. is supported by a NERC DTG studentship.The costs and benefits of polyandry are central to understanding the near-ubiquity of female multiple mating. Here, we present evidence of a novel cost of polyandry: disrupted sex allocation.

Dual mode of embryonic development is highlighted by expression and function of Nasonia pair-rule genes

eLife, 2014
Embryonic anterior–posterior patterning is well understood in Drosophila, which uses ‘long germ’ embryogenesis, in which all segments are patterned before cellularization.
