Mating strategy predicts gene presence/absence patterns in a genus of simultaneously hermaphroditic flatworms

Evolution, Volume 76, Issue 12, Page 3054-3066, December 2022., 2022
Abstract Gene repertoire turnover is a characteristic of genome evolution. However, we lack well‐replicated analyses of presence/absence patterns associated with different selection contexts. Here, we study ∼100 transcriptome assemblies across Macrostomum, a genus of simultaneously hermaphroditic flatworms exhibiting multiple convergent shifts in ...

Microinjection‐enabled gene silencing in first instar larvae of western flower thrips, Frankliniella occidentalis, reveals vital genes for larval survival

Insect Science, EarlyView.
This study introduces a microinjection technique to deliver dsRNA into the hemolymph of first instar larval thrips (L1s) via the foreleg coxa, enhancing survival rates by minimizing internal tissue damage. Significant knockdown of V‐ATPase‐B, CYP3653A2, and ApoLp‐II/I was achieved, with silencing of CYP3653A2 or ApoLp‐II/I increasing larval mortality ...

Multigenerational downregulation of insulin/IGF‐1 signaling in adulthood improves lineage survival, reproduction, and fitness in Caenorhabditis elegans supporting the developmental theory of ageing

Evolution, Volume 76, Issue 12, Page 2829-2845, December 2022., 2022
Abstract Adulthood‐only downregulation of insulin/IGF‐1 signaling (IIS), an evolutionarily conserved pathway regulating resource allocation between somatic maintenance and reproduction, increases life span without fecundity cost in the nematode, Caenorhabditis elegans.

Differential regulation of the Drosophila sleep homeostat by circadian and arousal inputs. [PDF]

, 2019
One output arm of the sleep homeostat in Drosophila appears to be a group of neurons with projections to the dorsal fan-shaped body (dFB neurons) of the central complex in the brain.

Differential gene expression in Chorthippus parallelus (Zetterstedt, 1821) (Orthoptera: Acrididae: Gomphocerinae) induced by Wolbachia infection

Insect Science, EarlyView.
Distinct lineages of the grasshopper Chorthippus parallelus (Orthoptera: Acrididae) form a well‐known hybrid zone (HZ) in the Pyrenees mountain range; the Iberian endemism C. p. erythropus (Cpe) and the subspecies C. p. parallelus, (Cpp) widely distributed throughout the rest of Europe. Both subspecies differ in diverse traits, including the strains of

Winter fruit contribution to the performance of the invasive fruit fly Drosophila suzukii under different thermal regimes

Insect Science, EarlyView.
Highlights: The contribution of winter and early spring‐available fruit (Aucuba japonica, Elaeagnus ×submacrophylla, and Viscum album) to the performance of D. suzukii depended on their P:C ratio and biophysical properties Even though D. suzukii performance was the lowest in A.
