Reconstruction of a rare {triangleup}10 desaturation pathway enables production of yellow peach moth pheromone precursors in Camelina sativa

The paper reconstructs a rare Δ10 desaturation pathway in Camelina sativa to produce yellow peach moth pheromone precursors, achieving up to 4.7% target fatty acids in seeds.

Paving the way for plant-based bioproduction of (Z)-13-octadecenoic moth pheromone compounds

This paper demonstrates the biotechnological production of C18 pheromone precursors in Camelina sativa using insect enzymes, enabling sustainable pest control.

Female-biased expressed odorant receptor genes differentially tuned to repulsive or attractive plant volatile compounds in the turnip moths

The paper identifies female-biased odorant receptor genes in turnip moths that respond to plant volatile compounds, showing some are attractive and others repulsive.

Odorant receptor orthologues in conifer-feeding beetles display conserved responses to ecologically relevant odors

This study functionally characterizes odorant receptor orthologues in three conifer-feeding beetle species, finding conserved responses to ecologically relevant odors.

A highly contiguous genome assembly of a major forest pest, the Eurasian spruce bark beetle Ips typographus

The paper presents a high-quality genome assembly of the Eurasian spruce bark beetle, revealing gene families related to plant cell wall degradation and providing resources for studying its evolutionary biology and pest control.

Functional evolution of a bark beetle odorant receptor clade detecting monoterpenoids of different ecological origins

The paper functionally characterizes odorant receptors in bark beetles, revealing their specific responses to monoterpenoids from different ecological sources and suggesting neofunctionalization after gene duplication.

Putative ligand binding sites of two functionally characterized bark beetle odorant receptors

The paper identifies and characterizes two odorant receptors in bark beetles, predicting their ligand binding sites and highlighting key residues involved in pheromone recognition.

Mate discrimination among subspecies through a conserved olfactory pathway

The paper identifies two male-specific pheromones in Drosophila mojavensis subspecies and shows how they contribute to sexual isolation through conserved sensory pathways and differential interpretation.
