The paper investigates the genetic basis of floral scent divergence in Gongora orchids, identifying candidate genes and pathways involved in the transition from monoterpene to phenylpropanoid emission.

The paper analyzes floral evolution in orchids to show that specialized pollination by scent-collecting bees leads to faster floral shape evolution than other pollination strategies.

This study identifies odorant receptors in Drosophila that detect toxic mustard oils, showing that herbivorous relatives have expanded and adapted these receptors for hostplant recognition.

This study identifies a regulatory change in the fatty acid elongase eloF as the genetic basis for sex-specific pheromone profile evolution in Drosophila prolongata.

This study shows that hummingbird-pollinated Costus species lose floral scent through gene downregulation, not pseudogenization, highlighting strong selection pressures for scent loss.

This study analyzes P450 gene evolution in ten bee species, finding that detoxification-related genes are in unstable clades under adaptive pressures, but no link between resin collection and P450 repertoire was found.

The paper reports the nuclear and mitochondrial genome sequences of the orchid bee Euglossa dilemma, providing a high-quality assembly and gene set, and highlighting gene synteny conservation with honey bees.
