Whole-genome identification of chemosensory genes in two sister blister beetles provides insights into chemosensory evolution [PDF]

open access: yes, 2019
Abstract Background: Commonly known as blister beetles or Spanish fly, there are more than 1,500 species in the Meloidae family (Coleoptera:Tenebrionoidea) that produce the potent defensive blistering agent cantharidin, which has recently been exploited for cancer therapy.

Automated Profiling of Social Behaviors to Assess the Genetic Basis of Evolution of Aggressive Behaviors in Astyanax mexicanus

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Across the animal kingdom, social behaviors such as aggression are critical for survival and reproductive success. While there is significant variation in social behaviors within and between species, the genetic mechanisms underlying natural variation in social behaviors are poorly understood.

The sea lamprey genome reveals the early origin of several chemosensory receptor families in the vertebrate lineage [PDF]

open access: yes, 2009
Background In gnathostomes, chemosensory receptors (CR) expressed in olfactory epithelia are encoded by evolutionarily dynamic gene families encoding odorant receptors (OR), trace amine-associated receptors (TAAR), V1Rs and V2Rs.

Antennal transcriptome analysis of the chemosensory gene families in Carposina sasakii (Lepidoptera: Carposinidae)

open access: yesBMC Genomics, 2018
Background The peach fruit moth, Carposina sasakii Matsumura (Lepidoptera: Carposinidae), poses a serious threat to a variety of fruits and causes significant economic loss owing to difficulties in its prevention and control.

Can trigeminal sensations impact saltiness perception? A mini‐review

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract Many food companies have begun to reduce the salt content in their products due to health concerns; however, this reduction in salt content can affect the food's sensory appeal and flavour complexity. Flavour is defined as a combination of odour (i.e., smell), taste (i.e., gustation) and trigeminal sensations (i.e., chemesthesis).

Family Size Evolution in Drosophila Chemosensory Gene Families: A Comparative Analysis with a Critical Appraisal of Methods [PDF]

open access: yes, 2014
Gene turnover rates and the evolution of gene family sizes are important aspects of genome evolution. Here, we use curated sequence data of the major chemosensory gene families from Drosophila-the gustatory receptor, odorant receptor, ionotropic receptor,

Evolutionary dynamics of olfactory and other chemosensory receptor genes in vertebrates [PDF]

open access: yesJournal of Human Genetics, 2006
The numbers of functional olfactory receptor (OR) genes in humans and mice are about 400 and 1,000 respectively. In both humans and mice, these genes exist as genomic clusters and are scattered over almost all chromosomes. The difference in the number of genes between the two species is apparently caused by massive inactivation of OR genes in the human

Adaptation of the invasive pest Drosophila suzukii to a specialized nutritional niche

open access: yesInsect Science, EarlyView.
Unlike most Drosophila larvae that feed on spoiled food, Drosophila suzukii larvae thrive on ripening fruits and consequently face a low‐protein, high‐carbohydrate nutritional challenge. Comparisons of growth among D. suzukii, D. biarmipes, and D. melanogaster larvae across diets with varying protein‐to‐carbohydrate ratios demonstrate that D.

Extensive local adaptation within the chemosensory system following Drosophila melanogaster's global expansion. [PDF]

open access: yes, 2016
How organisms adapt to new environments is of fundamental biological interest, but poorly understood at the genetic level. Chemosensory systems provide attractive models to address this problem, because they lie between external environmental signals and

Sniffing Out Chemosensory Genes from the Mediterranean Fruit Fly, Ceratitis capitata

open access: yesPLoS ONE, 2014
The Mediterranean fruit fly, Ceratitis capitata (medfly), is an extremely invasive agricultural pest due to its extremely wide host range and its ability to adapt to a broad range of climatic conditions and habitats. Chemosensory behaviour plays an important role in many crucial stages in the life of this insect, such as the detection of pheromone cues
