Thermogenesis‐derived spatiotemporal microclimates guide pollinator movement to ensure pollination

Journal of Integrative Plant Biology, EarlyView.
Alocasia odora's microclimatic heterogeneity guides Colocasiomyia fly movement within its inflorescence. During the female stage, midday heat in the upper spadix pushes flies down to the cooler female zone. During the male stage, nocturnal warmth in the upper part pulls flies upward and spathe constriction closes the lower female chamber.

Shifts in type 2 vomeronasal receptor expression during postnatal development in the lungfish olfactory organ

Journal of Anatomy, EarlyView.
Lungfish possess a lamellar OE and a primitive VNO called as a recess epithelium (RecE). Among the lungfish V2Rs expressed in both the lamellar OE and the RecE in small individuals, some became restricted to the RecE in large individuals. These results suggest functional separation between the lamellar OE and the RecE is still incomplete in juveniles ...

Comparative transcriptomics and phylostratigraphy of Argentine ant odorant receptors.

PLoS ONE
Nestmate recognition in ants is regulated through the detection of cuticular hydrocarbons by odorant receptors (ORs) in the antennae. These ORs are crucial for maintaining colony cohesion that allows invasive ant species to dominate colonized ...

Functional evolution of mammalian odorant receptors.

PLoS Genetics, 2012
The mammalian odorant receptor (OR) repertoire is an attractive model to study evolution, because ORs have been subjected to rapid evolution between species, presumably caused by changes of the olfactory system to adapt to the environment.

GLP‐1 Receptor Agonists and Weight Loss: A Critical Review of Mechanisms

Obesity Reviews, EarlyView.
ABSTRACT GLP‐1 receptor agonist medications have the potential to promote marked weight loss, but maximal and sustained benefit may be compromised by poor compliance and cessation of use. Development of next‐generation medications that address current obstacles to effective use and development of effective adjunct treatments will benefit from better ...

Evaluation of the DREAM Technique for a High-Throughput Deorphanization of Chemosensory Receptors in Drosophila

Frontiers in Molecular Neuroscience, 2018
In the vinegar fly Drosophila melanogaster, the majority of olfactory receptors mediating the detection of volatile chemicals found in their natural habitat have been functionally characterized (deorphanized) in vivo. In this process, receptors have been

Antennal and abdominal transcriptomes reveal chemosensory gene families in the coconut hispine beetle, Brontispa longissima

Scientific Reports, 2017
Antennal and abdominal transcriptomes of males and females of the coconut hispine beetle Brontispa longissima were sequenced to identify and compare the expression patterns of genes involved in odorant reception and detection.

Selectivity of Odorant Receptors in Insects

Frontiers in Cellular Neuroscience, 2012
Insect olfactory receptors (ORs) detect chemicals, shape neuronal physiology and regulate behavior.  Although ORs have been categorized as generalists and specialists based on their ligand spectrum, both electrophysiological studies and recent ...

From Odors to Colors: Sensory Perception in Neurodiverse Mexican Youth

Topics in Cognitive Science, EarlyView.
Abstract Previous work has shown that humans make consistent associations between odor and color. However, neurodiverse individuals, especially those with autism spectrum disorder (ASD), perceive and interpret sensory information differently from their neurotypical peers.

Testing odorant-receptor interaction theories in humans through discrimination of isotopomers

Journal of Biological Research, 2017
Odour reception takes place on the olfactory receptor neuron membrane, where molecular receptors interact with volatile odorant molecules. This interaction is classically thought to rely on chemical and structural features of the odorant, e.g.
