Special Issue Information
Dear Colleagues,
Olfaction and taste are the two main chemosensory systems of vertebrates and arthropods. In vertebrates, four olfactory and two taste receptor families (OR, TAAR, V1R, V2R, T1R, T2R) mediate the detection of odorants and tastants, whereas in insects, three unrelated receptor families (OR, IR, GR) perform these tasks. A hallmark of these families is dynamic evolution, characterized by many gene birth and death events. This is assumed to be according to the ecological needs of the respective species, but our understanding of such adaptations is incomplete. In particular, functional studies addressing these receptors remain very limited. Recent advances in high-throughput sequencing have enabled the characterization of chemosensory families in ever more species, and thus their adaptation to a wide variety of ecological contexts has come to the fore. Moreover, the manifold regulation of expression (developmental age, exposure, internal states) results in dynamic receptor repertoires, even within a species and organism.
For this Special Issue, we invite original research articles that showcase the evolution, function or regulation of olfactory or gustatory receptors (vertebrates and insects, as well as studies on other invertebrates). Critical reviews of recent advances in the field are also welcome.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
