“…Collectively, the data document a diverse SNMP gene family with variable numbers of SNMPs in species of the same and different insect orders ranging from two SNMPs in the vinegar fly Drosophila melanogaster (Nichols and Vogt 2008) to 16 in the dung beetle Onthophagus taurus (Zhao et al 2020). Within a species, paralogues of the same SNMP type may exist; for example, the genome of the hessian fly Mayetiola destructor encodes six SNMP1 paralogues, five of which are transcribed in the antennae (Andersson et al 2014).…”

“…Following the discovery of SNMPs in moths, orthologues have been identified in many insect species from various orders, utilizing available SNMP sequences in extensive homology-based searches of transcriptome and genome databases (Vogt et al 2009, Zhao et al 2020. Within a given species, several SNMP-types have been revealed, which appeared to be differentially expressed in distinct subpopulations of the OR-expressing OSNs (Rogers et al 2001a, Benton et al 2007, Pregitzer et al 2019 and (contrary to what the name SNMP implies) in the support cells of olfactory sensilla (Forstner et al 2008, Gu et al 2013, Blankenburg et al 2019.…”

“…The rapid progress in sequencing technologies and bioinformatics tools has significantly promoted the identification of new SNMPs within and beyond Lepidoptera (Table S1). Over the last decades, BLAST analyses of genomes and transcriptomes employing available SNMPs identified candidate SNMPs in various insects of holometabolous orders, namely, Diptera (flies and mosquitoes), Coleoptera (beetles), Hymenoptera (bees and wasps), and Neoptera (lacewings), as well as hemimetabolous insects, i.e., Hemiptera (bugs), Orthoptera (locusts), and Psocodea (lice) (overview in Nichols and Vogt 2008, Jiang et al 2016, Zhao et al 2020.…”

“…Within a species, paralogues of the same SNMP type may exist; for example, the genome of the hessian fly Mayetiola destructor encodes six SNMP1 paralogues, five of which are transcribed in the antennae (Andersson et al 2014). Similarly, the red flour beetle Tribolium castaneum comprises paralogous genes for four SNMP1s, three SNMP2s, and two SNMP3s (Zhao et al 2020). Paralogous genes encoding SNMP1s, SNMP2s, and SNMP3s appear to be typical for beetles as impressively demonstrated by a recent study that annotated and characterized 128 SNMPs from the genomes and transcriptomes of 22 coleopteran species.…”

The sense of smell enables insects to recognize olfactory signals crucial for survival and reproduction. In insects, odorant detection highly depends on the interplay of distinct proteins expressed by specialized olfactory sensory neurons (OSNs) and associated support cells which are housed together in chemosensory units, named sensilla, mainly located on the antenna. Besides odorant-binding proteins (OBPs) and olfactory receptors, so-called sensory neuron membrane proteins (SNMPs) are indicated to play a critical role in the detection of certain odorants. SNMPs are insect-specific membrane proteins initially identified in pheromone-sensitive OSNs of Lepidoptera and are indispensable for a proper detection of pheromones. In the last decades, genome and transcriptome analyses have revealed a wide distribution of SNMP-encoding genes in holometabolous and hemimetabolous insects, with a given species expressing multiple subtypes in distinct cells of the olfactory system. Besides SNMPs having a neuronal expression in subpopulations of OSNs, certain SNMP types were found expressed in OSN-associated support cells suggesting different decisive roles of SNMPs in the peripheral olfactory system. In this review, we will report the state of knowledge of neuronal and non-neuronal members of the SNMP family and discuss their possible functions in insect olfaction.

“…SNMPs, a homologue of the CD36 protein family, are signaling components crucial for odorant sensitivity [21]. The SNMP family is small, and usually have 2-3 subgroups in Diptera, Lepidoptera and other insect orders [22]. SNMP1 orthologs are mainly expressed in pheromone-sensitive ORNs, and participate in the perception of sex pheromones [21].…”

Olfaction plays vital roles in the survival and reproduction of insects. The completion of olfactory recognition requires the participation of various complex protein families. However, little is known about the olfactory-related proteins in Semiothisa cinerearia Bremer et Grey, an important pest of Chinese scholar tree. In this study, we sequenced the antennal transcriptome of S. cinerearia and identified 125 olfactory-related genes, including 25 odorant-binding proteins (OBPs), 15 chemosensory proteins (CSPs), two sensory neuron membrane proteins (SNMPs), 52 odorant receptors (ORs), eight gustatory receptors (GRs) and 23 ionotropic receptors (IRs). BLASTX best hit results and phylogenetic analyses indicated that these genes were most identical to their respective orthologs from Ectropis obliqua. Further quantitative real-time PCR (qRT-PCR) analysis revealed that three ScinOBPs and three ScinORs were highly expressed in male antennae, while seven ScinOBPs and twelve Sci-nORs were female-specifically expressed. Our study will be useful for the elucidation of olfactory mechanisms in S. cinerearia.

Longhorned beetles (Cerambycidae) are a diverse family of wood-boring insects, many species of which produce volatile pheromones to attract mates over long distances. The composition and structure of the pheromones remain constant across many cerambycid species, and comparative studies of those groups could therefore reveal the chemoreceptors responsible for pheromone detection. Here, we use comparative transcriptomics to identify a candidate pheromone receptor in the large and economically important cerambycid genus Monochamus, males of which produce the aggregation-sex pheromone 2-(undecyloxy)-ethanol ("monochamol"). Antennal transcriptomes of the North American species M. maculosus, M. notatus, and M. scutellatus revealed 60-70 odorant receptors (ORs) in each species, including four lineages of simple orthologs that were highly conserved, highly expressed in both sexes, and upregulated in the flagellomeres where olfactory sensilla are localized. Two of these orthologous lineages, OR29 and OR59, remained highly expressed and conserved when we included a re-annotation of an antennal transcriptome of the Eurasian congener M. alternatus. OR29 is also orthologous to a characterized pheromone receptor in the cerambycid Megacyllene caryae, suggesting it as the most likely candidate for a monochamol receptor and highlighting its potential as a conserved lineage of pheromone receptors within one of the largest families of beetles.
