Transcriptomic analysis of deceptively pollinated Arum maculatum (Araceae) reveals association between terpene synthase expression in floral trap chamber and species-specific pollinator attraction
<p>A compressed folder containing the R script and input files required to replicate the results in our manuscript entitled "Transcriptomic analysis of deceptively pollinated <em>Arum maculatum</em> (Araceae) reveals association between terpene synthase expression in floral trap chamber and species-specific pollinator attraction".</p> <p>Note: Raw Illumina sequencing files associated with this study have been uploaded to NCBI SRA, under the BioProject accession PRJNA856436.</p> <p><strong>ABSTRACT</strong></p> <p>Deceptive pollination often involves volatile organic compound (VOC) emissions that mislead insects into performing non-rewarding pollination. Among deceptively pollinated plants, <em>Arum maculatum</em> is particularly well-known for its potent dung-like VOC emissions and specialized floral chamber, which traps pollinators – mainly <em>Psychoda phalaenoides</em>and <em>P. grisescens</em> – overnight. However, little is known about the genes underlying the production of many <em>A. maculatum</em>VOCs, and their influence on variation in pollinator attraction rates. Therefore, we performed <em>de novo</em> transcriptome sequencing of <em>A. maculatum</em> appendix and male floret tissue collected during- and post-anthesis, from ten natural populations across Europe. These RNA-seq data were paired with GC-MS analyses of floral scent composition and pollinator data collected from the same inflorescences. Differential expression analyses revealed candidate transcripts in appendix tissue linked to malodourous VOCs including indole, <em>p</em>-cresol, and 2-heptanone. Additionally, we found that terpene synthase expression in male floret tissue during anthesis significantly covaried with sex- and species-specific attraction of <em>Psychoda phalaenoides</em> and <em>P.</em> <em>grisescens</em>. Taken together, our results provide the first insights into molecular mechanisms underlying pollinator attraction patterns in <em>A. maculatum</em>, and highlight floral chamber sesquiterpene (<em>e.g.</em>bicyclogermacrene) synthases as interesting candidate genes for further study.</p>
