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>
Data from: Floral scents of a deceptive plant are hyperdiverse and under population-specific phenotypic selection
<p>Floral scent is a key mediator in plant–pollinator interactions; however, little is known to what extent intraspecific scent variation is shaped by phenotypic selection, with no information yet in deceptive plants. We recorded 289 scent compounds in deceptive moth fly-pollinated <i>Arum maculatum </i>from various populations north vs. south of the Alps, the highest number so far reported in a single plant species. Scent and fruit set differed between regions, and some, but not all differences in scent could be explained by differential phenotypic selection in northern vs. southern populations. Our study is the first to provide evidence that phenotypic selection is involved in shaping geographic patterns of floral scent in deceptive plants. The hyperdiverse scent of <i>A. maculatum</i> might result from the plant's imitation of various brood substrates of its pollinators.</p>

Data from: Appearances can be deceptive: bizarre shell microanatomy and histology in a new Triassic turtle (Testudinata) from Argentina at the dawn of turtles
The origin and homology of the turtle shell are one of the most captivating topics in amniote evolution. In this contribution, we present a new species of turtle from the Late Triassic of Argentina whose peripheral plates question the homology of these bones in turtles. The external morphology of the peripheral plates of <i></i>Waluchelys cavitesta<i></i> gen. et sp. nov. (Testudinata: Australochelyidae) is as in any other turtle, however, appearances can be deceiving. Internally, these plates exhibit an unexpected internal cavity. The absence of structural similarities and of ontogenetic or phylogenetic transitional forms between the peripheral plates of W. cavitesta and other testudinatans might suggest that the periphery of turtles represents a case of deep homology. Furthermore, the present and recent findings suggest that the structure and ossification patterns of the periphery of the turtle shell were more plastic and subject to variation than other elements of the shell, at least in the earliest stages of turtle evolution. These findings also suggest that the "typical" mesochelydian turtle shell could have been acquired in a two-stage process.

Subtle ecophysiological divergences in a deceptive strategy to attract pollinators in two sympatric Arum
<p>Most Angiosperms rely on insect pollinators for their reproduction, implying the evolution of attractive signals. While most plants reward their pollinators, others use a deceptive method where no direct benefit is offered to pollinators. Integrative approaches are mandatory to comprehend the evolution of deceptive strategies, by combining the co-variations in different floral traits and the behavior of the insects. However, they were rarely applied to compare species competing for the same pollinators. We applied an ecophysiological approach to compare floral traits – scent and thermogenesis – in two deceptive sympatric arums (<em>Arum maculatum</em> and <em>Arum italicum</em>) that are pollinated mainly by<em> Psychoda</em> moth flies. We tested the hypothesis that floral traits diverged between the two arums to minimize their interference as they attract locally the same insects. We measured the thermogenesis sequence of both species in their natural environment and volatile organic compounds were analyzed. As expected, the two arums displayed a similar thermogenesis sequence. However, the main thermogenesis peak, which is actively involved in pollinator attraction was warmer in <em>A. italicum </em>and it happened earlier during the day for <em>A. maculatum</em>. For scents, we confirmed a strong differentiation between the two arums when they co-occur. Then, we determined the effect of the different scents on the activity level of their main moth fly pollinator (<em>Psychoda sigma</em>) at our study site to reveal that the odor of <em>A. maculatum</em> tended to stimulate the insect activity more than the odor of <em>A. italicum</em>. This moth fly is nocturnal and therefore <em>A. maculatum</em>, which flowers right before nighttime may need to overstimulate the insect activity to get visited. Our integrative approach highlights that the two sympatric arums have slightly shifted daily phenologies, which implied a fine-tune variation in the attractive volatiles and the thermogenesis sequence in relation to the behavior of the pollinating moth fly. Our results suggest that a tradeoff may exist between odor specificity and the ability to maximize volatile emission. These findings show how evolutionarily close species living in sympatry can diverge finely to lower competing interference and attract the same pollinators.</p>

Data from: The functional significance of complex floral colour pattern in a food-deceptive orchid
Many non-rewarding orchid species mimic the signals of co-occurring food flowers and thereby attract food-seeking animal pollinators. These signals are often visually complex with a colour pattern that contrasts between outer and central parts. The significance of this colour complexity for the pollination success of flowers of deceptive orchids has scarcely been investigated. We tested the effects of the colour patterns of the food-deceptive orchid Paphiopedilum micranthum on bumblebee visitation choices and pollination success using behavioural experiments in a community context. Using comparative phylogenetic analysis and a bee vision model, we also compared the colour patterns of P. micranthum with those of its congeners and sympatric food flowers. The probability of both long-range approach and close-up choice by bumblebees to orchids was all enhanced in communities with food flowers similar in colour pattern to the orchid. Probability of long-range approach and close-up choice was negatively correlated with colour distance between orchid and food flowers in floral outer and centre, respectively. Flowers of P. micranthum that were manipulated to reduce visual complexity had reduced male and female pollination success. Phylogenetic analysis revealed that the outer floral colour of P. micranthum is apomorphic and thus likely represents an evolutionary innovation, whereas the central colour is plesiomorphic and thus likely to function in the bumblebee pollination system as an exaptation. The contrast between the inner and outer colours appears to exploit visual preferences of bumblebees acquired during foraging on local food plants with similar colour patterns. This study highlights the adaptive significance of colour patterns in successful food deception and the importance of complex signals in facilitating interspecific interactions.
Data from: Costs of deception and learned resistance in deceptive interactions
The costs that species suffer when deceived are expected to drive learned resistance, although this relationship has seldom been studied experimentally. Flowers that elicit mating behaviour from male insects by mimicking conspecific females provide an ideal system for such investigation. Here, we explore interactions between a sexually deceptive daisy with multiple floral forms that vary in deceptiveness, and the male flies that pollinate it. We show that male pollinators are negatively impacted by the interaction, suffering potential mating costs in terms of their ability and time taken to locate genuine females within deceptive inflorescences. The severity of these costs is determined by the amount of mating behaviour elicited by deceptive inflorescences. However, inexperienced male flies exhibit the ability to learn to discriminate the most deceptive inflorescences as female mimics and subsequently reduce the amount of mating behaviour they exhibit on them with increased exposure. Experienced males, which interact with sexually deceptive forms naturally, exhibit similar patterns of reduced mating behaviour on deceptive inflorescences in multiple populations, indicating that pollinator learning is widespread. As sexually deceptive plants are typically dependent on the elicitation of mating behaviour from male pollinators for pollination, this may result in antagonistic coevolution within these systems.
