Data from: Conserved but attenuated parental gene expression in allopolyploids: constitutive zinc hyperaccumulation in the allotetraploid Arabidopsis kamchatica

Timothy Paape, Masaomi Hatakeyama, Rie Shimizu-Inatsugi, Teo Cereghetti, Onda Yoshihiko, Tanaka Kenta, Jun Sese & Kentaro K. Shimizu
Allopolyploidization combines parental genomes and often confers broader species distribution. However, little is known about parentally transmitted gene expression underlying quantitative traits following allopolyploidization because of the complexity of polyploid genomes. The allopolyploid species Arabidopsis kamchatica is a natural hybrid of the zinc hyperaccumulator A. halleri and of the nonaccumulator A. lyrata. We found that A. kamchatica retained the ability to hyperaccumulate zinc from A. halleri and grows in soils with both low and high...

Data from: Importance of antecedent environmental conditions in modeling species distributions

Masahiro Ryo, Chihiro Yoshimura & Yuichi Iwasaki
Although species distributions can change in an unexpectedly short period of time, most species distribution models (SDMs) use only long-term averaged environmental conditions to explain species distributions. We aimed to demonstrate the importance of incorporating antecedent environmental conditions into SDMs in comparison to long-term averaged environmental conditions. We modeled the presence/absence of 18 fish species captured across 108 sampling events along a 50-km length of the Sagami River in Japan throughout the 1990s (one to...

Automatic radioisotope manipulation for small amount of nuclear medicine using an EWOD device with a dimple structure

Katsuo Mogi, Hiroyuki Kimura, Yuto Kondo, Tomoya Inoue, Shungo Adachi & Tohru Natsume
Delicate animal experiments and microdose clinical trials using short-lived radioisotopes require rapid preparation with high accuracy and careful attention to safety within a limited timeframe. We have developed an open-style electrowetting on dielectric device containing dimple structures for the rapid preparation of radiolabelled reagents. The device was demonstrated by automatic preparation of a 99mTc-DTPA with high chelation efficiency (99.7 ± 0.13%). Additionally, we demonstrated the single photon emission computed tomography (SPECT)/Computed tomography (CT) imaging of...

Phosphate bound to calcareous sediments hamper skeletal development of juvenile coral

Mariko Iijima
To test the hypothesis that terrestrial runoff affects the functions of calcareous sediments in coral reefs and hampers the development of corals, we analysed calcareous sediments with different levels of bound phosphate, collected from reef areas of Okinawajima, Japan. We confirmed that phosphate bound to calcareous sediments were readily released into ambient seawater, resulting in much higher concentrations of phosphorous in seawater from heavily polluted areas (4.3 to 19.0 µM as compared with < 0.096...

Comprehensive comparative morphology and developmental staging of final instar larvae toward metamorphosis in the insect order Odonata

Genta Okude, Takema Fukatsu & Ryo Futahashi
The order Odonata (dragonflies and damselflies) is among the most ancestral groups of winged insects with drastic morphological changes upon metamorphosis, and thus important for understanding evo-devo aspects of insects. However, basic developmental descriptions of Odonata have been scarce. In an attempt to establish the foundation of developmental and experimental biology of Odonata, we present an unprecedentedly comprehensive survey of dragonflies and damselflies, in total 158 larvae representing 49 species and 14 families, wherein morphological...

Data from: Single mutation makes Escherichia coli an insect mutualist

Ryuichi Koga
We report an experimental system in which Escherichia coli evolves into an insect mutualist. When the essential gut symbiont of the stinkbug Plautia stali was replaced by E. coli, a few survivor insects exhibited specific localization and vertical transmission of E. coli. Through trans-generational maintenance with P. stali, several hyper-mutating E. coli lines independently evolved host’s high adult emergence and improved body color. Such “mutualistic” E. coli lines exhibited independent mutations disrupting the carbon catabolite...

Data from: Live imaging of symbiosis: spatiotemporal infection dynamics of GFP-labelled Burkholderia symbiont in the bean bug Riptortus pedestris

Yoshitomo Kikuchi & Takema Fukatsu
Many insects possess endosymbiotic bacteria inside their body, wherein intimate interactions occur between the partners. While recent technological advancements have deepened our understanding of metabolic and evolutionary features of the symbiont genomes, molecular mechanisms underpinning the intimate interactions remain difficult to approach because the insect symbionts are generally uncultivable. The bean bug Riptortus pedestris is associated with the betaproteobacterial Burkholderia symbiont in a posterior region of the midgut, which develops numerous crypts harbouring the symbiont...

Data from: Prediction error induced motor contagions in human behaviors

Tsuyoshi Ikegami, Gowrishankar Ganesh, Tatsuya Takeuchi & Hiroki Nakamoto
Motor contagions refer to implicit effects on one's actions induced by observed actions. Motor contagions are believed to be induced simply by action observation and cause an observer's action to become similar to the action observed. In contrast, here we report a new motor contagion that is induced only when the observation is accompanied by prediction errors - differences between actions one observes and those he/she predicts or expects. In two experiments, one on whole-body...

Data from: Functional crosstalk across IMD and Toll pathways: insight into the evolution of incomplete immune cascades

Yudai Nishide, Daisuke Kageyama, Kakeru Yokoi, Akiya Jouraku, Hiromitsu Tanaka, Ryo Futahashi & Takema Fukatsu
In insects, antimicrobial humoral immunity is governed by two distinct gene cascades, IMD pathway mainly targeting Gram-negative bacteria and Toll pathway preferentially targeting Gram-positive bacteria, which are widely conserved among diverse metazoans. However, recent genomic studies uncovered that IMD pathway is exceptionally absent in some hemipteran lineages like aphids and assassin bugs. How the apparently incomplete immune pathways have evolved with functionality is of interest. Here we report the discovery that, in the hemipteran stinkbug...

Data from: Evolution of a key trait greatly affects underground community assembly process through habitat adaptation in earthworms

Hiroshi Ikeda, Kayoko Fukumori, Etsuko Shoda-Kagaya, Masamichi Takahashi, Masamichi Ito, Yoshimi Sakai, Kazuma Matsumoto & Masamichi T. Ito
Underground community assemblies have not been studied well compared with aboveground communities, despite their importance for our understanding of whole ecosystems. To investigate underground community assembly over evolutionary time scales, we examined terrestrial earthworm communities (Oligochaeta: Haplotaxida) in conserved mountainous primary forests in Japan as a model system. We collected 553 earthworms mostly from two dominant families, the Megascolecidae and the Lumbricidae, from 12 sites. We constructed a molecular taxonomic unit tree based on the...

Data from: Patterns of polymorphism and selection in the subgenomes of the allopolyploid Arabidopsis kamchatica

Timothy Paape, Roman V. Briskine, Gwyneth Halstead-Nussloch, Heidi E. L. Lischer, Rie Shimizu-Inatsugi, Masaomi Hatekayama, Kenta Tanaka, Tomoaki Nishiyama, Renat Sabirov, Jun Sese & Kentaro K. Shimizu
Genome duplication is widespread in wild and crop plants. However, little is known about genome-wide selection in polyploids due to the complexity of duplicated genomes. In polyploids, the patterns of purifying selection and adaptive substitutions may be affected by masking owing to duplicated genes or homeologs as well as effective population size. Here, we resequence 25 accessions of the allotetraploid Arabidopsis kamchatica, which is derived from the diploid species A. halleri and A. lyrata. We...

Data from: Evolution of music by public choice

Robert M. MacCallum, Matthias Mauch, Austin Burt & Armand M. Leroi
Music evolves as composers, performers, and consumers favor some musical variants over others. To investigate the role of consumer selection, we constructed a Darwinian music engine consisting of a population of short audio loops that sexually reproduce and mutate. This population evolved for 2,513 generations under the selective influence of 6,931 consumers who rated the loops’ aesthetic qualities. We found that the loops quickly evolved into music attributable, in part, to the evolution of aesthetically...

Data from: Forward modeling the rubber hand: illusion of ownership modifies motor-sensory predictions by the brain

Laura Aymerich-Franch, Damien Petit, Gowrishankar Ganesh & Abderrahmane Kheddar
The question of how we attribute observed body parts as our own, and the consequences of this attribution on our sensory-motor processes, is fundamental to understand how our brain distinguishes between self and other. Previous studies have identified interactions between the illusion of ownership, and multi-sensory integration and cross-sensory predictions by the brain. Here we show that illusory ownership additionally modifies the motor-sensory predictions by the brain. In our preliminary experiments, we observed a new...

Data from: Water-repellent plant surface structure induced by gall-forming insects for waste management

Keigo Uematsu, Mayako Kutsukake & Takema Fukatsu
Many animals and plants have evolved elaborate water-repellent microstructures on their surface, which often play important roles in their ecological adaptation. Here we report a unique type of water-repellent structure on plant surface, which develops as an insect-induced plant morphology in a social context. Some social aphids form galls on their host plant, in which they produce large amount of hydrophobic wax. Excreted honeydew is coated by the powdery wax to form “honeydew balls”, which...
