Data from: Phytochrome diversity in green plants and the origin of canonical plant phytochromes

Phytochromes are red/far-red photoreceptors that play essential roles in diverse plant morphogenetic and physiological responses to light. Despite their functional significance, phytochrome diversity and evolution across photosynthetic eukaryotes remain poorly understood. Using newly available transcriptomic and genomic data we show that canonical plant phytochromes originated in a common ancestor of streptophytes (charophyte algae and land plants). Phytochromes in charophyte algae are structurally diverse, including canonical and non-canonical forms, whereas in land plants, phytochrome structure is...

Data from: Bacterial diversity amplifies nutrient-based plant-soil feedbacks

Simone Weidner, Robert Koller, Ellen Latz, George Kowalchuk, Michael Bonkowski, Stefan Scheu & Alexandre Jousset
Plants foster diverse assemblages of bacteria in the rhizosphere serving important functions which may result in enhanced plant growth. Microbial diversity is increasingly recognized to shape the functionality of microbial communities. This leads to the assumption that there is a positive relationship between rhizosphere diversity and plant growth. Here we investigate how bacterial diversity affects the mineralization of organic matter and plant nutrient acquisition. We hypothesized that altered bacterial diversity will affect nitrogen mineralisation, uptake...

Data from: Stronger neural modulation by visual motion intensity in autism spectrum disorders

Ina Peiker, Till R. Schneider, Elizabeth Milne, Daniel Schöttle, Kai Vogeley, Alexander Münchau, Odette Schunke, Markus Siegel, Andreas K. Engel & Nicole David
Theories of autism spectrum disorders (ASD) have focused on altered perceptual integration of sensory features as a possible core deficit. Yet, there is little understanding of the neuronal processing of elementary sensory features in ASD. For typically developed individuals, we previously established a direct link between frequency-specific neural activity and the intensity of a specific sensory feature: Gamma-band activity in the visual cortex increased approximately linearly with the strength of visual motion. Using magnetoencephalography (MEG),...

Data from: Ethnicity- and sex-based discrimination and the maintenance of self-esteem

Jan-Erik Lönnqvist, Heike Hennig-Schmidt & Gari Walkowitz
The psychological underpinnings of labor market discrimination were investigated by having participants from Israel, the West Bank and Germany (N = 205) act as employers in a stylized employment task in which they ranked, set wages, and imposed a minimum effort level on applicants. State self-esteem was measured before and after the employment task, in which applicant ethnicity and sex were salient. The applicants were real people and all behavior was monetarily incentivized. Supporting the...

Data from: The origin and evolution of phototropins

Fay-Wei Li, Kathleen M. Pryer, Gane K.-S. Wong, Carl J. Rothfels, Michael Melkonian, Sarah Mathews, Juan C. Villarreal & Sean W. Graham
Plant phototropism, the ability to bend toward or away from light, is predominantly controlled by blue-light photoreceptors, the phototropins. Although phototropins have been well-characterized in Arabidopsis thaliana, their evolutionary history is largely unknown. In this study, we complete an in-depth survey of phototropin homologs across land plants and algae using newly available transcriptomic and genomic data. We show that phototropins originated in an ancestor of Viridiplantae (land plants + green algae). Phototropins repeatedly underwent independent...

Data from: Not all are free-living: high-throughput DNA metabarcoding reveals a diverse community of protists parasitizing soil metazoa

Stefan Geisen, Ivo Laros, Antón Vizcaíno, Michael Bonkowski & G. Arjen De Groot
Protists, the most diverse eukaryotes, are largely considered to be free-living bacterivores, but vast numbers of taxa are known to parasitize plants or animals. High-throughput sequencing (HTS) approaches now commonly replace cultivation-based approaches in studying soil protists, but insights into common biases associated with this method are limited to aquatic taxa and samples. We created a mock community of common free-living soil protists (amoebae, flagellates, ciliates), extracted DNA and amplified it in the presence of...
