Data from: Post-Turing tissue pattern formation: advent of mechanochemistry

Felix Brinkmann, Moritz Mercker, Thomas Richter & Anna Marciniak-Czochra
Chemical and mechanical pattern formation is fundamental during embryogenesis and tissue development. Yet, the underlying molecular and cellular mechanisms are still elusive in many cases. Most current theories assume that tissue development is driven by chemical processes: either as a sequence of chemical patterns each depending on the previous one, or by patterns spontaneously arising from specific chemical interactions (such as “Turing-patterns”). Within both theories, mechanical patterns are usually regarded as passive by-products of chemical...

Data from: Non-rhythmic head-direction cells in the parahippocampal region are not constrained by attractor network dynamics

Olga Kornienko, Patrick Latuske, Mathis Bassler, Laura Kohler & Kevin Allen
Computational models postulate that HD cells are part of an attractor network integrating angular head turns. This network requires inputs from visual landmarks to anchor the HD signal to the external world. We investigated whether information about HD and visual landmarks is integrated in the medial entorhinal cortex and parasubiculum, resulting in neurons expressing a conjunctive code for HD and visual landmarks. We found that parahippocampal HD cells could be divided into two classes based...

Data from: Wnt/PCP controls spreading of Wnt/β-catenin signals by cytonemes in vertebrates

Signaling filopodia, termed cytonemes, are dynamic actin-based membrane structures that regulate the exchange of signaling molecules and their receptors within tissues. However, how cytoneme formation is regulated remains unclear. Here, we show that Wnt/PCP autocrine signaling controls the emergence of cytonemes, and that cytonemes subsequently control paracrine Wnt/β-catenin signal activation. Upon binding of the Wnt family member Wnt8a, the receptor tyrosine kinase Ror2 gets activated. Ror2/PCP signaling leads to induction of cytonemes, which mediate transport...

Data from: Brassicales phylogeny inferred from 72 plastid genes: a reanalysis of the phylogenetic localization of two paleopolyploid events and origin of novel chemical defenses

PREMISE OF THE STUDY - Previous phylogenetic studies employing molecular markers have yielded various insights into the evolutionary history across Brassicales, but many relationships between families remain poorly supported or unresolved. A recent phylotranscriptomic approach utilizing 1155 nuclear markers obtained robust estimates for relationships among 14 of 17 families. Here we report a complete family‐level phylogeny estimated using the plastid genome. METHODS - We conducted phylogenetic analyses on a concatenated data set comprising 44,926 bp...

Data from: Resting-state gamma-band power alterations in schizophrenia reveal E/I-balance abnormalities across illness-stages

Tineke Grent-'T-Jong, Joachim Gross, Jozien Goense, Michael Wibral, Ruchika Gajwani, Andrew I. Gumley, Stephen M. Lawrie, Matthias Schwannauer, Frauke Schultze-Lutter, Tobias Navarro Schröder, Dagmar Koethe, F. Markus Leweke, Wolf Singer & Peter J. Uhlhaas
We examined alterations in E/I-balance in schizophrenia (ScZ) through measurements of resting-state gamma-band activity in participants meeting clinical high-risk (CHR) criteria (n = 88), 21 first episode (FEP) patients and 34 chronic ScZ-patients. Furthermore, MRS-data were obtained in CHR-participants and matched controls. Magnetoencephalographic (MEG) resting-state activity was examined at source level and MEG-data were correlated with neuropsychological scores and clinical symptoms. CHR-participants were characterized by increased 64–90 Hz power. In contrast, FEP- and ScZ-patients showed...

Data from: Demographic expansion and genetic load of the halophyte model plant Eutrema salsugineum

Xiao-Juan Wang, Quan-Jun Hu, Xin-Yi Guo, Kun Wang, Da-Fu Ru, Dmitry A. German, Elizabeth A. Weretilnyk, Richard J. Abbott, Martin Lascoux & Jian-Quan Liu
Eutrema salsugineum is a widely distributed species, which provide a good model to study long-distance dispersal and accumulation of deleterious mutations. Based on population genomic data, we clarified demographic history of E. salsugineum and showed how deleterious alleles accumulated.

Data from: The sickle cell trait affects contact dynamics and endothelial cell activation in Plasmodium falciparum-infected erythrocytes

Christine Lansche, Anil K. Dasanna, Katharina Quadt, Benjamin Fröhlich, Dimitris Missirlis, Marilou Tetard, Benoit Gamain, Bernd Buchholz, Cecilia P. Sanchez, Motomu Tanaka, Ulrich S. Schwarz & Michael Lanzer
Sickle cell trait, a common hereditary blood disorder, protects carriers from severe disease in infections with the human malaria parasite Plasmodium falciparum. Protection is associated with a reduced capacity of parasitized erythrocytes to cytoadhere to the microvascular endothelium and cause vaso-occlusive events. However, the underpinning cellular and biomechanical processes are only partly understood and the impact on endothelial cell activation is unclear. Here, we show, by combining quantitative flow chamber experiments with multiscale computer simulations...

Data from: Contrasting heterozygosity-fitness correlations across life in a long-lived seabird

Coraline Bichet, Oscar Vedder, Hedwig Sauer-Gürth, Peter H. Becker, Michael Wink & Sandra Bouwhuis
Selection is a central force underlying evolutionary change and can vary in strength and direction, for example across time and space. The fitness consequences of individual genetic diversity have often been investigated by testing for multi-locus heterozygosity-fitness correlations (HFCs), but few studies have been able to assess HFCs across life stages and in both sexes. Here, we test for HFCs using a 26-year longitudinal individual-based dataset from a large population of a long-lived seabird (the...
