Tracking the ancestry of known and ‘ghost’ homeologous subgenomes in model grass Brachypodium polyploids

Rubén Sancho, Luis Ángel Inda, Antonio Díaz-Pérez, David L Des Marais, Sean Gordon, John Vogel, Joanna Lusinska, Robert Hasterok, Bruno Contreras-Moreira & Pilar Catalán
Unraveling the evolution of plant polyploids is a challenge when their diploid progenitor species are extinct or unknown or when genome sequences of known progenitors are unavailable. Existing subgenome identification methods cannot adequately infer the homeologous genomes that are present in the allopolyploids if they do not take into account the potential existence of unknown progenitors. We addressed this challenge in the widely distributed dysploid grass genus Brachypodium, which is a model genus for temperate...

Measurements of bite traces on bones

Grzegorz Sadlok
Carnivores make traces on bones with their teeth when feeding. A true predatory bite trace (predichnia) forms when a predator catches and kills its prey or attempts to do so. Both predators and scavengers may leave their non-predatory feeding traces during postmortem food processing. Despite the interpretative uncertainties as to the ethology such ichnofossils may represent, the bite traces have been traditionally classified as predichnia – traces of predation. Previously, there was no alternative ethological...

Dataset from the analysis of the expression of oxidative stress-related genes and the activity of their molecular counterparts in bacterial cells treated with metallic nanoparticles

Oliwia Metryka, Daniel Wasilkowski & Agnieszka Mrozik
This dataset contains raw data from the analyses published in the article entitled “Evaluation of the effects of Ag, Cu, ZnO and TiO2 nanoparticles on the expression level of oxidative stress-related genes and the activity of antioxidant enzymes in Escherichia coli, Bacillus cereus and Staphylococcus epidermidis” in International Journal of Molecular Sciences 23 (9):4966 (https://doi.org/10.3390/ijms23094966). The included data consists of results collected for gene expression studies using RT-qPCR reaction for selected bacterial genes of Escherichia...

Raw data from microCT tomography of Ausichicrinites zelenskyyi

Fossil comatulids, referred to as feather stars, are mostly known from highly disarticulated specimens. A single isolated element (centrodorsal) has been the basis for taxonomic description of a vast majority of fossil comatulids. Here, we report a nearly complete, and thus extremely rare, comatulid from the Upper Jurassic (Tithonian) of the Blue Nile Basin in central western Ethiopia that provides a unique insight into the morphology of comatulid arms and cirri. It is assigned to...
