Life reconstruction of the new Cretaceous fossil turtle species Pleurochayah appalachius from the Arlington Archosaur Site in the Woodbine Group of Texas. Credit: Brent Adrian/Midwestern University The discovery of a new species of ancient turtle is shedding light on hard-to-track reptile migrations about 100 million years ago. Pleurochayah appalachius, a bothremydid turtle adapted for coastal life, is described in a new paper published by a multi-institution research group in the journal Scientific Reports. P. appalachius was discovered at the Arlington Archosaur Site (AAS) of Texas, which preserves the remnants of an ancient Late Cretaceous river delta that once existed in the Dallas-Fort Worth area and is also known for discoveries of fossil crocodyliformes and dinosaurs. P. appalachius belonged to an extinct lineage of pleurodiran (side-necked) turtles referred to as the Bothremydidae, a diverse and geographically widespread clade that occupied a wide range of ecological niches. The group originated in the southern continent of Gondwana, migrating to northern continents beginning in the Early Cretaceous. P. appalachius represents one of the earliest examples of intercontinental dispersals by the group and is the oldest bothremydid found in North America and Laurasian sediments. Its species name derives from the eastern North American subcontinent Appalachia, which was separated from Laramidia in the west by the Western Interior Seaway during the Late Cretaceous. Pleurochayah appalachius had an intriguing combination of morphological adaptations to a highly aquatic lifestyle that likely facilitated its long-distance migration. Its humerus (upper arm bone) shows large bony attachments for muscles that support a powerful recovery from swimming strokes. The functional morphology of the bone also indicates that P. appalachius likely utilized an aquatic rowing mode of swimming, as opposed to the flapping motion of modern sea turtles. The paleohistology (microanatomy) of its shell bone reveals a comparatively thick external compared to internal cortex, similar to later marine-adapted bothremydid species. However, its marine adaptations are not as derived as in later bothremydids, which are found throughout the fossil record of North American later in the Late Cretaceous. The cranium of P. appalachius has a unique combination of primitive and derived traits that it shares with other bothremydid species. It shares most characteristics with two of the basal bothremydid clades, Cearachelyini and Kurmademydini. A phylogenetic analysis places P. appalachius as a basal member of the bothremydid clade, and an outgroup to the more derived Bothremydini and Taphrosphyini tribes. “This discovery provides the earliest evidence of sidenecked turtles in North America and expands our understanding of the first migrations of the extinct bothremydids. It further establishes the Arlington Archosaur Site as an important fossil unit that is revealing the foundations of an endemic Appalachian fauna,” said Brent Adrian, Senior Research Specialist, Anatomy, at the Midwestern University College of Graduate Studies and the lead author of the study.

DOI: 10.1038/s41598-021-88905-1 The AAS is a prolific fossil locality found in the middle of a suburban subdivision. The site preserves remnants of an ancient Late Cretaceous river delta around 96 million years ago in what is today the Dallas-Fort Worth area. It preserves a record of a freshwater wetland that sat near the shore of a large peninsula, including a diverse assemblage of crocodile relatives, dinosaurs, amphibians, mammals, fish, invertebrates, and plants, several of which are also new species awaiting description. The research team describing these discoveries includes Brent Adrian, Dr. Heather F. Smith, and Dr. Ari Grossman from Midwestern University in Glendale, Arizona, and Dr. Christopher Noto from University of Wisconsin-Parkside. Work at the Arlington Archosaur Site is supported in part by the National Geographic Society, who provided a grant to complete field work at the site, and the Perot Museum of Nature and Science in Dallas, who curates the fossils found at the site. Scientific Reports is a member of the Nature Publishing Group.

Credit: Nicolas Guex © UNIL New research reveals that both the excess and the deficiency of a single protein can lead to severe intellectual deficiencies. The discovery offers critical insights for early diagnosis of a rare developmental disorder. A team of scientists presents a major step forward in the detection of a rare genetic disease. For the first time, the researchers show that both the accumulation and the deficiency of the so-called AFF3 protein are detrimental to development. The research was led by Alexandre Reymond, an expert in human genetics at the Center for Integrative Genomics (CIG) and professor at the Faculty of Biology and Medicine (FBM) of the University of Lausanne (UNIL). The research, published today (May 30) in Genome Medicine, follows on from the group’s 2021 discovery of the KINSSHIP syndrome, caused by mutations in the AFF3 gene and resulting in intellectual disability, an increased risk for epilepsy, kidney malformations, and bone deformation in affected children. Discovery of the genetic cause of KINSSHIP syndrome KINSSHIP syndrome affects about thirty individuals worldwide. As a result, there are few documented cases and understanding of the disease remains limited, making early and accurate diagnosis challenging. “In our previous study we demonstrated that this pathology resulted from an abnormal accumulation of the AFF3 protein. Meanwhile, available genetic data from individuals of the general population suggested that a lack of this same protein could be similarly deleterious,” explains Dr. Sissy Bassani, a postdoctoral researcher in Professor Reymond’s team and the lead author of the current study. Large genome database points researchers to a new hypothesis The geneticists formulated their hypothesis using gnomAD, a database containing genome sequences from several hundred thousand unrelated individuals. By mining the available data for AFF3 variants, the scientists found that loss-of-function mutations in this gene are rare, indicating their likely harmful nature. This implies that this gene plays a critical role and that its loss likely has detrimental consequences for the organism. To test their hypothesis, the authors searched for individuals with only one copy of the gene, instead of the two normally present in the human genome. Collaborating with researchers from nine different countries across Europe and North America, they identified 21 patients with such an anomaly. They all showed similar but less severe symptoms than those of KINSSHIP syndrome patients. Experiments reveal the developmental impact of AFF3 gene mutations To demonstrate that both insufficient and excessive amounts of AFF3 are detrimental, the researchers used several different experimental systems: cells of patients, mice, and zebrafish. Artificially decreasing or increasing the protein quantity in zebrafish eggs revealed major developmental defects in the resulting fish embryos. “These results confirm that a precise amount of AFF3 is crucial for proper embryonic development and that mutations affecting its function and/or dosage cause severe malformations,” concludes Prof. Reymond. Impact for prenatal diagnostics The authors’ findings are an important advancement for the diagnosis of this rare disorder, as testing for AAF3 mutations during fetal development could improve early detection of these gene defects.

Researchers have discovered that Rhizobia bacteria, known for their symbiotic relationship with legumes, can also form similar partnerships with marine diatoms. This discovery, which sheds light on a significant portion of marine nitrogen fixation, has implications for both marine biology and agricultural technology. Credit: SciTechDaily.com A groundbreaking study reveals that Rhizobia bacteria can fix nitrogen in partnership with marine diatoms, a discovery that could have significant implications for agriculture and marine ecosystems. Nitrogen is an essential component of all living organisms. It is also the key element controlling the growth of crops on land, as well as the microscopic oceanic plants that produce half the oxygen on our planet. Atmospheric nitrogen gas is by far the largest pool of nitrogen, but plants cannot transform it into a usable form. Instead, crop plants like soybeans, peas and alfalfa (collectively known as legumes) have acquired Rhizobial bacterial partners that “fix” atmospheric nitrogen into ammonium. This partnership makes legumes one of the most important sources of proteins in food production. Scientists from the Max Planck Institute for Marine Microbiology in Bremen, Germany, now report that Rhizobia can also form similar partnerships with tiny marine plants called diatoms – a discovery that solves a long-standing marine mystery and that has potentially far-reaching agricultural applications.

Credit: Mertcan Esti/Max Planck Institute for Marine Microbiology, Bremen, Germany An enigmatic marine nitrogen fixer hiding within a diatom For many years it was assumed that most nitrogen fixation in the oceans was carried out by photosynthetic organisms called cyanobacteria. However, in vast regions of the ocean there are not enough cyanobacteria to account for measured nitrogen fixation. Thus, a controversy was sparked, with many scientists hypothesizing that non-cyanobacterial microorganisms must be responsible for the “missing” nitrogen fixation. “For years, we have been finding gene fragments encoding the nitrogen-fixing nitrogenase enzyme, which appeared to belong to one particular non-cyanobacterial nitrogen fixer,” says Marcel Kuypers, lead author on the study. “But, we couldn’t work out precisely who the enigmatic organism was and therefore had no idea whether it was important for nitrogen fixation.” A group of diatoms with their fluorescently-labeled symbionts. Credit: Mertcan Esti/Max Planck Institute for Marine Microbiology, Bremen, Germany In 2020, the scientists traveled from Bremen to the tropical North Atlantic to join an expedition involving two German research vessels. They collected hundreds of liters of seawater from the region, in which a large part of global marine nitrogen fixation takes place, hoping to both identify and quantify the importance of the mysterious nitrogen fixer. It took them the next three years to finally puzzle together its genome. “It was a long and painstaking piece of detective work,” says Bernhard Tschitschko, first author of the study and an expert in bioinformatics, “but ultimately, the genome solved many mysteries.” The first was the identity of the organism, “While we knew that the nitrogenase gene originated from a Vibrio-related bacterium, unexpectedly, the organism itself was closely related to the Rhizobia that live in symbiosis with legumes,” explains Tschitschko. Together with its surprisingly small genome, this raised the possibility that the marine Rhizobia might be a symbiont. The first known symbiosis of this kind Spurred on by these discoveries, the authors developed a genetic probe that could be used to fluorescently label the Rhizobia. Once they applied it to the original seawater samples collected from the North Atlantic, their suspicions about it being a symbiont were quickly confirmed. “We were finding sets of four Rhizobia, always sitting in the same spot inside the diatoms,” says Kuypers, “It was very exciting as this is the first known symbiosis between a diatom and a non-cyanobacterial nitrogen fixer.” The scientists named the newly discovered symbiont Candidatus Tectiglobus diatomicola. Having finally worked out the identity of the missing nitrogen fixer, they focused their attention on working out how the bacteria and diatom live in partnership. Using a technology called nanoSIMS, they could show that the Rhizobia exchanges fixed nitrogen with the diatom in return for carbon. And it puts a lot of effort into it: “In order to support the diatom’s growth, the bacterium fixes 100-fold more nitrogen than it needs for itself,” Wiebke Mohr, one of the scientists on the paper explains.

Credit: Wiebke Mohr/Max Planck Institute for Marine Microbiology, Bremen, Germany A crucial role in sustaining marine productivity Next the team turned back to the oceans to discover how widespread the new symbiosis might be in the environment. It quickly turned out that the newly discovered partnership is found throughout the world’s oceans, especially in regions where cyanobacterial nitrogen fixers are rare. Thus, these tiny organisms are likely major players in total oceanic nitrogen fixation, and therefore play a crucial role in sustaining marine productivity and the global oceanic uptake of carbon dioxide. A key candidate for agricultural engineering? Aside from its importance to nitrogen fixation in the oceans, the discovery of the symbiosis hints at other exciting opportunities in the future. Kuypers is particularly excited about what the discovery means from an evolutionary perspective. “The evolutionary adaptations of Ca. T. diatomicola are very similar to the endosymbiotic cyanobacterium UCYN-A, which functions as an early-stage nitrogen-fixing organelle. Therefore, it’s really tempting to speculate that Ca. T. diatomicola and its diatom host might also be in the early stages of becoming a single organism.” Tschitschko agrees that the identity and organelle like nature of the symbiont is particularly intriguing, “So far, such organelles have only been shown to originate from the cyanobacteria, but the implications of finding them amongst the Rhizobiales are very exciting, considering that these bacteria are incredibly important for agriculture. The small size and organelle-like nature of the marine Rhizobiales means that it might be a key candidate to engineer nitrogen-fixing plants someday.” The scientists will now continue to study the newly discovered symbiosis and see if more like it also exist in the oceans.
