Microorganisms are crucial in maintaining the sulfur cycle, influencing climate processes. Research has discovered diverse and multifunctional sulfate-reducing microorganisms, capable of simultaneous sulfate reduction and oxygen respiration, upending previous scientific consensus. (Artistic concept.) Study on environmentally relevant microorganisms shows greater diversity than previously assumed. A team of researchers has shown that there is an incredibly high biodiversity of environmentally relevant microorganisms in nature. This diversity is at least 4.5 times greater than previously known. The researchers recently published their findings in the prestigious journals Nature Communications and FEMS Microbiology Reviews. The hidden world of microorganisms is often overlooked, even though many climate-relevant processes are influenced by microorganisms, often associated with an incredible diversity of species within the groups of bacteria and archaea (“primitive bacteria”). For example, sulfate-reducing microorganisms convert a third of the organic carbon in marine sediments into carbon dioxide. This produces toxic hydrogen sulfide. On the positive side, sulfur-oxidizing microorganisms quickly use this as an energy source and render it harmless. “These processes also play an important role in lakes, bogs, and even in the human gut to keep nature and health in balance,” says Prof. Michael Pester, Head of the Department of Microorganisms at the Leibniz Institute DSMZ and Professor at the Institute of Microbiology at Technische Universität Braunschweig. A study examined the metabolism of one of these novel microorganisms in more detail, revealing a multifunctionality that was previously unattainable. Extremely high species diversity of sulphate-reducing microorganisms discovered. Sulfate reducers are now found in a total of 27 phyla within the bacteria and archaea instead of the six previously known. Credit: DSMZ The Sulfur Cycle’s Critical Balance The sulfur cycle is one of the most important and oldest biogeochemical cycles on our planet. At the same time, it is closely linked to the carbon and nitrogen cycles, underlining its importance. It is mainly driven by sulfate-reducing and sulphur-oxidising microorganisms. On a global scale, sulfate reducers convert about a third of the organic carbon that reaches the seafloor each year. In return, sulfur oxidizers consume about a quarter of the oxygen in marine sediments. When these ecosystems become unbalanced, the activities of these microorganisms can rapidly lead to oxygen depletion and the accumulation of toxic hydrogen sulfide. This leads to the formation of ‘dead zones’ where animals and plants can no longer survive. This not only causes economic damage, for example to fisheries, but also social damage through the destruction of important local recreational areas. It is therefore important to understand which microorganisms keep the sulfur cycle in balance and how they do this. The published results show that the species diversity of sulfate-reducing microorganisms includes at least 27 phyla (strains). Previously, only six phyla were known. By comparison, 40 phyla are currently known in the animal kingdom, with vertebrates belonging to only one phylum, the Chordata.

Credit: DSMZ   Newly Discovered Multifunctional Bacterial Species The researchers were able to assign one of these novel “sulfate reducers” to the little-researched phylum of acidobacteriota and to study it in a bioreactor. Using cutting-edge methods from environmental microbiology, they were able to show that these bacteria can obtain energy from both sulfate reduction and oxygen respiration. These two pathways are normally mutually exclusive in all known microorganisms. At the same time, the researchers were able to show that the sulfate-reducing acidobacteriota can break down complex plant carbohydrates such as pectin – another previously unknown property of “sulfate reducers.” The researchers have thus turned textbook knowledge on its head. They show that complex plant compounds can be degraded under oxygen exclusion not only by the coordinated interaction of different microorganisms, as previously thought, but also by a single bacterial species via a shortcut.

Researchers at the DSMZ and Technische Universität Braunschweig are currently investigating how the new findings affect the interplay of the carbon and sulfur cycles and how they are linked to climate-relevant processes.

This cross-section of a mouse heart (red) shows how well the gene therapy delivered sodium ion channel genes (cyan) to the target heart cells after researchers injected a virus with the genes into the mouse veins. Credit: Tianyu Wu, Duke University First approach to promote electrical excitation of heart cells in live mammals could lead to new gene therapy treatments for a wide range of heart diseases. Biomedical engineers at Duke University have demonstrated a gene therapy that helps heart muscle cells electrically activate in live mice. The first demonstration of its kind, the approach features engineered bacterial genes that code for sodium ion channels and could lead to therapies to treat a wide variety of electrical heart diseases and disorders. The results appeared online on February 2, 2022, in the journal Nature Communications. Long-lasting Effects on Heart Functionality “We were able to improve how well heart muscle cells can initiate and spread electrical activity, which is hard to accomplish with drugs or other tools,” said Nenad Bursac, professor of biomedical engineering at Duke. “The method we used to deliver genes in heart muscle cells of mice has been previously shown to persist for a long time, which means it could effectively help hearts that struggle to beat as regularly as they should.” Sodium-ion channels are proteins in the outer membranes of electrically excitable cells, such as heart or brain cells, that transmit electrical charges into the cell. In the heart, these channels tell muscle cells when to contract and pass the instruction along so that the organ pumps blood as a cohesive unit. Damaged heart cells, however, whether from disease or trauma, often lose all or part of their ability to transmit these signals and join the effort. Cardiac arrhythmias occur when heart muscle cells do not uniformly transmit electrical signals to pump blood in a cohesive, orderly fashion. The left video shows arrhythmic cells in tachycardia chaos, whereas the right video shows cells treated with the new gene therapy behaving normally, as they are much more difficult to push out of their regular heart beat activity. Credit: Tianyu Wu, Duke University One approach researchers can take to restore this functionality is gene therapy. By delivering the genes responsible for creating sodium channel proteins, the technique can produce more ion channels in the diseased cells to help boost their activity. In mammals, sodium channel genes are unfortunately too large to fit within the viruses currently used in modern gene therapies in humans. To skirt this issue, Bursac and his laboratory instead turned to smaller genes that code for similar sodium ion channels in bacteria. While these bacterial genes are different than their human counterparts, evolution has conserved many similarities in the channel design since multi-cellular organisms diverged from bacteria hundreds of millions of years ago. Successful Testing in Mouse Models Several years ago, Hung Nguyen, a former doctoral student in Bursac’s laboratory who now works for Fujifilm Diosynth Biotechnologies, mutated these bacterial genes so that the channels they encode could become active in human cells. In the new work, current doctoral student Tianyu Wu further optimized the content of the genes and combined them with a “promoter” that exclusively restricts channel production to heart muscle cells. The researchers then tested their approach by delivering a virus loaded with the bacterial gene into veins of a mouse to spread throughout the body. “We worked to find where the sodium ion channels were actually formed, and, as we hoped, we found that they only went into the working muscle cells of the heart within the atria and ventricles,” Wu said. “We also found that they did not end up in the heart cells that originate the heartbeat, which we also wanted to avoid.” This detailed image of a single mouse heart muscle cell shows its cell membrane expressing the new sodium ion channel genes (magenta) after researchers delivered the therapy through an injection into the mouse veins. Credit: Tianyu Wu, Duke University This gene therapy approach only delivers extra genes within a cell; it does not attempt to cut out, replace, or rewrite the existing DNA in any way. Scientists believe these types of delivered genes make proteins while floating freely within the cell, making use of the existing biochemical machinery. Previous research with this viral gene delivery approach suggests the transplanted genes should remain active for many years. As a proof of concept, tests on cells in a laboratory setting suggest that the treatment improves electrical excitability enough to prevent human abnormalities like arrhythmias. Within live mice, the results demonstrate that the sodium ion channels are active in the hearts, showing trends toward improved excitability. However, further tests are needed to measure how much of an improvement is made on the whole-heart level, and whether it is enough to rescue electrical function in damaged or diseased heart tissue to be used as a viable treatment. Future Directions and Potential Impact Moving forward, the researchers have already identified different bacterial sodium channel genes that work better in preliminary benchtop studies. The team is also working with the laboratories of Craig Henriquez, professor of biomedical engineering at Duke, and Andrew Landstrom, director of the Duke Pediatric Research Scholars Program, to test the ability of these genes to restore heart functionality in mouse models that mimic human heart diseases. “I think this work is really exciting,” Bursac said. “We have been harnessing what nature made billions of years ago to help humans with modern-day disease.” Reference: “Engineered Bacterial Voltage-Gated Sodium Channel Platform for Cardiac Gene Therapy” by Hung X.

Clockwise from right: A tiny, yolk-sac carrying hatchling with its large eyes; a juvenile; and an adult showing its toothed sucker. Credit: Kristen Tietjen Long considered a relic of deep evolutionary history, new fossils indicate that modern lamprey larvae are actually a relatively recent innovation. A new study out of the University of Chicago, the Canadian Museum of Nature, and the Albany Museum challenges a long-held hypothesis that the blind, filter-feeding larvae of modern lampreys are a holdover from the distant past, resembling the ancestors of all living vertebrates, including ourselves. The new fossil discoveries indicate that ancient lamprey hatchlings more closely resembled modern adult lampreys, and were completely unlike their modern larvae counterparts. The results were published today (March 10, 2021) in Nature. Lampreys — unusual jawless, eel-like, creatures — have long provided insights into vertebrate evolution, said first author Tetsuto Miyashita, PhD, formerly a Chicago Fellow at the University of Chicago and now a paleontologist at the Canadian Museum of Nature. “Lampreys have a preposterous life cycle,” he said. “Once hatched, the larvae bury themselves in the riverbed and filter feed before eventually metamorphosing into blood-sucking adults. They’re so different from adults that scientists originally thought they were a totally different group of fish. Fossil of the hatchling of Priscomyzon, from the Late Devonian around 360 million years ago. The hatchling is already equipped with large eyes and toothed sucker, which in modern lampreys only develop in adults. (The Canadian 25-cent coin offers a size comparison for the tiny fossil). Credit: Tetsuto Miyashita “Modern lamprey larvae have been used as a model of the ancestral condition that gave rise to the vertebrate lineages,” Miyashita continued. “They seemed primitive enough, comparable to wormy invertebrates, and their qualities matched the preferred narrative of vertebrate ancestry. But we didn’t have evidence that such a rudimentary form goes all the way back to the beginning of vertebrate evolution.” New Fossils Tell a Different Story Newly discovered fossils in Illinois, South Africa, and Montana are changing the story. Connecting the dots between dozens of specimens, the research team realized that different stages of the ancient lamprey lifecycle had been preserved, allowing paleontologists to track their growth from hatchling to adult. On some of the smallest specimens, about the size of a fingernail, soft tissue preservation even shows the remains of a yolk sac, indicating that the fossil record had captured these lampreys shortly after hatching. Crucially, these fossilized juveniles are quite unlike their modern counterparts (known as “ammocoetes”), and instead look more like modern adult lampreys, with large eyes and toothed sucker mouths. Most excitingly, this phenotype can be seen during the larval phase in multiple different species of ancient lamprey. “Remarkably, we’ve got enough specimens to reconstruct a trajectory from hatchling to adult in several independent lineages of early lampreys,” said Michael Coates, PhD, a professor in the Department of Organismal Biology and Anatomy at UChicago, “and they each show the same pattern: the larval form was like a miniature adult.” Tetsuto Miyashita (right) stands with researcher Rob Gess in 2016 atop the shale locality in Makhanda, South Africa that has yielded fossils of the 360 million-year-old Priscomyzon lamprey. Credit: Tetsuto Miyashita The researchers say that these results challenge the 150-year-old evolutionary narrative that modern lamprey larvae offer a glimpse of deep ancestral vertebrate conditions. By demonstrating that ancient lampreys never went through the same blind, filter-feeding stage seen in modern species, the researchers have falsified this cherished ancestral model. “We’ve basically removed lampreys from the position of the ancestral condition of vertebrates,” said Miyashita. “So now we need an alternative.” Seeking a New Ancestral Lineage After looking back at the fossil record, the team now believes that extinct armored fishes known as ostracoderms might instead represent better candidates for the root of the vertebrate family tree, whereas modern lamprey larvae are a more recent innovation. The team thinks the evolution of filter-feeding larvae may have allowed lampreys to populate rivers and lakes. Fossil lampreys reported in the new study all came from marine sediments, but modern lampreys mostly live in freshwater. The researchers say that this is the sort of discovery that can rewrite textbooks. “Lampreys are not quite the swimming time capsules that we once thought they were,” said Coates. “They remain important and essential for understanding the deep history of vertebrate diversity, but we also need to recognize that they, too, have evolved and specialized in their own right.” For more on this research, read Newly Discovered Fossils of Fish From Multiple Life Stages May “Rewrite Textbooks.” Reference: “Non-ammocoete larvae of Palaeozoic stem lampreys” by Tetsuto Miyashita, Robert W.

The team credits the hard work of their collaborators and co-authors, including Rob Gess, PhD of the Albany Museum in South Africa, with identifying multiple larval fossil samples, and Kristen Tietjen of the University of Kansas with CT scan and life reconstruction of fossil lampreys.
