At first glance, the slightly murky waters in the tube look like a scoop of stormwater, replete with leaves, debris, and even lighter threads in the mix. But in the Petri dish, the thin vermicelli-like threads floating delicately above the leaf debris are revealed to actually be single bacterial cells, visible to the naked eye. Single filament of Ca. Thiomargarita magnifica. This image is associated with a June 2022 Science paper about a giant single-celled bacterium found in the mangroves of Guadeloupe titled, “A centimeter-long bacterium with DNA contained in metabolically active membrane-bound organelles.” Credit: Jean-Marie Volland The unusual size is very notable because bacteria aren’t usually visible without the assistance of a microscope. “It’s 5,000 times bigger than most bacteria. To put it into context, it would be like a human encountering another human as tall as Mount Everest,” said Jean-Marie Volland, a scientist with joint appointments at the U.S. Department of Energy (DOE) Joint Genome Institute (JGI), a DOE Office of Science User Facility located at Lawrence Berkeley National Laboratory (Berkeley Lab) and the Laboratory for Research in Complex Systems (LRC) in Menlo Park, California. In the June 24, 2022, issue of the journal Science, Volland, and colleagues, including researchers at the JGI and Berkeley Lab, LRC, and at the Université des Antilles in Guadeloupe, described the morphological and genomic features of this giant filamentous bacterium, along with its life cycle. For most bacteria, their DNA floats freely within the cytoplasm of their cells. This newly discovered species of bacteria keeps its DNA more organized. “The big surprise of the project was to realize that these genome copies that are spread throughout the whole cell are actually contained within a structure that has a membrane,” Volland said. “And this is very unexpected for a bacterium.” Strange Encounters in the Mangroves The bacterium itself was discovered by Olivier Gros, a marine biology professor at the Université des Antilles in Guadeloupe, in 2009. Gros’ research focuses on marine mangrove systems, and he was looking for sulfur-oxidizing symbionts in sulfur-rich mangrove sediments not far from his lab when he first encountered the bacteria. “When I saw them, I thought, ‘Strange,’” he said. “In the beginning, I thought it was just something curious, some white filaments that needed to be attached to something in the sediment like a leaf.” The lab conducted some microscopy studies over the next couple of years, and realized it was a sulfur-oxidizing prokaryote. Jean-Marie Volland describes the two take home messages associated with a Science paper characterizing giant bacteria in the French Caribbean. The work involved researchers from the JGI, Berkeley Lab, LRC Systems and Université des Antilles. Silvina Gonzalez-Rizzo, an associate professor of molecular biology at the Université des Antilles and a co-first author on the study, performed the 16S rRNA gene sequencing to identify and classify the prokaryote. “I thought they were eukaryotes; I didn’t think they were bacteria because they were so big with seemingly a lot of filaments,” she recalled of her first impression. “We realized they were unique because it looked like a single cell. The fact that they were a ‘macro’ microbe was fascinating!” “She understood that it was a bacterium belonging to the genus Thiomargarita,” Gros noted. “She named it Ca. Thiomargarita magnifica.” “Magnifica because magnus in Latin means big and I think it’s gorgeous like the French word magnifique,” Gonzalez-Rizzo explained. “This kind of discovery opens new questions about bacterial morphotypes that have never been studied before.” Characterizing the Giant Bacterium Volland got involved with the giant Thiomargarita bacteria when he returned to the Gros lab as a postdoctoral fellow. When he applied to the discovery-based position at the LRC that would see him working at the JGI, Gros allowed him to continue research on the project. At the JGI, Volland began studying Ca. T. magnifica in Tanja Woyke’s Single Cells Group to better understand what this sulfur-oxidizing, carbon fixing bacterium was doing in the mangroves. “Mangroves and their microbiomes are important ecosystems for carbon cycling. If you look at the space that they occupy on a global scale, it’s less than 1% of the coastal area worldwide. But when you then look at carbon storage, you’ll find that they contribute 10-15% of the carbon stored in coastal sediments,” said Woyke, who also heads the JGI’s Microbial Program and is one of the article’s senior authors. The team was also compelled to study these large bacteria in light of their potential interactions with other microorganisms. “We started this project under the JGI’s strategic thrust of inter-organismal interactions, because large sulfur bacteria have been shown to be hot spots for symbionts,” Woyke said. “Yet the project took us into a very different direction,” she added. Samples of Thiomargarita bacteria were collected amidst the mangroves in Guadeloupe.

Using various microscopy techniques, such as hard x-ray tomography, for instance, he visualized entire filaments up to 9.66 mm long and confirmed that they were indeed giant single cells rather than multicellular filaments, as is common in other large sulfur bacteria. He was also able to use imaging facilities available at Berkeley Lab, such as confocal laser scanning microscopy and transmission electron microscopy (TEM) to visualize the filaments and the cell membranes in more details. These techniques allowed him to observe novel, membrane-bound compartments that contain DNA clusters. He dubbed these organelles “pepins,” after the small seeds in fruits. DNA clusters were plentiful in the single cells. The team learned about the cell’s genomic complexity. As Volland noted, “The bacteria contain three times more genes than most bacteria and hundreds of thousands of genome copies (polyploidy) that are spread throughout the entire cell.” The JGI team then used single cell genomics to analyze five of the bacterial cells on the molecular level. They amplified, sequenced, and assembled the genomes. In parallel, Gros’ lab also used a labeling technique known as BONCAT to identify areas involved in protein-making activities, that confirmed that the entire bacterial cells were active.

So organisms that we think are very, very simple might have some surprises.” The LRC provided funding for Volland through grants from the John Templeton Foundation and the Gordon and Betty Moore Foundation. “This groundbreaking discovery highlights the importance of supporting fundamental, creative research projects to advance our understanding of the natural world,” added Sara Bender of the Gordon and Betty Moore Foundation. “We look forward to learning how the characterization of Ca. Thiomargarita magnifica challenges the current paradigm of what constitutes a bacterial cell and advances microbial research.” One Giant Bacterium, Multiple Research Questions For the team, characterizing Ca. Thiomargarita magnifica has paved the way for multiple new research questions. Among them, is the bacterium’s role in the mangrove ecosystem. “We know that it’s growing and thriving on top of the sediment of mangrove ecosystem in the Caribbean,” Volland said. “In terms of metabolism, it does chemosynthesis, which is a process analogous to photosynthesis for plants.” Another outstanding question is whether the new organelles named pepins played a role in the evolution of the Thiomargarita magnifica extreme size, and whether or not pepins are present in other bacterial species. The precise formation of pepins and how molecular processes within and outside of these structures occur and are regulated also remain to be studied.

Gros wants to look at other large bacteria. “You can find some TEM pictures and see what look like pepins so maybe people saw them but did not understand what they were. That will be very interesting to check, if the pepins are already present everywhere.” Reference: “A centimeter-long bacterium with DNA contained in metabolically active, membrane-bound organelles” by Jean-Marie Volland, Silvina Gonzalez-Rizzo, Olivier Gros, Tomáš Tyml, Natalia Ivanova, Frederik Schulz, Danielle Goudeau, Nathalie H.

Human brain cells take longer to mature than those of apes, giving them more time to divide and produce neurons. This delay is regulated by the gene ZEB2, which may explain why human brains are so much larger. A new study is the first to identify how human brains grow much larger, with three times as many neurons, compared with chimpanzee and gorilla brains. The study, led by researchers at the Medical Research Council (MRC) Laboratory of Molecular Biology in Cambridge, UK, identified a key molecular switch that can make ape brain organoids grow more like human organoids, and vice versa. The study, published in the journal Cell, compared ‘brain organoids’ — 3D tissues grown from stem cells which model early brain development — that were grown from human, gorilla, and chimpanzee stem cells. Similar to actual brains, the human brain organoids grew a lot larger than the organoids from other apes. Human brain organoids grow substantially bigger than gorilla and chimpanzee brain organoids (left to right). These brain organoids are 5 weeks old. Credit: S.Benito-Kwiecinski/MRC LMB/Cell Key Difference in Brain Size Dr. Madeline Lancaster, from the MRC Laboratory of Molecular Biology, who led the study, said: “This provides some of the first insight into what is different about the developing human brain that sets us apart from our closest living relatives, the other great apes. The most striking difference between us and other apes is just how incredibly big our brains are.” During the early stages of brain development, neurons are made by stem cells called neural progenitors. These progenitor cells initially have a cylindrical shape that makes it easy for them to split into identical daughter cells with the same shape. The more times the neural progenitor cells multiply at this stage, the more neurons there will be later. As the cells mature and slow their multiplication, they elongate, forming a shape like a stretched ice-cream cone. Human Cells Delay Maturation Previously, research in mice had shown that their neural progenitor cells mature into a conical shape and slow their multiplication within hours. Now, brain organoids have allowed researchers to uncover how this development happens in humans, gorillas, and chimpanzees. They found that in gorillas and chimpanzees this transition takes a long time, occurring over approximately five days. After only 5 days, gorilla neural progenitor cells have matured into a conical shape (right), while human cells (left) remain cylindrical. Credit: S.Benito-Kwiecinski/MRC LMB/Cell Human progenitors were even more delayed in this transition, taking around seven days. The human progenitor cells maintained their cylinder-like shape for longer than other apes and during this time they split more frequently, producing more cells. Shape Change Drives Brain Expansion This difference in the speed of transition from neural progenitors to neurons means that the human cells have more time to multiply. This could be largely responsible for the approximately three-fold greater number of neurons in human brains compared with gorilla or chimpanzee brains. Dr. Lancaster said: “We have found that a delayed change in the shape of cells in the early brain is enough to change the course of development, helping determine the numbers of neurons that are made. “It’s remarkable that a relatively simple evolutionary change in cell shape could have major consequences in brain evolution. I feel like we’ve really learnt something fundamental about the questions I’ve been interested in for as long as I can remember — what makes us human.” Dr. Madeline Lancaster and her team at the MRC Laboratory of Molecular Biology. Credit: MRC Laboratory of Molecular Biology ZEB2 Gene Regulates Brain Growth Timing To uncover the genetic mechanism driving these differences, the researchers compared gene expression — which genes are turned on and off — in the human brain organoids versus the other apes. They identified differences in a gene called ‘ZEB2’, which was turned on sooner in gorilla brain organoids than in the human organoids. To test the effects of the gene in gorilla progenitor cells, they delayed the effects of ZEB2. This slowed the maturation of the progenitor cells, making the gorilla brain organoids develop more similarly to human — slower and larger. Conversely, turning on the ZEB2 gene sooner in human progenitor cells promoted premature transition in human organoids, so that they developed more like ape organoids. The researchers note that organoids are a model and, like all models, do not to fully replicate real brains, especially mature brain function. But for fundamental questions about our evolution, these brain tissues in a dish provide an unprecedented view into key stages of brain development that would be impossible to study otherwise.

Modern human and archaic Neanderthal skulls side by side, showing difference in nasal height. Credit: Dr. Kaustubh Adhikari, UCL A study by University College London researchers discovered that humans inherited genetic material from Neanderthals, affecting nose shape. The gene responsible for a taller nose may have resulted from natural selection as ancient humans adapted to colder climates after leaving Africa. Humans inherited genetic material from Neanderthals that affects the shape of our noses, finds a new study led by University College London (UCL) researchers. The new Communications Biology study finds that a particular gene, which leads to a taller nose (from top to bottom), may have been the product of natural selection as ancient humans adapted to colder climates after leaving Africa. Co-corresponding author Dr Kaustubh Adhikari (UCL Genetics, Evolution & Environment and The Open University) said: “In the last 15 years, since the Neanderthal genome has been sequenced, we have been able to learn that our own ancestors apparently interbred with Neanderthals, leaving us with little bits of their DNA. “Here, we find that some DNA inherited from Neanderthals influences the shape of our faces. This could have been helpful to our ancestors, as it has been passed down for thousands of generations.” The study used data from more than 6,000 volunteers across Latin America, of mixed European, Native American and African ancestry, who are part of the UCL-led CANDELA study, which recruited from Brazil, Colombia, Chile, Mexico and Peru. The researchers compared genetic information from the participants to photographs of their faces – specifically looking at distances between points on their faces, such as the tip of the nose or the edge of the lips – to see how different facial traits were associated with the presence of different genetic markers. The researchers newly identified 33 genome regions associated with face shape, 26 of which they were able to replicate in comparisons with data from other ethnicities using participants in east Asia, Europe, or Africa. Natural Selection and Adaptation to Cold Climates In one genome region in particular, called ATF3, the researchers found that many people in their study with Native American ancestry (as well as others with east Asian ancestry from another cohort) had genetic material in this gene that was inherited from the Neanderthals, contributing to increased nasal height. They also found that this gene region has signs of natural selection, suggesting that it conferred an advantage for those carrying the genetic material. First author Dr Qing Li (Fudan University) said: “It has long been speculated that the shape of our noses is determined by natural selection; as our noses can help us to regulate the temperature and humidity of the air we breathe in, different shaped noses may be better suited to different climates that our ancestors lived in. The gene we have identified here may have been inherited from Neanderthals to help humans adapt to colder climates as our ancestors moved out of Africa.” Co-corresponding author Professor Andres Ruiz-Linares (Fudan University, UCL Genetics, Evolution & Environment, and Aix-Marseille University) added: “Most genetic studies of human diversity have investigated the genes of Europeans; our study’s diverse sample of Latin American participants broadens the reach of genetic study findings, helping us to better understand the genetics of all humans.” The finding is the second discovery of DNA from archaic humans, distinct from Homo sapiens, affecting our face shape. The same team discovered in a 2021 paper that a gene influencing lip shape was inherited from the ancient Denisovans. The study involved researchers based in the UK, China, France, Argentina, Chile, Peru, Colombia, Mexico, Germany, and Brazil.
