The Taiwan habu (Protobothrops mucrosquamatus) is an invasive species that has become well established in Okinawa. Credit: OIST/Steven Aird Startling new evidence shows mammal salivary glands and snake venom glands share a common genetic foundation. Venoms are a mixture of proteins that animals have weaponized for prey capture and self defense New research has found that snakes and mammals share a set of genes that have similar activity within salivary and venom gland tissue These common genes provide a crucial foundation for evolving venom by ensuring that the glands can produce high loads of functional proteins These findings provide the first direct evidence that venom glands evolved from early salivary glands Under the right evolutionary conditions, mammal salivary glands could be repurposed for a venomous function We are not venomous, and neither are mice – but within our genomes lurks that potential, suggest scientists from the Okinawa Institute of Science and Technology Graduate University (OIST) and the Australian National University. As reported in PNAS, the researchers found that the genetic foundation required for oral venom to evolve is present in both reptiles and mammals. The study also provides the first concrete evidence of an underlying molecular link between venom glands in snakes and salivary glands in mammals. “Venoms are a cocktail of proteins that animals have weaponized to immobilize and kill prey, as well as for self-defense,” said first author, Agneesh Barua, a PhD student at OIST. “What’s interesting about venom is that it has arisen in so many different animals: jellyfish, spiders, scorpions, snakes, and even some mammals. Although these animals evolved different ways to deliver venom, an oral system – where venom is injected through a bite – is one of the most common and well-studied.” But scientists are still zeroing in on the origin of oral venom. This latest research into snakes, a group of animals renowned and feared for their potent bite, now reveals oral venom’s ancient foundation. Previously, scientists have focused on the genes that code for the proteins that make up the toxic mixture. “However, many of the toxins currently found in venom were incorporated after the oral venom system was already established. We needed to look at the genes that were present before venom’s origin, genes which enabled the rise of venom systems,” Barua said. So instead, the team searched for genes that work alongside and interact strongly with the venom genes. The scientists used venom glands collected from the Taiwan habu snake – a pit viper found in Asia. The researchers identified around 3,000 of these ‘cooperating’ genes and found that they played important roles in protecting the cells from stress caused by producing lots of proteins. The genes were also key in regulating protein modification and folding. When proteins are made, the long chains of amino acids must fold together in a specific way. Just like a wrong fold when doing origami, one misstep prevents the protein from assuming the required shape needed for it to function properly. Misfolded proteins can also accumulate and damage cells. “The role of these genes in the unfolded protein response pathway makes a lot of sense as venoms are complex mixtures of proteins. So to ensure you can manufacture all these proteins, you need a robust system in place to make sure the proteins are folded correctly so they can function effectively,” explained Barua. The researchers then looked at the genomes of other creatures across the animal kingdom, including mammals like dogs, chimpanzees, and humans, and found that they contained their own versions of these genes. When the team looked at the salivary gland tissues within mammals, they found that the genes had a similar pattern of activity to that seen in snake venom glands. The scientists therefore think that salivary glands in mammals and venom glands in snakes share an ancient functional core that has been maintained since the two lineages split hundreds of millions of years ago. “Many scientists have intuitively believed this is true, but this is the first real solid evidence for the theory that venom glands evolved from early salivary glands,” said Barua. “And while snakes then went crazy, incorporating many different toxins into their venom and increasing the number of genes involved in producing venom, mammals like shrews produce simpler venom that has a high similarity to saliva.” The apparent ease with which the function of salivary glands can be repurposed to be venomous is startling – and could mean that scientists start looking at other mammals in an unsettling new light. “There were experiments in the 1980s that showed that male mice produce compounds in their saliva that are highly toxic when injected into rats,” said Barua. “If under certain ecological conditions, mice that produce more toxic proteins in their saliva have better reproductive success, then in a few thousand years, we might encounter venomous mice.” Whether mice are or are not on this evolutionary path is a matter that requires further investigation, but it certainly blurs the line between venomous and non-venomous species. And although very unlikely, if the right ecological conditions ever existed, humans too could become venomous. “It definitely gives a whole new meaning to a toxic person,” joked Barua.

Researchers have decoded the genome of Epulopiscium viviparus, a giant bacterium living in surgeonfish, revealing unique metabolic adaptations and energy production methods. This study offers potential applications in algae-based nutrition and energy. Credit: SciTechDaily.com A groundbreaking study of the giant bacterium Epulopiscium viviparus shows its unique energy production, promising future applications in algae utilization. Not all bacteria are created equal. Most are single-celled and tiny, a few ten-thousandths of a centimeter long. But bacteria of the Epulopiscium family are large enough to be seen with the naked eye and 1 million times the volume of their better-known cousins, E. coli. Discovery and Study of a Giant Bacterium In a study published recently in Proceedings of the National Academy of Sciences, researchers from Cornell and Lawrence Berkeley National Laboratory have for the first time described the full genome of one species of the family of giants, which they’ve named Epulopiscium viviparus. “This incredible giant bacterium is unique and interesting in so many ways: its enormous size, its mode of reproduction, the methods by which it meets its metabolic needs and more,” said Esther Angert, professor of microbiology in the College of Agriculture and Life Sciences, and corresponding author of the study. “Revealing the genomic potential of this organism just kind of blew our minds.” Micrograph of a group of Epulopiscium viviparus bacteria. Credit: Esther Angert Habitat and Characteristics The first member of the Epulopiscium family was discovered in 1985. All members of the species live symbiotically within the intestinal tracts of certain surgeonfish in tropical marine coral reef environments, such as the Great Barrier Reef and in the Red Sea. Because of its gargantuan size, scientists initially believed it was some distinct type of protozoan, Angert said. The name Epulopiscium comes from the Latin roots epulo, meaning “a guest,” and piscium, “of a fish.” While most bacteria reproduce by dividing themselves in half to create two offspring, E. viviparus create as many as 12 copies of themselves, which grow inside a parent cell and then get released, “active and swimming – viviparus means ‘live birth,’” Angert said. Research Methodology Studying these giant bacteria requires capturing the fish in which they live and preserving the cells or extracting DNA and RNA as quickly and carefully as possible, said Angert, who for decades has collaborated with fish biologists at Lizard Island Research Station in Australia to collect and study samples. Metabolic Insights The researchers were especially interested to learn how E. viviparus fuels its extreme metabolic needs. Bacteria that feed off nutrients in their environment, rather than creating their own energy from sunlight, generally fall into two camps: those that have access to oxygen and those that don’t. Without oxygen, bacteria often use fermentation to extract energy, and “fermenting organisms just don’t get as much bang for the buck from nutrients,” Angert said. Seeing that E. viviparus is indeed a fermenter just made the puzzle larger, as its huge size, extreme reproduction, and ability to swim would all require more energy, not less. Genetic Adaptations and Energy Production The researchers discovered that E. viviparus has modified its metabolism to make the most of its environment, by using a rare method to make energy and to move (the same swimming method is used by the bacteria that cause cholera), and by devoting a huge portion of its genetic code to making enzymes that can harvest the nutrients available in its host’s gut. Among the most highly produced enzymes are those used to make ATP, the energy currency of all cells. A highly folded membrane that runs along the outer edge of E. viviparus provides important space for the energy-producing and -transporting proteins, with some surprising similarities to how mitochondria function in the cells of more complex organisms, Angert said. “We all know that phrase ‘the mitochondria are the powerhouse of the cell,’” Angert said, “and amazingly, these membranes in E. viviparus have kind of converged on the same model as the mitochondria: They have a highly folded membrane that increases surface area where these energy-producing pumps can work, and that increased surface area creates a powerhouse of energy.” Potential Applications and Future Research This basic research has a host of potential future applications, particularly as E. viviparus has such effective strategies to make use of the nutrients found in algae, Angert said. Algae is a growing target for livestock feeds, renewable energy, and human nutrition, since its growth doesn’t compete with land-based agriculture.

Credit: Mareike Koppik The number of males has little bearing on a population’s growth, but they are important for purging bad mutations from the population. A few males are enough to fertilize all the females. The number of males, therefore, has little bearing on a population’s growth. However, they are important for purging bad mutations from the population. This is shown by a new Uppsala University study providing in-depth knowledge of the possible long-term genetic consequences of sexual selection. The results are published in the scientific journal Evolution Letters. The study supports the theory that in many animal species selection acting on males can impose the fortuitous benefit to the population of causing offspring to inherit healthy genes. Stiff competition among males results in selective elimination of individuals with many deleterious mutations, preventing them from passing on said mutations. This may exert positive long-term effects on a sexually reproducing population’s growth and persistence. “When deleterious mutations are purged from a population through rigorous selection in males, resulting in fewer males reproducing, the process can take place with little or no effect on population growth. This is because relatively few males suffice to fertilize all the females in a population, hence, whether those females are fertilized by few males or many males makes little or no difference to the number of offspring those females can produce, especially in species where the male doesn’t look after its own offspring. By contrast, such rigorous selection in females would result in fewer females reproducing, hence fewer offspring produced, which could lead to a massive population decline or even extinction,” says Karl Grieshop, evolutionary biologist at Canada’s University of Toronto and the study’s lead author. A Callosobruchus maculatus female (right) rejecting a male (left) mating attempt. Credit: Mareike Koppik The researchers used 16 genetic strains of seed beetle (Callosobruchus maculatus) to investigate how the inferred number of deleterious mutations in each affected the reproductive ability (fitness) of females and males. Through intensive inbreeding of strains followed by crosses among them, it was possible to quantify the cumulative effects of each strain’s unique set of mutations. By comparing the inbred strains to the crosses among them, the scientists were able to see that these mutations harmed both females and males nearly equally. However, when looking only at the crosses among strains, which is the more genetically variable setting that is more relevant to how selection would act in nature, these mutational effects were only manifest in male fitness. In the females, the deleterious effects of the mutations they carried were not detectable in this more genetically variable background, and would therefore not be purged effectively via female-specific selection in nature. “This indicates that although these mutations do have a detrimental effect on females’ reproduction, they are more effectively removed from the population by selection acting on male carriers than female carriers. Previous research from our group and others has succeeded in showing this effect by artificially inducing mutations, but this is the first direct evidence that it ensues for naturally occurring variants of genes,” Grieshop says. In the researchers’ view, their study sheds new light on the old question of why so many multicellular organisms use sexual reproduction. “Production of males causes a decrease in the reproductive capacity of a species, since males themselves contribute less than females to the production of offspring. The question, then, is why a species evolves to reproduce sexually, instead of just producing females through asexual reproduction. Our study shows that production of males, which may engage in intense competition for the chance to mate, enables faster purging of deleterious mutations from the population, which could thereby enable a healthier set of genes and higher reproductive capacity relative to asexual reproduction,” says David Berger, researcher and team leader at Uppsala University’s Department of Ecology and Genetics.
