A new sunflower family tree reveals that flower symmetry evolved multiple times independently. Species of the sunflower family with or without bilateral flower symmetry. Chrysanthemum lavandulifolium (upper left) and Artemisia annua (upper right) are closely related species from the same tribe; the former has bilaterally symmetric flowers (the rays) and the latter does not. Rudbeckia hirta (lower left) from the sunflower tribe has bilaterally symmetric flowers, and Eupatorium chinense (lower right) from the Eupatorieae tribe does not; these two tribes are closely related groups. A sunflower (center) shows flowers with bilateral symmetry (the large petal-like flowers in the outer row) and without (the small flowers in the inner rows). Credit: Guojin Zhang, Ma laboratory, Penn State The sunflower family tree revealed that flower symmetry evolved multiple times independently, a process called convergent evolution, among the members of this large plant family, according to a new analysis. The research team, led by a Penn State biologist, resolved more of the finer branches of the family tree, providing insight into how the sunflower family — which includes asters, daisies, and food crops like lettuce and artichoke — evolved. A paper describing the analysis and findings, which researchers said may help identify useful traits to selectively breed plants with more desirable characteristics, appeared online in the journal Plant Communication. “Convergent evolution describes the independent evolution of what appears to be the same trait in different species, like wings in birds and bats,” said Hong Ma, Huck Chair in Plant Reproductive Development and Evolution, professor of biology in the Eberly College of Science at Penn State and the leader of the research team. “This can make it difficult to determine how closely related two species are by comparing their traits, so having a detailed family tree based on DNA sequence is crucial to understanding how and when these traits evolved.” Advances in Sunflower Family Genealogy The sunflower head, for example, is actually a composite composed of multiple much smaller flowers. While the head is generally radially symmetric — it can be divided into two equal halves in multiple directions like a starfish or a pie — the individual flowers can have different forms of symmetry. According to the new study, bilateral symmetry — where there is only one line that divides the flower into two equal halves — has evolved and been lost multiple times independently in sunflowers over evolutionary history. The researchers found that this convergent evolution is likely related to changes in the number of copies and the expression patterns of the floral regulatory gene, CYC2. In recent years, many family trees for a group of related species have been built by extensively using transcriptomes, which are the genetic sequences of essentially all of the genes expressed by a species, the researchers explained. Transcriptomes are easier to acquire than high-quality whole-genome sequences for a species but are still difficult and costly to prepare and require fresh plant samples. To increase the number of species available for comparison the team turned to low-coverage genome sequences, which are produced through a process called genome skimming and are relatively inexpensive and easy to prepare, even from dried plant samples. “To get an accurate whole-genome sequence for a species, each letter of its DNA alphabet must be read — or covered — multiple times to minimize errors,” Ma said. “For the purposes of building a family tree, we show in this paper that we can get away with lower coverage genome sequences. This allowed us to increase the number of species in our analysis, which, in turn, allowed us to resolve more of the finer branches on the sunflower family tree.” The team used a combination of publicly available and newly generated transcriptomes, along with a large number of newly obtained skimmed genomes, for a total of 706 species with representatives from 16 subfamilies, 41 tribes, and 144 subtribe-level groups in the sunflower family. The subfamilies are major subdivisions of the family, while the tribes and subtribe can contain one or more of genera, which is the classification level just above the species. “Previous versions of the sunflower family tree had established the relationships among most of the subfamilies and many tribes, which are equivalent to the main branches of a tree,” Ma said. “With our increased sample size, we were able to resolve more of the smaller branches and twigs at the subtribe and genus level. This higher-resolution tree allowed us to reconstruct where and when traits like flower symmetry evolved, demonstrating that bilateral symmetry must have evolved many times independently.” Molecular Insights and Future Directions The team also studied the molecular evolution of genes involved in flower development among sunflowers. They found that one of these genes, CYC2, which is found in multiple copies in the genomes of each species, was activated in species with bilaterally symmetric flowers, suggesting that it might be part of the molecular basis for the convergent evolution of this trait. To further test this, the team performed experiments to quantify CYC2 gene expression in the flowers of species with different types of symmetry. “Our analysis showed a clear relationship between CYC2 expression and flower symmetry, suggesting that changes in how these genes are used in various sunflower species is likely involved in the convergent evolution observed in the family,” Ma said. “The sunflower family is one of the two largest families of flowering plants containing over 28,000 species, including many economically important agricultural and horticultural species. Understanding how these species are related to one another allows us to determine how and when their traits evolved. This knowledge could also be used to identify useful traits that could be bred into domesticated species from closely related wild ones.” Reference: “Nuclear phylogenomics of Asteraceae with increased sampling provides new insights into convergent morphological and molecular evolution” by Guojin Zhang, Junbo Yang, Caifei Zhang, Bohan Jiao, Jose L.

Saber-toothed predators, like the infamous Smilodon, evolved their iconic teeth repeatedly as optimal hunting tools, a study finds, revealing a surprising diversity in their dental structures and hunting tactics. Researchers have uncovered why the formidable teeth of saber-toothed predators like Smilodon were evolutionarily advantageous, using innovative techniques like 3D-printed tooth replicas and computer simulations. Their study not only highlights the diversity in tooth shapes and hunting strategies but also discusses the species’ susceptibility to extinction and its implications for evolutionary biology. Evolutionary Advantage of Saber-Toothed Predators Saber-toothed predators, famously represented by the iconic Smilodon, evolved independently across multiple mammal groups. A new study published today (January 9) in Current Biology sheds light on why: these distinctive teeth were “functionally optimal,” making them highly effective for puncturing prey. The research, led by scientists from the University of Bristol in collaboration with Monash University, found that the long, sharp, blade-like teeth of saber-toothed predators provided a significant advantage as specialized tools for hunting and capturing prey. The findings not only explain why saber-toothed adaptations emerged at least five separate times in mammals but also offer insights into their eventual extinction. The teeth, while highly specialized, may have acted as an “evolutionary ratchet,” enhancing hunting success but leaving these predators more vulnerable to extinction when ecosystems shifted, and prey became scarce. Graphic showing functional optimality drives repeated evolution of extreme sabertooth forms. Credit: Tahlia Pollock The Balance of Saber-Tooth Traits The team set out to test whether the saber-tooth shape was an optimal balance between the two competing needs: sharp and slender enough to effectively puncture prey and blunt and robust enough to resist breaking. Using 3D-printed steel tooth replicas in a series of biting experiments and advanced computer simulations, they analyzed the shape and performance of 95 different carnivorous mammal teeth, including 25 saber-toothed species. Lead author Dr. Tahlia Pollock, part of the Palaeobiology Research Group in Bristol’s School of Earth Sciences, explained: “Our study helps us better understand how extreme adaptations evolve – not just in saber-toothed predators but across nature. “By combining biomechanics and evolutionary theory, we can uncover how natural selection shapes animals to perform specific tasks.” Another key finding challenges the traditional idea that saber-toothed predators fall into just two categories: ‘dirk-toothed’ and ‘scimitar-toothed’. Instead, the research uncovered a spectrum of saber-tooth shapes, from the long, curved teeth of Barbourofelis fricki to the straighter, more robust teeth of Dinofelis barlowi. This supports a growing body of research suggesting a greater diversity of hunting strategies among these predators than previously thought. Future Research and Implications Looking ahead, the team plans to expand their analysis to include all tooth types, aiming to uncover the biomechanical trade-offs that shaped the evolution of diverse dental structures across the animal kingdom. “The findings not only deepen our understanding of saber-toothed predators but also have broader implications for evolutionary biology and biomechanics,” added Professor Alistair Evans, from the School of Biological Sciences at Monash University. “Insights from this research could even help inform bioinspired designs in engineering.” Reference: “Functional optimality underpins the repeated evolution of the extreme “saber-tooth” morphology” by Tahlia I.

Phages can sense bacterial DNA damage, which triggers them to replicate and jump ship. Viruses may be ‘watching’ you – some microbes lie in wait until their hosts unintentionally give them the signal to start multiplying and kill them. Especially after more than two years of the COVID-19 pandemic, many people picture a virus as a nasty spiked ball – essentially a mindless killer that gets into a cell and hijacks its machinery to create a gazillion copies of itself before bursting out. For many viruses, including the coronavirus that causes COVID-19, the “mindless killer” moniker is essentially true. However, there’s more to virus biology than meets the eye. A suitable illustration is HIV, the virus that causes AIDS. HIV is a retrovirus that does not immediately go on a killing spree when it enters a cell. Instead, it integrates itself into your chromosomes and chills, waiting for the proper opportunity to command the cell to make copies of it and burst out to infect other immune cells and eventually cause AIDS. Bacteriophages, or simply phages, are naturally occurring viruses that attack and kill bacteria. They cannot infect human cells. Phages are extremely diverse and exist everywhere in the environment, including in our bodies. In fact, humans contain more phages than human cells. A phage has three main parts: a head, a sheath, and a tail. The phage uses its tail to attach to a bacterial cell. They use the bacteria to replicate themselves. After finding a “matching” bacterial cell, the phage injects its genetic material, hijacking the system normally used for bacterial reproduction. Instead the system will make thousands more phages, which ultimately burst the bacterial cell, releasing it into the environment. Exactly what moment HIV is waiting for is not clear, as it’s still an area of active study. However, research on other viruses has long indicated that these pathogens can be quite “thoughtful” about killing. Of course, viruses cannot think the way you and I do. But, as it turns out, evolution has bestowed them with some pretty elaborate decision-making mechanisms. For example, some viruses will choose to leave the cell they have been residing in if they detect DNA damage. Not even viruses, it appears, like to stay on a sinking ship. For over two decades, my laboratory has been studying the molecular biology of bacteriophages, or phages for short, the viruses that infect bacteria. Recently, my colleagues and I demonstrated that phages can listen for key cellular signals to help them in their decision-making. Even worse, they can use the cell’s own “ears” to do the listening for them. Escaping DNA Damage If the enemy of your enemy is your friend, phages are certainly your friends. Phages control bacterial populations in nature, and clinicians are increasingly using them to treat bacterial infections that do not respond to antibiotics. The best-studied phage, lambda, works a bit like HIV. Upon entering the bacterial cell, lambda decides whether to replicate and kill the cell outright, like most viruses do, or to integrate itself into the cell’s chromosome, as HIV does. If the latter, lambda harmlessly replicates with its host each time the bacteria divides. This video shows a lambda phage infecting E. coli. However, like HIV, lambda is not just sitting idle. It uses a special protein called CI like a stethoscope to listen for signs of DNA damage within the bacterial cell. If the bacterium’s DNA gets compromised, that’s bad news for the lambda phage nested within it. Damaged DNA leads straight to evolution’s landfill because it’s useless for the phage that needs it to reproduce. So lambda turns on its replication genes, makes copies of itself, and bursts out of the cell to look for other undamaged cells to infect. Tapping the Cell’s Communication System Instead of gathering intel with their own proteins, some phages tap the infected cell’s very own DNA damage sensor: LexA. Proteins like CI and LexA are transcription factors that turn genes on and off by binding to specific genetic patterns within the DNA instruction book that is the chromosome. Some phages like Coliphage 186 have figured out that they don’t need their own viral CI protein if they have a short DNA sequence in their chromosomes that bacterial LexA can bind to. Upon detecting DNA damage, LexA will activate the phage’s replicate-and-kill genes, essentially double-crossing the cell into committing suicide while allowing the phage to escape. Researchers first reported CI’s role in phage decision-making in the 1980s and Coliphage 186’s counterintelligence trick in the late 1990s. Since then, there have been a few other reports of phages tapping bacterial communication systems. One example is phage phi29, which exploits its host’s transcription factor to detect when the bacterium is getting ready to generate a spore, or a kind of bacterial egg capable of surviving extreme environments. Phi29 instructs the cell to package its DNA into the spore, killing the budding bacteria once the spore germinates. In recently published research, my colleagues and I show that several groups of phages have independently evolved the ability to tap into yet another bacterial communication system: the CtrA protein. CtrA integrates multiple internal and external signals to set in motion different developmental processes in bacteria. Key among these is the production of bacterial appendages called flagella and pili. As it turns out, these phages attach themselves to the pili and flagella of bacteria in order to infect them. Our leading hypothesis is that phages use CtrA to guesstimate when there will be enough bacteria nearby sporting pili and flagella that they can readily infect. A pretty smart trick for a “mindless killer.” These aren’t the only phages that make elaborate decisions – all without the benefit of even having a brain. Some phages that infect Bacillus bacteria produce a small molecule each time they infect a cell. The phages can sense this molecule and use it to count the number of phage infections taking place around them. Like alien invaders, this count helps decide when they should switch on their replicate-and-kill genes, killing only when hosts are relatively abundant. This way, the phages make sure that they never run out of hosts to infect and guarantee their own long-term survival. Countering Viral Counterintelligence A good question is why you should care about the counterintelligence ops run by bacterial viruses. While bacteria are very different from people, the viruses that infect them are not that different from the viruses that infect humans. Pretty much every single trick played by phages has later been shown to be used by viruses that infect humans. If a phage can tap bacterial communication lines, why wouldn’t a human virus tap yours? So far, scientists don’t know what human viruses could be listening for if they hijack these lines, but there are plenty of conceivable options. I believe that, like phages, human viruses could potentially be able to count their numbers to strategize, detect cell growth and tissue formation, and even monitor immune responses. For now, these possibilities are only speculation, but scientific investigation is underway to investigate. Having viruses listening to your cells’ private conversations is not the rosiest of pictures, but it’s not without a silver lining. As intelligence agencies all around the world know quite well, counterintelligence only works when it’s covert. Once detected, the system can very easily be exploited to feed misinformation to your enemy. Similarly, I believe that future antiviral therapies may be able to combine conventional artillery, like antivirals that prevent viral replication, with information warfare trickery, such as making the virus believe the cell it is in belongs to a different tissue. But, hush, don’t tell anybody. Viruses could be listening! Written by Ivan Erill, Associate Professor of Biological Sciences, University of Maryland, Baltimore County.
