Credit: Taro Maeda Genome analysis reveals chloroplast acquisition without gene transfer in photosynthetic sea slugs. Plants, algae, and some bacteria are able to perform photosynthesis, which is the process of transforming sunlight energy into sugar. Animals are generally unable to use this process to acquire energy, but there are a few known exceptions to this. Some sea slugs take up chloroplasts from the algae that they consume into their cells. These chloroplasts retain their ability to perform photosynthetic activity within the animal cells for several months, and thus provide them with photosynthesis-derived nutrition. This process is called “kleptoplasty,” and it has attracted much attention due to its amazing uniqueness in making animals photosynthetic for over 50 years. A pressing question is how these sequestered chloroplasts retain their photosynthetic capability without algal nuclei. Since the genome of the algal nucleus encodes most of the proteins required for photosynthesis, chloroplasts isolated from algal cells instantly lose their photosynthetic capability. Nevertheless, algae-eating sea slugs retain this photosynthetic capability for months. There have been numerous debates about the mechanisms underlying the phenomenon of sequestered chloroplasts retaining photosynthetic capabilities over the long term. A widely accepted hypothesis accounting for kleptoplasty is the horizontal gene transfer of the photosynthesis genes from algae to sea slug. A team of researchers at the National Institute for Basic Biology (NIBB), in addition to collaborators from seven other Japanese institutions, have published the genome of the sea slug, Plakobranchus ocellatus type black, in eLife. “Since the sea slug is a non-model organism, its genome analysis was very tough in comparison to model organisms such as the mouse and the fruitfly. Furthermore, there was no high-quality genetic information for them. This situation consequently hindered the verification of the hypothesis of algae-derived horizontal gene transfer,” said Shuji Shigenobu, a genome scientist and professor at NIBB who is the corresponding author of the paper, “But we succeeded in accurately revealing the genome information of the sea slug”. Scientists are ready to settle the arguments concerning the horizontal transfer of algal genes to the animal nucleus based on newly unveiled genome data. “We looked at the genome very carefully, but we found no evidence of photosynthetic genes encoded on the sea slug genome, ” he said. “We are embarking upon a new challenge to answer the question: how does the sea slug retain this function without horizontal gene transfer?” said Taro Maeda, the first and co-corresponding author of the paper. “Our genome data also provides clues to this. We have found several candidate genes related to the long-term maintenance of photosynthetic activity. These genes related to protein metabolism, oxidative stress tolerance, and innate immunity should be subsequently highlighted in future studies.” The mechanisms underlying kleptoplasty are still elusive. Further understanding of this phenomenon may lead us to innovative biotechnologies, which, for example, could bestow photosynthetic abilities to other various animal cells in the future.

Carolina hawkmoth (Manduca sexta) feeding from white Mimulus mutant in flight chamber. Credit: Byers and Bradshaw, 2021 Research into the flower preferences of pollinating moths may have delivered a vital clue to the simple factors needed for the emergence of new species. Strong coevolutionary relationships between plants and animal pollinators have long been recognized as a potential driver of high rates of speciation in the 275,000 extant flowering plants. Shifts between pollinators, such as bumblebees, hummingbirds, hawkmoths, and bats, often coincide with plant speciation events. Each of these pollinator “guilds” is attracted by a different set of floral traits such as color, patterns, scent, shape, and nectar reward, collectively known as a pollination syndrome. So far, the detailed genetics of traits involved in pollinator shift-driven speciation remain unclear except in a few developing model systems. In a new study, researchers set out to engineer a pollinator switch in the lab that could mirror the origin of a new species in nature. They selected a species in the genus Mimulus (monkeyflowers) section Erythranthe where the evolution of hawkmoth pollination from hummingbird pollinated ancestors has not occurred. They made genetic changes to two flower color genes – effectively synthesizing a new Mimulus species with lower levels of the red pigment anthocyanin and yellow carotenoid pigments. These changes were based on observations in nature that most hummingbird-pollinated flowers are red and not easily visible to hawkmoths whose visual sensitivity does not extend to longer, red-light wavelengths. Hawkmoth-pollinated flowers, in contrast, are usually white or pale and highly reflective, adapted for detection by the crepuscular and nocturnal hawkmoths. Researchers tested the attractiveness of the four resulting color phenotypes – red, yellow, pink, and white – using lab-reared hawkmoths with no previous exposure to flowers. Hawkmoths strongly preferred “derived” non-red colors – yellow, pink, and white – over the ancestral red favored by hummingbirds and visited these pale colored flowers more often and for longer total periods over the experimental period. The study found that just these two simple genetic changes engineered by the researchers were required to affect the preference of hawkmoth pollinators. “We expected the hawkmoths to show some preference between colors, but their preferences were extremely strong,” said first author Dr. Kelsey Byers of the John Innes Centre and formerly based at the University of Washington (Seattle, WA, USA) where this research took place. “Our study shows that changes in flowering plant pollination syndrome can proceed through relatively few genetic changes, and this further suggests that only a few simple genetic changes might be required for the origin of a new species,” she added. Charles Darwin – fascinated by what he described as the “abominable mystery” of diverse flowering plant species – famously predicted that the Malagasy star orchid (Angraecum sesquipedale) which has a white flower and 35cm nectar spur, must be pollinated by a (then undiscovered) hawkmoth with a 35cm proboscis. Exactly such a hawkmoth pollinator was discovered decades after his prediction, confirming his hypothesis. This study likewise inspires a prospective approach to the understanding of plant speciation by pollinator shift – one of making predictions and testing them experimentally using new trait combinations synthesized in the lab. This contrasts with the classic retrospective approach which involves comparing related plants with different pollinators for differences in key floral traits and the effects of these on pollinator preference. “We have shown that the critical steps towards the origin of a new, experimentally synthesized hawkmoth-pollinated plant species can be predicted based upon a fundamental knowledge of pollination syndromes and genetics,” said Dr. Byers. So far, the experiments have been confined to the laboratory using lab-reared insects and one potential future direction of the research is to test the hypothesis in nature with wild insects to determine if a novel species could persist in the external environment.

A view from the summit of Volcán Salín, one of three Andean volcanoes where researchers uncovered the mummified cadavers of mice. Analyses of the mummies, combined with the capture of live specimens, suggest that the rodents scaled the Mars-like peaks on their own — and are somehow managing to live on them. Credit: Jay Storz, University of Nebraska–Lincoln The study dismisses any connection to Incan rituals, suggesting that mice ascended independently. In the midst of the driest desert on Earth, atop 20,000-foot volcanoes, the environment was harsh and unforgiving. The temperatures remained perpetually below freezing, the oxygen levels were less than half of what is found at sea level, and the peaks were battered by gale-force winds that swept across the sparse, rocky terrain. So when archaeologists first reported stumbling across a few mouse cadavers during expeditions to several Andean peaks in the 1970s and ’80s, they figured, naturally, that the rodents must have hitched a ride with the Incas who once pilgrimaged a thousand-plus miles to what they considered sacred sites. Those apexes served as altars for Capacocha, the ritual sacrifice of children to several Incan gods. Maybe, the thinking went, the mice had scurried into firewood or other supplies hauled up the slopes by the Incas. Or they were among the animal sacrifices that sometimes accompanied the humans. “You can’t fault the archaeologists for thinking this way, because what other explanation is there?” said Jay Storz, a Willa Cather Professor of biological sciences at the University of Nebraska–Lincoln. “Nothing could be living up there, so they had to have been brought there.” A New Hypothesis Emerges But Storz would inadvertently cast doubt on the hypothesis in early 2020. Alongside friend and fellow mountaineer Mario Pérez Mamani, he captured a live specimen of leaf-eared mouse atop the 22,000-foot peak of Llullaillaco (zhoo-zhuh-ZHEYE’-koh), a volcano straddling the Chile-Argentina border. No mammal had ever been found living at such extreme altitude. Alongside the capture of more live specimens, Storz and his colleagues have now reported the discovery of 13 leaf-eared mouse cadavers across the summits of three neighboring volcanoes — Salín, Púlar, and Copiapó — that each stretch nearly 4 miles above sea level. “These are basically freeze-dried, mummified mice,” Storz said. Jay Storz, a professor of biological sciences at the University of Nebraska–Lincoln, works to excavate a mouse mummy on the summit of an Andean volcano. Analyses of 13 mummified cadavers, combined with the capture of live specimens, suggest that the rodents scaled the Mars-like peaks on their own — and are somehow managing to live on them. Credit: Mario Pérez Mamani Analyzing the baker’s dozen of mummies has only reinforced the team’s conviction that the seemingly modest mice ascended the volcanoes without Incan assistance. By measuring concentrations of carbon-14, an atom that decays at a known rate, the team determined that the eight mummies atop Salín and one on Copiapó died no more than a few decades ago, likely after 1955. The four mummies on Púlar perished, at most, 350 years ago — a full century after the last of the Incan empire fell to Spanish invaders. “It now seems more and more clear,” Storz said, “that the mice got there of their own accord.” Genetic Insights and Baffling Survival The mummified state of the mice also helped preserve their DNA, allowing Storz’s collaborators from the University of Montana to compare genetic variation among leaf-eared mice collected in the lowlands, midlands, and highlands of Atacama Desert. Analyzing that variation across members of a species can help trace the evolutionary history of populations separated by distance, barriers or, in this case, altitude. Storz and his colleagues wondered whether the genomes of the skyscraping, mummified mice might represent a distinct subpopulation of the leaf-eared rodent — one with a colonization history different from that of their lower-dwelling peers. “Our genomic data indicate no: that the mice from the summits, and those from the flanks or the base of the volcanoes in the surrounding desert terrain, are all one big happy family,” Storz said, citing it as more evidence that the mummies were not hitchhikers but mountaineers. In fact, the team found that two pairs of the leaf-eared mummies on Salín were closely related, possibly siblings or parents and offspring. And it noted another telltale: the equal ratio of males to females among the mummies. Combined with the recent discovery of other live specimens and mouse burrows in the heights of the Puna de Atacama, or Atacama Plateau, Storz said it seems that the leaf-eared mouse is not just touring the volcanic summits, but somehow living on them. “It’s exactly what you’d expect,” he said, “if you were to capture a set of mice from some localized area in an environment that’s habitable.” Unanswered Questions and Ongoing Research Which is bewildering, Storz said, given that the Puna de Atacama ranks among the most inhospitable locales on the planet — one so arid, cold, and oxygen-poor that NASA has visited the Atacama to practice searching for life on Mars. “Even at the base of the volcanoes, the mice are living in an extreme, Martian environment,” he said. “And then, on the summits of the volcanoes, it’s even more so. It feels like outer space. “It just boggles the mind that any kind of animal, let alone a warm-blooded mammal, could be surviving and functioning in that environment. When you experience it all firsthand, it even further impresses upon you: How in God’s name is anything living up there?” It’s one of a few questions that the researchers are continuing to pursue. Members of Storz’s lab and colleagues in Santiago, Chile, have since established colonies of leaf-eared mice collected from various altitudes. By acclimating each group to conditions that simulate the Puna de Atacama at 20,000 feet, the researchers hope to pinpoint whatever physiological adaptations are helping the rodents cope. Even more fundamental is the question of what would drive the mice to such heights in the first place. Like most small rodents, the leaf-eared mouse — which grows to about 2 ounces — spends a fair amount of its time, energy, and attention avoiding predators. And even in the Puna de Atacama, those predators are numerous: foxes, mountain lions, smaller cats, birds of prey. Could the dangers imposed by the Atacama summits — the near-absence of water, the seeming lack of food, the threat of freezing to death — really be worth the promise of escaping predation all together? “Certainly, if you’re hunkering down on top of a 6,000-meter volcano, you’re at least safe from that,” Storz said. “You just have other things to worry about. “But why they’re ascending to these extreme elevations is still a mystery.” Reference: “Genomic insights into the mystery of mouse mummies on the summits of Atacama volcanoes” by Jay F.
