Mormon Fritillary butterflies (Speyeria mormonia) exhibit a striking wing color polymorphism throughout their range: typical morphs bear silver spots on their ventral surfaces and can co-occur with unsilvered morphs displaying a dull coloration.1 Through genome-wide association studies in two polymorphic populations, we fine-map this difference in silvering to the 3' region of the transcription factor gene optix. The expression of optix is confined to the unsilvered regions that surround the spots, and these patterns are transformed to a silver identity upon optix RNA interference (RNAi) knockdown, implicating optix as a repressor of silver scales in this butterfly. We show that the unsilvered optix haplotype shows signatures of recent selective sweeps and that this allele is shared with an unsilvered population of Speyeria hydaspe, suggesting that introgressions may facilitate the exchange of variants of adaptive potential across species. Remarkably, these findings parallel the role of allelic sharing and cis-regulatory modulation of optix in shaping the aposematic red patterns of Heliconius butterflies,2,3,4,5,6,7 a lineage that separated from Speyeria 45 million years ago.8 The genetic basis of adaptive variation can thus be more predictable than often presumed, even for traits that appear divergent across large evolutionary distances.","PeriodicalId":11359,"journal":{"name":"Current Biology","volume":"35 9","pages":"2154-2163.e7"},"PeriodicalIF":8.1,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143998651","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research gathered from model species, particularly Arabidopsis thaliana, has revealed that the nuclear auxin pathway controls many of these processes through transcriptional regulation. Recently, a non-transcriptional pathway based on rapid phosphorylation mediated by kinases has been described, complementing the understanding of the complexity of auxin-regulated processes. Phylogenetic inferences of both pathways indicate that only some of these components are conserved beyond land plants. This raises fundamental questions about the evolutionary origin of auxin responses and whether algal sisters share mechanistic features with land plants. Here, we explore auxin responses in the unicellular streptophyte alga Penium margaritaceum. By assessing physiological, transcriptomic, and cellular responses, we found that auxin triggers cell proliferation, gene regulation, and acceleration of cytoplasmic streaming. Notably, all these responses are also triggered by the structurally related tryptophan. These results identify shared auxin response features among land plants and algae and suggest that less chemically specific responses preceded the emergence of auxin-specific regulatory networks in land plants.","PeriodicalId":11359,"journal":{"name":"Current Biology","volume":"35 9","pages":"2078-2087.e4"},"PeriodicalIF":8.1,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12061043/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143982001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This uncertainty arises from spatiotemporal sampling inconsistency and data absence, which cause challenges in distinguishing between genuine biological trends and sampling artifacts. Consequently, there is an inherent interest in better quantifying the quality of the data and concomitant biases of the dinosaur fossil record. To elucidate the structure of this record and the nature of the biases impacting it, we integrate paleoclimatic, geographic, and fossil data within a Bayesian occupancy modeling framework to simultaneously estimate the probability of dinosaurs occupying and being detected in sites across North America throughout the latest Cretaceous for the first time. We find that apparent declines in occupancy generated from the raw fossil record do not match modeled occupancy probability, which generally remained stable throughout the latest Cretaceous. Instead, they coincide with decreased probability of detecting dinosaur occurrences, despite high overall sampling during this interval. By incorporating model covariates, we additionally reveal that detection probability is directly and significantly influenced by the available area of geological outcrop and modern land cover. Our findings offer evidence that traditional comparisons of diversity estimates between time intervals are likely inaccurate due to underlying structural issues in the geological record operating at both local and regional scales. This study underscores the utility of occupancy modeling as a novel approach in paleobiology for quantifying the impact of heterogeneous sampling on the available fossil record.","PeriodicalId":11359,"journal":{"name":"Current Biology","volume":"35 9","pages":"1973-1988.e6"},"PeriodicalIF":8.1,"publicationDate":"2025-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143967584","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We found that each mouse produced unique songs16,17,18 with reliable counter-singing response latencies, allowing for a vocal signature that can be distinguished by conspecifics. Although individual mice sang spontaneously and with remote partners, we found that pairs of mice within the same terrarium rarely engaged in short-latency counter-singing. We used song playback to demonstrate that counter-singing can most robustly be elicited at distances of ∼2 m, demonstrating the tendency of this species to preferentially interact with others in nearby home ranges.19 Finally, when an \"intruder\" mouse entered the environment during staged interactions, the resident mouse often responded aggressively by chasing the intruder and broadcasting songs from outside the safety of a shelter.

Their exquisite biomineralized skeletons left an extensive fossil record extremely valuable for biostratigraphic and paleo-environmental research. In contemporary oceans, there is growing evidence that Radiolaria are significant contributors to marine food webs and global biogeochemical cycles. Here we provide a comprehensive morpho-molecular framework to assess the extant diversity, biogeography, and evolutionary history of Radiolaria. Our analyses reveal that half of radiolarian diversity is morphologically undescribed, with a large part forming three hyper-diverse environmental clades, named Rad-A, Rad-B, and Rad-C. We suggest that most of this undescribed diversity comprises skeleton-less life forms or endosymbionts, explaining their elusive, yet abundant, nature. Phylogenetic analyses highlight the need for a major revision of high-level Radiolaria taxonomy, including placement of Collodaria within the order Nassellaria. Global metabarcoding surveys show that Radiolaria contributes more than 12% to the total eukaryotic community, displaying distinct biogeographic patterns with the skeleton-less lineages at depth and photosymbiont-bearing lineages in the surface. Fossil calibration of a molecular clock revealed the first appearance of Radiolaria ∼760 million years ago (mya), the development of the skeleton in the early Paleozoic (∼500 mya), and the onset of photosymbiotic relationships during the mid to late Mesozoic (∼140 mya), related to geological periods of oligotrophy and anoxia. The results presented here provide a robust framework for developing new perspectives on early eukaryotic diversification, paleo-environmental impacts on plankton evolution, and marine microbial ecology in rapidly evolving ecosystems.","PeriodicalId":11359,"journal":{"name":"Current Biology","volume":" ","pages":""},"PeriodicalIF":8.1,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143962542","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
