Phylogeny and characteristics of ruminants Ruminants are a diverse group mammals that includes families containing well-known taxa such as deer, cows, goats. However, their evolutionary relationships have been contentious, the origins distinctive digestive systems headgear, including antlers horns (see Perspective by Ker Yang). To understand among ruminants, L. Chen et al. sequenced 44 species representing 6 performed phylogenetic analysis. From this analysis, they were able to resolve...
Polyploidy or whole-genome duplication (WGD) is a major event that drastically reshapes genome architecture and often assumed to be causally associated with organismal innovations radiations. The 2R hypothesis suggests two WGD events (1R 2R) occurred during early vertebrate evolution. However, the timing of relative divergence gnathostomes (jawed vertebrates) cyclostomes (jawless hagfishes lampreys) unresolved whether these underlie phenotypic diversification remains elusive. Here we present...
Abstract G-quadruplex (G4) structures have been predicted in the genomes of many organisms and proven to play regulatory roles diverse cellular activities. However, there is little information on evolutionary history distribution characteristics G4s. Here, whole-genome potential G4s were studied 37 evolutionarily representative species. During evolution, number, length, density generally increased. Immunofluorescence seven species confirmed G4s’ presence pattern. tended cluster chromosomes...
Guanine-rich and cytosine-rich DNA can form four-stranded secondary structures called G-quadruplex (G4) i-motif, respectively. These widely exist in genomes play important roles transcription, replication, translation protection of telomeres. In this study, G4 i-motif were identified the promoter transcription factor gene BmPOUM2, which regulates expression wing disc cuticle protein (BmWCP4) during metamorphosis. Disruption structure by base mutation, anti-sense oligonucleotides (ASOs) or...
Abstract Background The swimming crab, Portunus trituberculatus, is an important commercial species in China and widely distributed the coastal waters of Asia-Pacific countries.

Findings Here, we assembled first reference P. trituberculatus by combining short reads, Nanopore long Hi-C data. assembly size was 1.00 Gb with contig N50 length 4.12 Mb. In addition, BUSCO assessment indicated that...
Abstract Background The Southern Ocean is the coldest ocean on Earth but a hot spot of evolution. bottom-dwelling Eocene ancestor Antarctic notothenioid fishes survived polar marine glaciation and underwent adaptive radiation, forming >120 species that fill all water column niches today. Genome-wide changes enabling physiological adaptations rapid expansion notothenioids remain poorly understood. Results We sequenced compared 2 genomes—the cold-adapted neutrally buoyant toothfish...
Abstract The evolutionary and genetic origins of the specialized body plan flatfish are largely unclear. We analyzed genomes 11 species representing 9 14 Pleuronectiforme families conclude that Pleuronectoidei Psettodoidei do not form a monophyletic group, suggesting independent from different percoid ancestors. Genomic transcriptomic data indicate genes related to WNT retinoic acid pathways, hampered musculature reduced lipids might have functioned in evolution Pleuronectoidei. Evolution...
As an important freshwater aquaculture species in China, the Chinese mitten crab (Eriocheir japonica sinensis) has high economic and nutritional value. However, limited genomic information is currently available for studying its basic development genetic diversity. Here, we performed whole-genome sequencing on Oxford Nanopore Technologies Limited's platform using promethION. The assembled size of E. j.sinensis genome was approximately 1.27 Gb, which close to estimated (1.19 Gb). Furthermore,...
Abstract Endothermy is a typical convergent phenomenon which has evolved independently at least eight times in vertebrates, and of significant advantage to organisms extending their niches. However, how vertebrates other than mammals or birds, especially teleosts, achieve endothermy not previously been fully understood. In this study, we sequenced the genomes two billfishes (swordfish sailfish), members representative lineage endothermic teleosts. Convergent amino acid replacements were...
Abstract The reissner lamprey Lethenteron reissneri , belonging to the class Cyclostomata, serves as a bridge between invertebrates and jawed vertebrates, is considered sister group of vertebrates. However, despite this evolutionary significance, genetic mechanisms underlying adaptive evolution lineage remain unclear. Here, we assembled 1.06 Gb chromosome‐level draft genome L. with 72 chromosomes (ranging in length from 4.5 Mb 25.9 Mb) scaffold N50 13.23 Mb. Genome quality comparisons...
Abstract Bird sex chromosomes play a unique role in sex-determination, and affect the sexual morphology behavior of bird species. Core waterbirds, major clade birds, share common characteristics being sexually monomorphic having lower levels inter-sexual conflict, yet their chromosome evolution remains poorly understood. Here, by we analyse chromosome-level assembly female crested ibis (Nipponia nippon), typical core waterbird. We identify neo-sex resulting from fusion microchromosomes with...
The mustache toad, Vibrissaphora ailaonica, is endemic to China and belongs the Megophryidae family. Like other toad species, V. ailaonica males temporarily develop keratinized nuptial spines on their upper jaw during each breeding season, which fall off at end of season. This feature likely result reversal sexual dimorphism in body size, with being larger than females. A high-quality reference genome for would be invaluable investigate genetic mechanism underlying these repeatedly...
Gobiocypris rarus is sensitive to environmental pollution, especially heavy metal and grass carp reovirus (GCRV). Hence, it has potential utility as a biological monitor. Genetic deciphering of its unique immune system will advance our understanding adaptive strategies, which provide cues for better application. A de novo genome rare minnow was obtained, sex determination mechanism ZZ/ZW. We identified several specific mutation genes lost minnow, these might be related the sensitivity...
Abstract Background The black widow spider has both extraordinarily neurotoxic venom and three-dimensional cobwebs composed of diverse types silk. However, a high-quality reference genome for the was still unavailable, which hindered deep understanding application valuable biomass. Findings We assembled Latrodectus elegans genome, including size 1.57 Gb with contig N50 4.34 Mb scaffold 114.31 Mb. Hi-C scaffolding assigned 98.08% to 14 pseudo-chromosomes, BUSCO, completeness analysis revealed...
Genomic rearrangements are primary drivers of evolution, promoting biodiversity. Aphids, an agricultural pest with high species diversity, exhibit rapid chromosomal evolution and diverse karyotypes. These variations have been attributed to their unique holocentric chromosomes parthenogenesis, though this hypothesis has faced scrutiny. In study, we generated a chromosomal-level reference genome assembly the celery aphid (Semiaphis heraclei) conducted comparative genomic analysis, revealing...
Silk has numerous unique properties that make it a staple of textile manufacturing for several thousand years. However, wider applications silk in modern have been stalled due to limitations traditional produced by Bombyx mori. While is commonly B. mori, wild non-mulberry silkmoths--especially members family Saturniidae--produce with superior may be useful applications. Further utilization such silks hampered the non-domestication status or limited culturing population silkworms. To date...
Abstract Horseshoe crabs including Tachypleus tridentatus are a group of marine arthropods and living fossil species which have existed on the earth for ~500 million years. However, genetic mechanisms underlying their unique adaptive ability still unclear. Here, we assembled first chromosome‐level T. genome, proved that this genome is high quality with contig N50 1.69 Mb. By comparison other arthropods, some gene families experienced significant expansion, related to several signaling...
