Whole-genome duplications(WGDs)are an important contributor to phenotypic innovations in evolutionary history.The diversity of blood oxygen transport traits is the perfect reflection of physiological versatility for evolutionary success among vertebrates.In this study,the evolutionary changes of hemoglobin(Hb)repertoire driven by the recent genome duplications were detected in representative Cyprinidae fish,including eight diploid and four tetraploid species.Comparative genomic analysis revealed a substantial variation in both membership composition and intragenomic organization of Hb genes in these species.Phylogenetic reconstruction analyses were conducted to characterize the evolutionary history of these genes.Data were integrated with the expression profiles of the genes during ontogeny.Our results indicated that genome duplications facilitated the phenotypic diversity of the Hb gene family;each was associated with species-specific changes in gene content via gene loss and fusion after genome duplications.This led to repeated evolutionary transitions in the ontogenic regulation of Hb gene expression.Our results revealed that genome duplications helped to generate phenotypic changes in Cyprinidae Hb systems.

Two-dimensional material has been widely investigated for potential applications in sensor and flexible electronics.In this work,a self-powered flexible humidity sensing device based on poly(vinyl alcohol)/Ti_(3)C_(2)Tx(PVA/MXene)nanofibers film and monolayer molybdenum diselenide(MoSe2)piezoelectric nanogenerator(PENG)was reported for the first time.The monolayer MoSe_(2)-based PENG was fabricated by atmospheric pressure chemical vapor deposition techniques,which can generate a peak output of 35 mV and a power density of42 mW m^(-2).The flexible PENG integrated on polyethylene terephthalate(PET)substrate can harvest energy generated by different parts of human body and exhibit great application prospects in wearable devices.The electrospinned PVA/MXene nanofiber-based humidity sensor with flexible PET substrate under the driven of monolayer MoSe_(2) PENG,shows high response of~40,fast response/recovery time of 0.9/6.3 s,low hysteresis of 1.8%and excellent repeatability.The self-powered flexible humidity sensor yields the capability of detecting human skin moisture and ambient humidity.This work provides a pathway to explore the high-performance humidity sensor integrated with PENG for the self-powered flexible electronic devices.

Major historical events often trigger the rapid flourishing of a few lineages,which in turn shape established biodiversity patterns.How did this process occur and develop?This study provides a window into this issue.The endemic East Asian carps(EEAC)dominated the ichthyofauna of East Asia and exhibited a high degree of adaptation to monsoonal river-lake ecosystems.A series of evidence,including ecogeography,phylogenetics,and macroevolution,suggests that the EEAC is a lineage that arose with the East Asian monsoon and thrived intimately with subsequent monsoon activities.We further deduce the evolution of the EEAC and find that a range of historical events in the monsoon setting(e.g.,marine transgression and regression and glacial-interglacial cycle)have further reshaped the distribution patterns of EEAC’s members.Comparative genomics analyses reveal that introgressions during the initial period of EEAC radiation and innovations in the regulation of the brain and nervous system may have aided their adaptation to river-lake ecosystems in a monsoon setting,which boosted radiation.Overall,this study strengthens knowledge of the evolutionary patterns of freshwater fishes in East Asia and provides a model case for understanding the impact of major historical events on the evolution of biota.

Developing high efficient bifunctional oxygen electrocatalysts for clean energy applications like Zin-air battery(ZAB)is highly desired,because it would reduce the cost and speed up the practical application of ZAB.Here we use a dual metal-organic framework(MOF)synthesis strategy to prepare the N-doped carbon supported bimetallic FeCo nanoparticle catalysts(marked as FeCo@NC)by pyrolysis of Zn CoZIF/MIL-101(Fe)composite.The FeCo@NC exhibits remarkable electrocatalytic activity for ORR with half-wave potential of 0.89 V vs.the reversible hydrogen electrode(RHE)and robust durability for both ORR and OER(oxygen reduction reaction and oxygen evolution reaction),which is attributed to the generation of Fe_(0.26)Co_(0.74) crystalline phase and mesopores due to the dual-MOF synthesis strategy.The rechargeable ZAB based on FeCo@NC air electrode shows a maximum energy density of139.6 mW·cm^(-2) and excellent cyclic stability over 130 h,significantly surpassing the Pt and Ir-based ZAB.The present work provides a useful dual-MOF synthesis strategy for preparing high-performance multifunctional catalysts for ORR,OER and hydrogen evolution reaction(HER).

Dear Editor,The coexistence of various species in a shared natural environment often results in the differentiation of their ecological niches, as they adapt to specific ecological roles(Jani?ová et al., 2018), this process leads to the development of distinct phenotypic traits and dietary preferences(Li et al., 2021). Studying this adaptive evolution, the four major Asian domestic carps, namely Ctenopharyngodon idella(grass carp), Mylopharyngodon piceus(black carp),

The uplift of the Tibetan Plateau significantly altered the geomorphology and climate of the Euroasia by creating large mountains and rivers.Fishes are more likely to be affected relative to other organisms,as they are largely restricted to river systems.Faced with the rapidly flowing water in the Tibetan Plateau,a group of catfish has evolved greatly enlarged pectoral fins with more numbers of fin-rays to form an adhesive apparatus.However,the genetic basis of these adaptations in Tibetan catfishes remains elusive.In this study,we performed comparative genomic analyses based on the chromosome-level genome of Glyptosternum maculatum in family Sisoridae and detected some proteins with conspicuously high evolutionary rates in particular in genes involved in skeleton development,energy metabolism,and hypoxia response.We found that the hoxd12a gene evolved faster and a loss-of-function assay of hoxd12a supports a potential role for this gene in shaping the enlarged fins of these Tibetan catfishes.Other genes with amino acid replacements and signatures of positive selection included proteins involved in low temperature(TRMU)and hypoxia(VHL)responses.Functional assays reveal that the G.maculatum TRMU allele generates more mitochondrial ATP than the ancestral allele found in low-altitude fishes.Functional assays of VHL alleles suggest that the G.maculatum allele has lower transactivation activity than the low-altitude forms.These findings provide a window into the genomic underpinnings of physiological adaptations that permit G.maculatum to survive in the harsh environment of the Tibetan Himalayas that mirror those that are convergently found in other vertebrates such as humans.

Apparent cases of sympatric speciation may actually be due to micro-allopatric or micro-parapatric speciation.One way to distinguish between these models is to examine the existence and nature of genomic islands of divergence,wherein divergent DNA segments are interspersed with low-divergence segments.Such islands should be rare or absent under micro-allopatric speciation but common in cases of speciation with gene flow.Sympatric divergence of endemic fishes is known from isolated saline,crater,postglacial,and ancient lakes.Two morphologically distinct cyprinid fishes,Gymnocypris eckloni scoliostomus(GS) and G.eckloni eckloni(GE),in a small glacial lake on the Qinghai-Tibet Plateau,Lake Sunmcuo,match the biogeographic criteria of sympatric speciation.In this study,we examined genome-wide variation in 46individuals from these two groups.The divergence time between the GS and GE lineages was estimated to be 20-60 Kya.We identified 54 large genomic islands(≥100 kb) of speciation,which accounted for 89.4%of the total length of all genomic islands.These islands harboured divergent genes related to olfactory receptors and olfaction signals that may play important roles in food selection and assortative mating in fishes.Although the genomic islands clearly indicated speciation with gene flow and rejected micro-allopatric speciation,they were too large to support the hypothesis of sympatric speciation.Theoretical and recent empirical studies suggested that continual gene flow in sympatry should give rise to many small genomic islands(as small as a few kilobases in size).Thus,the observed pattern is consistent with the extensive evidence on parapatric speciation,in which adjacent habitats facilitate divergent selection but also permit gene flow during speciation.We suggest that many,if not most,of the reported cases of sympatric speciation are likely to be micro-parapatric speciation.
