Abstract Angiosperms represent one of the most spectacular terrestrial radiations on planet 1 , but their early diversification and phylogenetic relationships remain uncertain 2–5 . A key reason for this impasse is paucity complete genomes representing early-diverging angiosperms. Here, we present high-quality, chromosomal-level genome assemblies two aquatic species—prickly waterlily ( Euryale ferox ; Nymphaeales) rigid hornwort Ceratophyllum demersum Ceratophyllales)—and expand genomic...
Abstract Having a comprehensive understanding of population structure, genetic differentiation and demographic history is important for the conservation management threatened species. High‐throughput sequencing (HTS) provides exciting opportunities to address wide range factors genetics. Here, we generated HTS data identified 266,884 high‐quality single nucleotide polymorphisms from 82 individuals Cupressus chengiana , assess genomics across species' full range, comprising Daduhe River...
Abstract An increasing number of species are thought to have originated by homoploid hybrid speciation ( HHS ), but in only a handful cases details the process known. A previous study indicated that Picea purpurea , conifer Qinghai–Tibet Plateau QTP through from P. likiangensis and wilsonii . To investigate this origin more detail, we analysed transcriptome data for 114 individuals collected 34 populations three their core distributions Phylogenetic, principal component admixture analyses...
Nonbifurcating divergence caused by introgressive hybridization is continuously reported for groups of closely related species. In this study, we aimed to reconstruct the genome-scale classification deep lineages conifer genus Picea, establish their phylogenetic relationships and test bifurcating hypothesis between deeply branching based on genomic data. We sequenced transcriptomes 35 individuals 27 taxa covering all main genus. Four major lineages, comprising three 12 each, largely...
Urban greening provides important ecosystem services and ideal places for urban recreation is a serious consideration municipal decision-makers. Among the tree species cultivated in green spaces, Robinia pseudoacacia stands out due to its attractive flowers, fragrances, high trunks, wide adaptability, essential services. However, genomic basis consequences of wide-planting spaces remains unknown. Here, we report chromosome-level genome assembly R. pseudoacacia, revealing size 682.4 Mb 33,187...
Microbial mutualists can profoundly modify host species ecology and evolution, by extension altering interactions with other microbial species, including pathogens. Arbuscular mycorrhizal fungi (AMF) may moderate infections pathogens, but the direction strength of these effects be idiosyncratic. To assess how introduction AMF impacts incidence severity aboveground plant diseases (i.e. 'disease impact'), we conducted a meta-analysis 130 comparisons derived from 69 published studies. elucidate...
Abstract Hybridization and introgression are believed to play important roles in plant evolution. However, few empirical studies have been designed clarify the ways which these processes complicate taxonomic delimitation. Recent phylogenetic based on a number of different DNA fragments indicated that Picea brachytyla eastern Qinghai‐Tibet Plateau is polyphyletic, finding contrasts with traditional taxonomy morphological traits. We aimed test this conflict using transcriptomic data from 26...
The role of reticulation in the rapid diversification organisms is attracting greater attention evolutionary biology. Evidence genetic exchange between diverging taxa reported frequently, although most studies fail to show how hybridization and introgression contribute adaptation differentiation introgressed taxa. Here, we report a population genomics approach test evolution Picea likiangensis species complex, which comprises four occurring biodiversity hotspot Hengduan–Himalayan mountains....
Introduction Camphora longepaniculata , a crucial commercial crop and fundamental component of traditional Chinese medicine, is renowned for its abundant production volatile terpenoids. However, the lack available genomic information has hindered pertinent research efforts in past. Methods To bridge this gap, present study aimed to use PacBio HiFi, short-read, highthroughput chromosome conformation capture sequencing construct chromosome-level assembly C. genome. Results discussion With...
Extinct taxa may be detectable if they were ancestors to extant hybrid species, which retain their genetic signature. In this study, we combined phylogenomics, population genetics and fluorescence in situ hybridization (GISH FISH) analyses trace the origin of alpine tetraploid Allium tetraploideum (2n = 4x 32), one five known members subgenus Cyathophora. We found that A. was an obvious allotetrapoploid derived from including at least two closely related diploid farreri cyathophorum, it...
Abstract The genetic bases of halophytes for salinity tolerance are crucial genetically breeding salt-tolerant crops. All natural Nitrariaceae species that exclusively occur in arid environments highly tolerant to salt stress, but the underlying genomic this adaptation remain unknown. Here we present a high-quality, chromosome-level genome sequence Nitraria sibirica, with an assembled size 456.66 Mb and 23,365 annotated genes. Phylogenomic analyses confirmed N. sibirica as sister all other...
Speciation among populations connected by gene flow is driven adaptation to different environments, but underlying gene-environment associations remain largely unknown. Here, 162 individuals from 32 were sampled obtain 191,648 independent single nucleotide polymorphisms (SNPs) across the genomes of two closely related spruce species, Picea asperata and crassifolia, which occur on Qinghai-Tibet Plateau in surrounding regions. Using SNP data set, genotype-environment demographic modelling used...
Abstract Radiation rather than bifurcating divergence has been inferred through a number of phylogenetic analyses using different DNA fragments. However, such inferences have rarely tested by examining alternative hypotheses based on population genomic data. In this study, we sequenced the transcriptomes 32 individuals from 13 populations four Orychophragmus spp. (Brassicaceae) to investigate their history. Cluster and structure recovered distinct genetic clusters without any mixture. Most...
Abstract Lepus oiostolus ( L . ) is a species endemic to the Qinghai-Tibet Plateau. However, absence of reference genome limits genetic studies. Here, we reported high-quality assembly, with scaffolds anchored 24 chromosomes and total assembled length 2.80 Gb (contig N50 = 64.25 Mb). Genomic annotation uncovered 22,295 protein-coding genes identified 49.84% sequences as transposable elements. Long interspersed nuclear elements (LINEs) constitute high proportion genome. Our study at first...
• The study delves into the intricate evolutionary patterns within extended Picea likiangensis species complex (e-PLSC), uncovering significant incongruity between chloroplast and nuclear trees. discordance is attributed to introgression (54.99%) incomplete lineage sorting (ILS; 33.12%). Recombination rates played a pivotal role in shaping introgression, with regions of high recombination exhibiting elevated levels both ILS introgression. Genes implicated high-level are found be associated...

Parallel evolution of reproductive isolation (PERI) provides strong evidence for natural selection playing a fundamental role in the origin species. However, PERI has been rarely demonstrated well established species drawn from different genera. In particular, parallel molecular signatures same genes response to similar habitat divergence such lineages is lacking. Here, based on whole-genome sequencing data, we first explore speciation process two sister Carpinus (Betulaceae) temperature and...
