Genetic diversity is a prerequisite for evolutionary change in all kinds of organisms. It generally acknowledged that populations lacking genetic variation are unable to evolve response new environmental conditions (e.g., climate change) and thus may face an increased risk extinction. Although the importance incorporating into design conservation measures now well understood, less attention has been paid distinction between neutral (NGV) adaptive (AGV) variation. In this review, we first...
Introgression may act as an important source of new genetic variation to facilitate the adaptation organisms environments, yet how introgression might enable tree species adapt higher latitudes and elevations remains unclear. Applying whole-transcriptome sequencing population analyses, we present example ancient from a cypress (
Homoploid hybrid speciation (HHS) has been increasingly recognized as occurring widely during species diversification of both plants and animals. However, previous studies on HHS have mostly focused closely-related while it rarely reported or tested between ancestors different genera. Here, we explore the likely origin Carpinus sect. Distegocarpus Ostrya in family Betulaceae. We generate a chromosome-level reference genome for C. viminea re-sequence genomes 44 individuals from genera Ostrya....
Abstract When and how disjunct distributions of biological taxa arose has long attracted interest in biogeography, yet the East Asian–Tethyan disjunction is understudied. Cupressus (Cupressaceae) shows this disjunction, with 10 species Asia three Mediterranean region. Here we used target‐capture sequencing obtained 1991 single‐copy nuclear genes, plus complete plastomes, to infer evolutionary history . Our phylogenomic reconstruction resolved four well supported clades , but revealed...
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 In the field of world heritage conservation, there has been broad consensus on carrying out conservation research basis spatial integration and interregional international cooperation. However, are still many deficiencies in culture with environment, regional economic social development, regional, holistic multimodal utilization cultural sites. China, Dongjiang-Hanjiang River Basin is a representative area substantial ecological value for both Guangdong Province whole country. This...
Abstract Gene duplication plays an important role in plants for diversification and adaptation to new habitats. In this study, we aim reconstruct the genome‐scale phylogeny identify large‐scale gene events subtribe Gentianinae (Gentianaceae), which is a great symbol of alpine Qinghai–Tibet Plateau. We sequenced assembled 70 transcriptomes from 67 species, representing all six recognized genera plus closely related outgroups. Using phylogenomic approaches, backbone relationships were almost...
The Eastern Asia (EA) - North America (NA) disjunction is a well-known biogeographic pattern of the Tertiary relict flora; however, few studies have investigated evolutionary history this using phylogenomic approach. Here, we used 2369 single copy nuclear genes and nearly full plastomes to reconstruct small genus Thuja, which consists five disjunctly distributed species. species tree strongly supported an EA clade Thuja standishii-Thuja sutchuenensis "disjunct clade", where western NA T....
Abstract Habitat loss induced by climate warming is a major threat to biodiversity, particularly threatened species. Understanding the genetic diversity and distributional responses change of species critical facilitate their conservation management. Cupressus gigantea , rare conifer found in eastern Qinghai–Tibet Plateau (QTP) at 3000–3600 m.a.s.l., famous for its largest specimen, King Cypress, which >55 m tall. Here, we obtained transcriptome data from 96 samples 10 populations...
Endangered species generally have small populations with low genetic diversity and a high load.
Abstract Natural selection serves as an important agent to drive and maintain interspecific divergence. Populus rotundifolia Griff. is alpine aspen species that mainly occurs in the Qinghai–Tibet Plateau (QTP) adjacent highlands, whereas its sister species, P. davidiana Dode, distributed across southwest central northeast China much lower altitude regions. In this study, we collected genome resequencing data of 53 42 individuals their natural distribution Our population genomic suggest two...
ABSTRACT Establishing how lineages with similar traits are phylogenetically related remains critical for understanding the origin of biodiversity on Earth. Floral in plants widely used to explore phylogenetic relationships and delineate taxonomic groups. The subtribe Swertiinae (Gentianaceae) comprises more than 350 species high floral diversity ranging from rotate tubular corollas possessing diverse nectaries. Here we performed analysis 60 all 15 genera sensu Ho Liu, representing range...
Cupressaceae is a conifer family rich in plants of horticultural importance, including Cupressus, Chamaecyparis, Juniperus, and Thuja, yet genomic surveys are lacking for this family. Cupressus gigantea, one the many rare conifers that threatened by climate change anthropogenic habitat fragmentation, plays an ever-increasing role ecotourism Tibet. To infer how past has shaped population evolution species, we generated de novo chromosome-scale genome (10.92 Gb) compared species' history...
Conifers make up about one third of global forests but are threatened by seed parasitoid wasp species. Many these wasps belong to the genus Megastigmus, yet little is known their genomic background. In this study, we provide chromosome-level genome assemblies for two oligophagous conifer species which represent first genomes genus. The assembled Megastigmus duclouxiana and M. sabinae 878.48 Mb (scaffold N50 215.60 Mb) 812.98 139.16 Mb), respectively, larger than size most hymenopterans due...
The Qinghai–Tibet Plateau (QTP) comprises a platform (sometimes called the sensu stricto), Himalayas, and Hengduan Mountains (Liang et al., 2018; Mao 2021). latter two parts adjacent highlands are also Pan-Himalaya. Numerous plants distributed there with many endemic species, probably because of high diverse landscapes created by continuous geological climatic activities (Favre 2015; As well known biodiversity hotspot alpine in world (Sun 2017), studies have been conducted on evolutionary...
Biogeographical barriers to gene flow are central plant phylogeography. In East Asia, distribution is greatly influenced by two phylogeographic breaks, the Mekong-Salween Divide and Tanaka-Kaiyong Line, however, few studies have investigated how these affect genetic diversity of species that distributed across both. Here we used 14 microsatellite loci four chloroplast DNA fragments examine patterns 49 populations Populus rotundifolia, a spans both Line in southwestern China. Demographic...
