Abstract Under the recently adopted Kunming‐Montreal Global Biodiversity Framework, 196 Parties committed to reporting status of genetic diversity for all species. To facilitate reporting, three indicators were developed, two which focus on processes contributing conservation: maintaining genetically distinct populations and ensuring are large enough maintain diversity. The major advantage these is that they can be estimated with or without DNA‐based data. However, demonstrating their...
The evolutionary timescale of angiosperms has long been a key question in biology. Molecular estimates this have shown considerable variation, being influenced by differences taxon sampling, gene fossil calibrations, models, and choices priors. Here, we analyze data set comprising 76 protein-coding genes from the chloroplast genomes 195 taxa spanning 86 families, including novel genome sequences for 11 taxa, to evaluate impact priors, sampling on Bayesian angiosperm timescale. Using relaxed...
With high quantity and quality data production low cost, next generation sequencing has the potential to provide new opportunities for plant phylogeographic studies on single multiple species. Here we present an approach in silicio chloroplast DNA assembly nucleotide polymorphism detection from short-read shotgun sequencing. The is simple effective can be implemented using standard bioinformatic tools. genome of Toona ciliata (Meliaceae), 159,514 base pairs long, was assembled Illumina...
Genetic variation for pathogen infectivity is an important driver of disease incidence and prevalence in both natural managed systems. Here, we use the interaction between rust pathogen, Melampsora lini, two host plants, Linum marginale usitatissimum, to examine how host–pathogen interactions influence maintenance polymorphism genes underlying virulence. Extensive sequence at effector loci (AvrP123, AvrP4) was found M. lini isolates collected from across native range L. Australia, as well a...
Here we present “Restore and Renew,” a replicable framework for gathering interpreting evolutionary, ecological, genomic data in support of restoration practices. In an era rapid climatic change continuous widespread clearing, revegetation projects need to focus on producing resilient long‐term self‐sustaining populations. Restore Renew expands current knowledge genetic provenance via genome‐scan data, environmental niche modeling (ENM), site‐specific climate information. The sampling...
Telopea speciosissima, the New South Wales waratah, is an Australian endemic woody shrub in family Proteaceae. Waratahs have great potential as a model clade to better understand processes of speciation, introgression and adaptation, are significant from horticultural perspective. Here, we report first chromosome-level genome for T. speciosissima. Combining Oxford Nanopore long-reads, 10x Genomics Chromium linked-reads Hi-C data, assembly spans 823 Mb (scaffold N50 69.0 Mb) with 97.8%...
Seed banks are a vital resource for preserving plant species diversity globally. However, seedling establishment and survival rates from banked seeds can be poor. Despite growing appreciation the role of seed-associated microbiota in supporting seed quality health, our understanding effects conventional banking processes on microbiomes remains limited. In this study we investigated composition functional potential bacterial epiphytes associated with stored freshly collected native plant,...
Abstract Local adaptation is the biological process by which native populations become more fit. Intraspecific patterns of local occur through shifts in allele frequency within or near genes and may similarly across species. Identifying repeated species increases statistical power to determine causal driving reveals insights into nature evolution. These types could have theoretical applied applications, particularly as climate continues change. We interrogate molecular 13 eucalypt In total,...
Generalized guidance such as “local is best” has prevailed regarding seed sourcing strategies for ecological restoration in the past. A shift currently underway this guidance, moving toward using pre‐adapted material face of human induced climate change and species‐specific to maximize success self‐sustainability plantings. Meanwhile, population‐level genetic data proving an increasingly valuable tool achieve this, providing biologists insights into evolutionary history processes that impact...
Juniperus communis is a dioecious, wind pollinated shrub or small tree that produces 'berries' (female cones) containing number of seeds are thought to be dispersed by birds. The expectation, therefore, would populations Juniper genetically diverse with little structuring between them. In Britain, the species has two main centres distribution: highland zone in north and west, which still large sexually reproducing, southern on chalk downlands fragmented individuals suffer from decline...
Standardized phylogeographic studies across codistributed taxa can identify important refugia and biogeographic barriers, potentially uncover how changes in adaptive constraints through space time impact on the distribution of genetic diversity. The combination next-generation sequencing methodologies that enable uncomplicated analysis full chloroplast genome may provide an invaluable resource for such studies. Here, we assess potential a shotgun-based method twelve nonmodel rainforest trees...
Abstract Aim We take advantage of next generation sequencing‐based technology to assess how landscape‐level dynamics, biogeographical history and functional factors shape the distribution genetic diversity in rain forest trees. To achieve this, we explore chloroplast genomic divergence patterns across multiple, co‐distributed species from three major centres diversity. Location Subtropical forests south‐eastern Australia: Nightcap–Border Ranges, Dorrigo Washpool. Methods assembled data...
The Wollemi pine (Wollemia nobilis) is a rare Southern conifer with striking morphological similarity to fossil pines. A small population of W. nobilis was discovered in 1994 remote canyon system the National Park (near Sydney, Australia). This contains fewer than 100 individuals and critically endangered. Previous genetic studies have investigated its evolutionary relationship other pines family Araucariaceae, suggested that genome little or no variation. However, these were performed prior...
Pathogen genes involved in interactions with their plant hosts are expected to evolve under positive Darwinian selection or balancing selection. In this study a single copy avirulence gene, AvrP4 , the pathogen Melampsora lini was used investigate evolution of such gene across species. Partial translation elongation factor 1-alpha sequences were obtained establish phylogenetic relationships among We amplified homologues from species pathogenic on different families and orders, inferred...
In Arabidopsis (Arabidopsis thaliana), small gene families encode multiple isoforms for many of the components mitochondrial protein import apparatus. There are three TRANSLOCASE OF THE INNER MEMBRANE17 (Tim17). Transcriptome analysis indicates that AtTim17-1 is only detectable in dry seed. this study, two independent transfer DNA insertional mutant lines tim17-1 exhibited a germination-specific phenotype, showing significant increase rate germination. Microarray analyses revealed Attim17-1...
Abstract Understanding the role of climate changes and geography as drivers population divergence speciation is a long‐standing goal evolutionary biology can inform conservation. In this study, we used restriction site‐associated DNA sequencing (RAD‐seq) to evaluate genetic diversity, structure, infer demographic history endangered tree, Phoebe zhennan which distributed around Sichuan Basin. Genomic patterns revealed two distinct clusters, each largely confined West East. Despite sympatry...
Abstract Translocation is an important conservation tool for reducing the probability of extinction threatened plants. It also becoming increasingly common management practice, as habitats are destroyed and climate change pushes more plants beyond limits their tolerances. Here we outline case informing translocations with dedicated genomic data. We begin by describing principles using genetic approaches to enhance efficiency success translocation actions. This includes ensuring that...
• Although founder populations often have low diversity, they can potentially serve as stepping stones for further colonization, refugia during nonoptimal times and a source of specialized adaptive potential. The demonstration such potential within natural plant has proven to be particularly difficult. Our investigation into geographically disjunct population heterostylous shrub, Erythroxylum pusillum, aims explore the evolutionary ecological consequences being an isolated population....
