Societal Impact Statement Seedbanks are vital for biodiversity conservation, but their potential remains underutilised due to a limited understanding of the intraspecific genetic diversity they hold. By leveraging digitised data associated with seedbank collections, such as sampling locations, number maternal plants and seed traits, we can attempt estimation variation identify gaps in enabling better prioritisation species conservation efforts. These advancements inform policy targets like those Kunming‐Montreal Global Biodiversity Framework, promoting more effective strategies. Digitisation emerging machine‐learning technologies offer scalable, cost‐efficient solutions enhance knowledge, ensuring resilience future generations. Summary Seedbank collections hold significant untapped advancing science practice, (i.e. within species) stored worldwide largely unknown, hindering use seeds both informing implementing situ interventions. As producing is time‐consuming expensive, other greatly our when unavailable. Information location sites, estimated population size mother from which were collected facilitate captured collections. This information also be used estimate effort required fill represent diversity, through comparison existing baselines where characterised, simulations. makes approaches above practicable at scale. In addition, digital images themselves may phenotypic can, therefore, prioritise populations studies. this article, explore made available by seedbanks improving preserved We describe possible improvements that might predictive power studies, discuss challenges opportunities these.

Опубликована: Дек. 8, 2023

In recent decades, the advent of new technologies for massive and automatized digitization, together with availability methods DNA sequencing, strongly increased interest relevance herbarium collections study plant biodiversity evolution. These approaches prompted projects aimed at creation a large dataset molecular phenological data. This review discusses challenges opportunities herbaria in context numerous national that are currently ongoing, prompting specimens understanding loss habitat shifts as consequence climate changes destruction due to human activities. With regard this, National Biodiversity Future Center (active Italy since 2022) started large-scale digitization project Herbarium Centrale Italicum Florence (Italy), which is most important Italian botanical collection, consisting more than 4 million samples present.

A Diverging Species within the Stewartia gemmata (Theaceae) Complex Revealed by RAD-Seq Data

Plants, Год журнала: 2024, Номер 13(10), С. 1296 - 1296

Опубликована: Май 8, 2024

Informed species delimitation is crucial in diverse biological fields; however, it can be problematic for complexes. Showing a peripatric distribution pattern, Stewartia gemmata and S. acutisepala (the complex) provide us with an opportunity to study boundaries among taxa undergoing nascent speciation. Here, we generated genomic data from representative individuals across the natural ranges of complex using restriction site-associated DNA sequencing (RAD-seq). Based on sequence assembled loci containing 41,436 single-nucleotide polymorphisms (SNPs) invariant sites, phylogenetic analysis suggested strong monophyly both acutisepala, latter was nested within former. Among individuals, one sampled Mt. Tianmu (Zhejiang) showed closest evolutionary affinity (which endemic southern Zhejiang). Estimated 2996 high-quality SNPs, genetic divergence between relatively low (an Fst 0.073 per-site basis). Nevertheless, observed proportion regions showing high differentiation windowed basis. Up 1037 bins value greater than 0.25, accounting 8.31% total. After SNPs subject linkage disequilibrium were pruned, principal component (PCA) that diverged along first second PCs some extent. By applying phylogenomic analysis, present determines variety diverging gemmata, providing empirical insights into speciation complex.

Herbarium specimens are increasingly being used as sources of information to understand the ecology and evolution plants their associated microbes. Most studies have a source genetic material using culture-independent approaches. We demonstrate that herbarium can also be culture nodule-associated bacteria, opening possibility plant-microbe interactions at new spatiotemporal scales. historic contemporary nodules common legume,

Phylogenomics of the pantropical Connaraceae: revised infrafamilial classification and the evolution of heterostyly

Plant Systematics and Evolution, Год журнала: 2024, Номер 310(4)

Опубликована: Авг. 1, 2024

Connaraceae is a pantropical family of about 200 species containing lianas and small trees with remarkably diverse floral polymorphisms, including distyly, tristyly, homostyly, dioecy. To date, relationships within the have not been investigated using targeted molecular phylogenetic treatment, severely limiting systematic understanding reconstruction trait evolution. Accordingly, their last infrafamilial classification was based only on morphological data. Here, we used phylogenomic data obtained Angiosperms353 nuclear target sequence capture probes, sampling all tribes almost genera, entirely from herbarium specimens, to revise investigate evolution heterostyly. The backbone resulting tree resolved. consists two clades, one African genus

Ancient Genome of Broomcorn Millet from Northwest China in Seventh Century CE: Shedding New Light to Its Origin and Dispersal Patterns

Опубликована: Сен. 2, 2024

Broomcorn millet (Panicum miliaceum) is among the earliest domesticated staple crops in world’s agricultural history and facilitated development of several early agrarian cultures, particularly those originating northern China. However, propagation route broomcorn China from Middle Ages to present remains unclear. The aim this study explore genetic affinity between ancient modern samples, trace origins diffusion pathways millet, provide insights into its domestication spread. To achieve this, we sequence DNA excavated Chashan Village cemetery (AD 691) Gansu Province, Phylogenetic population analyses, integrating genomes, reveal a close relationship contemporary Ningxia Province (445 km away Village), suggesting potential origin for millet. This finding aligns with tomb’s epitaph, which documents reburial owner, who was originally buried Ningxia, provides important archaeological evidence understanding interaction geopolitical dynamics natural environment northwest during late seventh century.
