Abundant and plentiful fruit crops are threatened by the loss of diverse legacy cultivars which being replaced a limited set high-yielding ones. This article delves into potential paleogenomics that utilizes ancient DNA analysis to revive lost diversity. By focusing on grapevines, date palms, tomatoes, recent studies showcase effectiveness paleogenomic techniques in identifying understanding genetic traits crucial for crop resilience, disease resistance, nutritional value. The approach not only tracks landrace dispersal introgression but also sheds light domestication events. In face major future environmental challenges, integrating with modern breeding strategies emerges as promising avenue significantly bolster sustainability.

Abstract Dissecting plant responses to the environment is key understanding whether and how plants adapt anthropogenic climate change. Stomata, plants’ pores for gas exchange, are expected decrease in density following increased CO 2 concentrations, a trend already observed multiple species. However, it unclear such based on genetic changes evolutionary adaptation. Here we make use of extensive knowledge 43 genes stomatal development pathway newly generated genome information 191 Arabidopsis thaliana historical herbarium specimens collected over 193 years directly link variation with While find that essential transcription factors SPCH, MUTE FAMA, central development, under strong constraints, several regulators show signs local adaptation contemporary samples from different geographic regions. We then develop functional score known effects gene knock-out recovers classic pattern past centuries, suggesting component contributing this This approach combining genomics experimental could allow further investigations different, even unmeasurable, cellular phenotypes may have responded change through adaptive evolution.

Abstract Global patterns of population genetic variation through time offer a window into evolutionary processes that maintain diversity. Over time, lineages may expand or contract their distribution, causing turnover in composition. At individual loci, migration, drift, environmental change (among other processes) affect allele frequencies. Museum specimens widely distributed species unique the genetics understudied populations and changes over time. Here, we sequenced genomes 130 herbarium 91 new field collections Arabidopsis thaliana combined these with published genomes. We sought broader view genomic diversity across species, to test if composition is changing documented extensive previously uncharacterized range Africa, are under threat from anthropogenic climate change. Through did not find dramatic populations.

The use of herbaria for science and conservation is revolutionizing the discovery, exploration, protection biodiversity at unprecedented scopes scales. Global Metaherbarium—a digitally interlinked, open-access resource—is stimulating these efforts helping to facilitate massive investigations that utilize aggregated digital derivatives physical herbarium specimens. Simultaneously, growing this virtual resource expanding collections by researchers from many scholarly domains who increasingly are sampling specimens multiomic (e.g., genomics, transcriptomics, metabolomics, proteomics, microbiomics). These leading new scientific insights supporting development actions, but they come with a substantial cost: (partial) destruction priceless often irreplaceable specimens, which constitute global heritage should be permanently safeguarded future reference. absence comprehensive set “best practices” destructively leads confusion uncertainty institutions alike risks over-exploitation precious when research executed. Here, we provide best practices aimed reducing uncertainties creating framework sustainably ethically Our recommendations intended two complementary overlapping audiences—users stewards—who together build, use, protect collections.

Societal Impact Statement Biological samples and their associated information are an essential resource used by scientists, governments, policymakers, practitioners communities to ensure that biodiversity can be appropriately protected sustainably used. Yet, considering the enormous task of documenting vast numbers as‐yet‐unknown plant fungal species, greater international coordination for biological collecting recording is necessary, built on equitable practices standards. Here, we propose five commitments accelerate enhance scientific knowledge diversity, while increasing collaboration, benefit sharing efficiency. Summary Almost all life depends plants fungi, making diversity distribution—primarily derived from collections—fundamental national conservation, restoration sustainable use commitments. However, it estimated some 15% species over 90% have not yet been scientifically described, hampering our ability assess demonstrate impact efforts halt loss. In addition, organisations researchers around world lack a concerted strategy complementarity avoiding overlap in botanical mycological research, particularly relation collection specimens. We here present 2030 Declaration Scientific Plant Fungal Collecting, summarising commitment towards such necessary strategy. Its components were identified discussions during after series four workshops plenary at 2023 State World's Plants Fungi symposium convened Royal Botanic Gardens, Kew, then consolidated into form authors. The was subsequently opened up endorsement signatories. Collectively, agree set cataloguing world's flora funga, designed maximise efficiency, facilitate exchange promote collaborations: (1) evidence‐based strategies; (2) strengthen local capacity; (3) collaborate across taxa disciplines; (4) collect future; (5) share benefits. This first step increased global regional efforts.
