Abstract: Taxonomic names are critical to the communication of bio ersity—they link data together whether it be distribution data, traits or phylogeny. Large taxonomic groups, such as many plant families, are globally distributed as is the taxonomic expertise of the family. A growing knowledge base requires collaboration to develop an up-to-date checklist as a research foundation. The legume (Fabaceae) community has a strong history of collaboration including the International Legume Database and Information Service (ILDIS), which curated the names but ILDIS is no longer up to date. In 2020, under the umbrella of the Legume Phylogeny Working Group (LPWG), a group of taxonomists began updating the legume taxonomy as part of a larger collaboration around a legume data portal. Currently the World Checklist of Vascular Plants (WCVP) is the most up-to-date reference and was used as the starting point for the project. The workflow begins with over 80 volunteer taxonomic experts updating the checklist in their specialty area. These lists are manually collated, centrally creating a consensus taxonomy with synonyms. Any taxonomic conflicts are adjudicated within the group. The checklist then undergoes a comprehensive nomenclature assessment at Royal Botanic Gardens, Kew and becomes part of the WCVP. This checklist was submitted to the Catalogue of Life Checklist Bank and is integrated as the preferred legume checklist in the GBIF taxonomic backbone. After one round of taxonomic curation, 38% of the legume names in GBIF (Global Bio ersity Information Facility), which were previously unmatched to WCVP, are now connected to GBIF names, therefore also improving the occurrence records of those species. The GBIF taxonomic backbone contains names found on herbarium specimens and in the literature, which are not currently part of the legume expert community checklist or WCVP. This list of unresolved names will be forwarded to the legume community for curation, thereby developing a cycle of data improvement. It is anticipated that after a few rounds of expert curation, the WCVP and GBIF taxonomies will converge. At each cycle, a snapshot of GBIF occurrences is taken and the improvement of the occurrences is quantified to measure the value of the expert taxonomic work. The current checklist is also available via Catalogue of Life and soon via the World Flora Online to support research. In this talk, we describe the workflow and impact of the expert curated legume taxonomy.

Abstract: The need for scientists to exchange, share and organise data has resulted in a proliferation of bio ersity research-data portals over recent decades. These cyber-infrastructures have had a major impact on taxonomy and helped the discipline by allowing faster access to bibliographic information, biological and nomenclatural data, and specimen information. Several specialised portals aggregate particular data types for a large number of species, including legumes. Here, we argue that, despite access to such data-aggregation portals, a taxon-focused portal, curated by a community of researchers specialising on a particular taxonomic group and who have the interest, commitment, existing collaborative links, and knowledge necessary to ensure data quality, would be a useful resource in itself and make important contributions to more general data providers. Such an online species-information system focused on Leguminosae (Fabaceae) would serve useful functions in parallel to and different from international data-aggregation portals. We explore best practices for developing a legume-focused portal that would support data sharing, provide a better understanding of what data are available, missing, or erroneous, and, ultimately, facilitate cross-analyses and direct development of novel research. We present a history of legume-focused portals, survey existing data portals to evaluate what is available and which features are of most interest, and discuss how a legume-focused portal might be developed to respond to the needs of the legume-systematics research community and beyond. We propose taking full advantage of existing data sources, informatics tools and protocols to develop a scalable and interactive portal that will be used, contributed to, and fully supported by the legume-systematics community in the easiest manner possible.

Abstract: The immunosuppressive therapy with everolimus (ERL) after heart transplantation is characterized by a narrow therapeutic window and a substantial variability in dose requirement. Factors explaining this variability are largely unknown. Our aim was to evaluate factors affecting ERL metabolism and to identify novel metabolites associated with the in idual ERL dose requirement to elucidate mechanisms underlying ERL dose response variability. We used liquid chromatography coupled with mass spectrometry for quantification of ERL metabolites in 41 heart transplant patients and evaluated the effect of clinical and genetic factors on ERL pharmacokinetics. Non-targeted plasma metabolic profiling by ultra-performance liquid chromatography and high resolution quadrupole-time-of-flight mass spectrometry was used to identify novel metabolites associated with ERL dose requirement. The determination of ERL metabolites revealed differences in metabolite patterns that were independent from clinical or genetic factors. Whereas higher ERL dose requirement was associated with co-administration of sodium-mycophenolic acid and the CYP3A5 expressor genotype, lower dose was required for patients receiving vitamin K antagonists. Global metabolic profiling revealed several novel metabolites associated with ERL dose requirement. One of them was identified as lysophosphatidylcholine (lysoPC) (16:0/0:0). Subsequent targeted analysis revealed that high levels of several lysoPCs were significantly associated with higher ERL dose requirement. For the first time, this study describes distinct ERL metabolite patterns in heart transplant patients and detected potentially new drug-drug interactions. The global metabolic profiling facilitated the discovery of novel metabolites associated with ERL dose requirement that might represent new clinically valuable biomarkers to guide ERL therapy.
