Research Project: Genetic Resources Acquisition, Conservation, International Exchange, and Taxonomic Expertise in Support of the U.S. National Plant Germplasm System **Location:
                            National Germplasm Resources Laboratory** 2023 Annual Report **Objectives**
                                

Objective 1: Support, plan, and/or conduct, in alignment with the overall NPGS Plan, international and domestic explorations and exchanges to acquire plant genetic resources, especially of crop wild relatives and landraces of major, specialty and new crops, to fill gaps in the holdings of key NPGS plant genetic resource collections. 

Objective 2. Expand the NPGS program of complementary conservation (ex situ and in situ) of crop wild relatives in the United States, in alignment with the overall NPGS Plan, through collaborations with federal, state, and private agencies.

Objective 3. Maintain GRIN Taxonomy for Plants and, in alignment with the overall NPGS Plan, expand the nomenclatural, classificatory, and geographical information available for crop wild relatives. 

Objective 4. Manage the import and export of germplasm involved in international germplasm exchanges. 

Objective 5. Serve as coordinator and secretariat for the 44 CGCs that provide technical input for NPGS plant genetic resource management plans and priorities. **Approach**
                                

Support the acquisition of plant genetic resources for the National Plant Germplasm System (NPGS), focusing on plants that fill gaps in accessions. Manage the Plant Exploration and Exchange program by updating and distributing proposal guidelines, conducting review of proposals, coordinating funding, maintaining records of explorations, verifying that accessions are submitted to the NPGS, and ensuring that accessions and associated data are documented properly in GRIN-Global. Guide scientists on proposal preparation, obtaining permissions for collecting, trip planning, documentation of collections, collecting protocols, recommended equipment, and other matters. For foreign explorations, locate national authorities for access to genetic resources per the Convention on Biological Diversity and the International Treaty on Plant Genetic Resources for Food and Agriculture. Identify appropriate benefit sharing for foreign explorations in cooperation with U.S.-based explorers, NPGS curators, collaborating foreign scientists, and national authorities on access in the host country. Expand the complementary conservation of crop wild relatives (CWR) in the United States. Identify areas in the U.S. that support significant populations of CWR. Expand collaboration to new partners, increase the numbers of CWR conserved, and provide improved access to information about CWR. Work with land managing agencies to select and designate natural areas as resource reserves for CWR. Develop an integrated conservation strategy for species of grapes (Vitis spp.) native to the United States that are important CWR of the cultivated wine grape (Vitis vinifera). Maintain and expand GRIN Taxonomy for Plants. Research changes to existing taxonomic classifications or nomenclature for possible adoption. Document all data with references in GRIN-Global. Promote the use of GRIN Taxonomy among genetic resources managers and customers by enhancing the internet search pages, encouraging user feedback, and maintaining the integrity of the scientific nomenclature. Update current and develop new crop wild relative classifications for crops based on thorough review of all pertinent taxonomic and phylogenetic literature, as well as similar review of the plant genetic, breeding, and other crop science literature. Assist scientists in complying with USDA Animal and Plant Health Inspection Service (APHIS) regulations for importing germplasm. Support the import and export of germplasm by facilitating agricultural inspections and issuances of phytosanitary certificates for NPGS genebanks. Guide NPGS curators and other staff about APHIS regulations for shipping germplasm. Serve as an interface between APHIS and the NPGS genebanks for incoming and outgoing shipments of germplasm. Coordinate and document activities for the 44 Crop Germplasm Committees (CGCs) that provide technical input for NPGS plant genetic resource management plans and priorities. Plan the annual meetings of the CGC Chairs and maintain documentation of the CGCs’ rosters, crop vulnerability statements, and other activities. Act as a liaison between CGCs and ARS leadership on issues related to plant genetic resources. **Progress Report**
                                

This report documents progress for project 8042-21000-302-000D, which started in March 2023 and continues research and service activities from its predecessor project 8042-21000-280-000D. Progress has been made on all five objectives since the new project was initiated. Under Objective 1, we supported the Plant Exploration and Exchange program by establishing agreements for approved explorations, some of which will be completed by September 30, 2023. Objective 2 focuses on developing collaborations to implement complementary conservation of crop wild relatives. Progress made towards this objective included ongoing research and conservation status assessments of Vitis species native to North America. Collaborations were made or strengthened through networking and attending meetings, including those of the Plant Conservation Alliance. Progress under Objective 3, which involves the maintenance and expansion of GRIN Taxonomy data, included adding more than 409 distribution, 1,686 literature, 34 common name, and 425 economic use records. More than 913 new taxon records were added and more than 319 were verified. More than 2,901 existing records in the taxonomy tables were also modified. Crop wild relative work in GRIN Taxonomy focused on updating and reevaluating genepool and trait data for existing crops to reflect recent research. Testing and revisions continue on the new online Taxonomy Editor interface, which will allow more efficient data entry and batch editing. For Objective 4, the export of germplasm was facilitated by ensuring that agricultural inspections were completed and phytosanitary certificates were issued within accepted timeframes. From October 2022 through June 2023, 370 public orders containing a total of 25,965 samples of NPGS accessions were shipped from Beltsville to individuals in 61 countries for research and education. Under Objective 5, we supported Crop Germplasm Committees (CGCs) by attending and reporting to CGC meetings and updating information on their committees in GRIN. **Accomplishments** **Review Publications**
