Project Type: In-House Appropriated

Start Date: Apr 11, 2008

Identify key germplasm gaps in NPGS collections, prioritize the acquisition needs, identify opportunities for acquisition, and secure needed genetic resources through cross-institutional linkages, plant exchanges, explorations, and importation. Develop approaches to share benefits with host countries for providing NPGS access to needed germplasm. Expand, enhance, and maintain the online database (GRIN-Taxonomy)that provides access to, and promotes the proper and consistent use of validated, standard botanical and cultivated scientific plant names, taxonomic classifications, and associated data by genetic resource managers and researchers worldwide. Expand the nomenclatural, classificatory, and ecogeographical information available on GRIN for highly diverse specialty crop taxa.

To identify NPGS germplasm gaps, we will assemble and analyze systematic and ecogeographic data on the taxa in the crop genepool, current ex situ holdings of germplasm of taxa in the crop genepool, reported problems in the crop that can be addressed by additional germplasm, reported needs of breeders or other researchers for new germplasm and in situ conservation status of taxa in the genepool genetic resources. Maintain all of the identified NPGS germplasm gaps in a searchable database. Prioritize the identified collection needs to acquire the more valuable and most threatened accessible genetic resources that are needed. Priority factors include: interest of the curator and CGC in acquiring new germplasm, potential of the target germplasm to solve the identified problem(s) in the crop, magnitude of the identified gaps in the NPGS, accessibility to germplasm in countries within the distribution of the taxa in the genepool, and the projected economic value of use of the targeted germplasm. Administer the Plant Exploration and Exchange Program to obtain the needed germplasm. Monitor the latest taxonomic literature, through routine literature searches to detect any changes to existing taxonomy and/or nomenclature for possible adoption in GRIN. Correct authorship and spelling or other details of publication of a name to ensure the accuracy of this information. Conform all nomenclature to the International Code of Botanical Nomenclature (ICBN). Cite in GRIN the literature or other bases for taxonomic or nomenclatural decisions. New classifications based on molecular evidence, will be considered for GRIN taxonomy provided that they conform to acceptable nomenclature in ICBN. Synonyms accepted in recent literature will be added. Common names in French, German, Portuguese, Spanish, Chinese, or Japanese, will be added in conformity to GRIN standards and reflecting native scripts when possible. The sources for all common names, the negative economic effects of alternate host plants for plant diseases or pests, and of weeds and poisonous plants will be recorded on GRIN. Native distributions will be documented by country (or state for large countries) and these records linked to more detailed external web resources. Information on non-native distributions will also be provided, and for invasive or potentially invasive species distribution data will be evaluated in comparison to data from federal and state invasive species initiatives.
