9
Design of GRIN molecular table schema Four new molecular tables in GRIN that Accommodate multiple marker types Provide raw allelic data for individuals Accept polyploid data Record methods and standards Impact Apple, Cacao, Grape, Hazelnut, Hops, Pea, Pear, Rhubarb and Vaccinium data are available NCBI is increasing interoperability with GRIN MARKER CROP GENETIC OBSERVATION GENOTYPIC ASSAY LIT MARKER CITATION EVALUATION INVENTORY ACCESSION
10
Sample representatively. Maintain viability and longevity. Provide annotation that authenticates, calibrates and characterizes samples. Key Metrics for genebanking
11
Data integration for genebanking Core functions involve the acquisition and maintenance of genetic variation Sample accessions are the priority. GENEBANK Plant materials Data
12
Data integration for genebanking Genomic approaches and new stakeholders. New expectations and new services that are distinctly data centered. GENEBANK Plant materials Data
13
Wild Genetic Resources GENEBANK Plant materials Data BreedingGenomics Genomic databases Ecological information

15
Wild Genetic Resources GENEBANK Plant materials Data BreedingGenomics Ecological information Genomic databases Marker assisted breeding
16
GENEBANK Plant materials Data Genomics Gene genealogies of functional loci Genetic integrity estimates Lineage identification of allele mining Spatial and environmental correlates of diversity and structure Trait specific subsets
17
Improved data integration provides tool to maintain and validate genetic diversity, provide more efficient subsets for further characterization. Integration with geo-reference and ecological data increases efficiency of locating collection sites for new accessions Impact for genebanking
18
Allele mining will benefit from collections that have information about history and structure –Partitioning of genetic clusters allows better estimation of lineages within a collection –Requires methods for SNP genotyping or targeted re-sequencing for large sets of individual samples (breadth not depth)
19
Interactions with Data Standards community –Standardized phenotyping methods-trait ontology. –Adoption of Darwin Core standards. –Development of revised habitat fields for GRIN Global.
20
Capacity building –Standardized phenotyping methods –High throughput genotyping (centralized) –Computational biology
