Technical Abstract: MaizeGDB has several ways to archive trait data used for QTL and GWAS analyses. The simplest is simple posting of files provided by researchers along with links to the publication. More recently we have begun to integrate these data for diversity recombinant germplasm, and association panels. The goal is to integrate these data at one location, so that they may be used with minimal processing by researchers. Access to the data is provided under the ‘Diversity’ button on the home page, and, new this year, on individual Stock and Trait pages. For germplasm distributed by the North Central Regional Plant Introduction Station, individual Stock records link to the corresponding GRIN record, from which the germplasm may be requested. Last year our focus was on NAM and IBM mapping population, where we added values for some 60 traits. this year we have integrated published data for two diversity panels: the expanded Goodman panel, (Flint-Garcia et al 2005 Plant J 44:1054-64); and the Ames panel (Romay et al 2013 Genome Biol 14:R55) for many of the same traits. Additional trait categories this year include root architecture; disease response; and shoot apical meristem architecture. All traits are linked to controlled vocabularies, notably trait ontology, and the plant ontology (anatomy, growth), which permit filtering datasets, e.g. all ear traits; and promote interoperability with other crop and model plant species data.
