Simple Map Search

Handy reference for determining what are the most current maps and for understanding the content of the various Neighbors maps.

If you are looking for particular map markers, use the locus search.

This search form allows you to just enter a name or partial name to quickly retrieve the desired map.

(see a sample map query)

    (upper limit on results is 2,000 records)

Other interesting searches include Genetic (locates our genetic maps) and SSR (finds maps assembled using SSRs)

This search can be executed on every page on the site by utilizing the form in the upper right corner. Choose "map" from the drop-down menu, enter your search term in the field, and hit return to find the map you're looking for.

Set Up Search Criteria

Check the boxes next to the fields you want to search; by setting a criterion, the box will be checked for you. Only checked boxes will have that criterion evaluated.

Map Reports & Tools

Composite Genotype Finder: This tool allows you to search for particular genotypes at loci of interest, browse genotype data from different genetic maps, and obtain stocks that have desired genotypes.

Incongruencies between B73 RefGen_v2 and ISU Integrated IBM 2009 map : This tool lists loci that are placed on B73 RefGen_v2 by sequence similarity (via BLAST),and compares that position to their predicted genomic position based on their genetic position on the ISU Integrated IBM 2009 map.
