Molecular Diversity Search

Please select the database of your interest first.

From this search utility you can download information about all the markers used for the crop of your interest, including name of the marker, name of the gene/locus, and type of the marker, as well as primer sequences and repeated element for SSR markers (for maize and wheat). Please read this help document for how to obtain details of the markers assayed for rice.

To obtain a complete list of the markers in a database, leave all the search parameters in their default state, choose the output format you would like, and click Submit. To change the sorting order of the resulting output, modify the 'Sort by' parameters before clicking Submit. To limit the search by marker name, gene/locus name or marker type, use the text input fields to specify the marker name or gene/locus name, or the drop-down menu to specify the marker type.

The text input fields (Marker and Gene/Locus) are set by default for an exact match ('equals'). The search can be modified to find marker or gene/locus names either containing the text that you enter ('contains') or matching the text/wildcard combination that you enter ('matches'). The wildcard '?' stands for a single character while '*' stands for zero or more characters. The search is not case-sensitive.

Output tables in HTML format will appear below the search form on a refreshed page. To see the genotypes (or sequence alignments) corresponding to a marker, follow the link (displaying the marker type) in the Assays column of the HTML output table. The complete results of your molecular diversity search can also be downloaded and saved in Excel format or in one of three different text formats: fixed-width, comma-separated or tab-delimited.
