Please select the database of your interest first.

From this search utility you can download information about all the loci assayed for the crop of your interest, including name and type of the loci. For the maize loci, you can also view their location within the maize genome. To obtain this information, use the search form at the right. To obtain a complete list of the loci from 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 prior to clicking Submit.

To limit the search by your criteria of interest, use the drop-down menus and text boxes to specify your criteria. Types of loci include Mapped, Unmapped, and cytological loci. If you wish, the search can be confined to only those genes or loci for which at least one assay was performed for a marker of a given type (SSRs, SNPs, Sequencing, etc). However, the other marker types present in the resulting loci will also be listed. In addition, the search can be confined to a particular chromosomal region, relative to the IBM2 2004 Neighbors genetic map.

The text input field (Gene/Locus) is set by default for an exact match ('equals'). The search can be modified to find 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. Alternatively, the complete results of your search can be downloaded and saved in Excel format or in one of three different text formats: fixed-width, comma-separated or tab-delimited.
