EST Data in MaizeGDB

Simple EST Search

This search form allows you to just enter basic name info to quickly retrieve the desired EST.

Use the wildcards '%' or '*' to find matches that contain your search term. '^' at the beginning of search term will find matches that start with that term. '$' at the end of search term will find matches that end with that term.

If you want to search by accession number, try the sequence search.
If you want to search by a descriptive term like dehydrogenase, also use the sequence search.
If you want to search by gene name, like bz1 or wx, try the locus search.

The above search provides an example of the type of search you can do; it returns a listing of ESTs from the 486 library of the Maize Gene Discovery Project ("std" is short for Stanford, in this case). Other interesting searches include p-std606% (the 606 library) and %606001A02% (a specific member of the 606 library).

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

Mapped ESTs: This utility displays the map locations of the ESTs in the database. You can obtain this information by chromosome (1-10, below) or all together (All, creates a very large table which will take a while to download and may cause issues with some browsers).

Our Policy on Ordering Clones

MaizeGDB does not distribute maize clones. Read on for more information about clone ordering.

If you are interested in clones that were submitted by Virginia Walbot, these clones are available at Be sure to have the GenBank record for the clone ready when you order, as you'll be required to fill in information from the record.

To find out about EST clusters/contigs, see the Sequence Data In MaizeGDB page.
