Sequence retrieval

There are several possible starting points for using a database to find more information:

You may have a DNA sequence of your own (perhaps you have sequenced a PCR product from your research).

1) You may be interested in a particular sequence, for example one that you saw in a publication or online.

2) You may be interested in sequences that relate to a specific function, for example "drought tolerance".

Most databases allow you to search in any of these ways. Below is an example from Gramene (http://www.gramene.org/ ).
