Sequence-indexed data search

Search by Sequence is no longer updated due to resource constraints. We recommend using BLAST instead.
Search for one or more specific types of information associated with a sequence. You can learn more here. Queries can contain up to 5 sequences of up to 10,000 total length. If the data types you are looking for aren't provided in the form below, try POPcorn BLAST.

Some types of searches may take several minutes to complete.

Step 1: input your sequences (Raw, FASTA, Genbank accessions, or GRMZM ids)

Overview of BLAST

Basic Local Alignment Search Tool, or BLAST, is an algorithm for comparing similarity in biological sequences. It operates on such sequences as the sequence of amino acids in proteins or the sequence of nucleotides of DNA or RNA molecules.
