NCBI BLAST
Please choose the Gene Chip Sequence. You can either choose one
from the drop down list or enter one in the text box. If both are
chosen, the text box input will have priority over the drop down list. If the input is of the format of Barley1_xxxx, the real sequence will be used for blast instead of probeset name. You can still enter accession number in the textbox.

BLAST Program:
Program  Description
blastp Compares an amino acid query sequence against a protein sequence database.
blastn Compares a nucleotide query sequence against a nucleotide sequence database.
blastx Compares a nucleotide query sequence translated in all reading frames against a protein sequence database. You could use this option to find potential translation products of an unknown nucleotide sequence.
tblastn Compares a protein query sequence against a nucleotide sequence database dynamically translated in all reading frames.
tblastx Compares the six-frame translations of a nucleotide query sequence against the six-frame translations of a nucleotide sequence database. Please note that the tblastx program cannot be used with the nr database on the BLAST Web page because it is computationally intensive.
