aThere was no significant similarity between the BBF sequence and the Arabidopsis class 1 or class 3 genes.
bThe total score of an alignment is calculated as the sum of substitution and gap scores.
cThe percentage of query residues that align with the subject residues.
dThe Expect value represents the number of different alignments that is expected to occur in a database search by chance. Value of 0 means the expect value was less than e-179.
eThe extent to which two amino acid sequences have the same residues at the same positions in an alignment.
