a
PDR response element site 2 of PDR5 (13) and corresponding sequence in PDH1.
b
Palindrome with possible regulatory function (19).
c
Conserved nucleotides are shown in bold letters. A nucleotide was considered conserved if a specific base was observed at the same aligned position in more than two different genes. Gaps introduced to maximize alignment are indicated by periods.
