The AOP2 structural gene sequence. The sequence of the AOP2 structural gene in the Col, Ler, St, Pi and Cvi accessions is shown. The sequences from the five accessions are identical where the sequence is presented as a single line. Exons are shown in upper case letters and introns are shown in lower case letters. The sequence from the five accessions is shown separately in the regions where the three polymorphisms identified in exon 2 (5 bp, 18 bp and 9 bp) are located. Each sequencing reaction was performed three times on different PCR products to ensure accuracy of the sequence.
