Wound inducible P450-Esg cDNA, one of cytochrome P450 gene family, was isolated from shoot of Euiseong garlic cultivar. P450-Esg cDNA possesses highly conserved heme-binding domain in the nucleotide sequence, and 1,419 bp of open reading frame (ORF) coding of 473 amino acids. Based on the nucleotide sequence analysis of P450-Esg homologous from twelve garlic cultivars, two domains, one domain between 472 to 510 bp, and the other between 1,210 to 1,249 bp from start codon (ATG), showed various nucleotide polymorphism among cultivars. Sequence of heme-binding domain in P450-Esg homologous, which is located at the domain between 1,210 to 1,240 bp from start codon, showed various nucleotide polymorphism as well as amino acid sequence polymorphism among twelve garlic cultivars. Anther domain, between 472 to 510 bp from start codon, showed exactly same amino acid sequence in the twelve garlic cultivars, but there were various single nucleotide polymorphism to the cultivars.
