Abstract
Enzyme activity and expression of cytochrome P450 gene involved in the pathway of capsidiol biosynthesis were compared in five different solanaceae plants such as red pepper, green pepper, tobacco, potato and egg plant. Base on genomic DNA and/or RT-PCR results, four solanaceae plants such as red pepper, green pepper, tobacco and egg plant possess P450 gene in the genome and specifically expressed by elicitor treatment. However, potato was appeared to have neither P450 nor cyclase gene in the genome. P450 genes did not show any expression in the plants under normal condition, but showed highly specific expression under elicitation condition in various organs and tissue such as leaf, root, stem and culture cells.
