| Outline of Final Research Achievements |
1) Genes for biosynthetic enzymes, especially novel cytochrome P450 and O-methyltransferases, and transcription factors in isoquinoline alkaloid (IQA) biosynthesis were identified based on the draft genome sequence and trascriptome analysis of Eschscholzia californica. 2) Post-transcriptional regulation of WRKY transcription factor in Coptis japonica were characterized for the stable metabolite production. 3) Transcriptomes were characterized in several IQA producing plants to isolate IQA biosynthetic enzyme genes. 4) Common origin of methylenedioxy ring degradation and demethylation enzyme was identified in bacteria. 5) For the microbial production of useful IQAs, total biosynthesis of opiates by stepwise fermentation was established in engineered Escherichia coli, beside the efficient microbial production of stylopine using a Pichia pastoris expression system. 6) 13-Methylberberine, a berberine analogue with stronger anti-adipogenic effects on mouse 3T3-L1 cells was identified.
