KNApSAcK family databases: integrated metabolite-plant species databases for multifaceted plant research.
A search engine within the KNApSAcK Core DB is developed, making it possible to search for metabolites based on an accurate mass, molecular formula, metabolite name or mass spectra in several ionization modes, and databases for retrieving metabolites related to plants used for a range of purposes are developed.
Direct evidence for anthocyanidin synthase as a 2-oxoglutarate-dependent oxygenase: molecular cloning and functional expression of cDNA from a red forma of Perilla frutescens.
It is shown that anthocyanidins are formed in vitro through 2-oxoglutarate-dependent oxidation of leucoanthocyanIDins catalyzed by the recombinant ANS and subsequent acid treatment.
Novel detoxification of the trichothecene mycotoxin deoxynivalenol by a soil bacterium isolated by enrichment culture
Strain E3-39 was classified as a bacterium belonging to the Agrobacterium-Rhizobium group, indicating that the 3-OH group in deoxynivalenol is likely to be involved in exerting its immunosuppressive toxicity.

The cloning and characterization of cDNAs encoding strictosidine synthase and tryptophan decarboxylase are described, two key enzymes in the biosynthesis of TIA from hairy roots of O. pumila that are presumed to be indirectly involved in camptothecin synthesis.
Two glycosyltransferases involved in anthocyanin modification delineated by transcriptome independent component analysis in Arabidopsis thaliana
Two glycosyltransferases, UGT79B1 and UGT84A2, found to cluster with anthocyanin biosynthetic genes, suggest major routes from cyanid in 3-O-glucoside to the most highly modified cyanidin in the potential intricate anthokyanin modification pathways in Arabidopsis.
