Functional genomics by integrated analysis of metabolome and transcriptome of Arabidopsis plants over-expressing an MYB transcription factor.
The functional genomics approach through the integration of metabolomics and transcriptomics presented here provides an innovative means of identifying novel gene functions involved in plant metabolism. Expand
The flavonoid biosynthetic pathway in Arabidopsis: structural and genetic diversity.
This review describes the state-of-art of flavonoid biosynthetic pathway in Arabidopsis regarding both structural and genetic diversity, focusing on the genes encoding enzymes for the biosynthesis reactions and vacuole translocation. Expand
Enhancement of oxidative and drought tolerance in Arabidopsis by overaccumulation of antioxidant flavonoids
Antioxidative activity assays showed that anthocyanin overaccumulation with strong in vitro antioxidative activity mitigated the accumulation of reactive oxygen species in vivo under oxidative and drought stress, confirming the usefulness of flavonoids for enhancing both biotic and abiotic stress tolerance in crops.

Regulation of sulfur assimilation in higher plants: a sulfate transporter induced in sulfate-starved roots plays a central role in Arabidopsis thaliana.
The sulfate transporter (AST68) exhibited the most intensive and specific response in roots, indicating that AST68 plays a central role in the regulation of sulfate assimilation in plants. Expand
Recent advances in the biosynthesis and accumulation of anthocyanins.
This review describes biochemistry, molecular biology and regulation of anthocyanin biosynthesis, with particular emphasis on mechanistic features and late steps of anthocyanin biosynthesis includingExpand
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. Expand
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. Expand
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. Expand
A WD-repeat-containing putative regulatory protein in anthocyanin biosynthesis in Perilla frutescens
A model of genetic regulation in which the PFWD protein acts in signal transduction process in a variety of pathways through protein interaction with MYC proteins is proposed. Expand
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.
