TL;DR: 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.

TL;DR: 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.

TL;DR: This work down-regulated the endogenous dihydroflavonol 4-reductase (DFR) gene and overexpressed the Irisxhollandica DFR gene in addition to the viola F3'5'H gene in a rose cultivar, resulting in the accumulation of a high percentage of delphinidin and a novel bluish flower color.

TL;DR: The precise identification of flavonoids in conjunction with transcriptomics led to the identification of a gene function and a more complete understanding of a plant metabolic network.

TL;DR: The strategy of combining transcriptome and metabolome as a powerful technology for studying the functional genomics of model plants and also crop and medicinal plants is reviewed.
