TLDR
This work identified and confirmed additional target genes of the R2R3-MYB subgroup 7 factors, including the UDP-glycosyltransferases UGT91A1 and UGT84A1, and demonstrated that the accumulation of distinct and structurally identified flavonol glycosides in seedlings correlates with the expression domains of the different R2r3- MYB factors.Citations

Regulation of the anthocyanin biosynthetic pathway by the TTG1/bHLH/Myb transcriptional complex in Arabidopsis seedlings.
TL;DR: It is demonstrated that overexpression of Myb113 or Myb114 results in substantial increases in pigment production similar to those previously seen as a result of over-expression of PAP1, and pigment production in these overexpressors remains TTG1- and bHLH-dependent.
Journal ArticleDOI
Flavonoids: biosynthesis, biological functions, and biotechnological applications.
TL;DR: Different strategies and achievements through the genetic engineering of flavonoid biosynthesis with implication in the industry and the combinatorial biosynthesis in microorganisms by the reconstruction of the pathway to obtain high amounts of specific compounds are discussed.
Journal ArticleDOI
Evolutionary and comparative analysis of MYB and bHLH plant transcription factors
TL;DR: This review compares the MYB and bHLH gene families from structural, evolutionary and functional perspectives and suggests that the next few years are likely to witness an increasing understanding of the extent to which conserved transcription factors participate at similar positions in gene regulatory networks across plant species.
Journal ArticleDOI
Recent advances in the transcriptional regulation of the flavonoid biosynthetic pathway
TL;DR: A better knowledge of the regulatory mechanisms of the flavonoids pathway is likely to favour the development of new biotechnological tools for the generation of value-added plants with optimized flavonoid content.

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: Genome-wide analysis of the distribution of integration events revealed the existence of a large integration site bias at both the chromosome and gene levels, and insertion mutations were identified in genes that are regulated in response to the plant hormone ethylene.
