Flavonoids: a colorful model for the regulation and evolution of biochemical pathways
TL;DR: The analysis of pigmentation continues to provide insights into new areas, such as the channeling and intracellular transport of metabolites, regulation of gene expression and RNA interference.

The flavonoid biosynthetic pathway in plants: Function and evolution
TL;DR: Based on taxonomy and molecular analysis of gene expression patterns it is possible to deduce a putative sequence of acquisition of the different branches of the biosynthetic pathway and their regulators.

Molecular Analysis of the anthocyanin2 Gene of Petunia and Its Role in the Evolution of Flower Color
Francesca Quattrocchio,John F. Wing,Karel van der Woude,Erik Souer,Nick de Vetten,Joseph N. M. Mol,Ronald Koes +6 more
TL;DR: Analysis of molecular events at the an2 locus that occur during Petunia spp evolution suggests that the loss of an2 function and the consequent changes in floral color were not the primary cause for genetic separation of P. integrifolia and P. axillaris.
Analysis of bHLH and MYB domain proteins: species-specific regulatory differences are caused by divergent evolution of target anthocyanin genes.
TL;DR: The isolation of a P. hybrida gene, jaf13, encoding a basic helix-loop-helix protein, indicates that regulatory anthocyanin genes are conserved between species and that divergent evolution of the target gene promoters is responsible for the species-specific differences in regulatory networks.

PH4 of Petunia Is an R2R3 MYB Protein That Activates Vacuolar Acidification through Interactions with Basic-Helix-Loop-Helix Transcription Factors of the Anthocyanin Pathway
Francesca Quattrocchio,Walter Verweij,Arthur Kroon,Cornelis Spelt,Joseph N. M. Mol,Ronald Koes +5 more
TL;DR: The finding that An1 domains required for anthocyanin synthesis and vacuolar acidification can be partially separated suggests that AN1 activates different pathways through interactions with distinct MYB proteins.
