TL;DR:
To understand how 2,4-dichlorophenoxyacetic acid, an auxin, regulates the PAP1-activated anthocyanin biosynthesis, five different concentrations were tested and showed that the five concentrations reduced the expression levels of the constitutive P AP1 transgene and three pathway genes significantly and eliminated the expression of the chalcone synthase gene either significantly or slightly.
