Mp5g19050 MpR2R3-MYB14 experimental subject R2R3-MYB transcription factor (registered as MpR2R3-MYB14) whose controlled expression drives auronidin pigment accumulation in M. polymorpha. Constitutive and inducible systems were benchmarked, with inducible circuits decoupling biomass from pigment production and giving high yields. The extracted auronidins were used directly to dye cotton yarn.
Mp1g02890 MpE2F experimental tool Its promoter was used to drive the beta-estradiol (XVE) inducible circuit for MpMYB14 expression.
Mp7g07900 MpHSP17.8A1 experimental tool Its promoter was used as the heat-shock-inducible driver for MpMYB14 expression.
Mp5g01410 MpCHIL citation background Chalcone isomerase-like enzyme shown in the auronidin biosynthesis scheme of the paper.
