From: A novel R2R3-MYB from grape hyacinth, MaMybA, which is different from MaAN2, confers intense and magenta anthocyanin pigmentation in tobacco

Relative expression of anthocyanin biosynthetic genes and endogenous transcription factor (TF) genes in the leaves and corollas of the control, OE-MaAN2, and three independent OE-MaMybA transgenic plants (OE#1, OE#2, and OE#3). The expression profiles of MaMybA in the leaves (a) and corollas (d) of the control, OE#1, OE#2, and OE#3; the expression profile of MaAN2 in the leaves (a) and corollas (d) of the OE-MaAN2 tobacco; the expression levels of anthocyanin biosynthetic genes (NtCHS, NtCHI, NtF3H, NtF3′H, NtF3′5′H, NtDFR, NtANS, and NtUFGT) in the leaves (b) and corollas (e) of different tobacco genotypes; and the relative expression of three endogenous TF genes (NtAN2, NtAn1a and NtAn1b) in the leaves (c) and corollas (f) of different tobacco genotypes. NtTubA1 was used as the internal control. Error bars indicate the standard deviations (SD) of average results
