Functional analysis of BrMYBL2.1-G and BrMYBL2.1-P for anthocyanin biosynthesis, as a repressor. Visual phenotype and anthocyanin contents in tobacco leaves transiently infiltrated with Agrobacterium strains harboring an empty vector or constructs BrPAP1, BrTT8, BrMYBL2.1-G, and BrMYBL2.1-P in the indicated combinations. (A) Representative photograph of a transiently infiltrated tobacco leaf 5 days after agroinfiltration. (B) Anthocyanin contents of the leaf sections shown in (A). Results are the means ± SD from three independent biological replicates. Different letters indicate significantly different values (p < 0.01), as determined by one-way ANOVA followed by Duncan’s multiple range tests.
