Arabidopsis thaliana - 654366, 689535 Arabidopsis thaliana gene BANYULS orthologue, BAN 713331 Arabidopsis thaliana genetic transformation of Arabidopsis thaliana with the Arabidopsis TT2 MYB transcription factor results in ectopic expression of the BANYULS gene, encoding anthocyanidin reductase, AHA10 encoding a P-type proton-pump and TT12 encoding a transporter involved in proanthocyanidin biosynthesis. When coupled with constitutive expression of PAP1, a positive regulator of anthocyanin biosynthesis, TT2 expression in Arabidopsis leads to the accumulation of proanthocyanidins, but only in a subset of cells in which the BANYULS promoter is naturally expressed. Ectopic expression of the maize Lc MYC transcription factor weakly induces AHA10 but does not induce BANYULS, TT12 or accumulation of proanthocyanidins 676500 Arabidopsis thaliana Wassilevskija-2 ecotype gene BANYULS orthologue, BAN 713331 Betula pendula - 745994 Brassica napus gene BANYULS orthologue, four copies of BAN, two originating from each diploid progenitor 713331 Brassica napus Westar gene BANYULS orthologue, four copies of BAN, two originating from each diploid progenitor 713331 Brassica oleracea gene BANYULS orthologue, BAN 713331 Brassica rapa gene BANYULS orthologue, BAN 713331 Brassica rapa subsp. oleifera gene BANYULS orthologue, BAN 713331
