Arabidopsis pab1, a mutant with reduced anthocyanins in immature seeds from banyuls, harbors a mutation in the MATE transporter FFT.

Abstract excerpt

Forward genetics approaches have helped elucidate the anthocyanin biosynthetic pathway in plants. Here, we used the Arabidopsis banyuls (ban) mutant, which accumulates anthocyanins, instead of colorless proanthocyanidin precursors, in immature seeds. In contrast to standard screens for mutants lacking anthocyanins in leaves/stems, we mutagenized ban plants and screened for mutants showing differences in...
