Abstract excerpt

Arabidopsis TRANSPARENT TESTA19 (TT19) encodes a glutathione-S-transferase (GST)-like protein that is involved in the accumulation of proanthocyanidins (PAs) in the seed coat. PA accumulation sites in tt19 immature seeds were observed as small vacuolar-like structures, whereas those in tt12, a mutant of the tonoplast-bound transporter of PAs, and tt12 tt19 were observed at peripheral regions of small vacuoles. We...
