The observed inconsistencies between available in planta, in vitro and in vivo (cell factory) data, however, led us to hypothesize that arGSTs might not (only) have the literature-proposed transport function but could play a central role in the biosynthetic step from leucoanthocyanidins ( 2 ) to anthocyanidins ( 3 )
