Genetic segregation analysis suggested that the Rd and A loci are identical, and both encode dihydroflavonol-4- reductase (DFR). WebbProanthocyanidin (PA), or condensed tannin, is a polymeric flavanol that accumulates in a number of tissues in a wide variety of plants. In Arabidopsis, we found that PA precursors (detected histochemically using OsO(4)) accumulate in the endothelial cell layer of the seed coat from the two-terminal cell stage of embryo development onwards. af reserve pay calculator
