Figure 5

Expression patterns of selected proanthocyanidin and anthocyanin accumulation genes during silique and seed development. qPCR analyses were performed to verify ATH1 GeneChip expression values. Relative transcript levels (bars, primary axis; normalized to TIM44-2) correlate to log2 expression values of ATH1 GeneChips (curve, secondary axis). (A) Expression patterns of regulatory genes responsible for proanthocyanidin accumulation are shown during A. thaliana silique and seed development. (B) Anthocyanin accumulation-associated genes show global faint gene expression. PAP1 and UGT75C1, which is known to be regulated by PAP1 are significantly up-regulated at early developmental stages. Color key: blue, siliques containing seeds; green, isolated valves and replum organs; red, isolated seeds. Abbreviations are as follows: PAP production of anthocyanin pigments, TIM44-2 translocase inner membrane subunit 44-2, TT transparent testa, TTG transparent testa glabra, UGT75C1 UDP dependent glycosyltransferase.
