From: Expression analysis of flavonoid biosynthesis genes during Arabidopsis thaliana silique and seed development with a primary focus on the proanthocyanidin biosynthetic pathway

Figure 4

Expression patterns of selected flavonoid biosynthesis genes during silique and seed development in A. thaliana. 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-C) Seed specific expression of structural flavonoid biosynthesis genes is shown. (D-H) Seed specific expression patterns of proanthocyanidin biosynthesis genes are presented. Color key: blue, siliques containing seeds; green, isolated valves and replum organs; red, isolated seeds. Abbreviations are as follows: AHA10 P-type H+-ATPase, BAN anthocyanidin reductase, CHS chalcone synthase, DFR dihydroflavonol 4-reductase, LDOX leucoanthocyanidin dioxygenase, TIM44-2 translocase inner membrane subunit 44-2, TT transparent testa, TT10 laccase-like, TT12 multidrug and toxic compound extrusion-type transporter, TT19 glutathione S transferase.
