Figure 2From: Expression analysis of flavonoid biosynthesis genes during Arabidopsis thaliana silique and seed development with a primary focus on the proanthocyanidin biosynthetic pathwayDevelopmental stages of A. thaliana siliques and single seeds, and accumulation of proanthocyanidins. Developmental stages of A. thaliana siliques are correlated to embryonic stages of single seeds according to Bowman [11], and to the accumulation of proanthocyanidins in the seed coat using vanillin staining.Back to article page
