Fig. 3 in Acropetal and basipetal cardenolide transport in Erysimum cheiranthoides (wormseed wallflower)

Fig. 3. Maternal genotype determines seed cardenolide phenotype. Seed cardenolide content was measured in seeds from naturally self-pollinated and manually crossed plants. Different letters indicate P <0.05 differences for each cardenolide, ANOVA followed by Tukey's HSD test. Bars are mean ± s.d. of N = 4–5. wt = wildtype E. cheiranthoides var. Elbtalaue, 454 = 454 cardenolide mutant line. Peak areas were normalized to an ouabain internal standard.
