The Disruption of MED5a/b Restores Phenylpropanoid Content in ref5-1.

(A) Morphology and ref phenotype in 3-week-old ref5-1 med5a/b triple mutant compared with its single mutants. ref5-1 med5a/b plants exhibit the high auxin phenotypes similar to ref5-1 but the ref phenotype is suppressed.

(B) to (E) Soluble metabolite analysis in mature leaves and seedling roots. Sinapoylmalate and sinapoylglucose content was measured in 3-week-old whole rosette leaves ([B] and [C]). Syringin and coniferin content was measured in 2-week-old seedling roots ([D] and [E]). Asterisks indicate P < 0.01 by a two-tailed Student’s t test compared with ref5-1.
