Arabidopsis flowers accumulate the sulfur by-product methylthioadenosine when methionine salvage is reduced, lowering methylation capacity and impairing fertility. Short-term spermidine treatment partly restores growth- Tremblay et al.

Fig. 2 (shortened, full legend in paper): Partial restoration of mtn1-1mtn2-1 phenotypes across developmental milestones. (A) Representative confocal images of 7-day-old Col-0 (WT), mtn1-1mtn2-1, and G3 roots obtained using the SR2200 cell wall stain, with the red asterisk indicating the end of the meristematic zone measuring from isodiametric cells of the QC to the first cell that doubles in length in the cortex cell layer. Scale bar=100 µm. (B) The length of the meristematic zone was measured, indicated by the red asterisk in (A). Statistical testing was performed using two-way Kruskal–Wallis tests with Dunn’s post-hoc test. Groups not sharing letters are significantly different (P<0.05; n=15). (C) After the WT, mtn1-1mtn2-1, and G3 plants reached ∼25 cm in height, the first 10 internodes between siliques were measured on the primary inflorescence branch for both Spd-treated and untreated plants and summarized in a PCA (n=15).
