Evidence for axial shoot-to-root transport of jasmonate (or jasmonate precursors). JAZ10p:GUS reporter activity in grafted 13-d-old seedlings of the indicated scion/rootstock genotypes: WT/WT grafts (A and B), aos/aos grafts (C and D), aos/WT grafts (E and F), and WT/aos grafts (G and H). One of the two cotyledons was excised before grafting. GUS staining was performed 3 h after wounding aerial organs with a needle at sites indicated by orange asterisks (B, D, F, and H). Note the presence of reporter activity in the rootstock of the wild-type (WT)/aos grafted plant. Black arrowheads indicate grafting sites, and red arrowheads indicate reporter activity in the root. Bars = 1 mm.
