Polyamine Xylemin Induces Xylem Differentiation with Synthetic Proauxin
Xylemin dihydrochloride (X0080) is a polyamine whose unique function was reported by Takahashi, Motose and co-workers.¹) It promotes xylem differentiation when co-treated with the synthetic proauxin 2,4-D IOE (O0518), acting by inhibiting thermospermine biosynthesis, which otherwise suppresses xylem differentiation. In cotyledons of Arabidopsis thaliana, the combination shows a synergistic effect on ectopic xylem differentiation, while application to the shoot apex of A. thaliana has a dwarfing effect. Xylemin is anticipated to be used in research and development of agrochemicals and biomass energy.
