THERmospermine 是精胺的结构异构体，在抑制木质部分化中发挥作用。THERmospermine 可用于作为植物生长调节剂和控制木材生物质生产的研究。

Thermospermine is a structural isomer of spermine and plays a role in the repression of xylem differentiation. Thermospermine can be used in studies about acting as a plant growth regulator and serving in the control of wood biomass production.

The mutant defective in the biosynthesis of thermospermine, ACL5, shows a dwarf phenotype with excess xylem vessels in Arabidopsis thaliana. Exogenous supply of thermospermine remarkably represses xylem differentiation in the root of seedlings. Rice showed up-regulation of phloem-expressed genes, OsHB5 and OsYSL16, by one-day treatment with thermospermine.Expression of OsPAO2 and OsPAO6, encoding extracellular polyamine oxidase whose orthologs are not present in Arabidopsis, was induced by both thermospermine and spermine[3].
