Thermospermine is produced through the action of ACL5 and required for stem elongation. Excess amounts of thermospermine had inhibitory effects on plant growth.
Title: Thermospermine is required for stem elongation in Arabidopsis thaliana.

ACL5 has a prominent role in the correct specification of xylem cells through its action on the duration of xylem element differentiation. [ACAULIS 5] [ACL5]
Title: ACAULIS5 controls Arabidopsis xylem specification through the prevention of premature cell death.

Putative spermine synthases from Arabidopsis thaliana could be identified as thermospermine synthases.
Title: Putative spermine synthases from Thalassiosira pseudonana and Arabidopsis thaliana synthesize thermospermine rather than spermine.

Results suggest a model in which ACL5 plays a role in the translational activation of SAC51, which may lead to the expression of a subset of genes required for stem elongation.
Title: The dwarf phenotype of the Arabidopsis acl5 mutant is suppressed by a mutation in an upstream ORF of a bHLH gene.

The thickvein mutation that affects vein thickness, was found to reside in the ACL5 gene, which encodes a spermine synthase and whose expression is specific to provascular cells. [ACL5]
Title: Arabidopsis thickvein mutation affects vein thickness and organ vascularization, and resides in a provascular cell-specific spermine synthase involved in vein definition and in polar auxin transport.
