ACAULIS5, an Arabidopsis gene required for stem elongation, encodes a spermine synthase [PDF]
The EMBO Journal, 2000 Polyamines have been implicated in a wide range of biological processes, including growth and development in bacteria and animals, but their function in higher plants is unclear. Here we show that the Arabidopsis: ACAULIS5 (ACL5) gene, whose inactivation causes a defect in the elongation of stem internodes by reducing cell expansion, encodes a protein ...
