-
stems and flowers contain two- to threefold more thermospermine compared to whole seedlings and mature leaves
strong ACL5 expression is present in the megagametophyte cells destined to die via morphologically necrotic cell death
in developing seeds, the expression of both ACL5 and diamine oxidase increases as embryogenesis proceeds
strong ACL5 expression is present in the procambial cells of the embryo and in the megagametophyte cells destined to die via morphologically necrotic cell death
strong ACL5 expression is present in the procambial cells of the embryo

in the hypocotyl as well as in the inflorescence stem, ACL5 is expressed not just broadly with respect to vasculature, but specifically in the xylem vessel elements at a strictly defined developmental stage, suggesting direct involvement of ACL5 in xylem vessel differentiation. The acl5 mutant displays severe overall inhibition of the secondary growth of the vascular tissues, dramatic alteration in the morphology of the vessel elements and complete lack of xylem fibers
the enzyme is expressed specifically in early developing xylem vessel elements
