Spermine 10-18 S-adenosyl-L-methionine-dependent methyltransferases superfamily protein Arabidopsis thaliana 177-181 17118338-3 2007 We found that an Arabidopsis mutant plant (acl5/spms), which cannot produce spermine, is hypersensitive to high salt. Spermine 76-84 S-adenosyl-L-methionine-dependent methyltransferases superfamily protein Arabidopsis thaliana 43-47 17118338-3 2007 We found that an Arabidopsis mutant plant (acl5/spms), which cannot produce spermine, is hypersensitive to high salt. Salts 112-116 S-adenosyl-L-methionine-dependent methyltransferases superfamily protein Arabidopsis thaliana 43-47 10944107-2 2000 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 that shares sequence similarity with the polyamine biosynthetic enzymes spermidine synthase and spermine synthase. Polyamines 216-225 S-adenosyl-L-methionine-dependent methyltransferases superfamily protein Arabidopsis thaliana 35-43 10944107-2 2000 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 that shares sequence similarity with the polyamine biosynthetic enzymes spermidine synthase and spermine synthase.
