Suppression of the dwarf phenotype of an Arabidopsis mutant defective in thermospermine biosynthesis by a synonymous codon change in the SAC51 uORF
Thermospermine plays a critical role in negatively regulating xylem development in angiosperms. A mutant of Arabidopsis thaliana that is defective in thermospermine biosynthesis, acaulis5 (acl5), exhibits a dwarf...
