General Information

General Information Comment Organism
physiological function thermospermine-deficient mutant acl5 shows severe dwarfism and excessive xylem differentiation. Some auxin analogs remarkably enhance xylem vessel differentiation in the acl5 mutant but not in the wild type. The xylem-inducing effect of auxin analogs is clearly suppressed by thermospermine. Auxin analogs promote protoxylem differentiation in roots and cotyledons in the acl5 mutant. The opposite action between thermospermine and auxin in xylem differentiation may be common in different organs and thermospermine might be required for the suppression of protoxylem differentiation Arabidopsis thaliana
