WHOLE PLANT, ENVIRONMENTAL, AND STRESS PHYSIOLOGY

A Metal-Accumulator Mutant of Arabidopsis thaliana

A mutation designated man1 (for manganese accumulator) was found to cause Arabidopsis thaliana seedlings to accumulate a range of metals. The man1 mutation segregated as a single recessive locus located on chromosome 3. When grown on soil, mutant seedlings accumulated Mn (7.5 times greater than wild type), Cu (4.6 times greater than wild type), Zn (2.8 times greater than wild type), and Mg (1.8 times greater than wild type) in leaves. In addition to these metals, the man1 mutant accumulated 2.7-fold more S in leaves, primarily in the oxidized form, than wild-type seedlings. Analysis of seedlings grown by hydroponic culture showed a similar accumulation of metals in leaves of man1 mutants. Roots of man1 mutants also accumulated metals, but unlike leaves they accumulated 10-fold more total Fe (symplasmic and apoplasmic combined) than wild-type roots. Roots of man1 mutants possessed greater (from 1.8- to 20-fold) ferric-chelate reductase activity than wild-type seedlings, and this activity was not responsive to changes of Mn nutrition in either genotype. Taken together, these results suggest that the man1 mutation disrupts the regulation of metal-ion uptake or homeostasis in Arabidopsis.
