nns1 partially reverts nramp3nramp4 phenotypes. (A) Wild-type (Ws), nramp3-1nramp4-1, and nns1 plants were grown vertically for 9 d on ABIS agar medium containing 30 µM CdCl₂ (+Cd). (B) Root length of plants growing on ABIS medium (black bars) or supplemented with 30 µM CdCl₂ (white bars). Data are shown as mean ± SD; n = 27–34 roots. (C) Wild-type (Ws), nramp3-1nramp4-1, and nns1 plants were grown vertically for 7 d on ABIS agar medium without Fe (−Fe). (D) Root length of plants growing on ABIS medium without Fe (white bars) or supplemented with 50 µM Fe-HBED (black bars). Data are shown as mean ± SD; n = 21–31. (Scale bars in A and C: 10 mm.)
