Natural variation of TBR confers plant zinc toxicity tolerance through root cell wall pectin methylesterification.

Compared to the Col-0 wildtype, the frd3-3 mutant showed a significant reduction of root growth in response to high Zn according to the 2-way ANOVA ( p < 0.001) while the genotype x treatment interaction was marginally significant for frd3-7 ( p = 0.063) (Fig. 1d, e , Supplementary Fig. 4 and Supplementary Table 2 and 3 ).
