“…Common plant seedlings, such as rice, Arabidopsis, and maize, experienced mortality under 0.5 mM Zn stress (Song ZZ, Guo SL, Ma RJ and Yu ML, unpublished results). Despite this, certain plant species, such as Silene vulgaris and Halimione portulacoides, have evolved a tolerance to Zn that enables them to grow in Zn-contaminated soils, remaining unaffected by the elevated Zn levels (Ernst et al, 2000;Cambrollé et al, 2012).…”
