From: Differential mercury volatilization by tobacco organs expressing a modified bacterial merA gene
Amount of Hg0 released from 20-d old transgenic tobacco seedlings from kanamycin-containing medium. Leaves, roots and stems without leaf were cut from seedlings of transgenic line MerA9-3 and WT (wild-type) and dipped in HgCl2 solution for evolution of Hg0. Amount of Hg0 evolved was indicated with microgram of Hg0 per gram of fresh plant tissue (μg/g).
