From: Differential mercury volatilization by tobacco organs expressing a modified bacterial merA gene
Northern hybridization of transgenic plant lines of tobacco. Total RNA of lines was hybridized with α 32P-labeled BamHI- XhoI merApe9 fragment. MerA-3 and MerA-2, two of transgenic lines, was shown to have strong signal of transcriptional expression while wild type (WT) of tobacco were indicated without signal of expression.
