This article is interesting; don't know if it offers a novel approach to
mercury remediation using transgenic trees but this statement about
mercury-resistant bacteria is interesting. Can these bacteria alone be
cultured on site to remediate mercury in soils?

"Mercury resistant bacteria express merA to convert highly toxic, ionic
mercury, Hg(II), to much less toxic, elemental mercury, Hg(0).
Expression of merA in transgenic plants might provide an ecologically
compatible approach for the remediation of mercury pollution. Yellow
poplar proembryogenic masses (PEMs) were transformed with three modified
merA constructs via microprojectile bombardment."
