Leaky Expression

In repressed state, an occasional transcript gets made. This happens because every so often, RNA polymerase will manage to bind the promoter in place of the Lac repressor. This leakiness encode meager level of Z, Y and A.

Phytovolatilization

Plants remove inorganic contaminants· either by contaminant volatilization or by metal accumulation.

Volatalization is useful for the removal of mercury. A bacterial mercuric ion reductase has been transferred to Arabidopsis thaliana; this transgenic plant absorbs mercury, and reduces it to volatile Hg0, which volatilizes from the leaf surface.
