  abstract = {{H}irschfeldia incana, a pseudometallophyte belonging to the {B}rassicaceae family and widespread in the {M}editerranean region, was selected for its ability to grow on soils contaminated by lead ({P}b). {T}he global comparison of gene expression using microarrays between a plant susceptible to {P}b ({A}rabidopsis thaliana) and a {P}b tolerant plant ({H}. incana) enabled the identification of a set of specific genes expressed in response to lead exposure. {T}hree groups of genes were particularly over-represented by the {P}b exposure in the biological processes categorized as photosynthesis, cell wall, and metal handling. {E}ach of these gene groups was shown to be directly involved in tolerance or in protection mechanisms to the phytotoxicity associated with {P}b. {A}mong these genes, we demonstrated that {MT}2b, a metallothionein gene, was involved in lead accumulation, confirming the important role of metallothioneins in the accumulation and the distribution of {P}b in leaves. {O}n the other hand, several genes involved in biosynthesis of {ABA} were shown to be up regulated in the roots and shoots of {H}. incana treated with {P}b, suggesting that {ABA}-mediated signaling is a possible mechanism in response to {P}b treatment in {H}. incana. {T}his latest finding is an important research direction for future studies.},
