  abstract = {{H}irschfeldia incana is a pseudometallophyte belonging to the {B}rassicaceae family identified in a lead ({P}b) mining area in eastern {M}orocco. {G}rowth, {P}b accumulation and some physiological characteristics were compared in a metallicolous ({MP}) and a non-metallicolous population ({NMP}) of {H}. incana. {P}lants from the {MP} were more tolerant to {P}b than those from the {NMP} in both soil and hydroponic culture. {I}n hydroponic culture, when supplied with 100 mu {M} of {P}b, {P}b accumulation in the aboveground parts of {NMP} plants was 2.5 times higher than in {MP} plants. {MP} plants had significantly lower concentrations of anthocyanins and higher concentrations of chlorophyll a than {NMP}. {M}olecular analyses revealed that {HMA}4 and {MRP}14 genes were regulated by {P}b in the leaves of both {MP} and {NMP}. {I}nterestingly, the {MRP}14 gene was constitutively more expressed in {NMP} suggesting possible adaptation of the {MP} via regulation of {P}b accumulation. {O}ur results show that plants from the metallicolous population has adapted to tolerate and accumulate {P}b and thus have good potential for phytoremediation of {P}b contaminated soil.},
