For some plants accumulation of metals appears to be an active process possibly related to a tolerance mechanism for their survival on contaminated sites. For such plants leaf concentrations of heavy metals can reach high levels (for example around 1% for zinc or manganese, and 0.1% for cadmium, on a dry matter basis). In Europe these plants tend to be members of the Brassicaeae and are generally found on "naturally" contaminated soils, such as serpentine soils. These plants are referred to as "hyperaccumulators" to distinguish the nature of their metal accumulation from passive accumulation processes ...  2, record 1, English, - hyperaccumulation

[Chez certaines plantes] ces teneurs [en polluants(métaux lourds]) très supérieures aux niveaux habituellement rencontrés ont donné leur nom aux plantes hyperaccumulatrices, et la notion d’hyperaccumulation. Cette propriété d’hyperaccumulation est la conséquence d’une autre propriété, l'hypertolérance(ou phytotolérance) développée par ces plantes au cours de l'évolution, dans les conditions hostiles et toxiques des sites métallifères.  1, record 1, French, - hyperaccumulation

L’hyperaccumulation semble avoir une grande importance écologique. Elle influerait notamment sur la résistance à la sécheresse, les interactions avec les plantes adjacentes et la défense contre les herbivores et les bactéries pathogènes.  1, record 1, French, - hyperaccumulation

The hypertolerance of metals is the key plant characteristic required for hyperaccumulation; vacuolar compartmentalization appears to be the source of hypertolerance of natural hyperaccumulator plants.  3, record 2, English, - hypertolerance

This capacity for accumulation is due to hypertolerance, or phytotolerance: the result of adaptative evolution from the plants to hostile environments along multiple generations.  2, record 2, English, - hypertolerance

Just as adaptative evolution by natural selection is less easy in a small population of a species than in a larger one, because the total pool of genetic variability is inevitably less, so it is probable that a group containing many diversified species will be able to seize new evolutionary opportunities more easily than an undiversified group.  3, record 3, English, - adaptative%20evolution
