Innate, High Tolerance to Zinc and Lead in Violets Confirmed at the Suspended Cell Level.

ABSTRACT: Many species of the Viola L. genus (violets) colonize areas with high concentrations of trace elements in the soil, e.g., nickel, cadmium, zinc, and lead. Although tolerance to heavy metals is a common phenomenon in violets, it is not clear whether this is the result of gradual microevolutionary processes as a part of the adaptation to the specific conditions, or whether the tolerance was inherited from the ancestor(s). We developed cell suspension cultures of five plant species: two non-metallophytes-Arabidopsis thaliana (Col-0) and Viola · wittrockiana, and three metallophytes-V. philippica, V. tricolor, and Silene vulgaris subsp. humilis for tolerance tests. The aim of the study was to measure the level of tolerance of violets in c
