Plus de détailsHyperaccumulator plants and the need for a database. Hyperaccumulators are unusual plants that accumulate particular metals or metalloids in their living tissues to levels that may be hundreds or thousands of times greater than is normal for most plants (Reeves, 2003; van der Ent et al., 2013).Hyperaccumulator plants are of substantial fundamental interest and practical importance.

Plus de détailsThe consensus zinc finger, without doubt, is the most explored zinc finger so far in terms of its metal binding properties, stability, reactivity and applications in biotechnology [238], [239], [240]. Very early studies showed that this artificial (non-natural) peptide binds Zn (II) very tightly.
