Other claims from this paper (4)
- Observation In three metal-tolerant clones up to 95% of buffer-soluble Cu and Ni was in the metal-peptide fraction after 1 h of exposure, with little change afterwards.
- Observation The non-tolerant clone bound only 2% of the metal after 1 h.
- Observation Copper in the peptide fraction remained low over 24 h of exposure.
- Association Metal tolerance is, in some cases, related to the ability of roots to rapidly bind the metal that enters cells.
