“…In our experiment, Brought to you by | MIT Libraries Authenticated Download Date | 5/11/18 11:33 PM Cd treatment strongly reduced the concentration of Fe, slightly decreased that of Mn, but increased the Zn content in leaves of poplar. As severe Mn deficiency produces effects similar to those of Cd [34], the observed slight Mn deficiency may contribute to the Cd caused inhibition of photosynthesis, particularly the PSII activity. Mn and Cd…”

Cadmium (Cd), a highly toxic heavy metal affects growth and metabolic pathways in plants, including photosynthesis. Though Cd is a transition metal with no redox capacity, it generates reactive oxygen species (ROS) indirectly and causes oxidative stress. Nevertheless, the mechanisms involved in long-term Cd tolerance of poplar, candidate for Cd phytoremediation, are not well known. Hydroponically cultured poplar (Populus jacquemontiana var. glauca cv. 'Kopeczkii') plants were treated with 10 μM Cd for 4 weeks. Following a period of functional decline, the plants performed acclimation to the Cd induced oxidative stress as indicated by the decreased leaf malondialdehyde (MDA) content and the recovery of most photosynthetic parameters. The increased activity of peroxidases (PODs) could have a great impact on the elimination of hydrogen peroxide, and thus the recovery of photosynthesis, while the function of superoxide dismutase (SOD) isoforms seemed to be less important. Re-distribution of the iron content of leaf mesophyll cells into the chloroplasts contributed to the biosynthesis of the photosynthetic apparatus and some antioxidative enzymes. The delayed increase in photosynthetic activity in relation to the decline in the level of lipid peroxidation indicates that elimination of oxidative stress damage by acclimation mechanisms is required for the restoration of the photosynthetic apparatus during long-term Cd treatment.

“…Cadmium can cause strong oxidative stress thereby inactivating PSII (quantum efficiency of photosystem II) and the photosynthetic electron transport [13]. However, Cd did not significantly affect the quantum efficiency of photosystem II of the A. lechuguilla seedlings at high concentrations.…”

“…Cd can cause strong oxidative stress, thereby inactivating PSII and photosynthetic electron transport [13]. This element diminishes radicle growth of seedlings and the length of roots of older plants; it also diminishes biomass production, stomatal conductance, transpiration rate, and other metabolic activities [9–11, 13, 14]. Cd also interferes with the capture, transport, and use of several micronutrients such as Fe, Mn, and Zn [10].…”

We investigated if seeds of Agave lechuguilla from contaminated sites with heavy metals were more tolerant to Cd ions than seeds from noncontaminated sites. Seeds from a highly contaminated site (Villa de la Paz) and from a noncontaminated site (Villa de Zaragoza) were evaluated. We tested the effect of Cd concentrations on several ecophysiological, morphological, genetical, and anatomical responses. Seed viability, seed germination, seedling biomass, and radicle length were higher for the non-polluted site than for the contaminated one. The leaves of seedlings from the contaminated place had more cadmium and showed peaks attributed to chemical functional groups such as amines, amides, carboxyl, and alkenes that tended to disappear due to increasing the concentration of cadmium than those from Villa de Zaragoza. Malformed cells in the parenchyma surrounding the vascular bundles were found in seedlings grown with Cd from both sites. The leaves from the contaminated place showed a higher metallothioneins expression in seedlings from the control group than that of seedlings at different Cd concentrations. Most of our results fitted into the hypothesis that plants from metal-contaminated places do not tolerate more pollution, because of the accumulative effect that cadmium might have on them.
