“…3 indicate that clones accumulated higher percentages of Cu in the roots than in aerial parts, which is in agreement with previous reports (Ali et al, 2003;Kuzovkina et al, 2004;Borghi et al, 2007;Castiglione et al, 2009). The distribution pattern of Cu in plant parts was ranked in the order of roots>stems>leaves.…”

Willows (Salix spp.) have shown high potential for the phytoextraction of heavy metals. This study compares variations in copper (Cu) and zinc (Zn) tolerance and accumulation potential among 12 willow clones grown in a nutrient solution treated with 50 μmol/L of Cu or Zn, respectively. The results showed differences in the tolerance and accumulation of Cu and Zn with respect to different species/clones. The biomass variation among clones in response to Cu or Zn exposure ranged from the stimulation of growth to inhibition, and all of the clones tested showed higher tolerance to Cu than to Zn. The clones exhibited less variation in Cu accumulation but larger variation in Zn accumulation. Based on translocation factors, it was found that most of the Cu was retained in the roots and that Zn was more mobile than Cu for all clones. It is concluded that most willow clones are good accumulators of Zn and Cu.

“…The metal might be recovered in the aerial parts (Castiglione et al 2007). At leaf level, heavy metals can strongly alter leaf morphology and ultrastructure (Lingua et al 2008, Castiglione et al 2009, and negatively affect PSII activity, decreasing D1 and D2 reaction center proteins, but not light harvesting antenna system (LHCII) and protein expression (Todeschini et al 2011). Iori et al (2012) have observed that the high tolerance of a clone might be associated to the activity of antioxidative enzymes and the ability to increase thiol and phytochelatin concentrations in response to metal exposure.…”

“…Clone-specific metal mobility through plant compartments may induce exclusion of metals in shoot tissue relative to soil concentrations in Salicaceae (e.g., Castiglione et al 2009). Detoxification of heavy metals, especially non-essential heavy metals, is often attributed to post-translationally synthesized thiol-rich short metal binding proteins termed phytochelatins (Grill et al 1985).…”

“…Nevertheless, despite intensive research over the past decades, the real potential of phytoremediation has not been fully clarified due to the scarcity of field trials (Van Nevel et al 2007). These are essential to identify the complex set of sitespecific interactions between soil, plant, pollutant(s) (Castiglione et al 2009) and soil microbial populations (Cicatelli et al 2012).…”

“…Microorganism activity has been found to play a role in increasing both the plant biomass (Gamalero et al 2009) and the protective action against pollutants (Cicatelli et al 2010). The proteomic approach has been applied to depict changes in a specific pattern of protein expression (Lingua et al 2012), such as the enhanced expression of metallothioneins (Cicatelli et al 2012) and polyamines (Castiglione et al 2009). …”

Poplars and willows (and other fast growing tree species) form an important component of agroforestry systems, providing a wide range of ecosystem services and products. The workshop held in Capracotta (6th and 7th June 2012) has communicated the latest research on poplars and willows in the field of environmental restoration conducted in Italy, providing a condensed overview on their basic response to pollutants and use in environmental monitoring, highlighting future challenges of phytotechnology issues. In the frame of the project MIUR-PRIN 2008 “Molecular, physiological, and agronomic analyses for selecting and managing Salicacee in phytoremediation”, 17 talks were delivered to an audience of more than 50 researchers. Prominence was given to stress biology and the importance of poplar and willow breeding in meeting the needs of ecological restoration. The aim of this review is provide a timely account of the questions related to phytotechnology in shaping the multifunctional tree, particularly with regard to tree responses to environmental pollution. While the question is scientifically challenging, progress may be achieved by exposing the different environmental restoration models and underlying guiding principles to tests against experimental data and each other. Research and development should focus simultaneously on maximizing the yield of multipurpose tree plantations, while preserving or restoring ecosystem services of close-to-nature willow-poplar stands (e.g., riparian forests). We hope that this review will stimulate further studies in this interesting area of tree biology
