“…1). The P-phytoremediation capacity of willow has been already reported [46][47][48], and therefore, was not the focus of our study. However, we demonstrated here that the higher P concentration found in PO 4 3-fertilized plants may have a role in the plant's physiological responses to glyphosate.…”

HighlightsPhosphate increased glyphosate uptake and decreased its toxicity in willows PO 4 3-concentrations ≥ 200 mg l -1 doubled glyphosate uptake by willow roots PO 4 3-concentrations ≥ 200 mg l -1 increased antioxidant system activity PO 4 3-maintained photosynthesis rates by inducing reactive oxygen species scavenging 3 Abstract Phosphate (PO 4 3-) has been shown to increase glyphosate uptake by willow, a plant species known for its phytoremediation potential. However, it remains unclear if this stimulation of glyphosate uptake can result in an elevated glyphosate toxicity to plants (which could prevent the use of willows in glyphosate-remediation programs). Consequently, we studied the effects of PO 4 3-on glyphosate uptake and toxicity in a fast growing willow cultivar (Salix miyabeana SX64). Plants were grown in hydroponic solution with a combination of glyphosate (0, 0.001, 0.065 and 1 mg l -1 ) and PO 4 3-(0, 200 and 400 mg l -1 ). We demonstrated that PO 4 3-fertilization greatly increased glyphosate uptake by roots and its translocation to leaves, which resulted in increased shikimate concentration in leaves. In addition to its deleterious effects in photosynthesis, glyphosate induced oxidative stress through hydrogen peroxide accumulation.Although it has increased glyphosate accumulation, PO 4 3-fertilization attenuated the herbicide's deleterious effects by increasing the activity of antioxidant systems and alleviating glyphosateinduced oxidative stress. Our results indicate that in addition to the glyphosate uptake, PO 4 3-is involved in glyphosate toxicity in willow by preventing glyphosate induced oxidative stress.

“…and willow (Salix sp., Box 2) because they propagate readily from vegetative cuttings, or 'live poles,' if placed immediately in contact with moist soil (Wilkinson 1999;McIvor et al 2014). Willow species, in particular, are also used for a range of functions in riparian areas, including streambank protection and nutrient and sediment management (Kuzovkina and Volk 2009). Unlike seedlings or saplings, which possess root systems that develop close to the soil surface, cuttings (i.e., before the root system has developed) can be buried to a depth of up to 2.0 m in the soil.…”

Ecological mitigation of hillslope instability: ten key issues facing researchers and practitioners

et al. 2014

Background Plants alter their environment in a number of ways. With correct management, plant communities can positively impact soil degradation processes such as surface erosion and shallow landslides. However, there are major gaps in our understanding of physical and ecological processes on hillslopes, and the application of research to restoration and engineering projects.Scope To identify the key issues of concern to researchers and practitioners involved in designing and implementing projects to mitigate hillslope instability, we organized a discussion during the From this discussion, ten key issues were identified, considered as the kernel of future studies concerning the impact of vegetation on slope stability and erosion processes. Each issue is described and a discussion at the end of this paper addresses how we can augment the use of ecological engineering techniques for mitigating slope instability. Conclusions We show that through fundamental and applied research in related fields (e.g., soil formation and biogeochemistry, hydrology and microbial ecology), reliable data can be obtained for use by practitioners seeking adapted solutions for a given site. Through fieldwork, accessible databases, modelling and collaborative projects, awareness and acceptance of the use of plant material in slope restoration projects should increase significantly, particularly in the civil and geotechnical communities.

“…Generally, phytoremediation and especially phytoextraction rely on plants known as hyperaccumulators; however, these are species that often have a low biomass and slow growth rate, leading to a long time periods required for metal removal (Tanhan et al, 2007). Recently, willows have been shown to be good candidates for remediating metal-contaminated sites because of their rapid growth, large biomass, deep roots, and high accumulation capacity for heavy metals (Kuzovkina and Quigley, 2005;Kuzovkina and Volk, 2009). In the last decade, short-rotation willow coppices have provided an economic and practical solution for remediation as well as for bioenergy production (Rockwood et al, 2004;Mirck et al, 2005).…”

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.
