“…Previous reports indicated that S. bonariensis plants immobilize As (Cuadra et al, 2019), Zn, Cu, Ni, and Cr in their biomass. These elements were also found in the extra-and intraradical AM fungal mycelia of mycorrhizal S. bonariensis plants (Benavidez et al, 2014).…”

Mycorrhizal stress alleviation in Senecio bonariensis Hook & Arn growing in urban polluted soils

Loss of biodiversity and accumulation of contaminants in urban soils and water bodies cause serious issues in metropolitan areas. The Matanza-Riachuelo river basin (metropolitan area of Buenos Aires, Argentina) is one of the most environmentally degraded regions in the world. Senecio bonariensis Hook & Arn (Asteraceae) grows in the periodically flooded soils of this wetland. This plant concentrates potentially toxic trace elements (PTEs) in its tissues and establishes symbiosis with arbuscular mycorrhizal (AM) fungi that collaborate with PTE phytostabilization in soils. The objective of this work was to evaluate tolerance and stress alleviation of AMcolonized S. bonariensis when transplanting and exposing to highly polluted environmental conditions of the river basin. Plants were initially inoculated with different AM strains and maintained in greenhouse conditions. After 6 mo, they were transplanted to the field. These plants showed a more equal distribution between shoot and root biomass production in comparison to field spontaneous S. bonaerensis plants. Plants in earlier contact with native soil inoculum showed positive correlation with phosphorus content and a significant increase of vesicle frequency. Plants belatedly contacted with native inoculum in the field (control) showed a higher catalase level that was positively correlated with the total colonization frequency and chlorophyll content. The ability to establish symbiosis with Rhizophagus intraradices (strain GC3), commonly used in the formulation of biofertilizers, was also analyzed. Plants inoculated with GC3 at the beginning of the assay showed lower colonization and were less efficient in the field. The preservation of spontaneous native plants with ornamental value and bioaugmentation of their associated microbiome can contribute to the stabilization of contaminants in soils.

“…Relating to As accumulation, Alderete-Suarez, Valles-Aragón, Canales-Reyes, Peralta-Pérez, and Orrantia-Borunda (2019), working with Eleocharis macrostachya during 210 days, obtained As concentrations in roots ranging from 42.8, 47.7 to 49.0 mg/kg in plants treated with 2, 4, and 8 mg/L of As. Cuadra et al (2019) conducted a study in controlled and uncontrolled conditions with the aim of analyzing As bioaccumulation capacity of Senecio bonariensis and in which organs greater accumulation of this element was observed. In the experiment with controlled conditions, the plants treated with higher concentrations of As had greater values of biomass.…”

Arsenic-contaminated waters represent environmental and public health problems. The use of plants has emerged as a viable, cost-effective, and low environmental impact alternative to treat these polluted waters. This review presents studies published in the year 2019 on phytoremediation covering the effects observed on plants, trends in plant species selection and treatment of arsenic-rich biomass. Studies on application of this technology are exposed through constructed (treatment) wetlands, and a brief contextualization on the impacts of arsenic contamination was also performed.

“…Phytoremediation is still in research and development phase, with many technical issues needing to be addressed [1], for example most of the experiments have taken place on a laboratory scale, with plants grown in hydroponic settings fed heavy metal diets, so in this sense agronomic management practices and plant genetic abilities need to be optimized to develop commercially useful practice [1]. Although in recent years there have been more investigations that provide innovative data in the application of these technologies [17,18]. The most important factor for the phytoremediation process to be successful is a suitable plant species which can be used to uptake the contaminants [18].…”
