Growth and physiological effects of single and combined Cu, NaCl, and water stresses on Atriplex atacamensis and A. halimus

Use of Halophytes for the Remediation of Metal-Affected Soils in Arid Environments

“…Similar to the results of Min-Wei Chai (2012), metal accumulation was positively related to the synthesis of different organic compounds on each organ: in roots, it was related to amino acids and other organic acids, but in leaves it was related to a subgroup of amino and organic acids, along with phytochelatins, a peptide that has been widely described as a metal chelator (Cheng et al 2018). A possible effect of phytochelatins on metal accumulation was also described by Orrego et al (2020) on seedlings of Atriplex halimus and A. atacamensis subjected to increasing Cu concentration. On this study, they found that both species accumulated higher concentrations of Cu in roots than shoots.…”

Increase in Phytoextraction Potential by Genome Editing and Transformation: A Review

“…In these cases, a combination of two or more abiotic stressors may occur and result in a new condition for plant development, different from the effect of each stressor by itself [ 108 , 109 ]. Thus, plant selection for phytoextraction must also consider the presence of multiple co-occurring stressors and their effects on plant growth and development [ 110 ]. Abandoned mine tailings sites are a global problem, with thousands of unvegetated, exposed tailings piles presenting a source of contamination for nearby communities.…”
