“…The discrepancies are presumably due to variation in the biomass allocation strategy of Salix genotypes in response to excess Fe and Mn (Yang et al ). These results are consistent with previous findings that indicated extensive genotypic variation in biomass production in response to Fe and Mn (Yang et al , ). Similarly, Shanahan et al () reported genotypic differences of Salix in response to Mn.…”

“…SB7 ( Salix babylonica ), SM29 ( Salix matsudana ), and SM30 ( S. matsudana ) are elite genotypes of willows with high biomass production; J9‐6 ( Salix integra × Salix suchowensis ) is a shrub willow hybrid; J194 ([ S. matsudana × Salix chosenia arbutifolia ] × S. matsudana ), J799 ( S. matsudana × Salix alba ), J842 ( S. babylonica × S. alba ), and J903 ([ S. matsudana × S. chosenia arbutifolia ] × S. matsudana ) are tree willow hybrids. The genotypes were selected for their high biomass, tolerance to Fe and Mn exposure, and resistance to multiple abiotic stresses such as flooding (Yang et al , ).…”

“…The tolerance index (TI), the ratio between a variable measured in treated and control plants, was calculated using plant shoot and root biomass. The transfer factor (TF), the ratio of the metal concentration in leaves or stems vs. that in roots, was used to estimate the translocation Fe or Mn from roots to shoots (Yang et al , ).…”

“…Numerous studies have indicated that willows ( Salix spp.) can accumulate heavy metals (e.g., Cd, Cu, Zn, Mn, and Fe) from contaminated soils and water into their shoot tissues (Shanahan et al ; Yang et al ; Yang et al , , ). Willows are suitable for phytofiltration because of their multiple advantages such as rapid plant growth, vigorous root system, high transpiration capacity, fast nutrient uptake, and high flooding tolerance (Kuzovkina and Volk ; Pistocchi et al ).…”

“…These species provide a rich resource to screen suitable Salix genotypes for improving phytoremediation efficiency of contaminated groundwater. Recent studies have shown that the removal efficiency of Fe and Mn by willows is dependent on the selection of suitable genotypes (Yang et al , ). Selecting Salix genotypes with a wide range of tolerance to the target metals is critical to enhance phytoremediation efficiency, as is a high accumulation capacity of metals (Aasamaa et al ).…”

Groundwater contamination with iron (Fe) and manganese (Mn) is directly related to drink water safety. It remains challenging to simultaneously remove Fe and Mn from groundwater by conventional physical and chemical methods. Willows (Salix spp.) show promise for co‐phytofiltration of Mn and Fe from groundwater. Here, a floating culture system was developed using willows for co‐phytofiltration of Mn and Fe from simulated groundwater. Genotypic differences of willows were evaluated in terms of their tolerance to and accumulation of a mixture of Fe and Mn. The results showed that the growth responses of eight genotypes significantly differed to a mixture of Fe and Mn, ranging from growth inhibition to enhancement. Tolerance index analysis further indicated wide variation in the responses of willows. Tissue‐specific analysis also revealed genotypic variation in the capacity of willows for translocation and accumulation of Fe and Mn. Compared with other genotypes, SB7 (Salix babylonica) and J842 (S. babylonica × Salix alba) demonstrated higher co‐phytofiltration potentials for Fe and Mn based on tolerance, tissue metal concentrations, and shoot metal contents. Thus, both SB7 and J842 are candidates for co‐phytofiltration of Fe and Mn from groundwater.

Fe is the fourth abundant element in the earth crust. Fe toxicity is not often discussed in plant science though it causes severe morphological and physiological disorders, including reduced germination percentage, interferes with enzymatic activities, nutritional imbalance, membrane damage, and chloroplast ultrastructure. It also causes severe toxicity to important biomolecules, which leads to ferroptotic cell death and induces structural changes in the photosynthetic apparatus, which results in retardation of carbon metabolism. However, some agronomic practices like soil remediation through chemicals, nutrients, and organic amendments and some breeding and genetic approaches can provide fruitful results in enhancing crop production in Fe‐contaminated soils. Some quantitative trait loci have been reported for Fe tolerance in plants but the function of underlying genes is just emerging. Physiological and molecular mechanism of Fe uptake, translocation, toxicity, and remediation techniques are still under experimentation. In this review, the toxic effects of Fe on seed germination, carbon assimilation, water relations, nutrient uptake, oxidative damages, enzymatic activities, and overall plant growth and development have been discussed. The Fe dynamics in soil rhizosphere and role of remediation strategies, that is, biological, physical, and chemical, have also been described. Use of organic amendments, microbe, phytoremediation, and biological strategies is considered to be both cost and environment friendly for the purification of Fe‐contaminated soil, while to ensure better crop yield and quality the manipulation of agronomic practices are suggested.
