Arsenic detoxification in two populations of Borreria verticillata (Rubiaceae) with differential tolerance to the metalloid
TLDR
It is verified that besides the differences in P metabolism that have been reported in the literature, plants from the CS are more As-tolerant due to their higher efficiency for As detoxification, and are therefore more well suited for the revegetation of As-contaminated areas.
Differential Arsenic-Induced Membrane Damage and Antioxidant Defence in Isolated Pinna Segments of Selected Fern Species from Western Himalaya
TLDR
The activities of antioxidant enzymes, superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX) were markedly altered due to As treatment in a species-specific manner pointing to a role of antioxidant defence in differential response and thereby tolerance of the concerned ferns to As.
Intercropping efficiency of four arsenic hyperaccumulator Pteris vittata populations as intercrops with Morus alba
TLDR
Root overlap and aboveground morphological parameters are the key factors determining intercropping efficiency among P. vittata populations, thus depleting As in the rhizosphere and lowering As risk.
Morphological characteristics and accumulation of arsenic in Argyrochosma formosa (Liebm.) Windham developed in a highly contaminated site with arsenic in Matehuala, SLP, México
TLDR
The data suggest that A. formosa is an arsenic-tolerant species and propose it for phytoremediation on contaminated sites with As concentrations similar to that of the studied location.
Absorption of Hazardous Pollutants by a Medicinal Fern Blechnum orientale L.
TLDR
Uptake of pollutants via stomata might be the main reason causing the significant accumulation of hazardous pollutants in the fronds of B. orientale, and large-scale systematical survey and intensive monitoring on pollutants should be necessarily strengthened.
Arsenic Hyperaccumulator Fern Pteris vittata: Utilities for Arsenic Phytoremediation and Plant Biotechnology
TLDR
Research indicates that brake fern could be a source of genes that could inform us about how plants adapt to abiotic stress factors such as high temperature stress and drought that have oxidative stress as a component, and can be expected to be valuable for improving crops for increased tolerance to stress.
Novel Genes of Hyperaccumulator Ferns in Arsenic Tolerance, Uptake, and Metabolism: Implications for Crop Improvement
TLDR
Research in this area is summarized to point out how the fern genes could be utilized to engineer plants with little ability to take up and accumulate arsenic for arsenic phytoremediation and to engineer crop plants to have improved tolerance to abiotic stress, thus potentially improving soil remediation and food security.

Characteristics of Arsenic Accumulation by Pteris and non-Pteris Ferns
TLDR
The ability of P. vittata to translocate arsenic from the roots to the frond, reduce arsenate to arsenite in the fronds, and maintain high concentrations of phosphate in the roots all contributed to its arsenic tolerance and hyperaccumulation.
Arsenic hyperaccumulation by different fern species
TLDR
This study identified three new species of As hyperaccumulators in the Pteris genus and suggests that Ashyperaccumulation is a constitutive property in P. vittata, which was the first identified arsenicHyperaccumulator.
Arsenic accumulation by ferns: a field survey in southern China
TLDR
The association between Fe accumulation and As accumulation and tolerance in these ferns indicates the unique role of Fe in As-hyperaccumulation.

TLDR
This study is the first to report members of the Pteris genus that do not hyperaccumulate arsenic, Pter is straminea and tremula, as this character is not exhibited by primitive ferns or their allies.
ARSENIC TOLERANCE, ACCUMULATION AND ELEMENTAL DISTRIBUTION IN TWELVE FERNS: A SCREENING STUDY
TLDR
This is the first known report of ferns that are sensitive to As, yet are As hyperaccumulators, and may be useful for phytoremediating As contaminated sites because of their ability tohyperaccumulate and tolerate high As levels.
Antioxidant responses of hyper-accumulator and sensitive fern species to arsenic.
TLDR
Arsenic accumulation increased with an increase in arsenic concentration in the growth medium, the most being found in P. vittata fronds showing no toxicity symptoms, and responded differentially to arsenic exposure in terms of anti-oxidative defence.
