• Legume– Rhizobium Symbioses as a Tool for Bioremediation of Heavy Metal Polluted Soils (2011, background): “vittata, arsenate is taken up through the phosphate transporters, reduced to arsenite, and sequestered in the fronds primarily as As(III) (Wang et al. 2002).”
• The nature of arsenicphytochelatin conplexes in Holcus lanatus and Pteris cretica (2004, background): “Lombi et al. (2002) have produced evidence that As is stored primarily in the vacuole of P. vittata, and Wang et al. (2002) have shown that this As is primarily As(III), with some As(V).”
• Root exudates and arsenic accumulation in arsenic hyperaccumulating Pteris vittata and non-hyperaccumulating Nephrolepis exaltata (2004, positive): “These characteristics of As hyperaccumulation by Chinese Brake fern were similar to those of Wang et al. (2002), and corroborate the results by other researchers (Komar, 1999; Ma et al., 2001) who characterized the As hyperaccumulation of the fern grown in soils.”

• Remediation of Heavy Metal Contaminated Soils: Phytoremediation as a Potentially Promising Clean-Up Technology (2009, background): “…terrestrial plants, the brake fern Pteris vittata, which can produce a relatively large biomass in favourable climates; it can accumulate up to 22,000 mg As kg−1 in the frond (dry weight), although phytotoxicity occurs when shoot arsenic level is higher than ca. 10,000 mg kg−1 (Wang et al., 2002).”
• Bacteria and fungi can contribute to nutrients bioavailability and aggregate formation in degraded soils. (2016, neutral): “Presence of such heavy metals encourages the bacteria to produce siderophores which chelate the metal to increase Fe availability in the rhizosphere of these soils (Wang et al., 2002).”
• Arsenic uptake and toxicity in plants: integrating mycorrhizal influences (2010, background): “This point is important seeing that while uptake of As(V) and Pi involves competition for common transporters, As(III) and Pi do not compete (Abedin et al. 2002b; Wang et al. 2002).”
• The roles of membrane transporters in arsenic uptake, translocation and detoxification in plants (2020, background): “…in As hyperaccumulator Pteris vittata The As hyperaccumulator Pteris vittata is efficient at As(V) uptake and phosphate utilization (Han et al., 2017; Ma et al., 2001; Wang et al., 2002), but the knowledge of the transporters involved in uptake and transport of phosphate/As(V) is still limited.”
