“…The results of As bioaccumulation and translocation confirmed P. cretica ‘Albo-lineata’ as an As-hyperaccumulating fern. Similar results were previously observed [ 21 , 23 , 28 , 37 , 38 ].…”

“…Plants adapt to environmental changes by regulating their development and growth [ 1 ], which leads to decreased plant growth as the first visible symptom of stress [ 30 ]. Arsenic is considered phytotoxic and is expected to have adverse effects on plant growth [ 26 ] that was previously observed for the growth of S. oleracea [ 18 , 30 , 40 , 42 ] and P. cretica [ 28 , 37 ]. Similar to these findings, in our study, shoot and root dry biomass of P. cretica and S. oleracea were also affected by As concentration ( Figure 2 A,B).…”

“…Compared to non-As-hyperaccumulators, As-hyperaccumulators had less of a tendency for complex formation [ 13 , 26 , 27 ]. It has been shown that in tolerant ferns, most As(V) is reduced by ACR2 reductase to As(III), which is subsequently transported by ACR3 transporter to the leaves [ 28 ].…”

Arsenic is a ubiquitous toxic element that can be accumulated into plant parts. The present study investigated the response of Pteris cretica and Spinacia oleracea to As treatment through the analysis of selected physiological and metabolic parameters. Plants were grown in pots in As(V) spiked soil (20 and 100 mg/kg). Plants’ physiological condition was estimated through the determination of elements, gas-exchange parameters, chlorophyll fluorescence, water potential, photosynthetic pigments, and free amino acid content. The results confirmed differing As accumulation in plants, as well as in shoots and roots, which indicated that P. cretica is an As-hyperaccumulator and that S. oleracea is an As-root excluder. Variations in physiological and metabolic parameters were observed among As treatments. Overall, the results revealed a significant effect of 100 mg/kg As treatment on the analysed parameters. In both plants, this treatment affected growth, N, Mg, S, Mn, and Zn content, as well as net photosynthetic rate, chlorophyll fluorescence, and total free amino acid content. In conclusion, the results reflect the similarity between P. cretica and S. oleracea in some aspects of plants’ response to As treatment, while physiological and metabolic parameter changes related to As treatments indicate the higher sensitivity of S. oleracea.

“…In contrast to these results, Zemanová et al (2022) indicated no statistically significant differences in the root yield of P. cretica grown on As-contaminated soils compared with the control. Popov et al (2021) confirmed no significant changes in the roots of this fern with an As dose of 100 mg/kg soil, while root yield on soil contaminated with a higher As dose (250 mg/kg soil) was significantly reduced. The correlations of root biomass yield with As (r = 0.95, P < 0.001), Cd (r = 0.94, P < 0.001), Pb (r = 0.95, P < 0.001), and Zn (r = 0.94, P < 0.001) were determined.…”

Soil contamination with toxic elements affects soil microbiology and causes changes in the interactions between plants and microorganisms. It also significantly affects soil characteristics, plant growth, vegetation type, and agricultural land production (Wahsha et al. 2017, Zeng et al. 2019, Aponte et al. 2020a, Majumder et al. 2022. The accumulation of toxic elements by plants results in entry into the food chain, which then becomes hazardous to human health (Pande et al. 2022).Soil enzymes produced extracellularly by microorganisms are key participants in soil nutrient cycles and functional sustainability. They are sensitive to changes in the soil environment, such as contamination by toxic elements (Wahsha et al. 2017, Nkongolo and Narendrula-Kotha 2020, Cui et al. 2021, Majumder et al. 2022. Due to these characteristics, they can be used as biological indicators for evaluating soil health (Aponte et al. 2020b, Skowrońska et al. 2020.The mineralisation of carbon (C) in the soil is crucial for soil quality, as it increases soil fertility. However, this is influenced by plant root exudation, microbial activities, and soil pH (Yu et al. 2021). The zone of plant roots also influences the activity and

“…Although model plants like Arabidopsis possess similar As (V)-reductases such as AtHAC1 , their ability to specifically reduce As is limited, resulting in an inability to accumulate significant As concentrations [ 91 , 130 ]. Furthermore, PvACR2 and PvACR3 encoding for an As (V)-reductase and As (III)-transporter, respectively, participates in the translocating and sequestering of As in shoot tissues [ 131 ]. The activation of the ACR gene has been associated with the conversion of As (V) to As (III), and the suppression of this gene has been demonstrated to result in the increased accumulation of As (V) in Arabidopsis [ 132 ].…”
