“…The on-site soil medium had a pH of 7.3, top soil was 6.8 and river sand medium was 6.7. These were also the pH range observed by Wan et al (2010) where spores of P. vittata germinated, though germination percentage was low compared to media with high pH. The same pH range was observed to be optimal in Anemia mexicana and A. phyllitidis (Nester and Coolbaugh, 1986).…”

Pteris vittata has been reported to be a hyperaccumulator of arsenic, and therefore useful in phytoremediation to clean-up arsenic-contaminated soils. Although factors for successful germination of spores have been identified, but information concerning the whole range of steps involved in mass propagating the fern is lacking.Thus, the study was aimed to develop a propagation protocol using spores to produce large number of seedlings.We implemented descriptive research methodologies such as observation and documentation of fern propagation activities in the nursery and conducted experiment following completely randomized designed with three replications. Here, we show that seedlings of Pteris vittata were successfully produced and protocol for its propagation is described.

The difficulty of target microorganisms surviving and adapting to field environments is an important reason for the poor effect of field inoculation tests ( Wan et al, 2009 ). The results of this study show that in field environments, the interaction between P .…”

Arsenic contamination causes numerous health problems for humans and wildlife via bioaccumulation in the food chain. Phytoremediation of arsenic-contaminated soils with the model arsenic hyperaccumulator Pteris vittata provides a promising way to reduce the risk, in which the growth and arsenic absorption ability of plants and the biotransformation of soil arsenic may be greatly affected by rhizosphere microorganisms. However, the microbial community composition in the rhizosphere of P. vittata and its functional role in arsenic phytoremediation are still poorly understood. To bridge this knowledge gap, we carried out a field investigation and pot experiment to explore the composition and functional implications of microbial communities in the rhizosphere of four P. vittata populations with a natural arsenic contamination gradient. Arsenic pollution significantly reduced bacterial and fungal diversity in the rhizosphere of P. vittata (p < 0.05) and played an important role in shaping the microbial community structure. The suitability of soil microbes for the growth of P. vittata gradually decreased following increased soil arsenic levels, as indicated by the increased abundance of pathogenic fungi and parasitic bacteria and the decrease in symbiotic fungi. The analysis of arsenic-related functional gene abundance with AsChip revealed the gradual enrichment of the microbial genes involved in As(III) oxidation, As(V) reduction, and arsenic methylation and demethylation in the rhizosphere of P. vittata following increased arsenic levels (p < 0.05). The regulation of indigenous soil microbes through the field application of fungicide, but not bactericide, significantly reduced the remediation efficiency of P. vittata grown under an arsenic contamination gradient, indicating the important role of indigenous fungal groups in the remediation of arsenic-contaminated soil. This study has important implications for the functional role and application prospects of soil microorganisms in the phytoremediation of arsenic-polluted soil.

“…Water losses due to evapotranspiration were replaced daily with Milli-Q water and replaced every two weeks. The plants were raised in a growth chamber at ~70% relative humidity, 25 °C day/night temperature, and a 16 h light and 8 h darkness (Wan et al 2010). When the new fronds and leaves were emerging, the conditioned plants were used in Experiments 2.2-2.4.…”

“…For example, P de ciency induces citric acid exudations in white lupin (Lupinus albus) to manage P de ciency (Cheng et al 2011), another study suggested that Oat (Avena sativa) roots also showed citric acid exudation in response to P de ciency (Wang et al 2016) while one of a recent study suggested that Chinese brake fern (Pteris vittata) plant release phytic acid to cope with P de ciency (Fu et al 2017). Chinese brake fern (Pteris vittata) is a widely distributed plant in Asia, Europe, Africa, Australia, can be grow in different environments (Wan et al 2020), with a high yield of about 36 ton per hectare (Song et al 2019). Besides, Pteris vittata (P. vittata) is also native to soils (tropical) of low nutrient status that contain mostly unavailable organic and inorganic P .…”

Phosphorus (P) is limiting nutrient in soil system. The P availability in soil strongly depend on Iron (Fe) speciation. Colloidal iron phosphate (FePO 4coll ) is an important phosphorus (P) fraction in soil solution that carry P from soil to water bodies. This study tested the hypothesis that phytate exudation by Pteris vittata (P. vittata) can dissolve FePO 4coll that leads to release of P and Fe. The phytate exudation in P. vittata increased from 434−2136 mg kg −1 as the FePO 4coll concentration increased from 0−300 mM. The total P in P. vittata tissue increased from 2.88 to 8.28 g kg −1 , the trichloroacetic acid P fractions (TCA fractions) were: inorganic P (0.86-5.10 mg g −1 ), soluble organic P (0.25-0.87 mg g −1 ), and insoluble organic P (0.16-2.03 mg g −1 ) which leads to higher biomass as FePO 4coll increased from 0−300 mM.The linear regression analysis showed that FePO 4 solubilizing activity has a positive correlation with TP, TCA P fractions in P. vittata, TP in growth media, and root exudates. This study shows that phytate exudation dissolved the FePO 4coll due to the chelation effect of phytic acid on Fe, and due to the high Fe-P solubilizing activity in root exudates of P. vittata.
