“…Phytoremediation in the last two decades has emerged as a potential in situ technique at low-cost [ 11 ] but, despite the excellent results obtained in the lab by numerous scientists, the scientific literature documenting its application in the field is still rather scanty [ 40 ]. Anyway, some of these report the effect of P. vittata , used in the field [ 4 , 43 , 44 , 45 ], or as an intercropping plant [ 46 , 47 ]. However, none of these papers focused on the phytoremediation activity of AMF inoculated fern.…”

Phytoremediation is a promising green technique for the restoration of a polluted environment, but there is often a gap between lab and field experiments. The fern, Pteris vittata L., can tolerate a high soil arsenic concentration and rapidly accumulate the metalloid in its fronds. Arbuscular mycorrhizal fungi (AMF) are mutualistic fungi that form a symbiosis with most land plants’ roots, improve their growth, and induce stress tolerance. This paper reports the results obtained using P. vittata inoculated with AMF, to extract Arsenic (As) from an industrial site highly contaminated also by other pollutants. Two experiments have been performed. In the first one, AMF colonized ferns were grown for two years under controlled conditions in soil coming from the metallurgic site. Positive effects on plant health and As phytoextraction and accumulation were detected. Then, considering these results, we performed a three year in situ experiment in the industrial site, to assess the remediation of As at two different depths. Our results show that the colonization of P. vittata with AMF improved the remediation process of As with a significant impact on the depth 0–0.2 m.

“…Intercropping of P. vittata with other cash crops has become a scenario to sustainably reuse the contaminated soil. This process can gradually clean the environment and at the same time bring in economic benefits (Wan et al, 2017b;Ma et al, 2018). If the hypothesis can be confirmed, intercropping with P. vittata may act as a biocontrol method for insecticides.…”

The development of an effective and green bioinsecticide is a research hotspot. This study demonstrated the possibility of using an arsenic (As) hyperaccumulator as a bioinsecticide. When the As concentration in the Pteris vittata fronds exceeded 138 mg kg -1 , the larva of the hawk moth (Theretra clotho) displayed apparent preference to lower-As-concentration P. vittata fronds. The As concentration in the larva body was as high as 850 mg kg -1 . Such high concentration of As in the larva body might have been the case that T. clotho lacks a process to exclude As. The larval frass showed an As concentration of only 1%-4% of that in the larva body. The predominant As species in the larva body and frass was As(III)-SH. The percentage of As(III)-SH was slightly higher in the frass than that in the larval body. Chelation with thiols may be a universal detoxification mechanism for As in both plants and insects. In general, the adoption of P. vittata as a bioinsecticide should be feasible. However, the exact processes to achieve this goal still need further study. The mechanism of different animals to detoxify As is another interesting research topic.

“…The optimized read sequence numbers were uneven. Each sample was randomly reduced to the size using the MOTHUR basing to the smallest read number (24,712). The genetic distances of 3% OTUs were identified and a total of 11,930 OTUs were acquired from the samples ranging 5848 from the interplant Lolium perenne with garlic, 6082 single planting Lolium perenne, respectively covering 99% in each of the samples.…”

“…Garlic is known to be for its ability to resist biotic and abiotic environmental stresses like bacterial, viral and oxidative stresses 22 and have a potential to persist against some heavy metals such as cadmium. Garlic as a spice plant was chosen as an intercrop plant with hyper-accumulator for its effect on soil microbial activities of heavy metals in soil 23,24 . The inter-planting is concerned, this arena has attracted the attention of soil scientists to remediate the soil contamination of heavy metals 25,26 .…”

Heavy metals are naturally occurring elements that have a high atomic weight and let out in the environment by agriculture, industry, mining and therapeutic expertise and thrilling amassing of these elements pollutes the environment. In this study we have investigated the potential of garlic interplanting in promoting hyper accumulation and absorption of heavy metals to provide a basis for phytoremediation of polluted land. Monoculture and inter-plantation of garlic were conducted to investigate the absorption of cadmium and lead contamination in the land. A group of experiments with single planting (monoculture) of Lolium perenne, Conyza canadensis and Pteris vittata as accumulators were used. The results have shown that garlic has a potential as a hyper accumulate and absorb heavy metals. It was found that the accumulation of Cd and Pb was much higher with inter-planting. Garlic boosts up the absorption of heavy metals in Lolium perenne of Cd 66% and Pb 44% respectively. The Inter-planting of garlic with Pteris vittata promotes the Cd 26% and Pb 15%. While the maximum accumulation of Lead 87% and Cadmium 77% occurred in Conyza canadensis herb plant. The bacterial diversity in the soil was analyzed for each experimental soil and was found that the Proteobacteria, Acidobacteria, Actinobacteria, Firmicutes, and Planctomycetes were commonly abundant in both single planting (monoculture) of ryegrass and interplanting ryegrass with garlic habitats. Variances were observed in the bacterial floral composition of single (monoculture) and intercropping (interplant) soils. Relative abundance of bacterial taxa revealed that the proportion of Proteobacteria, Acidobacteria, and Actinobacteria in the inter-planting group was slightly higher, while Firmicutes and Planctomycetes were low. This study provides the evidence to control the heavy metals contaminated soils with weed species. Growth promotion and heavy metal uptake of neighboring plants proved the specific plant-plant and plant-microbial associations with garlic plants. This inter-planting strategy can be used to improve heavy metal absorption.
