“…The symbiotic association between the endophytic fungus P. indica and plants offers a promising approach to enhance plant traits and remediate heavy metal-contaminated soils. Studies demonstrated that P. indica colonization improves arsenic tolerance by reducing hydrogen peroxide accumulation while increasing glutathione and proline levels in arsenic-treated plants and immobilizing arsenic in roots while facilitating iron transport to the leaf tips in rice [23,24]. Furthermore, P. indica induces the up-regulation of glyoxalase I (Gly I) and glyoxalase II (Gly II) genes, optimizes the redox status of the ascorbic acid-glutathione (AsA-GSH) cycle, and reduces the content of malondialdehyde (MDA) and methylglyoxal (MG), consequently enhancing arsenic tolerance in rice seedlings [24].…”

Piriformospora indica (Serendipita indica), a mycorrhizal fungus, has garnered significant attention in recent decades owing to its distinctive capacity to stimulate plant growth and augment plant resilience against environmental stressors. As an axenically cultivable fungus, P. indica exhibits a remarkable ability to colonize varieties of plants and promote symbiotic processes by directly influencing nutrient acquisition and hormone metabolism. The interaction of plant and P. indica raises hormone production including ethylene (ET), jasmonic acid (JA), gibberellin (GA), salicylic acid (SA), and abscisic acid (ABA), which also promotes root proliferation, facilitating improved nutrient acquisition, and subsequently leading to enhanced plant growth and productivity. Additionally, the plant defense system was employed by P. indica colonization and the defense genes associated with oxidation resistance were activated subsequently. This fungus-mediated defense response elicits an elevation in the enzyme activity of antioxidant enzymes, including superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT), and, finally, bolsters plant tolerance. Furthermore, P. indica colonization can initiate local and systemic immune responses against fungal and viral plant diseases through signal transduction mechanisms and RNA interference by regulating defense gene expression and sRNA secretion. Consequently, P. indica can serve diverse roles such as plant promoter, biofertilizer, bioprotectant, bioregulator, and bioactivator. A comprehensive review of recent literature will facilitate the elucidation of the mechanistic foundations underlying P. indica–crop interactions. Such discussions will significantly contribute to an in-depth comprehension of the interaction mechanisms, potential applications, and the consequential effects of P. indica on crop protection, enhancement, and sustainable agricultural practices.

“…The edible part of rice contains a lot of arsenic ( Meharg, 2004 ; Dolphen and Thiravetyan, 2019 ). When wheat and some vegetables are planted in arsenic contaminated farmland, a large amount of arsenic is accumulated in their edible parts ( Saeed et al., 2021 ; Shukla et al., 2022 ). However, we emphasize that the synthetic biological chassis carrier for phytoremediation should not use existing crops to ensure that the products produced do not enter the food chain.…”

High concentrations of heavy metals in the environment will cause serious harm to ecosystems and human health. It is urgent to develop effective methods to control soil heavy metal pollution. Phytoremediation has advantages and potential for soil heavy metal pollution control. However, the current hyperaccumulators have the disadvantages of poor environmental adaptability, single enrichment species and small biomass. Based on the concept of modularity, synthetic biology makes it possible to design a wide range of organisms. In this paper, a comprehensive strategy of “microbial biosensor detection - phytoremediation - heavy metal recovery” for soil heavy metal pollution control was proposed, and the required steps were modified by using synthetic biology methods. This paper summarizes the new experimental methods that promote the discovery of synthetic biological elements and the construction of circuits, and combs the methods of producing transgenic plants to facilitate the transformation of constructed synthetic biological vectors. Finally, the problems that should be paid more attention to in the remediation of soil heavy metal pollution based on synthetic biology were discussed.

“…S. indica can not only increase soil urease and phosphatase activities to improve plant utilization efficiency of soil nutrients but also increase soil catalase to relieve the toxic effects of hydrogen peroxide [14]. Moreover, S. indica can accumulate As in the plant roots and restrict their movement to aerial parts [15]. Therefore, we hope that with the help of S. indica, Cd can be fixed in the soil and not easily absorbed by plants; even if plants absorb Cd, it can be accumulated in the non-edible parts, so that the edible parts of plants have no or low Cd concentrations.…”

Background Plants-microbial technology has been regarded as a popular and applied new technique for the remediation of cadmium (Cd) polluted soils. Methods Therefore, a pot experiment was conducted to explore the effect of Serendipita indica (S. indica) on soybean growth and the soil enzyme activities, pH and Cd chemical fractions in the soil in 0, 3, 6, and 9 mg·kg−1 Cd concentrations. Results Results reflected that compared to uninoculated treatment, S. indica inoculation can still enhance the dry weight (66.57%) and shoot length (90.35%) and promote the net photosynthesis rate (72.18%), transpiration ratio (80.73%), and stomatal conductance (119.05%) of soybean under 9 mg·kg−1 Cd stress. Furthermore, the soil pH, phosphatase (116.39%), and catalase (4.17%) activities in the S. indica treatments were increased under 3 mg·kg−1 Cd concentration. Meanwhile, S. indica could shift Cd from exchangeable fraction to other stable fractions, primarily decreased Cd contamination degree/risk in 6 mg·kg−1 Cd concentration. Conclusions This work suggested that S. indica may be a potential biotechnology for low Cd-contaminated farmland, S. indica can not only alleviate Cd phytotoxicity and promote plant growth but also improve soil quality in Cd-contaminated soils.
