“…Endomycorrhizal also have defense strategy to heavy metal stress, the strategy is likely to involve one of the mechanisms, including: (i) new expression of fungus gene (Cicatelli et al, 2010;Ferrol et al, 2016), (ii) metal of quarantined and deposited at extracellular (Koohi, 2014;, (iii) produce of metal binding protein (Singh, 2012;Hrynkiewicz et al, 2012), (iv) reduce of metal absorption (Karimi et al, 2011;Emamverdian et al, 2015), (v) increase efflux (Hildebrandt et al, 2007;Tiwari and Lata, 2018), (vi) formation of complexes outside the cell (Violante et al, 2010;Singh et al, 2016), (vii) release of organic acids (Adeleke et al, 2017;Mishra et al, 2017), and (viii) ligand synthesis such as polyphosphates and metallothionein (Ferrol et al, 2016;Zhan et al, 2019). Indigenous endomycorrhiza spores identified in various plant rhizosphere, obtained spores from two genera that are able to adapt in areas that have high concentrations of Fe and Mn, namely Acaulospora sp.…”

Concentrations of iron and manganese that exceed critical limits in soil and plant provide opportunities for microorganisms to become resistant. The aim of this study was to identify endomycorrhizal fungi from areas contaminated with iron and manganese for use as biostarter for phytorizoremediation programs. This research was conducted in two phases at April 2019, namely taking rhizosphere from Chromolaena odorata, Melastoma affine dan Spathoglottis plicata in Sorowako, Indonesia; and the second phase is to isolate and identify endomycorrhizal fungal spores in the Microbiology Laboratory, Center for Environmental and Forestry Research and Development in Makassar, Indonesia. The results showed that the genus Acaulospora was more dominant in areas that were contaminated with iron and manganese, and were able to adapt and survive compared to other genera.

“…This hypothesis relies on the following observations. First, it is known that structures developed by DSEs and AMFs may constitute a physical barrier that absorb and retain heavy metals and consequently lead to a reduction of metal root-to-shoot translocation, as a potential protection of shoot tissues against metal damage (Zhan et al 2019). This would be illustrated by the important abundance of Glomeromycete genes in the MS libraries.…”

“…Some herbaceous plants, such as Arabis alpina Var. parvi ora Franch, Cynodon dactylon L. Pers, Malva verticillata L., and Chenopodium ambrosioides L., were found to grow naturally around lead-zinc mine tailing areas, that may accumulate diverse heavy metals (Li et al 2019), (Zhan et al 2019), (Mayerová et al 2017), (Zhang et al 2012) Besides, Sonchus asper (L.) Hill, another annual, herbaceous dicot which probably originates from the Mediterranean Basin (Hutchinson et al 1984), is able to accumulate lead and cadmium, and is commonly distributed in Huize lead-zinc mining areas (Zu et al 2005). Collectively designed as phytoremediators, these plants, among which S. asper, may be excluders, maintaining a relatively low concentration of metals in above-ground tissues compared to roots (Baker 1981) or hyperaccumulators, with a strongly enhanced rate of metal uptake and accumulation in leaves without any toxicity symptoms (Rascio and Navari-Izzo 2011).…”

“…More generally, dark septate endophytes (DSEs), a diverse group among ascomycetes (Jumpponen and Trappe 1998), and arbuscular mycorrhizal fungi (AMFs), which belong to the phylum Glomeromycota among Mucoromycetes (Brundrett and Tedersoo 2018), establish endophytic relationships with their hosts which result in improved extraction properties of the plant (Pawlowska et al 2000;Torrecillas et al 2013). They directly participate in the soil remediation process due to their ability to degrade organic contaminants and to decrease metal toxicity, in addition to their role as promoters of plant growth and metal accumulation and translocation (Ma et al 2016;Zhan et al 2019). However, an excess of metal concentration in soils may also be detrimental to the structure and dynamics of the rhizospheric microbiota.…”

Intercropping or assistant-endophytes has been proven to promote phytoremediation capacities of hyperaccumulators and to enhance their tolerance to heavy metals (HM) stress. We initially showed that intercropping with maize improved the remediating properties of the hyperaccumulator Sonchus asper (L.) Hill grown in HM contaminated soils, accompanied by an excluder - to- hyperaccumulator switched mode of action towards lead. To characterize molecular events underlying this shift in lead extraction strategy, we conducted an RNA-Seq analysis on Sonchus roots grown in intercropping or monoculture. We show that intercropping only slightly affects the S. asper transcriptome, but dramatically impacts the expression of root associated microbial genomes. Further, intercropping triggers a severe reshaping of endophytic communities which accompanies a “root-to-shoot” transition of lead sequestration and improved phytoremediation capacities of S. asper. This study provides the clue that a unitive network of plant- microbial -plant interactions may participate to the phytoremediation abilities of hyperaccumulator plants and paves the path for innovative cultural practices aiming to cure polluted soils.

Intercropping or assistant endophytes promote phytoremediation capacities of hyperaccumulators and enhance their tolerance to heavy metal (HM) stress. Findings from a previous study showed that intercropping the hyperaccumulator Sonchus asper (L.) Hill grown in HM-contaminated soils with maize improved the remediating properties and indicated an excluder-to-hyperaccumulator switched mode of action towards lead. In the current study, RNA-Seq analysis was conducted on Sonchus roots grown under intercropping or monoculture systems to explore the molecular events underlying this shift in lead sequestering strategy. The findings showed that intercropping only slightly affects S. asper transcriptome but significantly affects expression of root-associated microbial genomes. Further, intercropping triggers significant reshaping of endophytic communities associated with a ‘root-to-shoot’ transition of lead sequestration and improved phytoremediation capacities of S. asper. These findings indicate that accumulator activities of a weed are partially attributed to the root-associated microbiota, and a complex network of plant–microbe-plant interactions shapes the phytoremediation potential of S. asper. Analysis showed that intercropping may significantly change the structure of root-associated communities resulting in novel remediation properties, thus providing a basis for improving phytoremediation practices to restore contaminated soils.
