“…17 Meanwhile, intercropping with Cd-accumulators Helianthus annuus, Cosmos sulphureus, Cosmos bipinnata, and Impatiens balsamina also reduce the Cd uptake in grapevine. 18 Other intercropping combinations, such as Kummerowia striata intercropped with Brassica chinensis, Sedum plumbizincicola intercropped with Luffa cylindrical, and Tagetes patula intercropped with tomato, all decrease the Cd content in edible parts of plants. [19][20][21] These studies show that hyperaccumulators intercropped with non-hyperaccumulators is an effective measure to improve phytoremediation and agricultural production efficiencies.…”

Intercropping with hyperaccumulators can decrease the cadmium (Cd) uptake in non‐hyperaccumulators, but there are few studies on fruit trees. To decrease the Cd uptake in fruit trees, three Cd‐hyperaccumulator Solanum species (Solanum nigrum var. humile, Solanum americanum, and Solanum photeinocarpum) were intercropped with Amygdalus persica seedlings, and the effects of intercropping with Solanum species on the Cd and nutrient uptakes in A. persica were studied. Intercropping with S. nigrum var. humile increased the biomass of A. persica, while intercropping with S. americanum and S. photeinocarpum decreased that. Intercropping with A. persica increased the biomass of three Solanum species. Intercropping promoted the phosphorus (P) and potassium (K) uptakes in both A. persica and Solanum species. For Cd uptake, intercropping reduced the Cd uptake in A. persica and enhanced the Cd uptake and extraction in Solanum species. Correlation analysis showed that the Cd and K had antagonistic effect in aboveground of A. persica. Therefore, A. persica intercropped with Solanum species can reduce the Cd uptake in A. persica and improve the phytoremediation abilities of Solanum species, which is suitable for the Cd‐contaminated peach orchard.

“…However, hyperaccumulators have limitations such as slow growth rate, low biomass production and low restoration rate (Maestri et al 2010). Therefore, studies should explore strategies for combining hyperaccumulators with other measures to improve efficiency of heavy metal remediation (Chen et al 2019).…”

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.

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.
