Background. Nelumbo nucifera Gaertn stem (Hegeng [HG]) is a traditional Chinese medicine that is used to treat mental symptoms in East Asia. However, scientific evidence is generally lacking to support this traditional claim. Aim of the Study. This study’s aim is to investigate the antidepression effect of HG and to further explore the possible molecular mechanisms that are involved in its actions. Materials and Methods. HG aqueous extract was administered intragastrically for 21 days after the chronic unpredictable mild stress (CUMS) procedure, and its effect on memory, learning, and emotion was assessed using animal behavioral tests. HG aqueous extract was characterized using HPLC. Immunofluorescence was used to measure the neural cell-adhesion molecule (NCAM) and growth-associated protein-43 (GAP-43) expression. Results. Depression-like behaviors increased in the CUMS group compared with the control (CON) group, while they were reduced in the high-dose HG (H-HG) and fluoxetine (FLU) groups (p<0.05). Additionally, NCAM and GAP-43 expression was reduced in the CUMS group compared with the CON group, but it increased in the H-HG and FLU groups (p<0.05). Conclusions. These findings show the potential antidepressant effects of HG through mechanisms involving regulation of NCAM and GAP-43. This provides a new theoretical basis for its potential application as an antidepressant-like agent.

“…Some herbaceous plants such as Arabis alpina Var. parviflora Franch, Cynodon dactylon L. Pers, Malva verticillata L. and Chenopodium ambrosioides L. grow naturally around lead-zinc mine tailing areas and accumulate different heavy metals (Li et al 2019;Zhan et al 2019;Mayerová et al 2017;Zhang et al 2012). Sonchus asper (L.) Hill is an annual herbaceous dicot which probably originates from the Mediterranean Basin (Hutchinson et al 1984).…”

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.

“…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).…”

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.
