“…So, the basic properties of those two phytoextraction strategies of metals from soils are illustrated as followed in Table 2. In addition, the analysis of the Table 2 content and based on some of other's investigations give birth to a fundamental conclusion summarized on the fact that the natural metal-accumulating capacity seem to be the most one because of the negative repercussion of the chemically enhanced phytoextraction method [26][27][28].…”

In these last decades, excessive metal concentration pose serious contamination in soils. Therefore, it is urgent to develop and adopt a new strategy and technology to remove soil contaminants. Here, the phytoextraction was considered as a recently developed approach to clean up metal-polluted soils in that the plants are used to translocate the toxic metals from the contaminated soils. Therefore, this mini-review provides a perfection of recent knowledge related to the heavy metal phytoextraction from soils and their accumulation in plants. It has been reported that EDTA enhances the availability of heavy metal to plants and thus increases the accumulation in their shoots. In addition, fundamental and basic advancement has been made on the molecular aspects and the physiological regarding tolerance and metals phytoaccumulation in plants. A multidisciplinary strategy is warranted to make phytoextraction a plausible trade technology to remediate metal-polluted soils. Hence, the purpose is to integrate soil-related and biological progress to suggest research needs and future direction.

“…mitigated Mn-induced oxidative stress by reducing malonaldehyde content and antioxidant enzyme activities in leaves [ 163 ]. Kumar et al [ 164 ] found that the isolate Pseudomonas lurida EOO26 presented multi-metal tolerance, drought resistance and plant growth-promoting attributes, and the inoculation with EOO26 increased Cu uptake by 8.6 times in roots and 1.9 times in leaves of Helianthus annuus than uninoculated individuals. Microorganisms can also drive redox reactions to change the valence of heavy metals and reduce their biological toxicity [ 109 ].…”

Medicinal plants (MPs) are important resources widely used in the treatment and prevention of diseases and have attracted much attention owing to their significant antiviral, anti-inflammatory, antioxidant and other activities. However, soil degradation, caused by continuous cropping, excessive chemical fertilizers and pesticide residues and heavy metal contamination, seriously restricts the growth and quality formation of MPs. Microorganisms, as the major biota in soil, play a critical role in the restoration of the land ecosystem. Rhizosphere microecology directly or indirectly affects the growth and development, metabolic regulation and active ingredient accumulation of MPs. Microbial resources, with the advantages of economic efficiency, harmless to environment and non-toxic to organisms, have been recommended as a promising alternative to conventional fertilizers and pesticides. The introduction of beneficial microbes promotes the adaptability of MPs to adversity stress by enhancing soil fertility, inhibiting pathogens and inducing systemic resistance. On the other hand, it can improve the medicinal quality by removing soil pollutants, reducing the absorption and accumulation of harmful substances and regulating the synthesis of secondary metabolites. The ecological and economic benefits of the soil microbiome in agricultural practices are increasingly recognized, but the current understanding of the interaction between soil conditions, root exudates and microbial communities and the mechanism of rhizosphere microecology affecting the secondary metabolism of MPs is still quite limited. More research is needed to investigate the effects of the microbiome on the growth and quality of different medicinal species. Therefore, the present review summarizes the main soil issues in medicinal plant cultivation, the functions of microbes in soil remediation and plant growth promotion and the potential mechanism to further guide the use of microbial resources to promote the ecological cultivation and sustainable development of MPs.

Endophytic Microbes Are Tools to Increase Tolerance in Jasione Plants Against Arsenic Stress

Seed microbiota is becoming an emergent area of research. Host plant microbial diversity is increasingly well described, yet relatively little is known about the stressors driving plant endomicrobiota at the metaorganism level. The present work examines the role of horizontal and vertical transmission of bacterial microbiota in response to abiotic stress generated by arsenic. Horizontal transmission is achieved by bioaugmentation with the endophyte Rhodococcus rhodochrous, while vertical transmission comes via maternal inheritance from seeds. To achieve this goal, all experiments were conducted with two Jasione species. J. montana is tolerant to arsenic (As), whereas J. sessiliflora, being phylogenetically close to J. montana, was not previously described as As tolerant. The Jasione core bacterial endophytes are composed of genera Pseudomonas, Ralstonia, Undibacterium, Cutibacterium, and Kocuria and family Comamanadaceae across different environmental conditions. All these operational taxonomic units (OTUs) coexisted from seeds to the development of the seedling, independently of As stress, or bioaugmentation treatment and Jasione species. R. rhodochrous colonized efficiently both species, driving the endomicrobiota structure of Jasione with a stronger effect than As stress. Despite the fact that most of the OTUs identified inside Jasione seeds and seedlings belonged to rare microbiota, they represent a large bacterial reservoir offering important physiological and ecological traits to the host. Jasione traits co-regulated with R. rhodochrous, and the associated microbiota improved the host response to As stress. NGS-Illumina tools provided further knowledge about the ecological and functional roles of plant endophytes.
