“…The amount of elements (Ca, Mg and K) taken up by the root fragment placed in the Al substrate was higher, which was found thanks to the compounds labelled stable isotopes. The toxicity of high doses of Al 3+ which was treated in one part of the eucalyptus roots is neutralised by adding phosphorus ions in the other part (Kang et al 2020). The SRS method revealed that the toxic concentrations of zinc (Zn) for part of the willow root (Salix matsudana; Salicaceae) result in a greater allocation of carbon to the zone free of elevated concentrations of this element (Palm et al 2021).…”

The split-root system technique has been used to analyse plant biology for several decades, but woody plants have not received enough attention in this experimental approach. Historically, several methods have been developed, ranging from the simplest method of dividing a root into two parts and placing them in separate containers to more complex methods, such as grafting a second root from another plant. Each method has advantages and disadvantages that determine the goals of the experiment. Thus far, research using the split-root system has covered only 62 species of woody plants, mainly to investigate the water shortage effect on water acquisition. Many studies have also considered the significance of functional root-system diversity for plant fertilisation, which allows a better understanding of ion transport regulation mechanisms and some anatomical and functional features of woody plants. Ion uptake and transport have been studied frequently using isotope labelling. The split-root system method also offers interesting possibilities for studying the interactions of plants with other organisms. For example, this method was used to study root colonization strategies by mycorrhizal fungi. The comprehensive analysis of the split-root system technique in this review provides fine-scale information on the future concepts needed to study root-system biology, as the ability of roots to play a range of functions in the plant remains largely untested.

“…Under acidic conditions, the adsorption ability of soil on Ca 2+ , Mg 2+ , K + and NH 4 + decreases, and they are more easily lost with water, resulting in a decline in soil fertility [ 88 ]. Soil acidification impairs phosphorus availability by driving the dissolution of aluminum and iron ions, which will combine with PO 4 3− to form insoluble precipitation [ 89 , 90 ]. Babourina et al [ 91 ] indicated that low pH induced strong H + influx, depolarized plasma membrane potential and led to a significant net K + efflux from the root cell of plants.…”

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.
