“…It is known that FLC and PAHs cause in plants the oxidative stress accompanied by the increased production of ROS [Liu et al 2018b;Shen et al 2019a]. ROS production in roots can alter the root anatomy and can cause the formation of the intercellular spaces via the programmed cell death [Svobodníková et al 2020], which could be also initiated with the increased level of ethylene [Kummerová et al 2010;Váňová et al 2011]. In our study we did not observe the formation of lysigenous intercellular spaces in the roots (or stems) of experimental plants, as well as no significantly higher levels of ethylene in roots (data not presented) but about the oxidative stress could report the higher levels of malondialdehyde analysed in leaves and presented in previous study by Lónová et al [2023].…”

Despite current efforts to minimize the impact of industry on ecosystems, the environment is polluted by a range of foreign substances, that can have a negative impact on the living organisms. Examples of widely studied substances are polycyclic aromatic hydrocarbons (PAHs) and recently, substances commonly used in conventional agriculture.In our study we focused on the morphology and anatomy of the vegetative organs of pea plants treated with the active substance of herbicides, flurochloridone (FLC), in concentration representing the residual amount in the soil (5 µM), and PAH fluoranthene (FLT) in concentration representing the middle to high environmental load (5 µM). During the long-term cultivation in nutrient solutions modified by the mentioned pollutants, the growth parameters of roots and shoots were observed in the three growth phases (4 and 8 fully developed leaves and the flowering phase). The growth parameters and observation of the morphology were supplemented with root and stem anatomical analysis using the transverse cross-sections. Both xenobiotics caused the decrease in the biomass production, while the more significant inhibition of growth, compared with control plants, was detected in FLC-treated plants, where the root system was reduced up to 75% and growth parameters of the shoots were reduced about more than 50%. The decrease in root biomass production was accompanied by changes in root branching. FLT treatment caused milder growth inhibition, it was observed about 50% reduction of the root system induced by the shortening of the main and lateral roots. Less pronounced, was also the decrease in stem length caused by FLT. Similar information was obtained about the different degrees of effect of FLC and FLT using anatomical analysis. Both studied substances increased the main root diameter accompanied with increase of the average number of the primary cortex layers. Their influence also caused the more intensive formation of exodermis. Changes in anatomical architecture were also observed in stem, where the FLC treatment changed the arrangement of the vascular bundles and decreased their average number. Our elementary morpho-anatomical study suggests that FLC despite its trace concentration could be more detrimental to plants than FLT, known for its harmful effect on living organisms, in relatively higher concentration.

“… 159 The mechanisms of the action of bacterial phytohormones in plant growth regulation and their development have been reviewed by Kudoyarova et al 160 Some studies have indicated that the application of biochar partly boosts plant growth and development by activating the gibberellin pathway 161 and enhancing the transcription of auxin- and brassinosteroid-related genes, which play a key role in inducing systemic stress tolerance in plants. 162 …”

The contamination of soil with organic pollutants has been accelerated by agricultural and industrial development and poses a major threat to global ecosystems and human health. Various chemical and physical techniques have been developed to remediate soils contaminated with organic pollutants, but challenges related to cost, efficacy, and toxic byproducts often limit their sustainability. Fortunately, phytoremediation, achieved through the use of plants and associated microbiomes, has shown great promise for tackling environmental pollution; this technology has been tested both in the laboratory and in the field. Plant–microbe interactions further promote the efficacy of phytoremediation, with plant growth-promoting bacteria (PGPB) often used to assist the remediation of organic pollutants. However, the efficiency of microbe-assisted phytoremediation can be impeded by (i) high concentrations of secondary toxins, (ii) the absence of a suitable sink for these toxins, (iii) nutrient limitations, (iv) the lack of continued release of microbial inocula, and (v) the lack of shelter or porous habitats for planktonic organisms. In this regard, biochar affords unparalleled positive attributes that make it a suitable bacterial carrier and soil health enhancer. We propose that several barriers can be overcome by integrating plants, PGPB, and biochar for the remediation of organic pollutants in soil. Here, we explore the mechanisms by which biochar and PGPB can assist plants in the remediation of organic pollutants in soils, and thereby improve soil health. We analyze the cost-effectiveness, feasibility, life cycle, and practicality of this integration for sustainable restoration and management of soil.
