Background and aims Chelates like ethylenediaminetetraacetic acid (EDTA) have frequently been applied for facilitating lead (Pb) phytoextraction and cleaning contaminated soils but without detailed report regarding the internal mechanisms happening in plants in response to EDTA addition.

Aims and Background

In recent decades, recycling of wastewater has received increasing attention among researchers, because it can satisfy the proliferating demand for groundwater and reduce water shortages in developed and developing countries.

Methods

Purpose Aquatic plants, including rice, develop iron (Fe) plaques on their roots due to radial oxygen loss (ROL), and these plaques accumulate both beneficial and toxic elements. Silicon is an important nutrient for rice and both accumulates in Fe plaque and can affect ROL.

Purpose Over-accumulation of cadmium and lead in rice grain is a global concern as it has adverse health impacts.

Purpose Although mitigation approaches have been developed to reduce Cd in cacao beans, the efficacy of the approaches have been inadequate to make them economically viable.

Phytoextraction is an eco-friendly approach for remediation of heavy metal contaminated soil.

Rice is a staple crop worldwide and a silicon (Si) hyperaccumulator with Si levels reaching 5–10% of its mass; this can result in desilication and Si-deficiency if plant residues are not managed correctly. Rice is also uniquely subject to arsenic (As) and cadmium (Cd) contamination depending on soil conditions.

Iron (Fe) deficiency in plants is a common problem affecting agricultural production. Cadmium (Cd) is a toxic metal that can be taken up and transported within plants by transporters for divalent metals including Fe(II).

Imazethapyr (IM) is a chiral herbicide with two enantiomers, with a much stronger herbicidal effect of R-IM than S-IM. Pesticide residues are a common problem, and multi-generation cultivation method can reveal the consequences of long-term pesticide residues. Methods This study verified the effects of R-IM on the growth of Arabidopsis thaliana and rhizosphere microorganisms by treating A.

High mountain environments are among the most fragile on Earth. Due to anthropogenic disturbances and the exposure to extreme weather events, the rates of soil erosion have recently been accelerating, resulting in ecological degradation and geological hazards. Ecological restoration of mountains and an improved understanding of nature-based solutions to mitigate land degradation is therefore of utmost urgency.

Purpose It is unknown how the Cd-mediated changes in the rhizospheric nitrifier community affect plant growth under different water management practices.

Abstract Purpose Increasing evidence indicates that trees could emit methane (CH4) from soils into the atmosphere.

Abstract

Purpose

Diverse rare taxa are increasingly recognized as drivers of key functions in ecosystems. However, less attention has been given to their importance in the remediation of metal-contaminated soils by phytoextraction.

Abstract

Purpose

Aerenchymous plants are an important control for methane efflux from peatlands to the atmosphere, providing a bypass from the anoxic peat and avoiding oxidation in the oxic peat. We aimed to quantify the drivers of aerenchymous peatland species methane transport and the importance of this process for ecosystem-scale methane efflux.

Abstract

Abstract

Aims

To investigate phylogenetic and phenotypic diversity of resident chickpea-nodulating rhizobia from Australian cropping soils.

Abstract

Aims

The rhizosphere microbiome plays an important role in plant growth and behavior during phytoremediation. This work aims to explore how hyperaccumulating plant performance (shoot biomass and Cd uptake) and rhizosphere bacterial community are driven by plant development under a Cd concentration gradient and their relationship during plant growth.

Non-essential and toxic for all living organisms, cadmium (Cd) is a trace element to which a significant part of the world population is chronically overexposed through the consumption of food made from cereals, tubers or vegetables (Clemens et al. 2013). Cadmium in these plant products comes from the soil, through root absorption and translocation to the harvested organs (Sterckeman and Thomine 2020).

Abstract

Aims

Grafting is an effective strategy to reduce the accumulation of cadmium (Cd) from the soil to the aerial plant parts. However, few studies have investigated the mechanisms involved.

Abstract

Aims

Sugars in soils play vital roles in soil aggregation and microbial activity, which is easily affected by environmental factors. Here, we investigated the accumulation of total sugars and monosaccharides in the rhizosphere soil of black locust seedlings exposed to the contamination of elevated atmospheric CO2 (eCO2) and cadmium (Cd) and its driving factors.

Abstract

Abstract

Purpose

Evaluation of various mechanisms of Cd2+ and Zn2+ root uptake through modelling, including interactions with Fe uptake.

Abstract

Abstract

Aims

Phosphorus (P) fertilizers are often considered an important source of cadmium (Cd) in crop plants. However, increased plant Cd concentrations are not strictly related to the Cd content of P fertilizers. Considering this, we hypothesized that, alternatively, reduction of arbuscular mycorrhizal colonization by P fertilization enhances Cd accumulation in plants.
