Miscanthus x giganteus is often considered as a suitable plant species for phytomanagement of heavy metal polluted sites. Nevertheless, its physiological behavior in response to the level of metal toxicity throughout the growing season remains poorly documented. Miscanthus x giganteus was cultivated on three sites in Belgium (BSJ: non-polluted cont...

Arsenic (As) is a toxic metalloid, elevated levels of which in soils are becoming a major global environmental issue that poses potential health risks to humans. Pteris vittata, the first known As hyperaccumulator, has been successfully used to remediate As-polluted soils. Understanding why and how P. vittata hyperaccumulates As is the core theoret...

The ability of plants to accumulate heavy metals is a crucial factor in phytoremediation. This study investigated the effect of NaCl and S,S-ethylenediaminesuccinic acid (EDDS) on heavy metal accumulation in Kosteletzkya pentacarpos in soil polluted with arsenic, cadmium, lead, and zinc. The addition of NaCl reduced the bioavailability of arsenic a...

Climate change has intensified tomato plant infection by pathogens such as Pseudomonas syringae pv. tomato (Pst). Rootstocks may increase plant tolerance to leaf phytopathogens. The aim of this study was to evaluate the effects of the tolerant Poncho Negro (R) tomato rootstock on the physiological defence and the role of H2S in susceptible Limachin...

The widespread occurrence of cyanobacteria blooms damages the water ecosystem and threatens the safety of potable water and human health. Exogenous L-lysine significantly inhibits the growth of a dominant cyanobacteria Microcystis aeruginosa in freshwater. However, the molecular mechanism of how lysine inhibits the growth of M. aeruginosa is unclea...

With the rapid development of the mining industry, the pollution of heavy metal(loid)s in soils near copper (Cu) mining sites is a significant concern worldwide. However, the pollution status and probabilistic health risks of heavy metal(loid)s of soils associated with Cu mines, have rarely been studied on a global scale. In this study, eight heavy...

The aryl hydrocarbon receptor (AHR) is a member of the basic helix-loop-helix/Per-ARNT-Sim (bHLH-PAS) family of transcription factors and has broad biological functions. Early after the identification of the AHR, most studies focused on its roles in regulating the expression of drug-metabolizing enzymes and mediating the toxicity of dioxins and dio...

Kosteletzkya pentacarpos (L.) Ledebour is a perennial facultative halophyte species from the Malvacea family that grows in coastal areas with high amounts of salt. The tolerance of K. pentacarpos to the high concentration of salt (0.5–1.5% salinity range of coastal saline land) has been widely studied for decades. Nowadays, with the dramatic develo...

Abstract A comprehensive understanding of the relationship between arbuscular mycorrhizal (AM) fungi and coastal saline soil organic carbon (SOC) is crucial for analysis of the function of coastal wetlands in soil carbon sequestration. In a field experiment, the temporal and spatial dynamics of AM fungi, glomalin-related soil protein (GRSP) – which...

The halophyte plant species Kosteletzkya pentacarpos produces high amounts of mucilage which may play a role in heavy metal tolerance. The amount and composition of mucilage in K. pentacarpos exposed to zinc toxicity in the presence or in the absence of 50 mM NaCl was investigated. Exposure to 0.1 mM Zn had a detrimental impact on plants growth and...

Background and aims: Proline and glycinebetaine are osmolytes playing a role in resistance to salt and water stress but their involvement in plant adaptation to heavy metals remain unclear. Methods: Young plants of the halophyte Kosteletzkya pentacarpos were grown in nutrient solution in the presence of Cd (20 or 40 μM) or Zn (200 or 400 μM), or...

Phy­toman­age­ment of poly­con­t­a­m­i­nated soils is chal­leng­ing, es­pe­cially in ar­eas si­mul­ta­ne­ously af­fected by salin­ity. The wet­land halo­phyte plant species Kostelet­zkya pen­tacar­pos was cul­ti­vated in a col­umn de­vice al­low­ing leachate har­vest, on a poly­con­t­a­m­i­nated spiked soil con­tain­ing Cd (6.5 mg kg−1 DW), As (75...

Heavy metals such as cadmium and zinc constitute major pollutants in coastal areas and frequently accumulate in salt marshes. The wetland halophyte plant species Kosteletzkya pentacarpos is a promising tool for phytomanagement of contaminated areas. In order to assess the role of the antisenescing phytohormone cytokinin in heavy metal resistance in...

The halophyte species, Kosteletzkya pentacarpos, is known to produce high amount of mucilage, which may be thought to play a role in heavy metal tolerance. The quantity and composition of mucilage in K. pentacarpos exposed to zinc toxicity was therefore investigated. Exposure to 0.1 mM Zn had a detrimental impact on plants growth, leading to a sign...

Data regarding NaCl impact on halophyte plant species exposed to a polymetallic contamination remain scarce. Seedlings of the salt marsh species Kosteletzkya pentacarpos were simultaneously exposed to cadmium (10 μM) and zinc (100 μM) in the absence or presence of 50 mM NaCl. Heavy metal exposure reduced plant growth and increased Cd and Zn concent...

A pot culture experiment was performed to study the effects of infection with different proportions of arbuscular mycorrhizal fungus (AMF) and phosphate-solubilizing fungus (PSF) on the rhizosphere soil property of castor bean (Ricinus communis L.). One AMF, Glomus mosseae, and one PSF, Mortierella sp. (Ms), were applied to non-sterilized coastal s...

Selecting Qingkou saltfarm of Lianyungang, Jinhai farm of Yancheng, and Xiaoyangkou beach field of Nantong as study sites, the species amount, plant height, relative abundance and frequentness of Kosteletzkya virginica plantations were investigated, and the vegetation diversity was evaluated and researched. The results showed that: (1) The amounts...
