“…Similarly, in semi-controlled conditions, foliar application of λ-carrageenan triggered both SA- and JA-dependent signaling pathways in wheat, protecting the plant from Z. tritici (Le Mire et al 2019 ). Likewise, plant biostimulant oligochitosan can protect plants against fungi, bacteria, and viruses by activating the SA and JA–ET pathways (Moenne and González 2021 ). Application of fungal elicitor chitosan induced key genes in both SA (Xing et al 2009 ) and JA (Farmer and Ryan 1992 ).…”

In the context of climate change, the need to ensure food security and safety has taken center stage. Chemical fertilizers and pesticides are traditionally used to achieve higher plant productivity and improved plant protection from biotic stresses. However, the widespread use of fertilizers and pesticides has led to significant risks to human health and the environment, which are further compounded by the emissions of greenhouse gases during fertilizer and pesticide production and application, contributing to global warming and climate change. The naturally occurring sulfated linear polysaccharides obtained from edible red seaweeds (Rhodophyta), carrageenans, could offer climate-friendly substitutes for these inputs due to their bi-functional activities. Carrageenans and their derivatives, known as oligo-carrageenans, facilitate plant growth through a multitude of metabolic courses, including chlorophyll metabolism, carbon fixation, photosynthesis, protein synthesis, secondary metabolite generation, and detoxification of reactive oxygen species. In parallel, these compounds suppress pathogens by their direct antimicrobial activities and/or improve plant resilience against pathogens by modulating biochemical changes via salicylate (SA) and/or jasmonate (JA) and ethylene (ET) signaling pathways, resulting in increased production of secondary metabolites, defense-related proteins, and antioxidants. The present review summarizes the usage of carrageenans for increasing plant development and defense responses to pathogenic challenges under climate change. In addition, the current state of knowledge regarding molecular mechanisms and metabolic alterations in plants during carrageenan-stimulated plant growth and plant disease defense responses has been discussed. This evaluation will highlight the potential use of these new biostimulants in increasing agricultural productivity under climate change.

“…The adsorption mechanism of CS-based adsorbents for Cd removal primarily relies on physical adsorption, complexation, electrostatic attraction, chelation, and ion exchange (Mola Ali Abasiyan et al, 2019). Several studies have reported the successful application of CS-based adsorbents for Cd removal from contaminated soil (Omer et al, 2022).…”

“…These precipitates can then be separated from the solution, effectively removing the HM ions (Lee et al, 2020). In acidic and neutral pH conditions, CS and CS-based composites carry a positive charge due to the protonation of amino groups (Mola Ali Abasiyan et al, 2019). It is essential to consider that the specific mechanisms governing Cd and As adsorption may vary depending on factors such as pH, metal concentration, CS properties, and the presence of other ions in the solution (X.…”

Cadmium (Cd) and arsenic (As) are both potentially toxic heavy metals (HMs) found ubiquitously in the environment. These HMs are prevalent in soil due to natural occurrences or anthropogenic activities. Co-contamination of Cd and As in soil is a major concern for plant and human health as well as ecosystem sustainability due to their hazardous properties. Therefore, a global imperative is developing improved technologies for managing and remediating soil co-contaminated with Cd and As. One effective solution for remediating Cd/As co-contaminated soil involves the utilization of natural biopolymers and biostimulants, such as chitosan (CS). CS offers distinct advantages, including its ready availability, biodegradability, biocompatibility, environmental friendliness, and cost-effectiveness when compared to alternative adsorbents. The adsorption mechanism of CS and CS-based adsorbents for Cd and As primarily relies on electrostatic attraction, complexation, and ion exchange. This review article provides a comprehensive overview of Cd and As co-contamination in soil, elucidating their sources, distribution patterns, exposure pathways, and the prospective remediation approaches employing CS biostimulants and CS-based adsorbents. Furthermore, it summarizes recent studies investigating the adsorption of Cd/As by CS, the factors influencing the adsorption efficiency and the challenges associated with the utilization of CS and CS-based adsorbents. In conclusion, the review underscores the need for further research to concurrently remediate Cd and As co-contaminated soil, enhance the adsorption efficiency of CS and CS-based composites, and broaden their practical applicability for remediating co-contaminated soils.

“…e value of b (1,567 mg/g) in the Langmuir isotherm describes the maximum capacity of fluoride in the soil after the amendment. e study by Abasiyan et al (2019), reported that the amount of b was higher in the soil compared to the same adsorbent in the water system [28]. e high adsorption in the soil is accounted for the presence of other adsorbents containing a variety of functional groups such as carboxyl, phenolic, and carbonyl which interact and bind with the target ions in the soil.…”

This study investigated the efficacy of fermented seaweed (Eucheuma cottonii) on the remediation of fluoride-contaminated soil. The soil was amended with either 1.25, 3.0, or 5.0% (w/w) fermented seaweed (FSW), parallel with the controls (0%). The amendment improved the physicochemical properties of the soil particularly pH regulated from strong alkaline (9.3) to neutral (7.0) which is essential for germination, crop growth, and yield. The amount of water soluble-fluoride (Ws-F) dropped from 81.7 ± 3.1 mg/kg to 42.7 ± 2.4, 33.7 ± 1.2, 19.6 ± 0.9, and 12 ± 1.3 mg/kg following 0, 1.25, 3, and 5% amendment dosage, respectively. Most of the Ws-F was converted into exchangeable fluoride (Ex-F) and to fluoride-bound to iron and manganese (Fe/Mn-F). Furthermore, the amendment also enhanced microbial mass and diversity in the soil. The FSW contains organic acids which participate in ionic bonding with the multivalent cations in the soil. The formed compound participates in ion exchange with clay or with anionic adsorption to positively charged clay sites at the edges. This interaction is further essential for enhancing the fluoride holding capacity of the soil. The use of seaweed reduced the bioavailability of fluoride in the agricultural soils and had positive effects on promoting soil fertility. However, further studies to observe its effects on crop performance is of significance.
