“…Cell damage caused by oxidative stress is considered to be a major adverse effect of heavy metal exposure [70]. Arsenic exposure led to H 2 O 2 accumulation and cell damage by increased lipid peroxidation [25,71,72]. In this study, we hypothesized that the plants effectively coping with oxidative stress would thrive better under As treatment.…”

“…In the context of arsenic stress, it is important to note that it induces the production of reactive oxygen species (ROS) [16,[24][25][26]. To protect themselves, plants have developed sophisticated defensive mechanisms, including the action of antioxidant enzymes (superoxide dismutase, catalase, peroxidases like ascorbate peroxidase and glutathione-S-transferase) and antioxidant molecules (e.g., phenolic compounds, ascorbate, glutathione, and proline) [27].…”

Multi-Component Antioxidative System and Robust Carbohydrate Status, the Essence of Plant Arsenic Tolerance

Arsenic (As) contaminates the food chain and decreases agricultural production through impairing plants, particularly due to oxidative stress. To better understand the As tolerance mechanisms, two contrasting tobacco genotypes: As-sensitive Nicotiana sylvestris and As-tolerant N.tabacum, cv. ‘Wisconsin’ were analyzed. The most meaningful differences were found in the carbohydrate status, neglected so far in the As context. In the tolerant genotype, contrary to the sensitive one, net photosynthesis rates and saccharide levels were unaffected by As exposure. Importantly, the total antioxidant capacity was far stronger in the As-tolerant genotype, based on higher antioxidants levels (e.g., phenolics, ascorbate, glutathione) and activities and/or appropriate localizations of antioxidative enzymes, manifested as reverse root/shoot activities in the selected genotypes. Accordingly, malondialdehyde levels, a lipid peroxidation marker, increased only in sensitive tobacco, indicating efficient membrane protection in As-tolerant species. We bring new evidence of the orchestrated action of a broad spectrum of both antioxidant enzymes and molecules essential for As stress coping. For the first time, we propose robust carbohydrate metabolism based on undisturbed photosynthesis to be crucial not only for subsidizing C and energy for defense but also for participating in direct reactive oxygen species (ROS) quenching. The collected data and suggestions can serve as a basis for the selection of plant As phytoremediators or for targeted breeding of tolerant crops.

“…Additionally, plants can absorb these metal chelates; for example, siderophores from Pseudomonas aeruginosa and Pseudomonas fluorescens enhance maize's uptake of chromium and lead [73]. Siderophores can also mitigate heavy metal toxicity in plants, as shown by hydroxamate-type siderophores from Aspergillus species reducing arsenic poisoning in wheat [74], and dihydroxamate-type siderophores from cyanobacteria decreasing cadmium poisoning risk in rice [75].…”

Siderophores are a class of small molecules renowned for their high iron binding capacity, essential for all life forms requiring iron. This article provides a detailed review of the diverse classifications, and biosynthetic pathways of siderophores, with a particular emphasis on siderophores synthesized via nonribosomal peptide synthetase (NRPS) and non-NRPS pathways. We further explore the secretion mechanisms of siderophores in microbes and plants, and their role in regulating bioavailable iron levels. Beyond biological functions, the applications of siderophores in medicine, agriculture, and environmental sciences are extensively discussed. These applications include biological pest control, disease treatment, ecological pollution remediation, and heavy metal ion removal. Through a comprehensive analysis of the chemical properties and biological activities of siderophores, this paper demonstrates their wide prospects in scientific research and practical applications, while also highlighting current research gaps and potential future directions.

“…Here, the optimum siderophore concentration was 50 SU/ml, where higher concentrations negatively affected the B. subtilis growth due to the chelation of essential nutrients. A study by ( Kumari et al., 2019 ) examined the use of the hydroxamate-type siderophore (ferricrocin) isolated from A. nidulans to reduce the adverse impact of arsenic under toxic conditions on Triticum aestivum growth. The formation of the thermodynamically stable ferricrocin–arsenate complex recovered plant growth and assisted in adjusting superoxide dismutase, catalase, and peroxidase activity of wheat while reducing damage caused by lipid peroxidation ( Kumari et al., 2019 ).…”

The hidden power of secondary metabolites in plant-fungi interactions and sustainable phytoremediation

The global environment is dominated by various small exotic substances, known as secondary metabolites, produced by plants and microorganisms. Plants and fungi are particularly plentiful sources of these molecules, whose physiological functions, in many cases, remain a mystery. Fungal secondary metabolites (SM) are a diverse group of substances that exhibit a wide range of chemical properties and generally fall into one of four main family groups: Terpenoids, polyketides, non-ribosomal peptides, or a combination of the latter two. They are incredibly varied in their functions and are often related to the increased fitness of the respective fungus in its environment, often competing with other microbes or interacting with plant species. Several of these metabolites have essential roles in the biological control of plant diseases by various beneficial microorganisms used for crop protection and biofertilization worldwide. Besides direct toxic effects against phytopathogens, natural metabolites can promote root and shoot development and/or disease resistance by activating host systemic defenses. The ability of these microorganisms to synthesize and store biologically active metabolites that are a potent source of novel natural compounds beneficial for agriculture is becoming a top priority for SM fungi research. In this review, we will discuss fungal-plant secondary metabolites with antifungal properties and the role of signaling molecules in induced and acquired systemic resistance activities. Additionally, fungal secondary metabolites mimic plant promotion molecules such as auxins, gibberellins, and abscisic acid, which modulate plant growth under biotic stress. Moreover, we will present a new trend regarding phytoremediation applications using fungal secondary metabolites to achieve sustainable food production and microbial diversity in an eco-friendly environment.
