    Jasmonic Acid-Mediated Defense in Vicia faba: Alleviating Fungicide-Induced Oxidative Stress
    (Book Rivers, 2026) Aneeta Tiwari, Ashish Verma
    Plants are constantly subjected to various environmental stressors that significantly impede their growth and limit agricultural productivity. These stressors are classified as abiotic (such as extreme temperatures, drought, salinity, radiation, and heavy metals) and biotic (including fungi, bacteria, viruses, nematodes, and herbivores). To counter these challenges, plants have developed sophisticated defense mechanisms that involve sensing stress signals, activating signaling cascades, and initiating cellular responses. In agricultural settings, plants frequently face combined stress conditions, intensifying damage and reducing yields. Among the most damaging biotic agents are fungi and oomycetes, which are responsible for substantial global crop losses. The faba bean (Vicia faba L.), a widely cultivated legume, is highly susceptible to various fungal diseases such as rust, chocolate spot, ascochyta blight, leaf spots, and root rot complexes, often resulting in severe defoliation and yield decline. Disease management traditionally involves resistant crop varieties, improved cultural practices, and the extensive use of fungicides like mancozeb. While fungicides such as mancozeb effectively suppress pathogens, their overuse leads to oxidative stress due to the accumulation of reactive oxygen species (ROS), which disrupt cellular homeostasis. Plants mitigate oxidative damage through robust antioxidant systems comprising enzymatic (SOD, CAT, POD) and non-enzymatic (ascorbate, glutathione, carotenoids) components. Plant growth regulators (PGRs), particularly jasmonic acid (JA), have emerged as critical tools in enhancing plant resilience by strengthening antioxidant defenses and regulating stress responses. JA modulates stress adaptation by interacting with other phytohormones and regulating key physiological processes, thereby offering a promising, eco-friendly strategy to reduce the adverse impacts of both environmental stress and chemical treatments.

    Hydrogen Peroxide Signalling Mechanisms and Crosstalk in Plant Development and Stress Responses
    (CRC Press, 2025) Mohd Tanveer Alam Khan, Taiba Saeed, Aqeel Ahmad, Qazi Fariduddin , Mohammad Yusuf
    Hydrogen peroxide (H2O2) is recognized as a crucial signalling molecule that mediates physiological and biochemical processes in plants, regulating various development and stress responses. Hydrogen Peroxide: Signalling Mechanisms and Crosstalk in Plant Development and Stress Responses presents a comprehensive overview of hydrogen peroxide’s modes of action in plants, demonstrating the important role played in plant stress signaling and communication. It produces key topics in H2O2 research such as plant signaling, molecular responses, and interaction with other hormones. Features · Discusses experiments interrelated to H2O2 signalling pathway in plants under various environmental conditions. · Addresses important concerns in H2O2 research from a wide range of organisms, including plants and prokaryotes such as bacteria and archaea. · Collects, summarizes, and presents developments in plant signaling and communication. · Aids scientists and breeders in developing strategies to enhance plant growth and stress tolerance. Environmental stress is destructively disturbing plant growth and efficiency, resulting in concerns to improve food crop yield, and H2O2 has immense field implications as it is vital in regulating plant growth and stress responses. Hydrogen Peroxide: Signalling Mechanisms and Crosstalk in Plant Development and Stress Responses is an invaluable resource for researchers and scientists to use as a guide to conduct studies on environmental conditions of the plant hydrogen peroxide signaling systems.
