“…However, to combat the damaging effects of ROS on cells, plants generate antioxidative enzymes such as superoxide dismutase, peroxidase, catalase, glutathione reductase, and ascorbate peroxidase [ 126 , 128 ]. Interestingly, some plant miRNAs, such as miR398 and miR528, are known to regulate oxidative stress networks [ 127 , 129 , 130 ].…”

Plant stress is a significant challenge that affects the development, growth, and productivity of plants and causes an adverse environmental condition that disrupts normal physiological processes and hampers plant survival. Epigenetic regulation is a crucial mechanism for plants to respond and adapt to stress. Several studies have investigated the role of DNA methylation (DM), non-coding RNAs, and histone modifications in plant stress responses. However, there are various limitations or challenges in translating the research findings into practical applications. Hence, this review delves into the recent recovery, implications, and applications of epigenetic regulation in response to plant stress. To better understand plant epigenetic regulation under stress, we reviewed recent studies published in the last 5–10 years that made significant contributions, and we analyzed the novel techniques and technologies that have advanced the field, such as next-generation sequencing and genome-wide profiling of epigenetic modifications. We emphasized the breakthrough findings that have uncovered specific genes or pathways and the potential implications of understanding plant epigenetic regulation in response to stress for agriculture, crop improvement, and environmental sustainability. Finally, we concluded that plant epigenetic regulation in response to stress holds immense significance in agriculture, and understanding its mechanisms in stress tolerance can revolutionize crop breeding and genetic engineering strategies, leading to the evolution of stress-tolerant crops and ensuring sustainable food production in the face of climate change and other environmental challenges. Future research in this field will continue to unveil the intricacies of epigenetic regulation and its potential applications in crop improvement.

“…MicroRNAs (miRNAs), small RNA molecules with potent regulatory roles, emerge as key players in this regulatory ensemble. Under heavy metal stress, alterations in the expression of miRNAs become apparent, exerting influence on the abundance of target transcripts [ 161 , 196 ]. Notably, these transcripts are integral components of antioxidant pathways and secondary metabolism.…”

The paper provides a comprehensive examination of heavy metal stress on medicinal plants, focusing on its impact on antioxidant capacity and biosynthetic pathways critical to their therapeutic potential. It explores the complex relationship between heavy metals and the physiological and biochemical responses of medicinal plants, highlighting how metal stress disrupts biosynthetic pathways, altering concentrations of secondary metabolites. This disruption may compromise the overall quality and efficacy of medicinal plants, requiring a holistic understanding of its cumulative impacts. Furthermore, the study discusses the potential of targeted genetic editing to enhance plant resilience against heavy metal stress by manipulating genes associated with antioxidant defenses. This approach represents a promising frontier in safeguarding medicinal plants in metal-contaminated environments. Additionally, the research investigates the role of phytohormone signaling in plant adaptive mechanisms to heavy metal stress, revealing its influence on biochemical and physiological responses, thereby adding complexity to plant adaptation. The study underscores the importance of innovative technologies and global cooperation in protecting medicinal plants’ therapeutic potential and highlights the need for mitigation strategies to address heavy metal contamination effectively.

This chapter rigorously examines soil toxic metal/metalloid contamination and its profound implications on crop resilience, focusing on abiotic stress conditions. It begins by elucidating the natural and anthropogenic origins of soil contamination, illustrating how plants absorb these toxicants, and elaborating on their physio-molecular responses. The chapter accentuates the detrimental manifestations of impaired photosynthesis, nutrient uptake, and oxidative stress management, underscoring the urgent need for effective mitigation strategies. Phytoremediation and genetic engineering advancements are explored as promising strategies to optimize plant resilience in contaminated environments. Novel methodologies, including phytochelatins and the strategic application of genetic engineering, demonstrate potential in improving plant growth and resilience, showcasing significant advancements toward sustainable agricultural practices. Moreover, the interaction between plants and soil microbes is dissected, revealing a symbiotic relationship that influences the bioavailability of toxic metals/metalloids and optimizes plant health under stress conditions. This insight into microbial assistance opens new avenues for research and application in crop management and soil remediation. This chapter contributes essential knowledge toward bolstering crop resilience against toxic metal/metalloid contamination by presenting cutting-edge research findings and sophisticated mitigation techniques. It emphasizes the critical role of innovative research in overcoming the challenges posed by soil contamination, paving the way for achieving sustainable agricultural productivity and food security in the face of environmental stressors.
