Apple Academic Press.9781003622321978-104035366-0https://hdl.handle.net/20.500.12604/8690Silicon (Si) is considered as the second most prevalent element in the Earth’s crust, having functional involvements in ionic homeostasis, water status, photosynthetic pathways, and other physiological processes. Silicon-mediated beneficial effects on plants have been elucidated against biotic and abiotic stresses. Silicon fertilization has been shown to be a significant remedial measure to enhance the growth and yield of many crop plants under stressful environments. Silicon-mediated stress alleviation comprises vital regulatory mechanisms, including prevention from oxidative damage caused by reactive oxygen species (ROS), osmotic balance, nutrient management, and tolerance to pests and diseases in many plant species. The mechanisms related to mitigating stresses by Si supplementation are associated with the activation of enzymatic and non-enzymatic antioxidants. Such stress-mitigating processes significantly vary with crop species, soil characteristics, and plant and environmental interactions. In addition, the molecular mechanisms of Si involvement and the expression of related genes associated with Si-mediated stress mitigation need to be explored for better understanding. Thus, our attempt in this chapter is to explain the role of Si and nano-silicon (SiNP) in ameliorating biotic and abiotic stresses and their underlying mechanisms.eninfo:eu-repo/semantics/closedAccesscatalaseglutathione reductaseheavy metalnanofertilizersplasma membrane intrinsic proteinsuperoxide dismutasebook-chapterN/A2-s2.0-10500570269910.1201/9781003622321-4
