“…Under abiotic stress conditions, Si enhanced the metabolism and synthesis of phytohormones in plants ( Zhu and Gong, 2014 ; Kim et al, 2016 ). The major phytohormones upregulated by Si under abiotic stress conditions include ABA, JA, GA, ET, SA, BR, and IAA ( Arif et al, 2021 ). Si-induced phytohormones synergistically regulate the growth, metabolism, and stress tolerance in pepper, as shown by in silico data analysis ( Gómez-Merino et al, 2020 ).…”

“…GAs are an important class of phytohormones critical to plants, such as seed germination and fruiting ( Colebrook et al, 2014 ). The endogenous levels of GA are upregulated under salinity stress in Glycine max upon application of Si at 2.5-mM concentration ( Arif et al, 2021 ; Dhiman et al, 2021 ). The Si-triggered upregulation of GA 1 and GA 4 content in cucumber plants helps to withstand drought and salinity stress ( Hamayun et al, 2010 ).…”

“…The growth and the metabolism of plants are improved through their mechanisms to develop tolerance against abiotic stressors. Later attributes were primarily alleviated by supplementation of Si to withstand negative environmental stress factors ( Arif et al, 2021 ; Souri et al, 2021 ). In sugarcane, Si has been attributed to enhancing leaves’ rigidity and erectness, resulting in improved photosynthesis ( Verma et al, 2019 ).…”

“…These genes are reportedly involved in solute transport, hormone biosynthesis and signaling, and biotic and abiotic stress response. A good percentage of differentially expressed genes in response to Si treatment are transcription factors ( Zhu et al, 2019b ; Arif et al, 2021 ). Liu P. et al (2015) and Manivannan and Ahn (2017) reported that Si-upregulated SbPIP gene coding plasma membrane intrinsic protein (PIP) is vital for maintaining uptake of water by positively regulating the aquaporin activity and additionally enhanced salt tolerance in sorghum.…”

“…Abiotic stressors alter the homeostasis of the physiological, molecular, and biochemical setup of crop plants, such as water relations, nutrient uptake and assimilation, osmotic deregulation, loss of membrane integrity, impairment in enzyme activity, and the most notable decline in photosynthetic efficiency ( Moradtalab et al, 2018 ; Ahanger et al, 2019 ; Raza, 2021 ; Raza et al, 2021e ). Most of these impairments after exposure to the stress factors are associated with phytohormone production and their transport in underground and aerial parts of plants ( Gangwar et al, 2014 ; Verma et al, 2016 ; Arif et al, 2021 ). Moreover, plants primarily respond to these abiotic stressors by producing reactive oxygen species (ROS), which, in turn, induce severe damage to the cellular structures, such as biomembranes and organelles ( da Silva and Yücel, 2008 ; Hasanuzzaman et al, 2020 ).…”

Sustainable agricultural production is critically antagonistic by fluctuating unfavorable environmental conditions. The introduction of mineral elements emerged as the most exciting and magical aspect, apart from the novel intervention of traditional and applied strategies to defend the abiotic stress conditions. The silicon (Si) has ameliorating impacts by regulating diverse functionalities on enhancing the growth and development of crop plants. Si is categorized as a non-essential element since crop plants accumulate less during normal environmental conditions. Studies on the application of Si in plants highlight the beneficial role of Si during extreme stressful conditions through modulation of several metabolites during abiotic stress conditions. Phytohormones are primary plant metabolites positively regulated by Si during abiotic stress conditions. Phytohormones play a pivotal role in crop plants’ broad-spectrum biochemical and physiological aspects during normal and extreme environmental conditions. Frontline phytohormones include auxin, cytokinin, ethylene, gibberellin, salicylic acid, abscisic acid, brassinosteroids, and jasmonic acid. These phytohormones are internally correlated with Si in regulating abiotic stress tolerance mechanisms. This review explores insights into the role of Si in enhancing the phytohormone metabolism and its role in maintaining the physiological and biochemical well-being of crop plants during diverse abiotic stresses. Moreover, in-depth information about Si’s pivotal role in inducing abiotic stress tolerance in crop plants through metabolic and molecular modulations is elaborated. Furthermore, the potential of various high throughput technologies has also been discussed in improving Si-induced multiple stress tolerance. In addition, a special emphasis is engrossed in the role of Si in achieving sustainable agricultural growth and global food security.

Rapid synchronized seed germination is desirable to ensure seedling establishment and improve crop yield.However, abiotic stresses from drought, salinity, and heavy metals have a negative impact on seed germination.The application of silicon (Si) has emerged as a promising approach for improving seed germination, especially under unfavorable conditions. However, the mechanisms of Si action have not been systematically studied in germinating seeds under conditions of abiotic stress. Considering the potential importance of sustainable agriculture, here we review recent findings of how seeds of numerous species, including several important crops, respond to Si treatment under abiotic stress. Exogenous Si has multiple effects on embryo viability, reserve mobilization, hormone/enzyme activity, membrane integrity, antioxidant metabolism, and regulation of gene expression in seed germination.
