“…Upregulation of GAs can ameliorate the abiotic stress conditions to maintain the growth and development of plants. In addition, upon exogenous application of SA, plants exhibit tolerance to various abiotic stresses like drought, heat, chilling, and tolerance to other stressors like viral, fungal, and bacterial attacks ( Prakash et al, 2021 ; Saleem et al, 2021 ). Phytohormones like ABA are upregulated during osmotic stress to enhance tolerance by expressing several genes ( Al Murad 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.

“…However, there has been no direct correlation between SA treatment and chilling tolerance. In fact, other than a slight endogenous increase in SA acid levels, rice plants did not respond positively to the treatment; exogenous SA seemed to result in reduction of chilling tolerance in rice [ 76 ]. While studies have shown that low temperature increases SA/oHCA levels in all plants including cereals, it would seem that SA was not an efficient secondary signal in eliciting a defense response to chilling in rice.…”

Environmental or abiotic stresses are a common threat that remains a constant and common challenge to all plants. These threats whether singular or in combination can have devastating effects on plants. As a semiaquatic plant, rice succumbs to the same threats. Here we systematically look into the involvement of salicylic acid (SA) in the regulation of abiotic stress in rice. Studies have shown that the level of endogenous salicylic acid (SA) is high in rice compared to any other plant species. The reason behind this elevated level and the contribution of this molecule towards abiotic stress management and other underlying mechanisms remains poorly understood in rice. In this review we will address various abiotic stresses that affect the biochemistry and physiology of rice and the role played by SA in its regulation. Further, this review will elucidate the potential mechanisms that control SA-mediated stress tolerance in rice, leading to future prospects and direction for investigation.

“…Optimal allocation of P in plants can prolong and improve the P utilization in PS (Veneklaas et al, 2012). It has been reported that foliar application of plant growth regulators (i.e., SLs, salicylic acid, and ABA) significantly enhanced the activities of antioxidant enzymes, which facilitates in preventing membrane peroxidation under drought and LTS (Sun et al, 2009;Ma et al, 2017;Saleem et al, 2021). Accumulation of fructans in cereal crops upon experiencing low temperature environmental conditions is another preventive approach in maintaining membrane stability (Livingston et al, 2009).…”

The 21st century presents many challenges to mankind, including climate change, fast growing human population, and serious concerns over food security. Wheat is a leading cereal crop that largely fulfills the global food needs. Low temperature stress accompanied by nutrient-starved soils is badly disrupting the source–sink relationship of wheat, thus causing an acute decline in final yield and deteriorating the grain quality. This review paper aimed to understand how low temperature stress affects wheat source–sink organs (i.e., leaves, roots, and spikes) and how phosphorus application reliefs in alleviating its harmful consequences. Also, we discussed mitigation strategies to enhance wheat capacity to adapt to varying temperature extremes and made rational recommendations based on modern agronomic and breeding approaches. Therefore, this study is likely to establish a solid foundation for improving the tolerance to low temperature stress and to improve its phosphorus utilization efficiency in wheat.
