“…Cold stress damages lipids, proteins, carbohydrates, and nucleic acids through the production of ROS ( Suzuki et al, 2012 ). To avoid this, plants have adopted several strategies to combat the cold stress for maintaining growth and development ( Dey et al, 2022 ). Habibi (2015) reported that foliar-applied Si effectively alleviates the cold stress by maintaining the integrity of bio-membranes and decreasing photoinhibition in grapevine plants.…”

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.

“…Photosynthetic apparatuses represented by photosystem II, cytochrome b6/f complex, photosystem I and F-type ATPase are easily influenced by environmental changes (Dey et al, 2022). Numerous studies in the past decades have demonstrated that the extrinsic PsbO, PsbP, and PsbQ proteins play important roles in maintaining optimal manganese, calcium and chloride concentrations at the active site of photosystem II, and chemical or genetic removal of these components will induce multiple and profound defects in photosystem II function and oxygen-evolving complex stability (Bricker and Frankel, 2011;Ifuku and Nagao, 2021).…”

Codonopsis tangshen Oliv (C. tangshen) is an important Chinese traditional medicinal plant with various health benefits. However, the growth of C. tangshen are seriously affected by continuous cropping, which led to the decrease of the yield and quality. A field experiment was conducted to learn the effects of soil amendments on the growth of C. tangshen under continuous cropping condition, and the biological events which occurred at molecular level were investigated. The results indicated that the content of chlorophyll a (Chl a), chlorophyll b (Chl b), and carotenoid (Car) was significantly higher in SCPM (silicon-calcium-potassium-magnesium fertilizer), SCPMA (SCPM combined with azoxystrobin) and SCPMAOM (SCPM combined with azoxystrobin and organic manure) treatments. Moreover, the yield and the levels of alkaloid, polysaccharide, flavone and total protein in the treatments of SCPM, SCPMA and SCPMAOM were significantly higher than those in the control, and these indexes were all highest in the SCPMAOM treatment. RNA-sequencing (RNA-Seq) is an economical and efficient method to obtain genetic information for species with or without available genome data. In this study, RNA-Seq was performed to understand how continuously cropped C. tangshen responded to the soil amendments at the transcriptome level. The number of differentially expressed genes (DEGs) were as follows: CK vs. SCPM (719 up- and 1456 down-), CK vs. SCPMA (1302 up- and 1748 down-), CK vs. SCPMAOM (1274 up- and 1678 down-). The soil amendments affected the growth of C. tangshen mainly by regulating the genes involved in pathways of ‘photosynthesis,’ ‘plant hormone signal transduction,’ ‘biosynthesis of unsaturated fatty acids,’ ‘phenylpropanoid biosynthesis,’ and ‘starch and sucrose metabolism,’ etc. qRT-PCR was performed to validate the expressions of 10 target genes such as CP26, PsaF, and POX, etc., which verified the reliability of RNA-Seq results. Overall, this study revealed the roles and underlying mechanisms of the soil amendments in regulating the growth of continuously cropped C. tangshen at transcriptome level. These findings are beneficial for improving the continuous cropping tolerance and may be valuable for future genetic improvement of C. tangshen.

“…As these plants are sessile in nature and unable to move in a more favorable environments, the plant functional processes are substantially affected, often lethally, by elevated temperature (Raza, 2020 ; Ahmad M. et al, 2021 ). The primary mechanism of cellular membrane disruption under heat stress severely affects the photosynthetic and mitochondrial activities and decreases the ability of the plasma membrane to retain solutes (Chauhan et al, 2020 ; Dey et al, 2021 ). An elevated-temperature impairment can ensue in huge pre-harvest and post-harvest crop causalities.…”

The impact of elevated temperature at the reproductive stage of a crop is one of the critical limitations that influence crop growth and productivity globally. This study was aimed to reveal how sowing time and changing field temperature influence on the regulation of oxidative stress indicators, antioxidant enzymes activity, soluble sugars (SS), and amino acids (AA) in Indian Mustard. The current study was carried out during the rabi 2017–2018 and 2018–2019 where, five varieties of mustard viz. Pusa Mustard 25 (PM-25) (V1), PM-26 (V2), BPR-541-4 (V3), RH-406 (V4), and Urvashi (V5) were grown under the field conditions on October 30 (normal sowing; S1), November 18 (late sowing; S2) and November 30 (very late sowing; S3) situations. The S1 and S3 plants, at mid-flowering stage, showed a significant variation in accumulation of SS (8.5 and 17.3%), free AA (235.4 and 224.6%), and proline content (118.1 and 133%), respectively, and played a crucial role in the osmotic adjustment under stress. The results showed that S3 sowing, exhibited a significant induction of the hydrogen peroxide (H2O2) (110.2 and 86.6%) and malondialdehyde (23.5 and 47.5%) concentrations, respectively, which indicated the sign of oxidative stress in plants. Interestingly, the polyphenol oxidase, peroxidase, superoxide dismutase, and catalase enzyme activities were also significantly increased in S3 plants compared to S1 plants, indicating their significant roles in ameliorating the oxidative stress. Furthermore, the concentration of fatty acid levels such as palmitic, stearic, oleic, and linoleic acids level also significantly increased in S3 plants, which influenced the seed and oil quality. The study suggests that the late sowing significantly impaired the biochemical mechanisms in Indian mustard. Further, the mustard variety V4 (RH-406) was found to be effective for cultivation as well as environmental stress adoption in Indian soils, and it could be highly useful in breeding for developing heat-tolerant genotypes for ensuring the food security.
