“…The significant effect of B. thuringiensis, perhaps due to the production of growth substances such as auxin, cytokinin, and nutrient availability, as well as the upregulation of essential enzymes [65]. Interestingly enough, Si application can activate the plant defenses by boosting the activity of enzymes CAT, SOD, POX, and PPO, whic, scavenge ROS and protect the cells from oxidative damage [71].…”

“…Also, B. thuringiensis was reported to counteract the oxidative stress of ROS under saline conditions in sweet pepper and keep the cell membrane from being damaged [6]. Additionally, Si application led to mitigation of the harmful influence of salinity in lettuce plants and significantly decreased the levels of O 2 − and H 2 O 2 , because Si plays a vital role as an anti-stress compound [71,73]. In summary, salinity stress caused a reduction in number of leaves, head weight, total yield of lettuce plants, and increase in EL%, MDA, and reactive oxygen species.…”

We investigated the impact of Bacillus thuringiensis as seed treatment and application with silicon on lettuce plants exposed to salinity levels (4 dS m−1 and 8 dS m−1). Results revealed that leaves number, head weight, total yield, relative water content (RWC), and chlorophyll a and b declined considerably due to two salinity levels. Oxidative stress markers, i.e., hydrogen peroxide (H2O2), superoxide (O2−), and lipid peroxidation (MDA) dramatically augmented in stressed plants. On the other hand, leaves number, total yield, RWC, and chlorophyll a, b in stressed lettuce plants were considerably enhanced because of the application of Si or B. thuringiensis. In contrast, EL%, MDA, and H2O2 were considerably reduced in treated lettuce plants with Si and B. thuringiensis. In addition, the treatment with Si and B. thuringiensis increased head weight (g) and total yield (ton hectare-1), and caused up-regulation of proline and catalase, superoxide dismutase, peroxidase, and polyphenol oxidase activity in lettuce leaves under salinity conditions.

“…Вона відіграє важливу функцію у розвитку структурної цілісності біологічних організмів [3]. Проте ортосилікатна кислота у водному розчині існує в дуже незначних кількостях [4], є досить нестабільною і легко переходить у недоступні полімерні форми [5]. Стабілізація ортосилікатна кислоти у водному розчині відбувається за рахунок зв'язування її з різноманітними органічними та неорганічними сполуками [6].…”

У роботі проводилось теоретичне дослідження на рівні DFT, де було показано енергетичні параметри водневих зв’язків для кластерів складу H4SiO4 · L, де L – H2O, CH3SO3H, CH3SO3−, H3PO4, H2PO4−, HPO42−, PO43−, HSO4−, SO42−, та їх реакції приєднання, обміну з відповідними константами рівноваги. Було показано, що стабільність молекули H4SiO4 підвищується в ряду HSO4−< CH3SO3− < H2PO4− < SO42−< PO43−< HPO43−. Встановлено, що найбільша стійкість молекули H4SiO4 спостерігається в присутності аніону HPO43−, в якості ліганду. Аналіз розрахунків показав, що з підвищенням ступеня дисоціації лігандів спостерігається нелінійна тенденція зміни енергії зв’язування водневих зв’язків в залежності від природи самого ліганду. Показано, що всі досліджувані кислоти утворюють по два водневі зв’язки з OH-групами ортокремнієвої кислоти. Показані залежності вільної енергії Гіббса від сумарного заряду ортофосфатної кислоти та сумарної енергії зв’язування міжмолекулярних водневих зв’язків від вільної енергії Гіббса реакції утворення кластерів з аніонами ортофосфатної кислоти. Показано особливості зв’язування центру Бренстеда на прикладі кластеру [H5SiO4+ · CH3SO3−].

“…Ligands like phytochelatins (PCs) and metallothioneins also play vital role against As stress by chelating the metalloid and sequestration of the ligandmetal complex to vacuoles thus, counteracting As toxicity. Moreover, osmolyte such as proline, plant growth hormone such as methyl jasmonate, and compounds like sodium nitroprusside (a nitric oxide donor) orthosilicic acid (a source of silicon) and thiourea also help in As detoxification, conferring tolerance against As in plants ( Singh et al 2015;Mousavi et al 2020;Ahmad et al 2020;Dwivedi et al 2020;Upadhyaya et al 2021). Recently, Yadav et al (2021) also reviewed the critical role of internal defence mechanisms to combat As stress in plant.…”

Arsenic (As), the toxic metalloid, is taken up by plant roots and transported to different parts of the plant through transporters of the essential elements due to the structural analogy. The analogy of arsenate (AsV) with phosphate enables As (V) to enter plant through phosphate transporter, while, arsenite (AsIII) which is analogous to silicic acid, is taken up by plants through aquaporins. After the uptake, the different forms of As are translocated to shoot via xylem, imposing toxicity to plants that affect their growth and yield, however this depends on the effective concentration of free As anion at particular cellular organelle /site. To this end, the role of transporters becomes crucial as the central and prime regulator of As movement throughout the plant and in various cellular compartments. It is essential to understand the precise roles of different transporters involved in As uptake and transportation to avoid As accumulation and stress in plant. Therefore, this review discusses the transporters namely, phosphate transporters, nodulin 26-like intrinsic proteins, plasma membrane intrinsic proteins, tonoplast intrinsic proteins, C-type ATP binding cassette transporters, arsenical resistance 3 transporter, inositol transporters, multidrug and toxic compound extrusion transporters, and natural resistance-associated macrophage protein transporters, which are involved in As uptake, sequestration, translocation and efflux in plants, with an emphasis on As stress tolerance through the regulation of expression of the different transporters.
