“…In addition, NH + 4 can be absorbed through aquaporins, non-selective cation transporters and K transporters, increasing the risk of exposure to excess NH + 4 concentrations (Bittsánszky et al, 2015). In this context, the toxicity of NH + 4 results in a lower accumulation of cations such as K, Ca and Mg (Nasraoui-Hajaji & Gouia, 2014), as observed in this study (Figure 1c-e). Since K + and NH + 4 are very similar in terms of valence and ionic radius, they may not be distinguishable by the membrane-bound carrier.…”

“…For example, accumulator plants, which actively absorb Si, exhibit Si contents greater than 10 g/kg while intermediate plants, which passively absorb Si, maintain Si contents between 5 and 10 g/kg and Si‐excluding plants have Si contents below 5 g/kg (Ma & Takahashi, 2002). The benefits of Si in cotton plants were to alleviate boron deficiency and toxicity (Souza Junior et al, 2019) and nickel toxicity (Khaliq et al., 2016).

Ammonium-based fertilizers (urea, anhydrous NH 3 , (NH 4 ) 2 SO 4 and NH 4 NO 3 ) comprise the most commonly used forms of N applied in agriculture. While many soils can retain an abundance of cations such as NH + 4 , due to the typically negative charges on soil particle surfaces, large amounts of N are lost via the nitrification of NH 3 to NO − 3 , followed by leaching and runoff of this poorly soil-bound anion. For this reason, several strategies have been put forward to curb agricultural N losses, including the use of synthetic nitrification inhibitors (Coskun et al., 2017;Kawakami et al., 2013). The nitrification inhibitors contribute to increasing the supply of N in the form of NH + 4 , one of the forms of N absorbed by plants, in addition to NO − 3 . For example, three days after soil fertilization with urea (225 kg/ha of N), the NH + 4 in the soil solution was 0.44 and 1.74 mmol/L, without and with nitrification inhibitor, respectively (Kirschke et al., 2019).In relation to NO − 3 , NH + 4 has the advantage of a lower energy cost necessary to be incorporated into organic compounds, which can lead to increased crop yields. However, NH + 4 has the disadvantage of being toxic depending on its concentration in the culture medium and the tolerance of the plant (Salsac et al., 1987). Among the consequences of NH + 4 toxicity, the decrease in the accumulation of cations such as K, Ca and

“…During the last decade, researchers have assessed the effects of Si under excess boron (B), mainly in soil-grown cereals [ 64 , 65 , 66 , 67 ]. A recent study showed that Si application alleviated the harmful effects of B deficiency and toxicity in cotton by different modes of Si application [ 68 ]. The authors showed that foliar Si application was effective under B deficiency, by improving the photosynthesis-related parameters, while root application of Si restricted B transport into shoots under B toxicity.…”

It has been long recognized that silicon (Si) plays important roles in plant productivity by improving mineral nutrition deficiencies. Despite the fact that Si is considered as ‘quasi–essential’, the positive effect of Si has mostly been described in resistance to biotic and tolerance to abiotic stresses. During the last decade, much effort has been aimed at linking the positive effects of Si under nutrient deficiency or heavy metal toxicity (HM). These studies highlight the positive effect of Si on biomass production, by maintaining photosynthetic machinery, decreasing transpiration rate and stomatal conductance, and regulating uptake and root to shoot translocation of nutrients as well as reducing oxidative stress. The mechanisms of these inputs and the processes driving the alterations in plant adaptation to nutritional stress are, however, largely unknown. In this review, we focus on the interaction of Si and macronutrient (MaN) deficiencies or micro-nutrient (MiN) deficiency, summarizing the current knowledge in numerous research fields that can improve our understanding of the mechanisms underpinning this cross-talk. To this end, we discuss the gap in Si nutrition and propose a working model to explain the responses of individual MaN or MiN disorders and their mutual responses to Si supplementation.

“…In addition, B deficiency decreases the transport of photoassimilates from leaves to flowers and fruits, impairing flower, seed and fruit formation [ 8 ]. Although B plays a vital role in plant reproduction [ 9 ], micronutrient deficiency can also impair the vegetative development of cotton plants [ 10 ]. This developmental impairment is due to the boron’s function in the cell wall structure, as well as due to its biological function in the metabolism of nucleic acids, proteins, phenols and in the functionality of the plasma membrane and sugar transport [ 11 – 14 ], cell elongation, and protein synthesis, resulting in increased cell division [ 15 ].…”

Addition of silicon to boron foliar spray in cotton plants modulates the antioxidative system attenuating boron deficiency and toxicity

Background Boron (B) nutritional disorders, either deficiency or toxicity, may lead to an increase in reactive oxygen species production, causing damage to cells. Oxidative damage in leaves can be attenuated by supplying silicon (Si). The aim of this study was to assess the effect of increasing foliar B accumulation on cotton plants to determine whether adding Si to the spray solution promotes gains to correct deficiency and toxicity of this micronutrient by decreasing oxidative stress via synthetizing proline and glycine-betaine, thereby raising dry matter production. Results B deficiency or toxicity increased H2O2 and MDA leaf concentration in cotton plants. H2O2 and MDA leaf concentration declined, with quadratic adjustment, as a function of increased leaf B accumulation. Proline and glycine-betaine leaf concentration increased under B-deficiency and B-toxicity. In addition, production of these nonenzymatic antioxidant compounds was greater in plants under toxicity, in relation to deficient plants. Adding Si to the B spray solution reduced H2O2 and MDA concentration in the plants under nutrient deficiency or toxicity. Si reduced H2O2, primarily in B-deficient plants. Si also increased proline and glycine-betaine concentration, mainly in plants under B toxicity. Dry matter production of B-deficient cotton plants increased up to an application of 1.2 g L− 1 of B. The critical B level in the spray solution for deficiency and toxicity was observed at a concentration of 0.5 and 1.9 g L− 1 of B, respectively, in the presence of Si, and 0.4 and 1.9 g L− 1 of B without it. In addition, the presence of Si in the B solution raised dry matter production in all B concentrations evaluated in this study. Conclusion Our findings demonstrated that adding Si to a B solution is important in the foliar spraying of cotton plants because it increases proline and glycine-betaine production and reduces H2O2 and MDA concentration, in addition to mitigating the oxidative stress in cotton plants under B deficiency or toxicity.
