“…Seedlings were grown (10-12 days) under growth chamber conditions (16/8 light period, temperature 25 ± 1 ° C). The explants (1.0 cm of the hypocotyl) were grown in a pre-prepared MS medium and incubated in a growth chamber for a month (Farghaly et al 2021).…”

“…Among the compounds participate in the development of adaptive actions, there are important roles played by components of the lipoxygenase (LOX) pathway that possess the key signaling system properties (Rejeb et al 2014). Recently, in tomatoes, accumulation of B, H 2 O 2 , lipid peroxidation in tissues resulting from EB has been stated (Kaya et al 2020;Farghaly et al 2021).…”

“…Phenolics have been harnessed in many applications such as plant growth promotion, antioxidant, allelochemical and bioremediation (Bujor et al 2015). Benzoate (BA), gallate (GA), and salicylate (SA) are phenolic compounds involved in the regulation of growth and development of plants, and their responses to (a)biotic stress factors (Khan et al 2015;Farghaly et al 2021). Senaratna et al (2003) stated that BA is known to provide abiotic stressor tolerance similar to that reported for SA.…”

“…BA has been proven to provide resistance against extreme-temperature ( Senaratna et al 2003), drought (Anjum et al 2013), heavy metals (Pan-pan et al, 2020), and excess boron (Farghaly et al 2021). In plants, gallate's participation in defense against abiotic stress is not yet largely known, and it is only known to reduce the effect of ozone stress (Rudolphi-Skórska and Sieprawska 2016), alleviate cold stress (Oz dan-Konakci et al 2019), increase tolerance against Cd and Cu stress (Oz dan-Konakci and Kabakci 2020; Yetişsina and Kurtb 2020), and relief of EB stress (Farghaly et al 2021). SA plays a critical role in controlling many physiological activities and plant tolerance to various environmental stresses (Khan et al 2019).…”

The participation of benzoate (BA), gallate (GA), and salicylate (SA) in various biochemical and physiological processes in plants under conditions of excessive boron (EB) is largely unknown to date. Here, the relationships between phenolic acids (PAs) and the regulation of redox-enzymes, the ultrastructure of cells, and boron forms in the mitigation of EB-induced oxidative stress within tomato calli were studied. Tomato calli were exposed to 2 mM boron (B) in the presence or absence of three concentrations of benzoate, gallate, and salicylate. The data showed that different concentrations of PA counteracted the inhibition of growth and oxidative stress of EB stress by reducing hydrogen peroxide (H2O2) production, lipoxygenase (LOX) activity, boron accumulation forms, cell wall thickening, and moderate concentrations were the most effective. Applications of PAs reduced the catalytic impacts of EB on superoxide dismutase (SOD) and catalase (CAT) activity. Likewise, benzoate and gallate increased the influences of EB stimulation on peroxidase (POD) and ascorbate peroxidase (APX) activities; whereas, SA reduced these effects on both enzymes. PA treatments enhanced the insignificant catalytic effect of EB on the activity of phenylalanine ammonia-lyase (PAL), as well as the stimulation of the negative influence of EB on polyphenol oxidase (PPO) activity. The findings highlight that PAs play an important role in alleviating EB stress in tomato plants by regulating redox enzymes, B-accumulation forms, and cell wall thickening. This study provides new perspectives for strategies related to excess boron tolerance in tomato plants and thus can be used as plant growth promoters.
