“…Boron has been placed on the list of essential micronutrients and is considered an essential element for plant growth and the development of higher crop plants [ 18 , 29 , 30 , 31 ]. The deficiency of B in plants leads to many deformities in plants, such as root growth inhibition; the induction of chlorotic disorders in leaves; a reduction in yield; and the impairment of the cellular components, structure, and composition of the cell wall [ 31 , 32 , 33 ]. Similarly, the alleviation of Al3+-induced stress by the exogenous treatment of B in different plants has been reported previously by many researchers in different plants [ 29 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 ].…”

The current study aimed to understand the synergistic impacts of silicon (Si; 1.0 mM) and boron (B; 10 µM) application on modulating physio-molecular responses of date palm to mitigate aluminum (Al3+; 2.0 mM) toxicity. Results revealed that compared to sole Si and B treatments, a combined application significantly improved plant growth, biomass, and photosynthetic pigments during Al toxicity. Interestingly, Si and B resulted in significantly higher exudation of organic acid (malic acids, citric acids, and acetic acid) in the plant’s rhizosphere. This is also correlated with the reduced accumulation and translocation of Al in roots (60%) and shoots (56%) in Si and B treatments during Al toxicity compared to in sole Al3+ treatment. The activation of organic acids by combined Si + B application has significantly regulated the ALMT1, ALMT2 and plasma membrane ATPase; PMMA1 and PMMA3 in roots and shoots. Further, the Si-related transporter Lsi2 gene was upregulated by Si + B application under Al toxicity. This was also validated by the higher uptake and translocation of Si in plants. Al-induced oxidative stress was significantly counteracted by exhibiting lower malondialdehyde and superoxide production in Si + B treatments. Experiencing less oxidative stress was evident from upregulation of CAT and Cyt-Cu/Zn SOD expression; hence, enzymatic activities such as polyphenol oxidase, catalase, peroxidase, and ascorbate peroxidase were significantly activated. In the case of endogenous phytohormones, Si + B application demonstrated the downregulation of the abscisic acid (ABA; NCED1 and NCED6) and salicylic acid (SA; PYL4, PYR1) biosynthesis-related genes. Consequently, we also noticed a lower accumulation of ABA and rising SA levels under Al-stress. The current findings illustrate that the synergistic Si + B application could be an effective strategy for date palm growth and productivity against Al stress and could be further extended in field trails in Al-contaminated fields.

“…Plant root growth inhibition is the first symptom of Al poisoning in plants, occurring within minutes to hours of Al exposure (micro molar concentration) [4]. The root elongation inhibition is usually employed for Al resistance screening in plant species and cultivars, which is positively correlated with Al accumulation [5].…”

Aluminum (Al) toxicity is one of the factors limiting alfalfa production on acid soils. This study aims to investigate the different mechanisms in growth, Al content, pectin content, pectin methylesterase (PME) and the degree of pectin methyl-esterification (DM) in the two root segments of different ecotypes alfalfa during the time of Al stress. It was found interesting that lower root elongation and higher Al content were observed in the Al-sensitive ecotype compared to the Al-resistant ecotype of alfalfa. The Al accumulation increased with the increased of stress time. Meanwhile, the pectin and PME activity of cell wall significantly increased. While DM in Al-sensitive ecotype decreased, more free pectin acid residues on the cell wall of Al-sensitive ecotype. The Al content was higher in 0-5 mm root segments and the cell wall for both materials. The increase in pectin content and PME activity along with the decrease in DM in this segment could determine the alfalfa sensitivity to Al more effectively. The correlation analysis showed that there was a relationship between Al content, pectin content, PME activity of cell wall and DM. The different temporal dynamics and spatial differences caused the increase of Al content, pectin content and cell wall PME activity, changes of DM under Al toxicity cooperates to determine the difference of Al resistance that confers different ecotypes of alfalfa.

“…The presence of heavy metals can not only change the soil enzyme system, such as urease, protease, catalase, phosphatase, and β-glucosidase [42,43], but also antioxidant enzymes in plants [2]. Higher antioxidant enzyme activity has been widely perceived to reduce ROS accumulation in plants under different stress [44][45][46]. Many studies have proposed that the activated antioxidant enzyme system plays an essential role in improving plant Cd resistance and acts as ROS scavengers [47].…”

Rapeseed (Brassica napus L.) is a nutritious vegetable, while cadmium (Cd) pollution threatens the growth, productivity, and food security of rapeseed. By studying the effects of iminodisuccinic acid (IDS), an easily biodegradable and environmental friendly chelating agent, on Cd distribution at the organ and cellular level, we found IDS promoted dry matter accumulation of rapeseed and increased the contents of photosynthetic pigment in leaves. Inhibited root-shoot Cd transport resulted in higher activity of antioxidant enzymes and decreased hydrogen peroxide (H2O2) and malondialdehyde (MDA) accumulation in leaves, which indicated that IDS contributed to alleviating Cd-caused oxidative damage in leaf cells. Additionally, IDS increased Cd subcellular distribution in cell wall (CW), especially in covalently bound pectin (CSP), and relieved Cd toxicity in organelle of leaves. IDS also enhanced demethylation of CSP. The Cd content in CSP, demethylation degree, and pectin methylesterase activity of CSP increased by 37.95%, 13.34%, and 13.16%, respectively, while IDS did not change the contents of different CW components. The improved Cd fixation in leaf CW was mainly attributed to enhance demethylation of covalently bound pectin (CSP) and Cd chelation with CSP.
