“…Aluminum-induced alterations to the plant cell cause plant roots grown under conditions of Al toxicity to become atrophied and brittle, experience fine-scale changes, and present increased cell wall rigidity and thickness, and changes in membrane transport proteins are also observed (Meharg 1993;Kochian et al 2004;Vitorello et al 2005;Zobel et al 2007;Kopittke et al 2008). Therefore, a root developed in the presence of Al experiences reduced growth and presents less efficient water and nutrient uptake, especially in the deeper soil layers (Mistro et al 2001;Barceló and Poschenrieder 2002;Kochian et al 2004;Mariano and Keltjens 2005;Olivares et al 2009;Silva et al 2010;Freitas et al 2017). Furthermore, as a secondary effect, Al induces less chlorophyll production in the plant shoots and decreases the photosynthetic rate (Zhang et al 2007;Ali et al 2008;Aftab et al 2010;Shen et al 2014).…”

Aims This study aimed to determine the capacity of Si to mitigate Al toxicity in upland rice plants (Oryza sativa L.) by evaluating plant growth and the Si and Al uptake kinetics. Methods Plants were grown for 40 days, after which the Si and Al uptake kinetics (Cmin, Km and Imax) were analyzed. Then, the shoots and roots were separated, and the dry matter, root morphology and Si and Al concentration and accumulation in the plant were evaluated. Results Aluminum decreased plant growth and the Si uptake capacity by decreasing the root growth and Si transport system efficiency in the upland rice roots (> Km and > Cmin). Silicon mitigated Al toxicity in the upland rice plants by decreasing Al transport to the plant shoots, although it did not reduce the Al uptake rate (Imax). Si treatment increased the growth of upland rice plant shoots grown in the presence of Al without influencing the root growth. The alleviation of Al toxicity by Si is more evident in the susceptible upland rice cultivar Maravilha. Conclusions Silicon mitigated Al toxicity in the upland rice plants by decreasing Al transport to the plant shoots but did not reduce the Al uptake rate by roots.

“…In Camellia japonica , 1000 µM of Al induced a decrease in the endogenous concentrations of Mg and Ca [ 27 ]. According to de Freitas et al [ 50 ], in upland rice treated with 1110 and 1480 µM of Al, the contents of K, Ca, Fe and Zn were strongly reduced because of the competition of Al and minerals for the sites of the uptake on influx channels, and the transporters of mono- and divalent cations. In reality, the interaction of Al with plasma membrane modifies its structure [ 48 ].…”

Trace metal element (TME) pollution is a major threat to plants, animals and humans. Agricultural products contaminated with metals may pose health risks for people; therefore, international standards have been established by the FAO/WHO to ensure food safety as well as the possibility of crop production in contaminated soils. This study aimed to assess the accumulating potential of aluminum and barium in the roots, shoots and fruits of Abelmoschus esculentus L., and their effect on growth and mineral nutrition. The content of proline and some secondary metabolites was also evaluated. After treating okra plants with aluminum/barium (0, 100, 200, 400 and 600 µM) for 45 days, the results showed that Al stimulated the dry biomass production, whereas Ba negatively affected the growth and the fructification yield. The okra plants retained both elements and exhibited a preferential accumulation in the roots following the sequence: roots ˃ shoots ˃ fruits, which is interesting for phytostabilization purposes. Al or Ba exposure induced a decline in mineral uptake (K, Ca, Mg, Zn and Fe), especially in roots and shoots. In order to cope with the stress conditions, the okra plants enhanced their proline and total phenol amounts, offering better adaptability to stress.

“…This may also be explained by the inhibition of H + -ATPase activity, which may prevent the formation and maintenance of the proton gradient (Bojórquez-quintal et al 2017). The decrease in RNO3activity may be associated with the potential of aluminum to interfere with processes involved in absorption, transport, and nutrient use (Freitas et al 2017).…”

Due to rainfall and high temperatures, the Amazonian soil undergoes changes in its source material and leaching of base cations. This results in deep, infertile, and acidic soil. Aluminum present in acidic soil impairs plant growth and development by inhibiting root formation, enzymatic reactions, absorption, transport, and nutrient utilization. This study aimed to evaluate the effects of aluminum dosage on the metabolism of the oil palm Elaeis guineensis Jacq. The study was conducted in a greenhouse at the Federal Rural University of Amazonia. The experimental design was randomized, with five replications, in which dosages of 0, 10, 20, 30, and 40 mg L-1 aluminum chloride (AlCl3.6H2O) were administered. Electrolyte leakage, nitrate, nitrate reductase, free ammonium, soluble amino acids, proline content, and soluble proteins were analyzed in the leaves and roots of the oil palm. The highest concentration of aluminum was found in the roots. AlCl3 treatment at 40 mg L-1 increased electrolyte leakage, nitrate, ammonium, and proline concentrations in the roots, and amino acid concentrations in both the leaves and roots. Furthermore, a decrease in nitrate reductase enzyme activity was observed in the roots. This study demonstrates that the oil palm has mechanisms of tolerance to aluminum toxicity.
