“…One of the possible reasons explaining the stimulation of plant growth induced by Al is the promotion of nutrient uptake. In hyperaccumulator plants, Al can stimulate or have no effect on essential nutrient uptake ( Malta et al, 2016 ). In different plant species, nitrogen (N), phosphorous (P), and potassium (K) uptake has been considered the mechanism responsible for the stimulation of root growth induced by Al ( Osaki et al, 1997 ).…”

Aluminum (Al) is the most abundant metal in the earth’s crust, but its availability depends on soil pH. Despite this abundance, Al is not considered an essential element and so far no experimental evidence has been put forward for a biological role. In plants and other organisms, Al can have a beneficial or toxic effect, depending on factors such as, metal concentration, the chemical form of Al, growth conditions and plant species. Here we review recent advances in the study of Al in plants at physiological, biochemical and molecular levels, focusing mainly on the beneficial effect of Al in plants (stimulation of root growth, increased nutrient uptake, the increase in enzyme activity, and others). In addition, we discuss the possible mechanisms involved in improving the growth of plants cultivated in soils with acid pH, as well as mechanisms of tolerance to the toxic effect of Al.

“…The metal complexing property of these compounds and their release into the rhizosphere has been also described as an attempt by the plants to assure a balanced uptake in cases of nutrient shortage or to limit the availability of toxic elements (Jones, 1998;Pallar es et al, 2005;Malta et al, 2016). Particularly in the case of intercropping, the phenomenon could mean that the inefficient plant species can take advantage of the adaptive response of the efficient one, as described for the intercropping of Morus alba L and Pteris vittata L in arsenic contaminated soil (Wan et al, 2017) or for citrus plants and cover crop species grown in soil with Fe shortage (Cesco et al, 2006).…”

“…[13], Melastomataceae ( Melastoma malabathricum ) [14], and Vochysiaceae (Qualea grandiflora , Callisthene major and Vochysia pyramidalis ) [15] families that can accumulate up to 10,000 mg Al Kg −1 in their leaves [14]. These species possess mechanisms for Al exclusion and/or internal complexation, permitting survival even at high Al concentrations [16,17]. Some Al-tolerant plants may accumulate between 1000 and 15,000 mg of Al 3+ per kg of dry matter [18,19].…”

Native Cerrado plants are exposed to soils with low pH and high availability of Al. In this study, we measured the Al content in adult plants, and investigated the effects of various Al doses on germination and early development of Eugenia dysenterica plants. For germination tests, the seeds were soaked in Al solution and evaluated for twenty days in growth chambers. In a second experiment, young plants were cultivated in hydroponic systems with various Al concentrations to evaluate the morphological, anatomical and physiological characteristics of E. dysenterica. Anatomical changes and low germinative vigor were observed in seeds germinated in 600 and 800 μmol Al3+ L−1. In the hydroponic system, 200 μmol Al3+ L−1 stimulated root growth in young plants. The activity of antioxidant enzymes and the accumulation of phenolic compounds were greatest at the highest Al doses, preventing changes in gas exchange and chlorophyll a fluorescence. Starch grain accumulation was noted in plant cells exposed to 200 and 400 μmol Al3+ L−1. Adult E. dysenterica trees also accumulated Al in leaves, bark and seeds. These data suggest that E. dysenterica is tolerant to Al.
