TLDR
The preliminary conclusions support the primitive status of aluminum hyperaccumulation, which provides an evolutionary model system for the integration of different biological disciplines, such as systematics, ecology, biogeography, physiology, and biochemistry.Abstract:
Aluminum phytotoxicity and genetically based aluminum resistance has been studied intensively during recent decades because aluminum toxicity is often the primary factor limiting crop productivity on acid soils. Plants that grow on soils with high aluminum concentrations employ three basic strategies to deal with aluminum stress. While excluders effectively prevent aluminum from entering their aerial parts over a broad range of aluminum concentration in the soil, hyperaccumulators take up aluminum in their aboveground tissues in quantities above 1000 ppm; that is, far exceeding those present in the soil or in the nonaccumulating species growing nearby. In between these two extremes are indicator species, representing intermediate responses. A list of aluminum hyperaccumulators in angiosperms is compiled on the basis of data in the literature. Aluminum hyperaccumulators include mainly woody, perennial taxa from tropical regions. Recent molecular phylogenies are used to evaluate the systematic and ...read more

TL;DR: The beneficial effects of low doses of Al, Co, Na, sodium, selenium, Se and Se have received little attention compared to toxic effects that typically occur at higher concentrations.

The role of the root apoplast in aluminium-induced inhibition of root elongation and in aluminium resistance of plants: a review
TL;DR: The role of the root apoplast in Al toxicity and resistance, summarizing evidence from our own experimental work and other evidence published since 1995, has been discussed in this article.
REVIEW: PART OF A HIGHLIGHT SECTION ON PLANT -SOIL INTERACTIONS AT LOW PH The role of the root apoplast in aluminium-induced inhibition of root elongation and in aluminium resistance of plants: a review
TL;DR: The binding of Al in the cell wall particularly to the pectic matrix and to the apoplastic face of the plasma membrane in the most Al-sensitive root zone of the root apex thus impairing apoplastics and symplastic cell functions is a major factor leading to Al-induced inhibition of root elongation.

TL;DR: It is found that soil fertility to be the most important predictor, influencing all leaf nutrient concentrations and δ13C and reducing MA, and species that tend to occupy higher fertility soils are characterised by a lower MA and have a higher intrinsic [N], [P], [K], [Mg] and ε13C than their lower fertility counterparts.

TL;DR: One of the major unfortunate consequences of industrialization is soil acidification, and aluminium (Al) is the primary limitation of crop productivity worldwide.

TL;DR: In this article, the authors discuss the relationship between mineral nutrition and plant diseases and pests, and diagnose deficiency and toxicity of mineral nutrients in leaves and other aerial parts of a plant.
Terrestrial higher plants which hyperaccumulate metallic elements. a review of their distribution, ecology and phytochemistry
TL;DR: Phytochemical studies suggest that hyperaccumulation is closely linked to the mechanism of metal tolerance involved in the successful colonization of metalliferous and otherwise phytotoxic soils.
