Abstract:
... AIMS: Cerrado woody species are divided into a small group of aluminum (Al)-accumulating species and the rest of the woody species. Both groups grow well on acidic and Al-rich soils. We found a Cerrado remnant growing on a calcareous soil with high calcium (Ca) and low Al saturations (m%). We checked whether Al deposition differs between leaf veins and leaf blade, and predicted that plants grown o ...

Abstract:
... BACKGROUND AND AIMS: Although aluminum (Al) exclusion via root exudation of organic matters is a common resistance mechanism adopted by many plant species, whether root exudation of benzoxazinoids, such as hydroxamic acids (HAs), confers Al resistance remains unclear. METHODS: We performed physiological characterization for an Al-resistant maize cultivar TY and a sensitive maize cultivar ZD. RESUL ...

Abstract:
... AIMS: Dicranopteris linearis is a fern that accumulates unusually high concentrations (up to 0.3% dry weight) of rare earth elements (REEs) in China. Previously, we reported that D. linearis accumulates high concentrations of aluminium (Al) and silicon (Si) in the fronds, but the interactions between these elements and REEs were unknown. METHODS: In this study, a range of analytical techniques, in ...
