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: Antimony (Sb) is locally found at potentially toxic concentrations in mineralized soils, usually together with arsenic (As). However, local adaptation of plant populations to Sb toxicity has never been shown thus far. Here we compared Sb tolerance and accumulation between a non-metallicolous (NM) population of Salvia spinosa, and a con-specific metallicolous (M) population from a strongly Sb ...
