Role of phosphate on uptake of antimonate coupled with upgrading Salvia spinosa L. tolerance to antimony toxicity
Aims
Antimonate (Sb(V)) toxicity to plant health is well-known, while a little is known about its uptake mechanism. The application of phosphate fertilizer is a common practice in agriculture. We aimed to study the interaction of phosphorus (P) and Sb(V) in Salvia spinosa L.
Methods
The effects of 50 and 300 μM K2HPO4 on Sb(V) uptake (0 or 50 μM) were investigated for 2, 4 and 6 days in a hydroponic system.
Results
K2HPO4 (P) treatment increased Sb(V) uptake in Salvia. Sb(V) was mainly accumulated in roots, by 12 times higher than that in shoot. The addition of 300 μM K2HPO4 enhanced Sb accumulation by 428 and 26 mg Kg−1 in roots and shoot, respectively, in 6 day-treated plants. Irrespective of the increase in Sb(V) content in the K2HPO4-treated plants, the H2O2 and MDA contents significantly reduced to less than Sb treatment alone, which can be connected to the observed increase in phenols, flavonoids, and activity of catalase, ascorbate peroxidase and superoxide dismutase. Besides, P treatments suppressed the adverse effects of Sb(V) stress on sugars, proteins, the lipid membrane and subsequently on plant growth.
Conclusions
The improvement in Sb(V) uptake and accumulation in plant organs is important from the view of Sb(V) removal from the environment, which was achieved in a Sb metallicolous type of S. Spinosa under P treatment. Taken together, P fertilizers can be recommended as an easy and effective practice to enhance uptake of Sb, in parallel with improving plant tolerance to Sb(V) toxicity.
期刊介绍：
Plant and Soil publishes original papers and review articles exploring the interface of plant biology and soil sciences, and that enhance our mechanistic understanding of plant-soil interactions. We focus on the interface of plant biology and soil sciences, and seek those manuscripts with a strong mechanistic component which develop and test hypotheses aimed at understanding underlying mechanisms of plant-soil interactions. Manuscripts can include both fundamental and applied aspects of mineral nutrition, plant water relations, symbiotic and pathogenic plant-microbe interactions, root anatomy and morphology, soil biology, ecology, agrochemistry and agrophysics, as long as they are hypothesis-driven and enhance our mechanistic understanding. Articles including a major molecular or modelling component also fall within the scope of the journal. All contributions appear in the English language, with consistent spelling, using either American or British English.
