Cadmium accumulation is enhanced by ammonium compared to nitrate in two hyperaccumulators, without affecting speciation
Highlight Supply of NH4 + compared with NO3 − increased plant Cd uptake, translocation and accumulation in Carpobrotus rossii and Solanum nigrum. Cd-S was the dominant Cd species, with Cd beingExpand

Silver sulfide nanoparticles (Ag2S-NPs) are taken up by plants and are phytotoxic
Abstract Silver nanoparticles (NPs) are used in more consumer products than any other nanomaterial and their release into the environment is unavoidable. Of primary concern is the wastewater streamExpand

Synchrotron-Based Techniques Shed Light on Mechanisms of Plant Sensitivity and Tolerance to High Manganese in the Root Environment1[OPEN]
Mn toxicity results from apoplastic accumulation in soybean leaves, while tolerance occurs through vacuolar Mn(II) sequestration in two lupin species and oxidation to Mn(III) in trichomes ofExpand

Ammonium-based fertilizers enhance Cd accumulation in Carpobrotus rossii grown in two soils differing in pH.
Nitrogen fertilization has been shown to improve Cd uptake by plants but there is little information on the effect of N form. This study examined the effects of N form on Cd bioavailability andExpand

Absorption of foliar-applied Zn in sunflower (Helianthus annuus): importance of the cuticle, stomata and trichomes
Background and Aims The pathways whereby foliar-applied nutrients move across the leaf surface remain unclear. The aim of the present study was to examine the pathways by which foliar-applied ZnExpand

Absorption of foliar-applied Zn fertilizers by trichomes in soybean and tomato
Leaf trichomes are not part of the primary pathway through which foliar-applied Zn fertilizer moves across the leaf surface in soybean and tomato.

Manganese distribution and speciation help to explain the effects of silicate and phosphate on manganese toxicity in four crop species.
Soil acidity and waterlogging increase manganese (Mn) in leaf tissues to potentially toxic concentrations, an effect reportedly alleviated by increased silicon (Si) and phosphorus (P) supply. EffectsExpand

Contrasting effects of organic amendments on phytoextraction of heavy metals in a contaminated sediment
Background and aimsSoil amendments are often added to polluted soils to increase phytoremediation efficiency. Here we investigated the potential of a range of organic amendments for phytoextractionExpand

Cadmium reduces zinc uptake but enhances its translocation in the cadmium-accumulator, Carpobrotus rossii, without affecting speciation
Background and aimsInteractions between Cd and Zn occur in soils and plants but are inconsistent. This study examined how Cd/Zn interactions influence the growth of Carpobrotus rossii (Haw.) and theExpand

Sodium chloride decreases cadmium accumulation and changes the response of metabolites to cadmium stress in the halophyte Carpobrotus rossii
Background and Aims Salinity affects the bioavailability of cadmium (Cd) in soils and Cd accumulation in plants, but the associated mechanisms remain unclear. This study aimed to assess the metabolicExpand
