Research, industry and conservation context for Cadmium hyperaccumulation and phytoremediation.
A Hunan field trial inverts the standard paddy rule — instead of flooding to keep cadmium out of grain, deliberately timed drying oxidises CdS, acidifies the rhizosphere and lets a high-Cd rice cultivar pull 474.56 g Cd ha⁻¹ out of the soil in one season, at removal efficiency comparable to dedicated hyperaccumulators.
Read the analysis →A foliar quercetin spray changes cadmium partitioning in amaranth by priming the phenylpropanoid/flavonoid pathway and the GSH–AsA antioxidant cycle, raising shoot enrichment well above the Cd-hyperaccumulator threshold in a pot experiment.
Read the analysis →A new FAST-TRACE transient expression system lets researchers dissect the SpHMA3 promoter in the Cd/Zn hyperaccumulator Sedum plumbizincicola in days, pinpointing a MYB transcription factor that activates it ~3.7-fold.
Read the analysis →Polystyrene nanoplastics act as unintended cadmium carriers in soil, increasing exchangeable and carbonate-bound Cd and raising shoot Cd accumulation in Sedum alfredii — but the gain comes with oxidative stress and depleted Zn, Cu, and Mn.
Read the analysis →Four endophytes isolated from the Cd/Zn hyperaccumulator Sedum alfredii, assembled into a synthetic community, reprogram Brassica juncea to extract more cadmium while also growing larger—breaking the usual growth-dilution trade-off.
Read the analysis →A pot study shows that co-inoculating the Cd/Zn hyperaccumulator Sedum plumbizincicola with an arbuscular mycorrhizal fungus and a phosphate-solubilising bacterium raises shoot Cd accumulation by 182% by simultaneously increasing biomass and rhizosphere Cd bioavailability.
Read the analysis →Two weedy accumulators planted between cacao trees are credited with a near-total one-season soil-cadmium crash, but a mass balance shows the plants removed on the order of one percent of what vanished, and cacao-bean cadmium, the number that actually gates the crop out of Europe, hardly changed.
Read the analysis →A metallicolous Lotus corniculatus keeps zinc, lead and cadmium out of its shoots by root exclusion and a rerouted redox economy — the exact profile you want for phytostabilisation, and a quiet hazard in a forage legume, because the little cadmium that still gets through exceeds the EU animal-feed limit.
Read the analysis →Phosphorus fertiliser raised amaranth's cadmium removal by up to 140%, but mostly by growing more plant, not by freeing more metal — and the single strongest lever works by acidifying the very soil it is meant to clean.
Read the analysis →A trace of cadmium makes this accumulator put on 30% more shoot by rerouting carbon from starch into sucrose — a possible yield lever for the slow end of a cleanup, and a warning that a thriving stand is not a clean soil.
