Abstract Heavy metal contamination is an urgent ecological governance problem in mining areas. In order to seek for a green and environmentally friendly reagent with better plant restoration effect solve the of low efficiency heavy pollution soil. this study, we evaluated effects three biodegradable chelating agents, namely citric acid (CA), fulvic (FA) polyaspartic (PASP), on physicochemical properties copper tailings, growth ryegrass ( Lolium perenne L.) accumulation therein. The results showed that agent application improved increased biomass enriched more Cu Cd tailings. control group, main existing forms were oxidizable state, followed by residual, weak soluble reducible states. After CA, FA or PASP application, converted from residual states states, whose bioavailability tailings thus enhanced. Besides, incorporation extraction efficiencies as manifested root stem contents 30.29–103.42%, 11.43–74.29%, 2.98–110.98% 11.11–111.11%, respectively, comparison group. presence multiple metals, selectivity regarding metals PCA analysis revealed CA-4 PASP-7 treatment had great remediation potentials against increases 90.98% 74.29% compared CK

Chloroplast genomes for 3 Bidens plants endemic to China (Bidens bipinnata Linn., pilosa and alba var. radiata) have been sequenced, assembled annotated in this study distinguish their molecular characterization phylogenetic relationships. The chloroplast are typical quadripartite structure with two inverted repeat regions separating a large single copy region small region, ranged from 151,599 154,478 bp length. Similar number of SSRs long repeats were found Bidens, wherein mononucleotide (A/T), forward palindromic the most abundance. Gene loss clpP psbD, IR expansion contraction detected these plants. It seems that ndhE, ndhF, ndhG, rpl32 under positive selection while majority genes purifying selection. Phylogenetic analysis revealed clustered together further formed molophyletic clade other species, indicating might be radiation adaptive changing environment world-widely. Moreover, mutation hotspot silico PCR indicated inter-genic ndhD-ccsA, ndhI-ndhG, ndhF-rpl32, trnL_UAG-rpl32, ndhE-psaC, matK-rps16, rps2-atpI, cemA-petA, petN-psbM candidate markers identification This may provide useful information genetic diversity species.

Considering the detrimental impact of heavy metals on agricultural soils, in situ remediation technology has gained considerable attention worldwide. Green materials have emerged as a promising option for enhancing plant-mediated contaminated soils. In this study, bacteria capable mobilising cadmium (Cd) and promoting plant growth were screened isolated. A synergistic system was established by combining bone meal chitosan soil amendments with Cd-mobilising to improve extraction available Cd from soils plants. The highest accumulation observed + bacteria, which increased 131.81% when compared control group (CK). content 52.31% CK. Fourier-transform infrared spectroscopy X-ray photoelectron results revealed that organic compounds, such hydroxyl carboxyl groups, aliphatic compounds crucial Cd. activation occurred through substitution protons functional groups chelation, leading formation chelates Cd2+ turn, facilitating mobilisation soil. incorporation into phytoremediation strategies can enhance ability mobilise Cd, thereby increasing effectiveness phytoremediation.

Soil cadmium (Cd) pollution is a critical environmental issue that requires urgent remediation. Sedum alfredii Hance, known for its high biomass, strong stress tolerance, and suitability harvesting, serves as an excellent hyperaccumulator. This study used field experiments to investigate the enhancement of Cd phytoremediation in soil using three activators: citric acid (CA), malic (MA), polyaspartic (PASP). The results showed biomass was increased by 8.95–28.37% addition these activators, significantly boosting accumulation efficiency, with average removal rate increase 12%. Among all CA exhibited most substantial effect, enrichment coefficients 36.26% 11.56% aboveground parts roots alfredii, respectively, 21.15% rate. Although PASP had less pronounced effect on uptake, decreases 15.25% 35.34% roots, it impacted speciation activation 20%.
