Abstract :

Soil metal(loid) pollution is a threat to ecological and environmental safety. The vegetation recovery in mining areas is of great significance for protecting soil resources. In this study, (1) we first gathered four types of soils to analyse their contamination degree, including tailings mud (TM), wasteland soil (TS) very near TM, as well as non-rhizosphere soils of pepper (PF) and maize (MF) in a farmland downstream from the TM (about 5 km). Geo-accumulation and potential ecological risk indices indicated that the soil samples were mainly polluted by antimony (Sb), arsenic (As), cadmium (Cd), chromium (Cr), lead (Pb), and copper (Cu) to different degrees. Leachates of TM resulted in increased Sb, As, and Cd accumulation in TS. (2) Then, we sampled six local plants growing in the TS to assess the possibilities of using these plants as recovery vegetation in TS, of which Persicaria maackiana (Regel) Nakai ex T. Mori absorbed relatively high Sb concentrations in the leaves and roots. (3) After that, we collected rhizosphere soil and tissue samples from eight crops on the above farmland to assess their capacities as recovering vegetation of contaminated farmland soil, of which the fruits of maize accumulated the lowest concentrations of most monitored metal(loid)s (except for Pb). Further, we compared the differences in the bacterial community structure of MF, PF, TM, and TS to assess capacities of cultivating pepper and maize to improve soil microbial community structure. The MF displayed the best characteristics regarding the following attributes: (1) the highest concentrations of OMs and total P; (2) the highest OTU numbers and diversity of bacteria; and (3) the lowest abundance of bacteria with potentially pathogenic and stress-tolerant phenotypes.

Genomic Survey of Genes Encoding Major Intrinsic Proteins (MIPs) and Their Response to Arsenite Stress in Pepper (Capsicum annum) SCIE

Abstract&Keyword Cite

Abstract :

Major intrinsic proteins (MIPs) are a super family of proteins that mediate the bidirectional concentration-dependent flux of water in particularly small solutes in fraction and some metalloids across the cell membrane. This article reports the genome-wide study of pepper genes encoding MIPs and their expression analysis. Using a bioinformatics homology search, 48 CAMIPs were identified on the genome of pepper. A total of 48 MIPs were further divided in sub classes as 22 CATIPs, 15 CAPIPs, 10 CANIPs, and 1 CASIP. The 48 Pepper MIP encoding genes were mapped on the 12 pepper chromosomes. CAMIP synteny analysis exhibited 17 duplicated genes, and these were clustered into eight tandem duplicated regions on pepper chromosomes. The tissue-specific expression of MIPs based on RNA-Seq showed certain CANIPs, CATIPs, and CAPIPs were highly expressed in roots, while some CATIPs and CASIPs were expressed in stem as well. As(III), at 0.5 and 1 mM, was applied to pepper plants, where 1 mM significantly reduced leaf chlorophyll content, leaf nitrogen content, and root length. To see which CAMIPs participate in As(III) transport, we tested the response of genes encoding MIPs to As(III) through qRT-PCR. As(III) uptake was observed in both shoot and root samples treated with 0.5 mM and 1 mM As(III) for 12 h and 24 h because of MIPs' quantitative response through qRT-PCR. Most of the MIPs were down-regulated in response to both levels of As(III); besides CANIPs, there were CATIPs and CAPIPs up-regulated in response to higher concentrations of As(III) in the roots and shoot, which suggests the involvement of CAMIPs in the uptake as well as detoxification mechanism in pepper against As(III). Unlike prokaryotes, plant MIPs have diverse selectivity for arsenite and other solutes. Our study provides important insights into the arsenite uptake and detoxification, offering a foundation for further functional and stress-tolerance studies.

Abstract :

为明确改良柚园酸化土壤最佳施肥方式,本研究通过为期两年的蜜柚田间试验,探究农户常规施肥(FFP)、优化施肥(OPT)和施用有机肥(OF)对表层(0~20 cm)和亚表层(20~40 cm)土壤pH值、养分含量、酶活性和土壤微生物群落的影响。结果表明,与FFP相比,OF处理可显著提高土壤pH值和有机质含量,而OPT处理使表层土壤有机质含量显著降低。与FFP相比,OF处理表层土壤蔗糖酶、脲酶、磷酸酶和过氧化氢酶活性显著增加,亚表层土壤脲酶和磷酸酶活性显著增加。与FFP相比,OPT和OF处理增加了土壤细菌多样性,而OF处理降低了真菌多样性。与FFP相比,OPT和OF处理使土壤优势细菌门中变形菌门相对丰度降低,而酸杆菌门相对丰度增加,且对亚表层土壤影响更明显。在优势真菌门中,与FFP相比,OPT处理担子菌门相对丰度降低,而子囊菌门相对丰度有所增加,OF处理则与其相反,且在表层土中效果更为明显。在优势细菌属中,与FFP相比,OPT和OF处理表层土壤慢生根瘤菌相对丰度有所增加,热酸菌相对丰度有所降低。在优势真菌属中,与FFP相比,OPT处理降低了表层土壤中原隐球菌和木霉菌以及亚表层土壤中原隐球菌的相对丰度;OF处理提升了表层土壤中原隐球菌以及亚表层土壤中原隐球菌和木霉菌的相对丰度。综上,优化施肥和施用有机肥可提升土壤pH值,增加微生物多样性,改善土壤微生物群落结构,激发土壤酶活性,为蜜柚树体的生长提供良好的土壤微生态环境,以施用有机肥效果更佳。本研究结果为蜜柚化肥减量与提质增效提供了技术参考。

Genome Deletions and Rewiring of the Transcriptome Underlying High Antimonite Resistance in Achromobacter sp. SMAs-55 SCIE
期刊论文 | 2025 , 26 (1) | INTERNATIONAL JOURNAL OF MOLECULAR SCIENCES
Abstract&Keyword Cite

Abstract :

Microbes have been shown to adapt to stressful or even lethal conditions through displaying genome plasticity. However, how bacteria utilize the ability of genomic plasticity to deal with high antimony (Sb) stress has remained unclear. In this study, the spontaneous mutant strain SMAs-55 of Achromobacter sp. As-55 was obtained under antimonite (Sb(III)) stress. SMAs-55 displayed significantly increased Sb(III) resistance, but it lost the ability to oxidize arsenite (As(III)) by deleting an entire gene island containing genes encoding functions involved in As(III) oxidation, arsenic (As)/Sb resistance and phosphate transport. This study suggests that genetic plasticity has played an important role in As-55 adaption to Sb(III) stress. Transcriptomic analysis found that genes encoding functions involved in capsule polysaccharide synthesis, as well as functions correlated to stress adaptation, ATP production, and metabolism were more strongly expressed in SMAs-55. In addition, a lower intracellular Sb(III) accumulation in SMAs-55 was observed. These findings indicate that reduced uptake through increased capsule biosynthesis was an effective way for SMAs-55 to adapt to an environment displaying high levels of Sb. This study helps us to better understand the evolutionary processes enabling survival of microbes and microbial community in contaminated environments.

Adaptation to metal(loid)s in strain Mucilaginibacter rubeus P2 involves novel arsenic resistance genes and mechanisms SCIE

Abstract&Keyword Cite

Abstract :

Arsenic is a ubiquitous environmental toxi substance that affects human health. Compared to inorganic arsen-icals, reduced organoarsenicals are more toxic, and some of them are recognized as antibiotics, such as meth-ylarsenite [MAs(III)] and arsinothricin (2-amino-4-(hydroxymethylarsinoyl)butanoate, or AST). To date, organoarsenicals such as MAs(V) and roxarsone [Rox(V)] are still used in agriculture and animal husbandry. How bacteria deal with both inorganic and organoarsenic species is unclear. Recently, we identified an envi-ronmental isolate Mucilaginibacter rubeus P2 that has adapted to high arsenic and antinomy levels by triplicating an arsR-mrarsUBact-arsN-arsC-(arsRhp)-hp-acr3-mrme1Bact-mrme2Bact gene cluster. Heterologous expression of mrarsMBact, mrarsUBact, mrme1Bact and mrme2Bact, encoding putative arsenic resistance determinants, in the arsenic hypersensitive strain Escherichia coli AW3110 conferred resistance to As(III), As(V), MAs(III) or Rox(III). Our data suggest that metalloid exposure promotes plasticity in arsenic resistance systems, enhancing host or-ganism adaptation to metalloid stress.

Abstract :

Although the antimicrobial mechanisms of nanomaterials have been extensively investigated, bacterial defense mechanisms associated with AgNPs have not been fully elucidated. We here report that dissolved Ag+ (>0.05 μg mL−1) displayed higher toxicity on cell growth of strain Cupriavidus metallidurans BS1 (GCA_003260185.2) in comparison to 2 and 20 nm AgNPs. The genes necessary for synthesis of distinct abundance and composition of extracellular polymeric substances (EPS) were induced in strain BS1 exposed to Ag stress. This resulted in 20.1% (Ag(I)-EPS) and 24.2% (2 nm AgNPs-EPS) of the C[dbnd]O band integrated intensities being converted into C-OH/C-O-C group vibrations and the Ag-O bond was formed between EPS and 20 nm AgNPs. Meanwhile, the expression of primary resistance genes of the cus, sil and cup operon encoding HME-RND-driven efflux systems as well as a PIB1-type ATPase (CupA) were significantly induced after exposure to Ag(I), 2 and 20 nm AgNPs, respectively. Furthermore, distinct genes involved in biosynthesis pathways responsible for production of EPS were induced to relieve the toxicity of Ag(I), 2 nm and 20 nm AgNPs. This combined action is one potential reason why strain BS1 displayed distinct resistances in response to Ag(I) compared to 2 and 20 nm AgNPs. This work will help in understanding processes important in bacterial defensive mechanisms to AgNPs. © 2024

A Sb(III)-specific efflux transporter from Ensifer adhaerens E-60 SCIE

Abstract&Keyword Cite

Abstract :

Antimony is pervasive environmental toxic substance, and numerous genes encoding mechanisms to resist, transform and extrude the toxic metalloid antimony have been discovered in various microorganisms. Here we identified a major facilitator superfamily (MFS) transporter, AntB, on the chromosome of the arsenite-oxidizing bacterium Ensifer adhaerens E-60 that confers resistance to Sb(III) and Sb(V). The antB gene is adjacent to gene encoding a LysR family transcriptional regulator termed LysRars, which is an As(III)/Sb(III)-responsive transcriptional repressor that is predicted to control expression of antB. Similar antB and lysRars genes are found in related arsenic-resistant bacteria, especially strains of Ensifer adhaerens, and the lysRars gene adjacent to antB encodes a member of a divergent subgroup of putative LysR-type regulators. Closely related AntB and LysRars orthologs contain three conserved cysteine residues, which are Cys17, Cys99, and Cys350 in AntB and Cys81, Cys289 and Cys294 in LysRars, respectively. Expression of antB is induced by As(III), Sb(III), Sb(V) and Rox(III) (4-hydroxy-3-nitrophenyl arsenite). Heterologous expression of antB in E. coli AW3110 (Delta ars) conferred resistance to Sb(III) and Sb(V) and reduced the intracellular concentration of Sb(III). The discovery of the Sb(III) efflux transporter AntB enriches our knowledge of the role of the efflux transporter in the antimony biogeochemical cycle.

Toxicity of antimony to plants: Effects on metabolism of N and S in a rice plant SCIE

WoS CC Cited Count: 3
Abstract&Keyword Cite

Abstract :

Excess antimony (Sb) has been shown to damage plant growth. Rice plants readily absorb a large amount of Sb after a long period of flooding, yet the mechanisms underlying Sb toxicity in plants have not been solved. This study was conducted to explore the effects of Sb on the uptake of N and S, and monitor the concentrations of reduced glutathione (GSH) and enzymes associated with these processes. In addition, we analyzed differentially expressed metabolites (DEMs) correlated with amino acids (AAs) and oligopeptides, specifically DEMs containing sulfur (S), GSH and indole-3-acetic acid (IAA). The results showed that antimonite [Sb(III)] inhibited shoot growth whereas antimonate [Sb(V)] stimulated shoot growth. Interestingly, Sb(III)5/10 enhanced shoot concentrations of total nitrogen (N), NH4+-N [only at Sb(III)10] and S; but reduced the shoot concentrations of NO3-N and soluble protein. Sb(III)5/10 addition significantly increased oxidized glutathione (GSSG) concentration and activities of glutathione peroxidase (GSH-Px) and glutathione S-transferase (GST) but non-significantly affected concentration of reduced glutathione (GSH) and activities of gamma-glutamylcysteine synthetase (GCL) and glutathione reductase (GR), suggesting Sb(III) restricted GSH recycling. Addition of Sb (1) increased the abundance of DEMs associated with lignins, Ca uptake, toxicity/detoxification, and branched chain AAs; (2) decreased the abundance of AAs inclcuding isoleucine (Ile), leucine (Leu), tryptophan (Trp), tyrosine (Tyr) and histidine (His); (3) increased the abundance of arginine (Arg), putrescine (Put) and spermidine (Spd); and (4) affected methylation and acetylation of many AAs, especially acetylation.

Abstract&Keyword Cite

Abstract :

Metals and metalloids are used as weapons for predatory feeding by unicellular eukaryotes on prokaryotes. This review emphasizes the role of metal(loid) bioavailability over the course of Earth's history, coupled with eukaryogenesis and the evolution of the mitochondrion to trace the emergence and use of the metal (loid) prey-killing phagosome as a feeding strategy. Members of the genera Acanthamoeba and Dictyostelium use metals such as zinc (Zn) and copper (Cu), and possibly metalloids, to kill their bacterial prey after phagocytosis. We provide a potential timeline on when these capacities first evolved and how they correlate with perceived changes in metal(loid) bioavailability through Earth's history. The origin of phagotrophic eukaryotes must have postdated the Great Oxidation Event (GOE) in agreement with redox-dependent modification of metal(loid) bioavailability for phagotrophic poisoning. However, this predatory mechanism is predicted to have evolved much later - closer to the origin of the multicellular metazoans and the evolutionary development of the immune systems.

Effects of antimony on synthesis of saccharides and lipids, and enzyme activity associated with synthesis/degradation of saccharides in leaves of a rice plant ESCI
期刊论文 | 2024 , 15 | PLANT STRESS
Abstract&Keyword Cite

Abstract :

Different forms of antimony (Sb) show different toxicities to plants, which are hypothesized to be partially due to the disorders of lipid and saccharide synthesis. Hydroponic experiments were conducted using a rice plant (Yangdao 6) exposed to antimonite (Sb(III)) and antimonate (Sb(V)). We monitored the following (1) saccharide concentration and enzymatic activities associated with synthesis/degradation of sucrose and starch; (2) changes in cell ultrastructure of rice leaves; and (3) differentially expressed metabolites (DEMs) associated with lipids. The results showed that when compared to the control, Sb(III/V) (1) increased the concentrations of starch, soluble sugars, sucrose and fructose as well as the activities of cell-wall binding acid invertase (B-AI) in rice leaves; (2) mainly affected the abundance of unsaturated lipids of fatty acids (FAs), prenol lipids, glycerolipids, and glycerophospholipids, especially for Sb(III); and (3) negatively affected the abundance of DEMs associated with alpha-linolenic acid metabolism and xanthophyll formation. Relative to Sb(V), Sb(III) (1) showed great negative effects on the activities of fructose-1, 6-diphosphatase (FBP), triose-phosphate isomerase (TPI), alpha-glucosidase, and sucrose-phosphate synthase (SPS); (2) significantly narrowed the shape of starch granules and increased the thickness of cell walls; (3) increased numbers and abundance of DEMs associated with toxins (belonging to sphingolipids), flavonoids (polyketides), and biomarkers (corticosteroid hormones); and (4) increased the numbers of FAs whose abundance was upregulated. This study showed a complex regulatory network associated with saccharide synthesis/degradation and lipid constitution in response to Sb toxicity.
