Abstract
Agricultural systems are under increasing pressure from declining environmental conditions, a growing population, and changes in consumer preferences, resulting in widespread malnutrition-related illnesses. Improving plant nutritional content through biotechnology techniques such as synthetic biology is a promising strategy to help combat hidden hunger caused by the lack of affordable and healthy foods in human diets. Production of compounds usually found in animal-rich diets, such as vitamin D or omega-3 fatty acids, has been recently demonstrated in planta. Here, we review recent biotechnological approaches to biofortifying plants with vitamins, minerals, and other metabolites, and summarise synthetic biology advances that offer the opportunity to build on these early biofortification efforts.

Mabagala FS, Zhang T, Zeng X, He C, Shan H, Qiu C, Gao X, Zhang N, Su S. A review of amendments for simultaneously reducing Cd and As availability in paddy soils and rice grain based on meta-analysis. JOURNAL OF ENVIRONMENTAL MANAGEMENT 2024; 366:121661. [PMID: 38991353 DOI: 10.1016/j.jenvman.2024.121661] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/16/2024] [Revised: 06/17/2024] [Accepted: 06/29/2024] [Indexed: 07/13/2024]
Abstract
Arsenic (As) and cadmium (Cd) accumulation in rice grains is a global food safety issue, and various methods and materials have been used to remove or reduce As and Cd in agricultural soils and rice grains. Despite the availability of synthesized materials capable of simultaneous As and Cd reduction from soil and rice grains, the contributions, efficiency, and main ingredients of the materials for As and Cd immobilization remain unclear. The present study first summarized the biogeochemistry of As and Cd in paddy soils and their transfer in the soil-food-human continuum. We also reviewed a series of reported inorganic and organic materials for simultaneous immobilization of As and Cd in paddy soils, and their reduction efficiency of As and Cd bioavailability were listed and compared. Based on the abovementioned materials, the study conducted a meta-analysis of 38 articles with 2565 observations to quantify the impacts of materials on simultaneous As and Cd reduction from soil and rice grains. Meta-analysis results showed that combining organic and inorganic amendments corresponded to effect sizes of -62.3% and -67.8% on As and Cd accumulation in rice grains, while the effect sizes on As and Cd reduction in paddy soils were -44.2% and -46.2%, respectively. Application of Fe based materials significantly (P < 0.05) reduced As (-54.2%) and Cd (-74.9%), accounting for the highest immobilization efficiency of As and Cd in rice grain among all the reviewed materials, outweighing S, Mn, P, Si, and Ca based materials. Moreover, precipitation, surface complexation, ion exchange, and electrostatic attraction mechanisms were involved in the co-immobilization tactics. The present study underlines the application of combined organic and inorganic amendments in simultaneous As and Cd immobilization. It also highlighted that employing Fe-incorporated biochar material may be a potential strategy for co-mitigating As and Cd pollution in paddy soils and accumulation in rice grains.

JOURNAL OF HAZARDOUS MATERIALS 2024; 468:133851. [PMID: 38394901 DOI: 10.1016/j.jhazmat.2024.133851] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/26/2023] [Revised: 02/12/2024] [Accepted: 02/19/2024] [Indexed: 02/25/2024]
Abstract
As the most famous and widely used traditional Chinese medicine (TCM), Ligusticum sinense cv. Chuanxiong (L. Chuaniong) has been affected by cadmium (Cd) exceeding with high ability of Cd accumulation. There is relatively little research on Cd absorption and storage process in L. Chuanxiong, which is an important reason for the poor remediation efficiency. Hence, this study takes L. Chuanxiong as the point of penetration to explore how L. Chuanxiong affects rhizobacteria through root exudates to alter soil Cd intake, as well as to explore the migration and storage of Cd in its body with 0.10 (T0), 5.00 (T5), 10.00 (T10) mg/kg Cd contaminations. The results showed that the relative abundance of amino acids and phospholipids secreted from L. Chuanxiong root noticeably increased with increasing Cd levels, which directly activated soil Cd or extremely significantly (P < 0.01) recruited bacteria such as Bacillus, Arthrobacter to indirectly increase Cd availability. Under the interaction of root exudates and rhizobacteria, Cd bioavailability increased by 80.00% in rhizosphere soil and Cd accumulation in L. Chuanxiong increased 5.44-6.65 mg/kg. Cd subcellular distribution analysis demonstrated that Cd was mainly stored in the root (10-fold more than in the leaf), whose Cd content was cytoderm>cytoplasm>organelle in tissues. The sequential extraction results found that non-soluble phosphate and protein-chelated Cd dominated (85.00-90.00%) in the cell, while Cd cheated with alcohol soluble protein, amino acid salts, water-soluble organic acid in cell was minimal (5.50%). The phenomenon indicated that L. Chuanxiong fixed Cd in root (the medical part) with low translocation ability. This study can provide theoretical support for the high-quality production of L. Chuanxiong and other root medical plant in heavy metal influenced sites.

Environ Health Prev Med 2024; 29:41. [PMID: 39111872 PMCID: PMC11310560 DOI: 10.1265/ehpm.24-00095] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2024] [Accepted: 07/06/2024] [Indexed: 08/11/2024] Open
Abstract
BACKGROUND Arsenic is a toxic metalloid that can cause acute and chronic adverse health problems. Unfortunately, rice, the primary staple food for more than half of the world's population, is generally regarded as a typical arsenic-accumulating crop plant. Evidence indicates that arsenic stress can influence the growth and development of the rice plant, and lead to high concentrations of arsenic in rice grain. But the underlying mechanisms remain unclear. METHODS In the present research, the possible molecules and pathways involved in rice roots in response to arsenic stress were explored using bioinformatics methods. Datasets that involving arsenic-treated rice root and the "study type" that was restricted to "Expression profiling by array" were selected and downloaded from Gene Expression Omnibus (GEO) database. Differentially expressed genes (DEGs) between the arsenic-treated group and the control group were obtained using the online web tool GEO2R. Gene Ontology (GO) function and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed to investigate the functions of DEGs. The protein-protein interactions (PPI) network and the molecular complex detection algorithm (MCODE) of DEGs were analyzed using STRING and Cystoscope, respectively. Important nodes and hub genes in the PPI network were predicted and explored using the Cytoscape-cytoHubba plug-in. RESULTS Two datasets, GSE25206 and GSE71492, were downloaded from Gene Expression Omnibus (GEO) database. Eighty common DEGs from the two datasets, including sixty-three up-regulated and seventeen down-regulated genes, were then selected. After functional enrichment analysis, these common DEGs were enriched mainly in 10 GO items, including glutathione transferase activity, glutathione metabolic process, toxin catabolic process, and 7 KEGG pathways related to metabolism. After PPI network and MCODE analysis, 49 nodes from the DEGs PPI network were identified, filtering two significant modules. Next, the Cytoscape-cytoHubba plug-in was used to predict important nodes and hub genes. Finally, five genes [Os01g0644000, PRDX6 (Os07g0638400), PRX112 (Os07g0677300), ENO1(Os06g0136600), LOGL9 (Os09g0547500)] were verified and could serve as the best candidates associated with rice root in response to arsenic stress. CONCLUSIONS In summary, we elucidated the potential pathways and genes in rice root in response to arsenic stress through a comprehensive bioinformatics analysis.
