Interaction Between Ustilaginoidea virens and Rice and Its Sustainable Control

Rice Science (2023)

Zhang Feng-min Zhenzhen Cao Xin Zheng Yuntao He Mingxue Chen

Ustilaginoidea virens is a common rice pathogen that can easily lead to a decline in rice quality and the production of toxins, posing potential risks to human health. In this review, we conduct a comprehensive literature review of research since the discovery of rice false smut. We provide a comprehensive and, at times, critical overview of the main results and findings from related research, and propose future research directions. Firstly, we delve into the interaction between U. virens and rice, including the regulation of transcription factors, the process of U. virens infecting rice panicles, and the plant immune response caused by rice infection. Following that, we discuss the identification and characterization of mycotoxins produced by the pathogenic fungus, as well as and strategies for disease management. We emphasize the importance of comprehensive agricultural prevention and control methods for the sustainable management of U. virens. This knowledge will update our understanding of the interaction between U. virens and rice plants, offering a valuable perspective for those interested in U. virens.

Effects of interaction between manganese and cadmium on plant growth and contents of cadmium and manganese in rice.

Zhongguo shuidao kexue (2010)

Qin Du Mingxue Chen Rong Zhou Zhaoyun Cao Zhiwei Zhu

The effects of Mn treatment on rice growth,and Cd,Mn,Fe and Zn contents and their distribution in shoots and roots under Cd stress were investigated under hydroponics.The results showed that Cd toxicity to rice plants was markedly alleviated at normal Mn level (about 0.50 mg/L) with higher plant height,root length,and contents of chlorophyll a and chlorophyll b than at low Mn level.With the rising Cd concentration in culture solution,the Cd contents in shoots and roots increased.Under the same Cd level,the Cd content increased in rice shoots,while decreased in rice roots with the increase of Mn concentration in culture solution.The contents of Fe and Zn in rice plants significantly decreased under high level treatments of Mn and Cd.Moreover,Cd accumulation mechanism in rice plants and the application value of Mn fertilizer in alleviating Cd stress were also discussed.

Association Study Reveals Genetic Loci Responsible for Arsenic, Cadmium and Lead Accumulation in Rice Grain in Contaminated Farmlands

Frontiers in Plant Science (2019)

Xiu‐Yan Liu Sunlu Chen Mingxue Chen Guangyong Zheng Yu Peng

Accumulation of toxic heavy metals and metalloids (THMMs) in crop grain remarkably affects food safety and human health. Reducing the content of THMMs in grain requires the identification and manipulation of the genes regulating their accumulation. This study aimed to determine the genetic variations affecting grain THMM accumulation in rice by using association mapping. We used 276 accessions with 416 K single nucleotide polymorphisms (SNPs) and performed genome-wide association analysis of grain THMM concentrations in rice grown in heavily multi-contaminated farmlands. We detected 22, 17, and 21 quantitative trait loci (QTLs) for grain arsenic, cadmium, and lead concentrations, respectively. Both inter- and intra-subpopulation variants accounted for these QTLs. Most QTLs contained no known THMM-related genes and represented unidentified novel genes. We examined the candidate genes in qGAS1, a QTL for grain arsenic concentration with the best P-value detected for the entire population. We speculated that a transport protein of the multidrug and toxin extrusion family could be the candidate gene for this QTL. Our study suggested that the genetic regulation of grain THMM accumulation is very complex and largely unknown. The QTLs and SNPs identified in this study might help in the identification of new genes regulating THMM accumulation and aid in marker-assisted breeding of rice with low grain THMM content.

Determination of 80 Pesticide Residues in Vegetables and Fruits by Liquid Chromatography-Tandem Mass Spectrometry

Journal of Instrumental Analysis (2010)

Mingxue Chen

A liquid chromatography-tandem mass spectrometric(LC-MS/MS)method was developed for the simultaneous determination of 80 pesticides of different chemical classes(mainly including organophosphorous compounds,acetanilide herbicide and carbamates)in vegetables and fruits.The sample was extracted with acetonitrile,and cleaned up by PSA and C18 columns.80 pesticides were separated on a C18 column(1.8 μm,100 mm×2.1 mm i.d.)using 0.1% formic acid and 5 mmol/L ammonium acetate in water(A)-acetonitrile(B)as mobile phase in gradient elution.The analytes were detected with positive-ion electrospray ionization-mass spectrometry in dynamic multiple reaction monitoring(Dynamic MRM)mode.Under the optimal conditions,the linear ranges for all the pesticides were over 3 orders of magnitude with correlation coefficients not less than 0.99.The detection limits(LODs)ranged from 0.02 to 3 μg/kg(S/N=3).The recoveries of 80 pesticides were measured from samples of different fruits and vegetables.The results showed that the mean recoveries of 80 pesticide residues at two spiked concentration levels of 0.01 and 0.05 mg/kg were in the range of 64%-118% and 72%-108%,respectively,with relative standard deviations(RSDs)of 3.7%-29.1% and 3.4%-27.9%,respectively.The method was rapid,sensitive,reliable,and could be used to analyse the pesticide residues in a wide variety of fruits and vegetables.

Assessing the ecological impact and microbial restoration of quinclorac-contaminated paddy fields through high-throughput sequencing technology

Environmental Technology & Innovation (2023)

Siqi Huang Zhenzhen Cao Meiyan Guan Mingxue Chen Xiaoyan Lin

Quinclorac (QNC) is a highly selective herbicide with hormone-like properties and low toxicity, primarily employed to control barnyard grass in paddy fields. Owing to its extended half-life, it readily accumulates in soil, thereby inhibiting the growth and development of subsequent crops. Additionally, long-term residual accumulation of QNC has notable repercussions on soil microbial communities. Certain bacteria capable of degrading QNC have been identified, effectively diminishing its soil residues and thus mitigating its ecological impact. For the first time, high-throughput sequencing technology (Illumina MiSeq) was employed to assess the influence of both QNC and the newly isolated QNC-degrading bacterial strain D on soil microorganisms in contaminated paddy fields. The study yielded significant findings: substantial variances were observed in the composition and structural diversity of microbial communities across various treatments. Furthermore, strain D demonstrated a restorative effect on microbial community composition and structural diversity. QNC was found to suppress specific functions within soil bacteria and fungi, altering the constitution of functional groups. Interestingly, strain D counteracted the suppressive effect of QNC, contributing positively to the restoration of soil microbial ecology. Consequently, this research offers a novel strain resource and a theoretical foundation for microbiologically mitigating QNC contamination in paddy fields.

Surgical Therapy and Tissue Engineering for Meniscal Repair

Tissue Engineering Part B Reviews (2024)

Hao Wang Jie Wu L. Yang Shuyun Liu Xiang Sui

Meniscal damage is one of the prevalent causes of knee pain, swelling, instability, and functional compromise, frequently culminating in osteoarthritis (OA). Timely and appropriate interventions are crucial to relieve symptoms and prevent or delay the onset of OA. Contemporary surgical treatments include total or partial meniscectomy, meniscal repair, allograft meniscal transplantation, and synthetic meniscal implants, but each presents its specific limitations. Recently, regenerative medicine and tissue engineering have emerged as promising fields, offering innovative prospects for meniscal regeneration and repair. This review delineates current surgical methods, elucidating their specific indications, advantages, and disadvantages. Concurrently, it delves into state-of-the-art tissue engineering techniques aimed at the functional regenerative repair of meniscus. Recommendations for future research and clinical practice are also provided.

Determination of five arsenic species in rice by liquid chromatography-inductively coupled plasma-mass spectrometry

Chinese Journal of Chromatography (2014)

Jiadi GONG Xiaolin Cao Zhaoyun Cao Yingfang Bian Shasha Yu

A method was developed for the simultaneous determination of arsenic acid [As (V)], arsenious acid [As (III)], arsenobetaine (AsB), monomethylarsonic acid (MMA) and dimethylarsinic acid (DMA) in rice by liquid chromatography-inductively coupled plasma-mass spectrometry (LC-ICP-MS). The extraction reagent was 0.3 mol/L nitric acid with heat-assistant condition for 1.5 h at 95 degrees C. Then, the five arsenic species were separated by an anion exchange column (Dionex IonPac AS19, 250 mm x 4 mm) and detected by ICP-MS. Four kinds of extracted solutions were compared through the extraction efficiency. The concentration of nitric acid, the temperature and the extraction time were optimized. The recoveries of the five arsenic species spiked in rice at two levels ranged from 89.6% to 99.5% with the relative standard deviations (RSDs, n = 5) of 0.6% - 3.6%. The measured values of the arsenic species in standard rice materials were consistent with their standard values. The linear ranges were 0.05 - 200 microg/L for AsB and DMA, 0.10-400 microg/L for As (III) and MMA, 0.15-600 microg/L for As (V). The limits of detection for the five arsenic species were 0.15-0.45 microg/kg. The results showed that the method is much more precise for the risk assessment of the rice. This method is simple, accurate and durable for the determination of arsenic species in rice.
