| 1 | Nitric oxide alleviates aluminum-induced oxidative damage through regulating the ascorbateglutathione cycle in roots of wheat显示文摘The possible association with nitric oxide(NO) and ascorbate-glutathione(As A-GSH) cycle in regulating aluminum(Al) tolerance of wheat(Triticum aestivum L.) was investigated using two genotypes with different Al resistance. Exposure to Al inhibited root elongation, and triggered lipid peroxidation and oxidation of As A to dehydroascorbate and GSH to glutathione disulfide in wheat roots. Exogenous NO significantly increased endogenous NO levels, and subsequently alleviated Al-induced inhibition of root elongation and oxidation of As A and GSH to maintain the redox molecules in the reduced form in both wheat genotypes. Under Al stress, significantly increased activities and gene transcriptional levels of ascorbate peroxidase, glutathione reductase, and dehydroascorbate reductase,were observed in the root tips of the Al-tolerant genotype Jian-864. Nitric oxide application enhanced the activity and gene transcriptional level of these enzymes in both wheat genotypes. g-Glutamylcysteine synthetase was not significantly Researaffected by Al or NO, but NO treatments increased the activity of glutathione peroxidase and glutathione S-transferase to a greater extent than the Al-treated wheat seedlings. Proline was significantly decreased by Al, while it was not affected by NO.These results clearly suggest that NO protects wheat root against Al-induced oxidative stress, possibly through its regulation of the As A-GSH cycle. | Chengliang Sun Lijuan Liu Yan Yu Wenjing Liu Lingli Lu Chongwei Jin Xianyong Lin | 2015 | Journal of Integrative Plant Biology2015,57,6: | 10 |
| 2 | Effect of nitrogen limitation on antioxidant qualities is highly associated with genotypes of lettuce(Lactuca sativa L.)显示文摘Antioxidants are highly beneficial to human health, and their accumulation in lettuce, one of the most popular leafy vegetables, depends on both genetic and environmental factors. Nitrogen(N) availability plays an essential role in regulating antioxidant accumulation, but the influence of genotype × N interactions on the antioxidant qualities of lettuce is poorly understood. Therefore, the present study investigated the variation of growth and antioxidant qualities of 20 lettuce(Lactuca sativa L.) genotypes(10 green lettuce genotypes and 10 red lettuce genotypes) under limited N(low N, LN) conditions and standard N(high N, HN) conditions. For all 20 genotypes, LN conditions reduced shoot(i.e., leaf) growth, but increased plant concentrations of vitamin C,glutathione, and phenolic compounds, with the exception of carotenoids, compared with HN conditions. Because of reduced biomass under LN conditions, not all lettuce genotypes exhibited increased antioxidant yields or total antioxidant capacity yield. The variation in antioxidant quality was primarily genetically determined. Generally, the green lettuce genotypes exhibited more pronounced increases in antioxidant yields and total antioxidant capacity yield than the red lettuce genotypes under LN conditions. These results suggest that even though LN conditions generally tend to improve the antioxidant qualities of lettuce, the extent of this effect is highly dependent on genotype. Therefore, genotype should be given priority in future studies that aim to improve antioxidant qualities in lettuce through N management. | Weiwei ZHOU Ting LV Yan HU Wenjing LIU Qingfang BI Chongwei JIN Lingli LU Xianyong LIN | 2020 | Pedosphere2020,30,3: | 4 |
| 3 | Molecular functions of nitric oxide and its potential applications in horticultural crops显示文摘Nitric oxide(NO)regulates plant growth,enhances nutrient uptake,and activates disease and stress tolerance mechanisms in most plants,making NO a potential tool for use in improving the yield and quality of horticultural crop species.Although the use of NO in horticulture is still in its infancy,research on NO in model plant species has provided an abundance of valuable information on horticultural crop species.Emerging evidence implies that the bioactivity of NO can occur through many potential mechanisms but occurs mainly through S-nitrosation,the covalent and reversible attachment of NO to cysteine thiol.In this context,NO signaling specifically affects crop development,immunity,and environmental interactions.Moreover,NO can act as a fumigant against a wide range of postharvest diseases and pests.However,for effective use of NO in horticulture,both understanding and exploring the biological significance and potential mechanisms of NO in horticultural crop species are critical.This review provides a picture of our current understanding of how NO is synthesized and transduced in plants,and particular attention is given to the significance of NO in breaking seed dormancy,balancing root growth and development,enhancing nutrient acquisition,mediating stress responses,and guaranteeing food safety for horticultural production. | Chengliang Sun Yuxue Zhang Lijuan Liu Xiaoxia Liu Baohai Li Chongwei Jin Xianyong Lin | 2021 | Horticulture Research2021,8,1: | 2 |
| 4 | Effect of Soil Drying Intensity During an Experimental Drying-Rewetting Event on Nutrient Transformation and Microbial Community Composition显示文摘Soil drying-rewetting(DRW) events affect nutrient transformation and microbial community composition; however, little is known about the influence of drying intensity during the DRW events. Therefore, we analyzed soil nutrient composition and microbial communities with exposure to various drying intensities during an experimental drying-rewetting event, using a silt loam from a grassland of northern China, where the semi-arid climate exposes soils to a wide range of moisture conditions, and grasslands account for over 40% of the nation's land area. We also conducted a sterilization experiment to examine the contribution of soil microbes to nutrient pulses. Soil drying-rewetting decreased carbon(C) mineralization by 9%–27%. Both monosaccharide and mineral nitrogen(N) contents increased with higher drying intensities(drying to ≤ 10% gravimetric water content), with the increases being 204% and 110% with the highest drying intensity(drying to 2% gravimetric water content), respectively, whereas labile phosphorus(P)only increased(by 105%) with the highest drying intensity. Moreover, levels of microbial biomass C and N and dissolved organic N decreased with increasing drying intensity and were correlated with increases in dissolved organic C and mineral N, respectively,whereas the increases in labile P were not consistent with reductions in microbial biomass P. The sterilization experiment results indicated that microbes were primarily responsible for the C and N pulses, whereas non-microbial factors were the main contributors to the labile P pulses. Phospholipid fatty acid analysis indicated that soil microbes were highly resistant to drying-rewetting events and that drought-resistant groups were probably responsible for nutrient transformation. Therefore, the present study demonstrated that moderate soil drying during drying-rewetting events could improve the mineralization of N, but not P, and that different mechanisms were responsible for the C, N, and P pulses observed during drying-rewetting events. | SUN Dashend BI Qingfang LI Kejie ZHU Jun ZHANG Qichun JIN Chongwei LU Lingli LIN Xianyong | 2018 | Pedosphere2018,28,4: | 2 |

| 8 | Altered expression profile of long non-coding RNAs during heart aging in mice显示文摘Objective:Long noncoding RNAs(lncRNAs)play an important role in regulating the occurrence and development of cardiovascular diseases.However,the role of lncRNAs in heart aging remains poorly understood.The objective of this study was to identify differentially expressed lncRNAs in the heart of aging mice and elucidate the relevant regulatory pathways of cardiac aging.Materials and methods:Echocardiography was used to detect the cardiac function of 18-months(aged)and 3-months(young)old C57BL/6 mice.Microarray analysis was performed to unravel the expression profiles of lncRNAs and mRNAs,and qRT-PCR to verify the highly dysregulated lncRNAs.Results:Our results demonstrated that the heart function in aged mice was impaired relative to young ones.Microarray results showed that 155 lncRNAs were upregulated and 37 were downregulated,and 170 mRNAs were significantly upregulated and 44 were remarkably downregulated in aging hearts.Gene ontology analysis indicated that differentially expressed genes are mainly related to immune function,cell proliferation,copper ion response,and cellular cation homeostasis.KEGG pathway analysis showed that the differentially expressed mRNAs are related to cytokine-cytokine receptor interaction,inflammatory mediator regulation of TRP channels,and the NF-kappa B signaling pathway.Conclusion:These results imply that the differentially expressed lncRNAs may regulate the development of heart aging.This study provides a new perspective on the potential effects and mechanisms of lncRNAs in heart aging. | Xiuxiu Wang Bingjie Hua Meixi Yu Shenzhen Liu Wenya Ma Fengzhi Ding Qi Huang Lai Zhang Chongwei Bi Ye Yuan Mengyu Jin Tianyi Liu Ying Yu Benzhi Cai Baofeng Yang | 2022 | Frigid Zone Medicine2022,2,2: | 0 |
