| 1 | Arrangement models of alkylammonium cations in the interlayer of HDTMA^+pillared montmorillonites显示文摘The orientation of HDTMA+ in the interlayer of organic pillared montmorillonites prepared at different concentrations of HDTMA+ have been studied using X-ray powder diffraction (XRD) and theoretical calculation. A series of arrangement models of HDTMA+ in the interlayer of montmorillonite have been proposed as lateral-monolayer (LM), lateral-bilayer (LB), pseudotrilayer (PT), paraf-fin-type-monolayer (PM), paraffin-type-bilayer (PB). With the increase of the concentration of HDTMA+, the arrange-ment model of HDTMA+ in the interlayer of montmorillo-nites changes as lateral-monolayer→lateral-bilayer→para- ffin-type monolayer→pseudotrilayer→paraffin-type-bilayer and the packing density of HDTMA+ in the interlayer in-creases gradually. In the intermediate stages, different mod-els may coexist. | ZHU Jianxi, HE Hongping, GUO Jiugao, YANG Dan & XIE Xiande Guangzhou Institute of Geochemistry, Chinese Academy of Sciences, Guangzhou 510640, China Correspondence should be addressed to He Hongping | 2003 | Chinese Science Bulletin2003，48，4： | 16 |
| 2 | Systematic Characterization of Long Non-Coding RNAs and Their Responses to Drought Stress in Dongxiang Wild Rice显示文摘Long non-coding RNAs(lncRNAs) play important roles in response to various biotic and abiotic stresses. So far, systematic identification and characterization of lncRNAs have been reported in a few model plant species and major crops, but their roles in abiotic stress response have not yet been reported in common wild rice(Oryza rufipogon). Dongxiang wild rice(DXWR) possesses a high degree of drought resistance and has been well recognized as a precious genetic resource for drought resistant rice breeding. We presented the reference catalog of 1 655 novel lncRNA transcripts in DXWR using strand-specific RNA sequencing and bioinformatics approaches. Meanwhile, a total of 1092 lncRNAs were determined as differentially expressed lncRNAs under drought stress. Quantitative real-time PCR results exhibited a high concordance with RNA sequencing data, which confirmed that the expression patterns of lncRNAs based on RNA sequencing were highly reliable. Furthermore, 8 711 transcripts were predicted as target genes of the differentially expressed lncRNAs. Functional annotation analysis based on Gene Ontology and Kyoto Encyclopedia of Genes and Genomes databases showed that the target genes were significantly enriched in cellular and metabolic processes, cell part, binding and plant hormone signal transduction, as well as many other terms related to abiotic stress resistance. These results expanded our understanding of lncRNA biology and provided candidate regulators for genetic improvement of drought resistance in rice cultivars. | QI Weidong CHEN Hongping YANG Zuozhen HU Biaolin LUO Xiangdong AI Bing LUO Yuan HUANG Yu XIE Jiankun ZHANG Fantao | 2020 | Rice science2020，27，1： | 3 |
| 3 | Identification and Characterization of Drought Stress-Responsive Novel microRNAs in Dongxiang Wild Rice显示文摘MicroRNAs(miRNAs) are non-coding small RNAs, which play important regulatory roles in response to biotic and abiotic stresses. Dongxiang wild rice(Oryza rufipogon, DXWR) can survive in extreme drought environment, but its molecular mechanism of drought resistance is still largely unknown. To further explore miRNA regulatory mechanisms involved in drought resistance, we identified 138 novel miRNAs in DXWR using small RNA sequencing and bioinformatics approaches, and found that the expression levels of 67 novel miRNAs were significantly affected by drought stress. In total, 200 candidate target genes were predicted and annotated for the drought stress-responsive novel miRNAs. Gene Ontology(GO) analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathways suggested that most of the target genes were related to metabolism. Stem-loop quantitative real-time PCR(qRT-PCR) results exhibited high concordance with sequencing data, which confirmed that miRNA expression patterns based on small RNA sequencing in the present study were reliable. Meanwhile, qRT-PCR validated the inverse expression patterns between several miRNAs and their target genes. These results will enhance our understanding of miRNA regulatory mechanisms in response to drought stress in DXWR, and can serve as an important reference for the protection and utilization of this valuable genetic resource. | ZHANG Fantao LUO Yuan ZHANG Meng ZHOU Yi CHEN Hongping HU Biaolin XIE Jiankun | 2018 | Rice science2018，25，4： | 3 |

| 7 | Discovery of spirooxindole-ferrocene hybrids as novel MDM2 inhibitors显示文摘A series of spirooxindole-ferrocene hybrids bearing five or four contiguous chiral centers were designed and synthesized via organocatalysis.In vitro protein binding and cellular proliferation assays suggested that compound 5 d was the most potent mouse double minute 2 homolog(MDM2)inhibitor.In addition,mechanistic studies indicated that compound 5 d suppressed MDM2-mediated p53 degradation,induced apoptosis and promoted oxidative damage.Molecular docking studies have suggested that 5 d binds to MDM2 by mimicking the Trp23 and Leu26 residues of p53.This work can provide a basis for the development of novel multifunctional MDM2 inhibitors.The further exploration of more derivatives from this library and additional investigation of organocatalysis application in the development of new molecules may generate new potential lead compounds for cancer-targeted therapy. | Jun Mu Xin Xie Shanshan Xiong Yuehua Zhang Yuting Wang Qian Zhao Hongping Zhu Wei Huang Gu He | 2021 | Chinese Chemical Letters2021，32，6： | 1 |
| 8 | Co-feeding with DME:An effective way to enhance gasoline production via low temperature aromatization of LPG显示文摘The aromatization of light alkenes in liquefied petroleum gas (LPG) with and without dimethyl ether (DME) addition in the feed was investigated on a modified ZSM-5 catalyst.The results showed that under the given reaction conditions the selectivity of alkenes to high-octane gasoline blending components was markedly enhanced and the formation of propane and butanes was greatly suppressed with the addition of DME.It was also found that the distribution of C5+ components was changed a lot with DME addition into the LPG feed.The formation of branched hydrocarbons (mainly C6 C8 i-paraffin) and multi-methyl substituted aromatics,which are high octane number gasoline blending components,was promoted significantly,while the content of n-paraffins and olefins in C5+ components was decreased obviously,indicating that in addition to the oligomerization,cracking,hydrogen-transfer and dehydrogenation-cyclization of alkenes,the methylation of the formed aromatics and olefins intermediates also plays an important role in determining the product distribution due to the high reactivity of surface methoxy groups formed by DME.And this process,in combination with the syngas-to-methanol/DME technology,provides an alternative way to the production of high-octane gasoline from coal,natural gas or renewable raw materials. | Xiangxue Zhu Yuzhong Wang Xiujie Li Hongbing Li Peng Zeng Jie An Fucun Chen Sujuan Xie Hongping Lan Dawei Wang Shenglin Liu Longya Xu | 2013 | Journal of Energy Chemistry2013，22，5： | 1 |

| 10 | Spin switching in corrole radical complex显示文摘Spintronics is a cutting-edge field of developing new electronic devices by manipulating the electron spin and magnetic moment[1].Traditional spintronic research mainly focuses on transition metals and inorganic semiconductors,while organic molecules have the advantage of being extremely easy to realize efficient spin control by modifying the specific external conditions for desired electronic structures and magnetic characteristics.Corrole,as a ring-contracted porphyrin,is the aromatic analog of the central macrocycle of vitamin Bi2.Corrole has a squeezed inner cavity and three inner NHs in its free-base form,making it easier to stabilize high-valent metal ions and thus a promising candidate in spintronics. | Chunyan Yu Hongping Xiao Hua Lu Yongshu Xie | 2024 | Chinese Chemical Letters2024，35，1： | 0 |
