| 1 | Functional identification of lncRNAs in sweet cherry(Prunus avium)pollen tubes via transcriptome analysis using single-molecule long-read sequencing显示文摘Sweet cherry(Prunus avium)is a popular fruit with high nutritional value and excellent flavor.Although pollen plays an important role in the double fertilization and subsequent fruit production of this species,little is known about its pollen tube transcriptome.In this study,we identified 16,409 transcripts using single-molecule sequencing.After filtering 292 transposable elements,we conducted further analyses including mRNA classification,gene function prediction,alternative splicing(AS)analysis,and long noncoding RNA(lncRNA)identification to gain insight into the pollen transcriptome.The filtered transcripts could be matched with 3,438 coding region sequences from the sweet cherry genome.GO and KEGG analyses revealed complex biological processes during pollen tube elongation.A total of 2043 AS events were predicted,7 of which were identified in different organs,such as the leaf,pistil and pollen tube.Using BLASTnt and the Coding-Potential Assessment Tool(CPAT),we distinguished a total of 284 lncRNAs,among which 154 qualified as natural antisense transcripts(NATs).As the NATs could be the reverse complements of coding mRNA sequences,they might bind to coding sequences.Antisense transfection assays showed that the NATs could regulate the expression levels of their complementary sequences and even affect the growth conditions of pollen tubes.In summary,this research characterizes the transcripts of P.avium pollen and lays the foundation for elucidating the physiological and biochemical mechanisms underlying sexual reproduction in the male gametes of this species. | Yang Li Chuanbao Wu Chunsheng Liu Jie Yu Xuwei Duan Wenqi Fan Jing Wang Xiaoming Zhang Guohua Yan Tianzhong Li Kaichun Zhang | 2019 | Horticulture Research2019，6，1： | 1 |
| 2 | C-doped BiOCl/Bi_(2)S_(3) heterojunction for highly efficient photoelectrochemical detection and photocatalytic reduction of Cr(VI)显示文摘Novel C-BiOCl/Bi_(2)S_(3) composites are prepared by hydrothermal C doping in BiOCl and in-situ growth of Bi2 S3 on C-BiOCl.Compared with BiOCl,C-BiOCl has a larger exposed surface area and can effectively absorb visible light.The construction of a heterojunction in C-BiOCl/Bi_(2)S_(3) further promotes the separation and transfer of photogenerated carriers.With improved photoelectric properties,the optimized 5C-BiOCl/5Bi_(2)S_(3) is applied as a dual-functional composite for photoelectrochemical(PEC)detection and photocatalytic(PC)reduction of Cr(VI).The 5C-BiOCl/5Bi_(2)S_(3) shows a linear range of 0.02-80μM for PEC cathodic detection of Cr(VI)with a detection limit of 0.01628μM.Additionally,99.5%of Cr(VI)can be removed via absorption and PC reduction by 5C-BiOCl/5Bi_(2)S_(3),with the reduction rate constant(k)336 times higher than that of BiOCl. | Chunli Wang Nazhen Liu Xia Zhao Yong Tian Xuwei Chen Yanfeng Zhang Liang Fan Baorong Hou | 2023 | Journal of Materials Science & Technology2023，，33： | 0 |
| 3 | Fe-doped Co_(3)O_(4) nanowire strutted 3D pinewood-derived carbon: A highly selective electrocatalyst for ammonia production via nitrate reduction显示文摘Nitrate(NO_(3)^(-)),a nitrogen-containing pollutant,is prevalent in aqueous solutions,contributing to a range of environmental and health-related issues.The electrocatalytic reduction of NO_(3)^(-)holds promise as a sustainable approach to both eliminating NO_(3)^(-)and generating valuable ammonia(NH_(3)).Nevertheless,the reduction reaction of NO_(3)^(-)(NO_(3)^(-)RR),involving 8-electron transfer process,is intricate,necessitating highly efficient electrocatalysts to facilitate the conversion of NO_(3)^(-)to NH_(3).In this study,Fe-doped Co_(3)O_(4) nanowire strutted three-dimensional(3D)pinewood-derived carbon(Fe-Co_(3)O_(4)/PC)is proposed as a high-efficiency NO_(3)^(-)RR electrocatalyst for NH_(3) production.Operating within 0.1 M NaOH containing NO_(3)^(-),Fe-Co_(3)O_(4)/PC demonstrates exceptional performance,obtain an impressively large NH_(3) yield of 0.55 mmol·h^(-1)·cm^(-2) and an exceptionally high Faradaic efficiency of 96.5%at-0.5 V,superior to its Co_(3)O_(4)/PC counterpart(0.2 mmol·h^(-1)·cm^(-2),73.3%).Furthermore,the study delves into the reaction mechanism of Fe-Co_(3)O_(4) for NO_(3)^(-)RR through theoretical calculations. | Xuwei Liu Chaozhen Liu Xun He Zhengwei Cai Kai Dong Jun Li Xiaoya Fan Ting Xie Xiya Yang Yonglan Luo Dongdong Zheng Shengjun Sun Sulaiman Alfaifi Feng Gong Xuping Sun | 2024 | Nano Research2024，17，4： | 0 |
| 4 | Multi-Hop Transmission Method of 5G Millimeter Wave Relay Based on Network Coding显示文摘With the rapid development of the Internet technology,millimeter wave(mmWave)will be used as a supplement to 5G low frequency bands to meet the extremely high system capacity requirements of 5G in hot spots.Although 5G mmWave communication can adapt to the needs of 5G network and carry a large amount of transmitted data,transmission stability has become one of the key technical issues of 5G network mmWave communication due to problems such as strong attenuation and poor penetration of mmWave.In order to improve the efficiency of the mmWave multi-hop transmission,we propose a 5G mmWave multi-hop transmission method based on network coding,which can adapt to the current wireless network environment,improve spectrum efficiency and increase network throughput.Based on MATLAB simulation experiments,it is verified that the proposed method can greatly improve the transmission efficiency and reduce the signal loss under the premise of ensuring the accurate signal transmission. | Yilin Wang Weisheng He Xuwei Fan Lianfen Huang Jie Yang Yuliang Tang | 2022 | China Communications2022，19，12： | 0 |
