| 1 | Sdr4 dominates pre-harvest sprouting and facilitates adaptation to local climatic condition in Asian cultivated rice显示文摘Pre-harvest sprouting(PHS),which reduces grain yield and quality,is controlled by seed dormancy genes.Because few dormancy-related genes have been cloned,the genetic basis of seed dormancy in rice(Oryza sativa L.)remains unclear.Here,we performed a genome-wide association study and linkage mapping to dissect the genetic basis of seed dormancy in rice.Our findings suggest that Seed Dormancy4(Sdr4),a central modulator of seed dormancy,integrates the abscisic acid and gibberellic acid signaling pathways at the transcriptional level.Haplotype analysis revealed that three Sdr4 alleles in rice cultivars already existed in ancestral Oryza rufipogon accessions.Furthermore,like the semi-dwarf 1(SD1)and Rc loci,Sdr4 underwent selection during the domestication and improvement of Asian cultivated rice.The distribution frequency of the Sdr4-n allele in different locations in Asia is negatively associated with local annual temperature and precipitation.Finally,we developed functional molecular markers for Sdr4,SD1,and Rc for use in molecular breeding.Our results provide clues about the molecular basis of Sdr4-regulated seed dormancy.Moreover,these findings provide guidance for utilizing the favorable alleles of Sdr4 and Rc to synergistically boost PHS resistance,yield,and quality in modern rice varieties. | Bo Zhao Hui Zhang Tianxiao Chen Ling Ding Liying Zhang Xiali Ding Jun Zhang Qian Qian Yong Xiang | 2022 | Journal of Integrative Plant Biology2022，64，6： | 3 |

| 5 | Relationship between NO_2 Concentration and Meteorological Factors in the Urban Area of Wanzhou District显示文摘Firstly,the daily variations of NO2 concentration in the urban area of Wanzhou in 2012 were analyzed,and then the relationship between NO2 concentration and meteorological factors( precipitation,atmospheric pressure,wind speed,temperature,relative humidity and sunshine hours) was discussed. Finally,the multiple linear regression equation was established to predict NO2 concentration. The results showed that NO2 concentration in the urban area of Wanzhou did not exceed 80 μg /m3in most days from January 1 to December 31 in 2012. Among the six meteorological factors,NO2 concentration correlated significantly with three meteorological factors,that is,NO2 concentration correlated negatively with atmospheric pressure and wind speed but positively with relative humidity. NO2 concentration in the urban area of Wanzhou could be predicted using the multiple linear regression model. According to the rose diagram of wind directions,the wind blowing from the NNW was dominant in the urban area of Wanzhou. | Xiang Yingchun Zhang Liying Mao Xiaozhen Ma Huiyan Qian Ruozhi | 2014 | Meteorological and Environmental Research2014，5，3： | 1 |

| 7 | A review on electronically conducting polymers for lithium-sulfur battery and lithium-selenium battery:Progress and prospects显示文摘Lithium-sulfur(Li-S) batteries and lithium-selenium(Li-Se) batteries,as environmental protection energy storage systems with outstanding theoretical specific capacities and high energy densities,have become the hotspots of current researches.Besides,elemental S(Se) raw materials are widely sourced and their production costs are both low,which make them considered one of the new generations of high energy density electrochemical energy storage systems with the most potential for development.However,poor conductivity of elemental S/Se and the notorious 'shuttle effect' of lithium polysulfides(polyselenides) severely hinder the commercialization of Li-S/Se batteries.Thanks to the excellent electrical conductivity and strong absorption of lithium polysulfide(polyselenide) about electronically conducting polymer,some of the above thorny problems have been effectively alleviated.The review presents the fundamental studies and current development trends of common electronically conducting polymers in various components of Li-S/Se batteries,which involves polyaniline(PANI) polypyrrole(PPy),and polythiophene(PTh) with its derivatives,e.g.polyethoxythiophene(PEDOT) and poly(3,4-ethylene dioxythiophene)-poly(styrenesulfonate)(PEDOT:PSS).Finally,the review not only summarizes the research directions and challenges facing the application of electronically conducting polymers,but also looks forward to the development prospects of them,which will provide a way for the practical use of electronically conducting polymers in Li-S/Se batteries with outstanding electrochemical properties in the short run. | Hengying Xiang Nanping Deng Huijuan Zhao Xiaoxiao Wang Liying Wei Meng Wang Bowen Cheng Weimin Kang | 2021 | Journal of Energy Chemistry2021，30，7： | 1 |

| 11 | The MKK3–MPK7 cascade phosphorylates ERF4 and promotes its rapid degradation to release seed dormancy in Arabidopsis显示文摘Seeds establish dormancy to delay germination until the arrival of a favorable growing season.In this study,we identify a fate switch comprised of the MKK3–MPK7 kinase cascade and the ethylene response factor ERF4 that is responsible for the seed state transition from dormancy to germination.We show that dormancy-breaking factors activate the MKK3–MPK7 module,which affects the expression of some a-EXPANSIN(EXPA)genes to control seed dormancy.Furthermore,we identify a direct downstream substrate of this module,ERF4,which suppresses the expression of these EXPAs by directly binding to the GCC boxes in their exon regions.The activated MKK3–MPK7 module phosphorylates ERF4,leading to its rapid degradation and thereby releasing its inhibitory effect on the expression of these EXPAs.Collectively,our work identifies a signaling chain consisting of protein phosphorylation,degradation,and gene transcription,by which the germination promoters within the embryo sense and are activated by germination signals from ambient conditions. | Xi Chen Qiujia Li Ling Ding Shengnan Zhang Siyao Shan Xiong Xiong Wenhui Jiang Bo Zhao Liying Zhang Ying Luo Yiming Lian Xiuqin Kong Xiali Ding Jun Zhang Chunli Li Wim J.J.Soppe Yong Xiang | 2023 | Molecular Plant2023，16，11： | 0 |
| 12 | Promoting New Pattern of Jiangxi Marine Electromechanical Industry Development显示文摘Shipbuilding industry is the traditional pillar industry of Jiangxi province. Under the background of the continuous downward trend of economic indicators for the national shipbuilding industry, especially the sharp decline in global demand for new ships, domestic orders for new ships and handheld ship orders have dropped at this stage compared with the same period last year, and under the background that the problems such as “financing difficulties” and “receiving order difficulties” in the shipbuilding industry have not been alleviated, in recent years, the shipbuilding industry enterprises in the province have taken measures such as actively responding, strengthening planning first, dislocation competition, lean management, diversified operation, and so on. | Zhang Liying Xiang Zhao | 2019 | 船舶经济贸易2019，，8： | 0 |
| 13 | Predicting the utilization factor of blasthole in rock roadways by random forest显示文摘The utilization factor of blasthole is a crucial indicator of the effectiveness of blasting in rock roadways.A significant value means that the explosive energy is fully utilized,the single-cycle advance is high,and the excavation rate is fast.A good blasting programme is a prerequisite for improving the utilization rate and predicting the utilization rate before blasting operations can verify the feasibility of the blasting programme.Firstly,a database of rock roadway blasting covering different geological and production conditions is estab-lished.Secondly,error analysis and the Gini coefficient method are used to weight the characteristic variables,quantify the importance of the variables and identify eight key indicators affecting the blasting hole utilization rate.Then,a random forest algorithm-based model for predicting utilization factor of blasthole is proposed,and the results of the model on the test set are:root mean square error(RMSE)is 0.0137,mean absolute error(MAE)is 0.0087,and coefficient of determination(R^(2))is 0.905.The performance of this method is com-pared with that of the neural network and support vector machine models on the test sets to verify the superiority of the random forest algorithm.Finally,to verify the generalization ability and practicality of the random forest prediction model,the model is applied to the rock roadway blasting construction of Gu Bei coal mine in Anhui Province.The results show that R2 is 0.913,so the model is reliable and accurate,which can meet the actual engineering requirements and lay the foundation for the promotion and application of this technology. | Xinmin Ma Zhenyu Chen Pan Chen Haozhang Zheng Xingyu Gao Junjie Xiang Liying Chen Yipei Huang | 2023 | Underground Space2023，，4： | 0 |
