| 1 | Verification and fine-mapping of QTLs conferring days to flowering in soybean using residual heterozygous lines显示文摘The results of QTL mapping based on a primary mapping population should be further verified and refined for its real utilization in marker-assisted selection or map-based cloning.The primary mapping population contains 114 BC1F1 plants of the backcross between Essex (maturity group V,MG V) as the donor parent and ZDD2315 (MG II) as the recurrent parent.In this study,a genetic linkage map with 250 SSR markers spanning a total length of 2963.5 cM on 25 linkage groups (LG) was constructed using software MAPMAKER3.0.Six kinds of genetic statistical models of 4 softwares,i.e.WinQTL Cartographer Version 2.5,IciMapping Version 2.0,MapQTL Version 5.0 and QTLnetwork Version 2.0,were used to map QTLs conferring days to flowering of the BC1F3 lines.Nine QTLs were mapped on 6 different linkage groups (LG).Of those,6 QTLs were detected by at least two different genetic statistical models,while the other three were detected by only one procedure.Among the three QTLs,Flwdt7 was mapped between Sat_213 and Satt643 on LG C2 with only 11.0% contribution rate.For confirmation of Flwdt7,5 RHL populations were developed through selfing eight BC1F5 plants heterozygous at seven markers around the locus.The RHL populations with the same segregating loci were bulked and used to construct a secondary linkage map of the specific segment using software JoinMap 3.0.The genetic distances among the markers on the specific segment became shorter than those of the whole genome map.On the secondary map,Flwdt7 was mapped between Satt277 and Satt489,next to its primary interval Sat_213-Satt643,with distance 1.40 cM to Satt277 and 0.45 cM to Satt489,confidence interval narrowed to 2.7 cM,and contribution rate increased to 36.8%.The results were confirmed with significance analysis among marker genotypes on individual loci and comparison analysis of target marker intervals among near isogenic lines (plants).Thus the strategy by using residual heterozygous lines for QTL fine-mapping on target segments based on primary whole genome scanning with multiple mapping models was demonstrated to be effective. | SU ChengFu LU WeiGuo ZHAO TuanJie GAI JunYi | 2010 | Chinese Science Bulletin2010，55，6： | 6 |
| 2 | Celastrol enhances transcription factor EB (TFEB)-mediated autophagy and mitigates Tau pathology:Implications for Alzheimer's disease therapy显示文摘Alzheimer's disease(AD),characterized by the accumulation of protein aggregates including phosphorylated Tau aggregates,is the most common neurodegenerative disorder with limited therapeutic agents.Autophagy plays a critical role in the degradation of phosphorylated Tau aggregates,and transcription factor EB(TFEB)is a master regulator of autophagy and lysosomal biogenesis.Thus,small-molecule autophagy enhancers targeting TFEB hold promise for AD therapy.Here,we found that celastrol,an active ingredient isolated from the root extracts of Tripterygium wilfordii(Lei Gong Teng in Chinese)enhanced TFEB-mediated autophagy and lysosomal biogenesis in vitro and in mouse brains.Importantly,celastrol reduced phosphorylated Tau aggregates and attenuated memory dysfunction and cognitive deficits in P301S Tau and 3xTg mice,two commonly used AD animal models.Mechanistical studies suggest that TFEB-mediated autophagy-lysosomal pathway is responsible for phosphorylated Tau degradation in response to celastrol.Overall,our findings indicate that Celastrol is a novel TFEB activator that promotes the degradation of phosphorylated Tau aggregates and improves memory in AD animal models.Therefore,Celastrol shows potential as a novel agent for the treatment and/or prevention of AD and other tauopathies. | Chuanbin Yang Chengfu Su Ashok Iyaswamy Senthil Kumar Krishnamoorthi Zhou Zhu Sichang Yang Benjamin Chunkit Tong Jia Liu Sravan G.Sreenivasmurthy Xinjie Guan Yuxuan Kan Aston Jiaxi Wu Alexis Shiying Huang Jieqiong Tan Kingho Cheung Juxian Song Min Li | 2022 | Acta Pharmaceutica Sinica B2022，12，4： | 2 |

| 4 | A 16-channel gated integrator for high-resolution energy spectroscopy systems显示文摘A 16-channel gated integrator(GI) module following semi-Gaussian shaping amplifiers was developed for high-resolution energy spectroscopy systems at Institute of Modern Physics,Chinese Academy of Sciences.This GI solved the ballistic deficit problem by integrating the signal until all the charge was collected from the detector at counting rates up to 100 K.In this paper,a fast shaper was used to optimize the gate logic to ensure nonlinearity of the GI less than 0.17%;and a novel compensation approach,to reduce the charge injection from the switches in the GI; and a T-switch configuration,to eliminate leakage current in the reset switch. | ZHOU Chaoyang SU Hong KONG Jie DONG Chengfu QIAN Yi YANG Haibo MA Xiaoli | 2012 | Nuclear Science and Techniques2012，23，4： | 1 |
