| 1 | Recent diagnostic developments at the 100 kJ-level laser facility in China显示文摘A 100 kJ-level laser facility has been designed to study inertial confinement fusion physics in China.This facility incorporates various diagnostic techniques,including optical,x-ray imaging,x-ray spectrum,and fusion product diagnostics,as well as general diagnostics assistance systems and central control and data acquisition systems.This paper describes recent developments in diagnostics at the facility. | Feng Wang Shaoen Jiang Yongkun Ding Shenye Liu Jiamin Yang Sanwei Li Tianxuan Huang Zhurong Cao Zhenghua Yang Xin Hu Wenyong Miao Jiyan Zhang Zhebin Wang Guohong Yang Rongqing Yi Qi Tang Longyu Kuang Zhichao Li Dong Yang Yulong Li Xiaoshi Peng Kuan Ren Baohan Zhang | 2020 | Matter and Radiation at Extremes2020，5，3： | 2 |
| 2 | Development and application of perfect SSR markers in cotton显示文摘Background:This study aimed to develop a set of perfect simple sequence repeat(SSR)markers with a single copy in the cotton genome,to construct a DNA fingerprint database suitable for authentication of cotton cultivars.We optimized the polymerase chain reaction(PCR)system for multi-platform compatibility and improving detection efficiency.Based on the reference genome of upland cotton and 10×resequencing data of 48 basic cotton germplasm lines,single-copy polymorphic SSR sites were identified and developed as diploidization SSR markers.The SSR markers were detected by denaturing polyacrylamide gel electrophoresis(PAGE)for initial screening,then fluorescence capillary electrophoresis for secondary screening.The final perfect SSR markers were evaluated and verified using 210 lines from different sources among Chinese cotton regional trials.Results:Using bioinformatics techniques,1246 SSR markers were designed from 26626 single-copy SSR loci.Adopting a stepwise(primary and secondary)screening strategy,a set of 60 perfect SSR markers was selected with high amplification efficiency and stability,easy interpretation of peak type,multiple allelic variations,high polymorphism information content(PIC)value,uniform chromosome distribution,and single-copy characteristics.A multiplex PCR system was established with ten SSR markers using capillary electrophoresis detection.Conclusions:A set of perfect SSR markers of cotton was developed and a high-throughput SSR marker detection system was established.This study lays a foundation for large-scale and standardized construction of a cotton DNA fingerprint database for authentication of cotton varieties. | WU Yuzhen HUANG Longyu ZHOU Dayun FU Xiaoqiong LI Chao WEI Shoujun PENG Jun KUANG Meng | 2020 | Journal of Cotton Research2020，3，3： | 2 |

| 5 | Genomic divergence in cotton germplasm related to maturity and heterosis显示文摘Commercial varieties of upland cotton(Gossypium hirsutum)have undergone extensive breeding for agronomic traits,such as fiber quality,disease resistance,and yield.Cotton breeding programs have widely used Chinese upland cotton source germplasm(CUCSG)with excellent agronomic traits.A better understanding of the genetic diversity and genomic characteristics of these accessions could accelerate the identification of desirable alleles.Here,we analyzed 10,522 high-quality singlenucleotide polymorphisms(SNP)with the CottonSNP63 K microarray in 137 cotton accessions(including 12 hybrids of upland cotton).These data were used to investigate the genetic diversity,population structure,and genomic characteristics of each population and the contribution of these loci to heterosis.Three subgroups were identified,in agreement with their knownpedigrees,geographical distributions,and times since introduction.For each group,we identified lineagespecific genomic divergence regions,which potentially harbor key alleles that determine the characteristics of each group,such as early maturity-related loci.Investigation of the distribution of heterozygous loci,among 12 commercial cotton hybrids,revealed a potential role for these regions in heterosis.Our study provides insight into the population structure of upland cotton germplasm.Furthermore,the overlap between lineagespecific regions and heterozygous loci,in the high-yield hybrids,suggests a role for these regions in cotton heterosis. | Shoupu He Gaofei Sun Longyu Huang Daigang Yang Panhong Dai Dayun Zhou Yuzhen Wu Xiongfeng Ma Xiongming Du Shoujun Wei Jun Peng Meng Kuang | 2019 | Journal of Integrative Plant Biology2019，61，8： | 0 |
