| 1 | Whole-Genome Resequencing of a Worldwide Collection of Rapeseed Accessions Reveals the Genetic Basis of Ecotype Divergence显示文摘Rapeseed (Brassica napus),an important oilseed crop,has adapted to diverse climate zones and latitudes by forming three main ecotype groups,namely winter,semiwinter,and spring types. However,genetic variations underlying the divergence of these ecotypes are largely unknown. Here,we report the global pattern of genetic polymorphisms in rapeseed determined by resequencing a worldwide collection of 991 germplasm accessions.A total of 5.56 and 5.53 million singlenucleotide polymorphisms (SNPs)as Well as 1.86 and 1.92 million InDels were identified by mapping reads to the reference genomes of 'Darmor-bzh'and 'Tapidor,'respectively.We generated a map of allelic drift paths that shows splits and mixtures of the main populations,and revealed an asymmetric evolution of the two subgenomes of B.napus by calculating the genetic diversity and linkage disequilibrium parameters.Selective-sweep analysis revealed genetic changes in genes orthologous to those regulating various aspects of plant development and response to stresses.A genome-wide association study identified SNPs in the promoter regions of FLOWERING LOCUS T and FLOWERING LOCUS C orthologs that corresponded to the different rapeseed ecotype groups. Our study provides important insights into the genomic footprints of rapeseed evolution and flowering-time divergence among three ecotype groups,and will facilitate screening of molecular markers for accelerating rapeseed breeding. | Dezhi Wu Zhe Liang Tao Yan Ying Xu Lijie Xuan Juan Tang Gang Zhou Ulrike Lohwasser Shuijin Hua Haoyi Wang Xiaoyang Chen Qian Wang Le Zhu Antony Maodzeka Nazim Hussain Zhilan Li Xuming Li Imran Haider Shamsi Ghulam Jilani Linde Wu Hongkun Zheng Guoping Zhang Boulos Chalhoub Lisha Shen Hao Yu Lixi Jiang | 2019 | Molecular Plant2019，12，1： | 10 |
| 2 | The genome and gene editing system of sea barleygrass provide a novel platform for cereal domestication and stress tolerance studies显示文摘The tribe Triticeae provides important staple cereal crops and contains elite wild species with wide geneticdiversity and high tolerance to abiotic stresses. Sea barleygrass (Hordeum marinum Huds.), a wildTriticeae species, thrives in saline marshlands and is well known for its high tolerance to salinity and waterlogging. Here, a 3.82-Gb high-quality reference genome of sea barleygrass is assembled de novo, with 3.69Gb (96.8%) of its sequences anchored onto seven chromosomes. In total, 41 045 high-confidence (HC)genes are annotated by homology, de novo prediction, and transcriptome analysis. Phylogenetics, nonsynonymous/synonymous mutation ratios (Ka/Ks), and transcriptomic and functional analyses provide genetic evidence for the divergence in morphology and salt tolerance among sea barleygrass, barley, andwheat. The large variation in post-domestication genes (e.g. IPA1 and MOC1) may cause interspecies differences in plant morphology. The extremely high salt tolerance of sea barleygrass is mainly attributed tolow Na+ uptake and root-to-shoot translocation, which are mainly controlled by SOS1, HKT, and NHX transporters. Agrobacterium-mediated transformation and CRISPR/Cas9-mediated gene editing systems weredeveloped for sea barleygrass to promote its utilization for exploration and functional studies of hubgenes and for the genetic improvement of cereal crops. | Liuhui Kuang Qiufang Shen Liyang Chen Lingzhen Ye Tao Yan Zhong-Hua Chen Robbie Waugh Qi Li Lu Huang Shengguan Cai Liangbo Fu Pengwei Xing Kai Wang Jiari Shao Feibo Wu Lixi Jiang Dezhi Wu Guoping Zhang | 2022 | Plant Communications2022，3，5： | 2 |

| 6 | The process of liquefi ed natural gas显示文摘In this paper,the analysis of liquefied natural gas process plant technology,into the device before the natural gas compression,and then through the MEA aqueous solution to remove CO2.Finally,the compressed water removed;clean natural gas before entering the liquefaction unit.In the liquefaction unit,the high pressure natural gas is cooled and liquefi ed deep.The required cooling capacity is obtained by circulating the gas turbine to drive the closed mixed refrigerant nitrogen,methane,ethylene,propane and other components,and liquefied natural gas(LNG),which is fi nally stored in an atmospheric tank through a liquefi ed natural gas container or liquefi ed natural gas tanker for distribution.The recycle of the recycle refrigerant is carried out by means of environmental conditions.The heating medium required during the installation process is the hot oil heated by the exhaust gas of the gas turbine.The liquefi ed gas in the liquefi ed natural gas tank is compressed to regenerate the desiccant and then sent to the gas turbine as the fuel gas. | Zhaoyin Jiang Lixi Peng Shiyao Chang Ping Ouyang | 2018 | Insight-Energy Science2018，1，1： | 0 |
