1Analysis of genetic architecture and favorable allele usage of agronomic traits in a large collection of Chinese rice accessions显示文摘Genotyping and phenotyping large natural populations provide opportunities for population genomic analysis and genome-wide association studies(GWAS). Several rice populations have been re-sequenced in the past decade;however, many major Chinese rice cultivars were not included in these studies. Here, we report large-scale genomic and phenotypic datasets for a collection mainly comprised of 1,275 rice accessions of widely planted cultivars and parental hybrid rice lines from China. The population was divided into three indica/Xian and three japonica/Geng phylogenetic subgroups that correlate strongly with their geographic or breeding origins. We acquired a total of 146 phenotypic datasets for 29 agronomic traits under multi-environments for different subpopulations. With GWAS, we identified a total of 143 significant association loci, including three newly identified candidate genes or alleles that control heading date or amylose content. Our genotypic analysis of agronomically important genes in the population revealed that many favorable alleles are underused in elite accessions, suggesting they may be used to provide improvements in future breeding efforts. Our study provides useful resources for rice genetics research and breeding.Xiuxiu Li Zhuo Chen Guomin Zhang Hongwei Lu Peng Qin Ming Qi Ying Yu Bingke Jiao Xianfeng Zhao Qiang Gao Hao Wang Yunyu Wu Juntao Ma Liyan Zhang Yongli Wang Lingwei Deng Shanguo Yao Zhukuang Cheng Diqiu Yu Lihuang Zhu Yongbiao Xue Chengcai Chu Aihong Li Shigui Li Chengzhi Liang 2020Science China(Life Sciences)2020,63,11:8
2GmACP expression is decreased in Gm NORK knockdown transgenic soybean roots显示文摘NORK and soybean acyl carrier protein(ACP) both play important roles in nodulation.However,the relationship between Nod factor signaling and fatty acid(FA) biosynthesis during symbiotic development is unknown.In this study,an RNAi plasmid of Gm NORK was constructed and transformed into soybean roots by Agrobacterium rhizogene-mediated hairy-root transformation.The nodule number decreased substantially in Gm NORK knockdown soybean transgenic roots.To investigate the relationship between Gm ACP and Nod factor signaling,we measured Gm ACP expression levels in Gm NORK RNAi soybean transgenic roots and found that rhizobia inoculation led to substantially reduced Gm ACP expression.Thus,FA biosynthesis was affected by Nod factor signaling during nodule development in soybean,a finding that provides valuable information that improves our understanding of the functions of Gm NORK and Gm ACP in symbiotic signaling and nodule development.Lijun Wang Lingwei Deng 2016The Crop Journal2016,4,6:1
3A Study on the Cooperative Mechanism of the Belt and Road Initiative from the Perspective of New Regionalism显示文摘The loosely-typed, duty-overlapped and subject-isolated cooperative mechanism of the Belt and Road Initiative has significantly limited the advancement of the initiative and affected the full play of its cooperative effect. New Regionalism is a theory of international relations that concerns international cooperation at the regional level. Its characteristics of multilevel, multi-topic and multi-subject conform to the cooperation needs of the Belt and Road Initiative and provide a guiding framework for the cooperative mechanism of the Initiative. According to the theoretical connotation of New Regionalism, the cooperative mechanism of the Belt and Road Initiative should enrich its cooperation forms, deepen cooperation topics and promote the participation of 'State-Market-Society'. This mechanism is expected to form various cooperation models, comprehensive governance and diversified participants to enable the smooth advancement of the Belt and Road Initiative.Deng Tingting Ma Chunxue Wu Lingwei 2018Contemporary Social Sciences2018,3,1:1
4Extensive sequence divergence between the reference genomes of Taraxacum kok-saghyz and Taraxacum mongolicum显示文摘Plants belonging to the genus Taraxacum are widespread all over the world,which contain rubber-producing and non-rubberproducing species.However,the genomic basis underlying natural rubber(NR)biosynthesis still needs more investigation.Here,we presented high-quality genome assemblies of rubber-producing T.kok-saghyz TK1151 and non-rubber-producing T.mongolicum TM5.Comparative analyses uncovered a large number of genetic variations,including inversions,translocations,presence/absence variations,as well as considerable protein divergences between the two species.Two gene duplication events were found in these two Taraxacum species,including one common ancestral whole-genome triplication and one subsequent round of gene amplification.In genomes of both TK1151 and TM5,we identified the genes encoding for each step in the NR biosynthesis pathway and found that the SRPP and CPT gene families have experienced a more obvious expansion in TK1151 compared to TM5.This study will have large-ranging implications for the mechanism of NR biosynthesis and genetic improvement of NR-producing crops.Tao Lin Xia Xu Huilong Du Xiuli Fan Qingwen Chen Chunyan Hai Zijian Zhou Xiao Su Liquan Kou Qiang Gao Lingwei Deng Jinsheng Jiang Hanli You Yihua Ma Zhukuan Cheng Guodong Wang Chengzhi Liang Guomin Zhang Hong Yu Jiayang Li 2022Science China(Life Sciences)2022,65,3:0
