主 题:Soybean Telomere-to-Telomere assembly Zhonghuang 13 Structure variations
摘 要:Soybean(Glycine max)stands as a globally significant agricultural crop,and the comprehensive assembly of its genome is of paramount importance for unraveling its biological characteristics and evolutionary ***,previous soybean genome assemblies have harbored gaps and incompleteness,which have constrained in-depth investigations into ***,we present Telomere-to-Telomere(T2T)assembly of the Chinese soybean cultivar Zhonghuang 13(ZH13)genome,termed ZH13-T2T,utilizing PacBio Hifi and ONT ultralong *** employed a multi-assembler approach,integrating Hifiasm,NextDenovo,and Canu,to minimize biases and enhance assembly *** assembly spans 1,015,024,879 bp,effectively resolving all 393 gaps that previously plagued the reference *** annotation efforts identified 50,564 high-confidence protein-coding genes,707 of which are ***13-T2T revealed longer chromosomes,421 not-aligned regions(NARs),112 structure variations(SVs),and a substantial expansion of repetitive element compared to earlier ***,we identified 25.67 Mb of tandem repeats,an enrichment of 5S and 48S rDNAs,and characterized their genotypic *** summary,we deliver the first complete Chinese soybean cultivar T2T *** comprehensive annotation,along with precise centromere and telomere characterization,as well as insights into structural variations,further enhance our understanding of soybean genetics and evolution.
