Ramie (Boehmeria nivea) is an economically important natural fiber-producing crop that has been cultivated for thousands of years in China; however, the evolution this remains largely unknown. Here, we report a ramie domestication analysis based on genome assembly and resequencing wild accessions. Two chromosome-level genomes representing were assembled de novo. Numerous structural variations between two assemblies, together with genetic from population resequencing, constituted comprehensive genomic variation map ramie. Domestication identified 71 high-confidence selective sweeps comprising 320 predicted genes, 29 genes associated fiber growth expression. In addition, seven loci yield trait segregated derived crossing accessions, which showed overlap sweeps. These findings indicated bast traits focused during history This study sheds light provides valuable resource biological breeding studies crop.
