| Description |
Ramie is an economically important natural-fiber-producing crop that has been cultivated for thousands of years in China; however, the evolution of bast fiber remain largely unknown. Here we report a comprehensive analyses of ramie domestication based on the genome assembling and resequencing for cultivated and wild accessions. Two chromosome-level genomes representing the one of wild and cultivated ramie were de novo assembled. Pan-genome analysis discovered a mass of structural variations between two assemblies, and they together with the genetic variations from the population resequencing constituted a comprehensive genomic variation map of ramie. Selection analysis revealed that numerous fiber formation-related genes underwent potential selection, indicating that fiber yield was focused on for the selection during domesticated history. Taken together, this study sheds light on the domestication history of ramie and provides a valuable resource for the biological and breeding studies of this important crop. |
