摘要 | Tracing evolutionary history proves challenging for polyploid groups that have evolved rapidly, especially if an ancestor of a polyploid is extinct. The Ns-containing polyploids are recognized as the NsXm and StHNsXm genomic constitutions in Triticeae. The Ns originated from Psathyrostachys, while the Xm represented a genome of unknown origin. Here, we use genetic information in plastome to trace the complex lineage history of the Ns -containing polyploid species by sampling 26 polyploids and 90 diploid taxa representing 23 basic genomes in Triticeae. Phylogenetic reconstruction, cluster plot of genetic distance matrix, and migration event demonstrated that (1) the Ns plastome originated from different Psathyrostachys species, and the Xm plastome may originate from an ancestral lineage of Henrardia, Agropyron, and Eremopyrum; (2) the Ns, Xm, and St genome donors separately served as the maternal parents during the speciation of the Ns-containing polyploid species, resulting in a maternal haplotype polymorphism; (3) North American Leymus species might originate from colonization during late Miocene via the Bering land bridge and were the paternal donor of the StHNsXm genome Pascopyrum species. Our results shed new light on our understanding of the rich diversity and ecological adaptation of the Ns -containing polyploid species. |
