Genomic insights into karyotype evolution and adaptive mechanisms of Polygonaceae species (PRJCA035374)
In this study, we performed de novo chromosome-scale genome assembly for seven Polygonaceae species, with the integration of four previously published genomes. A total of 11 species from 10 genera within the Polygonaceae family were chosen, representing 77% of the genera identified in China and displaying a diverse array of habitats. Then, we performed a comprehensive analysis on transposable elements (TEs) and the karyotype evolution across these 11 genomes, exploring their potential impact on the genomic architecture and potentially on adaptive strategies of the species. Moreover, we also conducted gene-based pan-genome construction and found that gCNVs were significantly correlated with the environmental adaptation of Polygonaceae species. Overall, this study offers valuable genomic resources for the evolutionary analysis of the Polygonaceae family and for understanding the adaptive mechanisms within this family in response to diverse habitats.
