Transposable element (TE) amplification has been recognized as a driving force mediating
genome size expansion and evolution, but the consequences for shaping 3D genomic
architecture remains largely unknown in plants. Here, we report reference-grade genome
assemblies for three species of cotton ranging 3-fold in genome size, namely Gossypium
rotundifolium (K2), G. arboreum (A2), and G. raimondii (D5), using Oxford Nanopore
Technologies. Comparative genome analyses document the details of lineage-specific TE …

Transposable element (TE) ampli cation has been recognized as a driving force mediating
genome size expansion and evolution, but the effect on shaping of 3D genomic architecture
remains largely unknown in plants. Here, we report three reference-grade cotton genome
assemblies of Gossypium rotundifolium (K2), G. arboreum (A2) and G. raimondii (D5) using
Oxford Nanopore sequencing technology. Comparative genome analyses document the
details of lineage-speci c TE ampli cation contributing to three-fold change of genome size …
