Chromosome-Scale Genome Assembly for Soft-Stem Bulrush (Schoenoplectus tabernaemontani) Confirms a Clade-Specific Whole-Genome Duplication in Cyperaceae.

ABSTRACT: Schoenoplectus tabernaemontani (C. C. Gmelin) Palla is a typical macrophyte in diverse wetland ecosystems. This species holds great potential in decontamination applications and carbon sequestration. Previous studies have shown that this species may have experienced recent polyploidization. This would make S. tabernaemontani a unique model to study the processes and consequences of whole-genome duplications in the context of the well-documented holocentric chromosomes and dysploidy events in Cyperaceae. However, the inference was not completely solid because it lacked homology information that is essential to ascertain polyploidy. We present here the first chromosome-level genome assembly for S. tabernaemontani. By combining Oxford Nanopore Technologies (ONT) long reads and Illumina short
