The chromosome-level genome of water hyacinth (Eichhornia crassipes)

Water hyacinth (Eichhornia crassipes) is one of the most notorious invasive aquatic plants in the world and is known to cause significant ecological and socioeconomic impacts. Here, we reported a high-quality chromosome-level genome for water hyacinth, which will be a valuable reference for future investigations of its invasion.

A chromosome-level genome for water hyacinth was constructed by combing MGI short-reads sequencing, PacBio HiFi (High-fidelity) sequencing, and Hi-C sequencing, which resulted in ca. 1132.2 Mb in size the contig and scaffold N50 length of 18.76 Mb and 69.84 Mb, respectively. A total of 1024.36 Mb (90.47%) of the assembled sequences were anchored to 16 pseudochromosomes, dividing into subgenome A (468.72 Mb in size) and subgenome B (555.64 Mb in size). A total of 57,683 protein-coding genes were predicted, including 25,445 protein-coding genes for subgenome A and 27,992 protein-coding genes for subgenome B. Furthermore, the LAI and QV scores of the water hyacinth genome were 12.32 and 48.91, respectively.
