Diploid and tetraploid genomes of Acorus and the evolution of monocots

Monocots are a major taxon within flowering plants, have unique morphological traits, show extraordinary diversity in lifestyle, and have successfully colonized almost every habitat on Earth. To improve our understanding of their origin and evolution, we generated chromosome-level reference genomes of the diploid Acorus gramineus and the tetraploid A. calamus, the only two species from the family Acoraceae.
