520 _aEuphyllophytes encompass almost all extant plants, including two sister clades, ferns and seed plants. Decoding genomes of ferns is the key to deep insight into the origin of euphyllophytes and the evolution of seed plants. Here, we report a chromosome-level genome assembly of Adiantum capillus-veneris L., a model homosporous fern. This fern genome comprises 30 pseudochromosomes, with a size of 4.8-gigabase and a contig N50 length of 16.22 Mb. Gene co-expression network analysis uncovered that homospore development, in ferns, has relatively high genetic similarities with the pollen in seed plants. Analyzing fern defense response expanded the understanding of evolution and diversity in endogenous bioactive jasmonates in plants. Moreover, comparing ferns' genomes with those of other land plants reveals changes in gene families important for the evolutionary novelties, within the euphyllophyte clade. These results lay a foundation for studies on fern genome evolution and function, as well as the origin and evolution of euphyllophytes.
