Comparative Genomics/Transcriptomics Marchant, Daniel Blaine [1], Sessa, Emily [2], Wolf, Paul [3], Soltis, Pamela S. [4], Soltis, Douglas [5]. Incorporating a fern genome into land plant evolutionary genomics. Ferns are infamous for large genomes, numerous chromosomes, and rampant polyploidy. As a result, they have been largely avoided for large-scale plant genomics projects, however, much can be learned from the sister group to seed plants. Here we present our findings from the draft genome of Ceratopteris richardii, or C-Fern. We compare the repeat composition and transposable element evolution of this 11.25 Gb genome to those of other land plants and find evidence for a relatively low rate of polyploidy despite a haploid chromosome number of 39. In addition, we find life phase specificity in both the genes and isoforms of this species.
