I. sinensis morphology and genome assembly and annotation. (A) Morphological diagram of I. sinensis. The main body of the plant is 15 to 30 cm high, consisting of a rhizomatous and trilobed corm, with a tuft of roots at the base and long imbricate leaves at the top. The sporangia are basal and contain megaspores and/or microspores. The tissues analyzed using RNA sequencing are indicated by arrows. (B) Diagram depicts workflow for assembly of the I. sinensis genome from PacBio HiFi long reads, Illumina short reads, and Hi-C data. (C) Circos plot represents the I. sinensis genome, including (a) 22 assembled pseudochromosomes, (b) repeat content, (c) gene density, (d) pseudogene density, and (e) ncRNAs including lncRNAs, miRNAs, rRNAs, snoRNAs, snRNAs, and tRNAs. Blocks of synteny of at least 5 gene pairs between the genomes are connected by linked lines at the center of the Circos plot. Different colors represent different pseudochromosomes or syntenic blocks. A 500-kb window size was selected to slide on the genome, and the maximum repeat content and ncRNA content on each window were 1,696 and 1,146 respectively.
