Fig. 1: The A. spinulosa genome.
From: The flying spider-monkey tree fern genome provides insights into fern evolution and arborescence
a, A. spinulosa’s arborescent habit. b, DNA methylation levels of three contexts (CG, CHG and CHH) in the genome, gene body and TE (Gypsy, Copia and EnSpm) space. TSS, transcription start site; TTS, transcription termination site. c, Gene family expansion and contraction among 12 plant species, including 3 bryophytes, 3 ferns, 1 lycophyte and 4 seed plants, and 1 outgroup species, Chara braunii. The tree was constructed using 134 single-copy orthologous genes. The red and blue numbers above the branches represent expansion and contraction events, respectively. The number at each node represents divergence time. d, WGD analysis. The cladogram shows the relative phylogenetic positions of two ancient WGDs in A. spinulosa with Ks plots for each species in Cyatheales displayed along the right edge and a summary of experimental and simulated MAPS analyses below. The shaded area in the MAPS summary shows the standard deviation for the gene tree simulations. Pj, Plagiogyria japonica; Da, Dicksonia antarctica; Sl, Sphaeropteris lepifera; As, A. spinulosa; Gp, Gymnosphaera podophylla; Gg, Gymnosphaera gigantea. e, Intragenomic synteny among 69 chromosomes in the A. spinulosa genome.
