Complete genome assembly of the desert moss Syntrichia caninervis and its symbiotic bacteria. (a) Complete circular genome of the symbiotic bacteria Paenibacillus sp., illustrated tracks included the GC skew (purple and green), GC content (grey) and the 6‐frame protein coding sequences (blue). (b) Collinearity analyses of the symbiotic bacterial genomic sequence with the three contigs of Paenibacillus cellulosilyticus (strain KACC 14175) genome. (c) Overview and comparison of the ScMoj v1 and ScGur T2T genomes. (d) Overview of the genomic syntenies between the ScGur T2T, ScMoj v1 and P. patens T2T genomes. (e) Chromosomal sequence synteny comparison and structural variations between the ScMoj v1 and ScGur T2T genome assemblies. (f) Photographs of desiccated and rehydrated S. caninervis gametophytes and a circos plot illustrated various genomic structures of the T2T genome. Plotted circos tracks illustrated (I) the 13 gapless chromosomes, (II) GC content, (III) gene density, (IV) coverage of repetitive sequences, (V) coverage of helitron elements, (VI) coverage of Gypsy LTR elements, (VII) coverage of Copia LTR elements, (VIII) centromeric regions identified from CENH3 protein‐binding peaks using cut&tag and (IX) intra‐genomic syntenies. Densities show the proportion of a 500‐kb window (400‐kb sliding step) of each genomic feature. (g, h) Sequence signature illustration of two exemplar centromeres of chromosome 1 (h) and 13 (i) indicated the Copia‐dominant centromeres in S. caniversis. The upper panel showed the StainedGlass sequence‐identity heatmaps, followed by coverage peaks from two independent CUT&Tag sequencing experiments and various types of repetitive elements. Copia and Gypsy elements are shown as pink and green rectangle, respectively; and intact Copia and Gypsy elements are shaded deep red and dark green, respectively.
