Extended Data Fig. 2 | Additional genome assembly data. a, Hi-C-based
Xenia sp. genome assembly. The scaffolds are separated by grids demarcated
by black lines. The numbers for the 15 longest scaffolds out of the total
168 scaffolds are shown. b, Size distribution of Xenia sp. genome scaffolds.
Each bar on the x axis represents a scaffold. c, Xenia sp. genome is predicted to
be diploid, as expected, with a haploid genome size of about 197 Mb, on the
basis of GenomeScope analysis of Illumina short reads. d, Contamination
analysis by BlobTools revealed a similar GC content and genomic coverage
across most scaffolds. Each coloured circle in the graph represents a scaffold.
Larger circles have longer scaffold lengths; the three grey circles provide the
length scale used in the plot. The colour codes represent the closest species
group that has the highest sequence similarities to the Xenia sp. scaffolds
(the first number in each set of parentheses shows the Xenia scaffold number
followed by the combined length of the scaffolds and scaffold N50 value
(minimum contig length needed to cover 50% of the combined scaffold length)
in Mb). e, A summary of Xenia sp. genome assembly and gene annotation.
