T2T gap-free genome assembly and genomic features of Scutellaria baicalensis. A Image of the S. baicalensis plant. B Visualization of gene density and the distribution of centromeress and telomere in the S. baicalensis genome. The scale represents chromosomes in a 500 kb window. C Landscape of the S. baicalensis genome assembly. The circles (outer to inner) represent: pseudochromosomes (Chr1 to Chr9), gene density, repetitive sequences density, GC content, and duplicated gene links (3934 gene pairs in total) within the genome. Chromosomes are shown in a 50 kb window.
