Overview of the Pennisetum giganteum genome assembly. a Morphology of P. giganteum. Scale bar = 50 cm. b Genome-wide Hi-C interaction map of P. giganteum. The heat map shows the intensity signal of the Hi-C chromosome interaction. c Circos representation of P. giganteum genome features. The outermost layer of blocks is a circular representation of the 14 pseudo-chromosomes, with scale mark at each 10 Mb (I). Density of protein-coding genes (II), GC content (III), LTR/Copia (IV), LTR/Gypsy (V), and genome-wide heterozygous single-nucleotide polymorphisms (SNPs) (VI) computed using a 100-kb non-overlapping window. The innermost track shows inter-chromosomal synteny relationship, with colored links that represent syntenic blocks between the two subgenomes
