Cenchrus purpurascens cultivar:Liqiu Genome sequencing and assembly

We assembled a P. alopecuroides cv. 'Liqiu' genome at the chromosomal level with a size of approximately 845.71Mb, contig N50 of 84.83Mb, and genome integrity of 99.13% as assessed by CEGMA. A total of 833.41Mb sequences were mounted on 9 chromosomes by Hi-C technology. 60.66 % of the sequences and 34,312 genes were predicted. The completion of genome sequencing of P. alopecuroides cv. 'Liqiu' provides data support for mining high-quality genetic resources of P. alopecuroides, and provides theoretical basis for the origin and evolutionary characteristics of Pennisetum.
