Chloroplast genome sequencing and phylogenetic analysis of <i>Cyperus eragrostis</i> lam. (cyperaceae)

This study determined the chloroplast genome sequence of <i>Cyperus eragrostis</i> Lamarck. The total length of the genome was 184,646 bp with a GC content of 33.3%. It featured a quadripartite structure: a large single-copy region (101,639 bp), a small single-copy region (11,231 bp), and two inverted repeat regions (35,888 bp each). The genome contained 132 genes, including 87 coding sequences, 37 tRNAs, and eight rRNAs. Phylogenetic analysis revealed that <i>C. eragrostis</i> was closely related to <i>C. difformis</i>. This study provides chloroplast data for <i>C. eragrostis</i>, offering a fundamental resource for phylogenetic and evolutionary studies, and applied research such as invasion and conservation biology.
