The complete chloroplast genome sequence of <i>Elatostema involucratum</i>

Here, we report the complete chloroplast genome of <i>E. involucratum</i> for the first time, assembled using high-throughput sequencing. The chloroplast genome is 150,481 bp in length, with an overall GC content of 36.35%, and exhibits the typical quadripartite structure, comprising a large single-copy (LSC) region of 84,035 bp, a small single-copy (SSC) region of 17,084 bp, and a pair of inverted repeat (IR) regions of 24,681 bp each.

A total of 128 genes were annotated, including 85 protein-coding genes, 35 tRNA genes, and 8 rRNA genes, most of which are associated with photosynthesis and self-replication. Phylogenetic analysis revealed that <i>E. involucratum</i> is most closely related to <i>E. stewardii</i>, followed by <i>E. suzukii</i>. This study enriches the chloroplast genomic resources for the genus <i>Elatostema</i>, and provides a valuable foundation for further research on its genetic evolution and germplasm development.</p>
