The complete chloroplast genome sequence of Ludwigia adscendens (L.) Hara, 1953 (Onagraceae)

Abstract

Ludwigia adscendens (L.) Hara, 1953 (L. adscendens) belongs to the family Onagraceae, which is a traditional medicinal plant distributed worldwide. In this study, the first complete chloroplast genome of L. adscendens was sequenced and assembled. The assembled chloroplast genome of L. adscendens is 159,560 bp in length, containing a pair of inverted repeat region A (IRA) of 24,762 bp, inverted repeat region B (IRB) of 24,762 bp, separated by a large single-copy (LSC) sequence of 90,276 bp and a small single-copy (SSC) region of 19, 760 bp, respectively. A total of 129 genes were annotated in the entire chloroplast genome, consisting of 37 transfer RNA (tRNA) genes, 8 ribosomal RNA (rRNA) genes, and 84 protein-coding genes, with a total GC content of 37.27%. The phylogenomic analysis showed that L. adscendens was closely related to L. octovalvis in the Onagraceae family. Further evolutionary studies of the genus Ludwigia could benefit from the complete chloroplast genome of L. adscendens present in this study and the obtained results would provide useful information for future phylogenetic, taxonomic, and evolutionary studies on Onagraceae.
