Abstract

Limnophila sessiliflora Blume 1826 is a perennial amphibious herb with ornamental and water purification value that is widespread in temperate and tropical Asia. In the present study, we sequenced, assembled, and annotated the complete chloroplast (cp) genome of L. sessiliflora. It is 152,395 bp in length, with a typical quadripartite structure, comprising a pair of inverted repeat regions (IRs; 25,545 bp), a large single-copy region (LSC; 83,163 bp), and a small single-copy (SSC; 18,142 bp) region. The whole cp genome contained 135 genes, including 89 protein-coding genes (PCGs), 38 transfer RNA (tRNA) genes, and eight ribosomal RNA (rRNA) genes. The maximum-likelihood (ML) phylogenetic analysis indicated that L. sessiliflora was closely related to the genera Bacopa and Scoparia in the tribe Gratioleae of Plantaginaceae. This cp genome provides a valuable genetic resource for phylogenetic study.
