The complete chloroplast genome of a halophyte glasswort Salicornia europaea

Salicornia europaea is a salt-tolerant eudicot species in the Amaranthaceae family that is widely distributed in coastal wetlands and other saline-alkali lands. In this study, the complete chloroplast genome of S. europaea was determined using Illumina paired-end sequencing technology. The genome was 153,163 bp in length with 132 genes, including 87 protein-coding genes, 37 tRNA genes, and eight rRNA genes. The genome displayed a quadripartite structure consisting of a small single-copy (SSC) region of 18,953 bp, a large single-copy (LSC) region of 84,566 bp, and two inverted repeats (IRs) of 49,644 bp, respectively. The phylogenetic analysis indicated that Salicornia europaea exhibited the closest relationship with S. bigelovii. This study contributes to the pool of salt-tolerant gene species and serves as a valuable reference for further research on Salicornia.
