The first complete chloroplast genome of Halodule uninervis (Forssk.) Boiss. 1882 (Cymodoceaceae)

Abstract

Halodule uninervis (Forssk.) Boiss. 1882 is a seagrass species. The complete chloroplast genome is 164,005 bp in length, with a GC content of 36.3%. This genome consists of a large single-copy region of 87,522 bp, a small single-copy region of 11,481 bp and a pair of inverse repeat regions of 32,501 bp each. A total of 131 genes were annotated in the genome, including 87 protein-coding genes, 36 tRNA genes, and 8 rRNA genes. Phylogenetic analysis revealed that H. uninervis shares the closest taxonomic relationship with Cymodocea rotundata and Syringodium isoetifolium, and all three species belong to the family Cymodoceaceae.
