Abstract

Syringodium isoetifolium (noodle seagrass) is a dioecious perennial seagrass. In this study, the complete chloroplast genome of S. isoetifolium was successfully characterized through next-generation sequencing technology. The cp genome was 159,333 bp in length with a GC content of 35.9%, including LSC (89,055 bp), SSC (19,160 bp), and two IRs (25,559 bp). The genome encoded 131 function genes, including 86 protein-coding genes, 37 tRNA genes, and eight rRNA genes. The phylogenetic analysis indicated that S. isoetifolium was clustered with Zostera and Ruppia.
