The complete plastid genome and phylogenetic analysis of Gracilaria spinulosa

Abstract

Gracilaria spinulosa is an economical species of marine red algae. The length of its plastid genome sequence is 179,082 bp; a total of 236 genes were determined, including 203 protein-encoding genes, 3 rRNA genes, 29 tRNA genes, 1 ribonuclease gene, and 1 intron inserted into the trnM gene. The gene content and structure of Gracilariaceae species were relatively well conserved. Phylogenetic analysis showed that G. spinulosa had a closer relationship with Gracilaria salicornia in Gracilaria. The complete plastid genome sequence provided will help the understanding of Gracilaria evolution.
