Complete chloroplast genome of green alga Caulerpa sertularioides f. longipes (J.Agardh) Collins, 1909

Abstract

The complete chloroplast (cp) genome of Caulerpa sertularioides f. longipes was first assembled and characterized using Illumina pair-end sequencing from the South China Sea. It is 133,626 bp long, with a GC content of 32.94%. In total, 92 genes were identified in the genome, and they consisted 60 protein-coding genes (PCGs), 30 tRNA genes, and 2 rRNA genes. Like other species in Caulerpa, the whole cp genome of C. sertularioides f. longipes did not demonstrate an obvious quadripartite structure. A total of 31 microsatellites (SSRs) were identified in the cp genome using MISA. A phylogenetic tree revealed that C. sertularioides f. longipes was closer to Caulerpa cupressoides, which further clarified the phylogenetic relationships of species in Caulerpa.
