The complete chloroplast genome of the marine microalgae Chaetoceros muellerii (Chaetoceroceae)

Abstract

In this study, the complete chloroplast genome of Chaetoceros muellerii was sequenced by using PacBio sequencing platform. The chloroplast genome was 116,284 bp in length, harboring a large single copy (LSC) region of 61,946 bp, a small single copy (SSC) region of 39,308 bp, and a pair of inverted repeats (IR) regions of 7515 bp. The overall GC content was 30.86%. The chloroplast genome of C. muellerii contained 131 genes in total, including 95 protein-coding genes, 30 transfer RNA (tRNA) genes and 6 ribosomal RNA (rRNA) genes. The phylogenetic analysis revealed that C. muellerii was closely related to Chaetoceros simplex with 100% bootstrap values. This study will contribute to the phylogenetic and taxonomic analysis of species in the family Chaetoceroceae.
