Characterization of complete chloroplast genome of Ulva torta (Mertens) Trevisan, 1841

Abstract

Ulva torta (Mertens) Trevisan, 1841 was a global temperate widespread species. Green tide blooms caused by the green algae of the Ulva species occurred frequently in China. As a newly discovered species in the green tide bloom area, it was necessary to explore the relationship between U. torta and other green algae of the Ulva species. The complete chloroplast genome of U. torta was 105,423 bp in size. A total of 100 genes were annotated in the genome, containing 70 protein-coding genes, 27 transfer RNA (tRNA) genes, and three rRNA genes. The chloroplast genome had high AT content (74.76%). Phylogenetic analysis showed U. torta was clustered with Ulva meridionalis. This work could be useful for studying the evolution and genetic diversity of U. torta.
