The complete chloroplast genome sequence of Ulva linza

Ulva linza is one of the causal species that result in the macroalgal blooms around Yellow Sea, China. The blooms have now become the world’s largest green tide, making great disaster for the ecosystem. We analyzed whole genome sequence of chloroplast for the first time (GenBank accession number KX058323). It was found that the annular-shape genome was made up of 86,726 bp, including 67 protein coding genes. We then aligned amino acids of chlorophyta species containing 44 common genes in series as phylogenetic tree, which shows Chlorophyceae and Trebouxiophyceae separately cluster except for Leptosiraterrestri. In the phylogenetic tree of amino acid alignment, Ulvophyceae, Pedinophyceae, Prasinophytes and Chlorophyta incertae sedis are independent cluster respectively, and closer to Trebouxiophyceae in the origin.
