Six Newly Sequenced Chloroplast Genomes From Quadriflagellate Chlamydomonadales (Chlorophyceae): Phylogeny and Comparative Genome Analyses.

ABSTRACT: Several quadriflagellate genera were revealed as the members of deep branches in Chlamydomonadales. However, the phylogenetic relationships among these quadriflagellate genera remained unresolved, and little information is known about the chloroplast genome structure for the chlamydomonadalean early-diverging lineages due to the limited data. In this study, we conducted phylogenetic and comparative genomic analyses with 6 newly sequenced quadriflagellate chlamydomonadalean chloroplast genomes. Four phylogenetic inferences based on different datasets recovered the robust topology, with Staurocarteria-Hafniomonas as the earliest-diverging lineage, followed by Corbierea within Chlamydomonadales and Spermatozopsis included in Sphaeropleales. The amino acid dataset combined with the site-hetero
