Characterization of the complete mitochondrial genome of the green alga <i>Graesiella emersonii</i> GEGS21 (Chlorophyta).

ABSTRACT: Graesiella emersonii is a green microalga, belonging to the phylum Chlorophyta, with ecological and industrial significance. However, its phylogenetic position and mitogenome structure remain largely unexplored. We analyzed the complete mitogenome of G. emersonii GEGS21. This genome was 35,893 bp in length and contained 43 genes that comprised 13 protein-coding, six ribosomal RNA, and 24 transfer RNA genes. Phylogenetic analysis based on six protein-coding genes placed G. emersonii GEGS21 in a strongly supported clade with Pectinodesmus pectinatus, confirming its affiliation within the order Sphaeropleales. This study will provide valuable insights into the mitogenome architecture of G. emersonii, thereby contributing to further elucidation of green algal
