Abstract

The complete mitochondrial genome of the pavlovophycean microalga Diacronema viridis CCMP 620 was sequenced and characterized. The circular mitogenome is a total 29,282 bp in length with 39.2% GC content and contains 47 genes, including 20 protein-coding, three rRNA, and 24 tRNA genes. The gene synteny of D. viridis and D. lutheri has been highly conserved; however, the gene content (absence of introns and ORFs) and repeat regions (3.7 kbp) of D. viridis contributed to significant difference of mitogenomes within the Diacronema.

Keywords: Diacronema viridis CCMP 620; Pavlovophyceae; haptophytes; mitochondrial genome.
