The complete mitochondrial genome and phylogeny of Diacronema viridis (Pavlovales, Pavlovophyceae).

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.
