Abstract
- The complete mitochondrial DNA of common planktonic diatom, Skeletonema marinoi JK029was sequenced and characterized. The circular mitogenome contains 62 genes in 38 515 bp(29.7% GC), including 35 protein-coding, 2 rRNA, and 25 tRNA genes. Total 80% of proteincodinggenes have usual ATG start codon and 20% have alternative start codons. The GCcontent of tRNA genes (39.8%) is relatively higher than those of the rRNA (32.9%) and CDS(29.3%). There are four cases of gene overlapping between neighboring genes, i.e., rrs-trnM,rps2-rps4, nad1-tatC, and rps11-trnY. Newly determined mitogenome of S. marinoi wascompared with available seven diatoms and eight stramenopiles by using the maximumlikelihoodanalysis. The 34-CDS concatenated data (8528 amino acids) support the monophylyof Bacillariophyta. However, mitogenome data showed different higher class-levels clusteringwith previous study. These results suggested that additional mitogenome data will provideuseful information for mitochondrial genome diversity and evolution of the diatoms andstramenopiles.es.
