title: Repeat region absent in mitochondrial genome of tube-dwelling diatom Berkeleya fennica (Naviculales, Bacillariophyceae).
abstract: The complete mitochondrial DNA of tube-dwelling diatom, Berkeleya fennica was sequenced and characterized. The circular mitogenome contains 63 genes in 35,509 bp (29.7% GC), including 36 protein-coding, 25 tRNA, 2 rRNA genes. Most of the protein-coding (27) genes have usual ATG start codon, except 9 genes such as ATA for rps8; ATC for rps14; ATT for rps12 and orf51; GTG for nad5; TTA for cox3, nad4 and orf147; and TTG for cob. The nad11 and rrs are the only interrupted genes in the mitogenome. Gene content and synteny of B. fennica are very similar to Phaeodactylum tricoruntum (NC_016739). Absence of repeat region in B. fennica resulted in mitogenome size difference to P. tricoruntum. A new mitogenome will provide useful information for mitochondrial genome diversity and evolution of the diatoms.
