Abstract
The control region of the mitochondrial genomes shows high variation in conserved sequence organizations, which follow distinct evolutionary patterns in different species or taxa. In this study, we sequenced the complete mitochondrial genome of Lamellibrachia satsuma from the cold-seep region of Kagoshima Bay, as a part of whole genome study and extensively studied the structural features and patterns of the control region sequences. We obtained 15,037 bp of mitochondrial genome using Illumina sequencing and identified the non-coding AT-rich region or control region (354 bp, AT = 83.9%) located between trnH and trnR. We found 7 conserved sequence blocks (CSB), scattered throughout the control region of L. satsuma and other taxa of Annelida. The poly-TA stretches, which commonly form the stem of multiple stem-loop structures, are most conserved in the CSB-I and CSB-II regions. The mitochondrial genome of L satsuma encodes a unique repetitive sequence in the control region, which forms a unique secondary structure in comparison to Lamellibrachia luymesi. Phylogenetic analyses of all protein-coding genes indicate that L satsuma forms a monophyletic Glade with L. luymesi along with other tubeworms found in cold-seep regions (genera: Lamellibrachia, Escarpia, and Seepiophila). In general, the control region sequences of Annelida could be aligned with certainty within each genus, and to some extent within the family, but with a higher rate of variation in conserved regions.
