title: The model barnacle Balanus balanus Linnaeus, 1758 (Crustacea: Maxillopoda: Sessilia) mitochondrial genome and gene rearrangements within the family Balanidae.
abstract: Balanus balanus Linnaeus, 1758, the model organism in the order Sessilia (Crustacea: Maxillopoda) is a cold water acorn barnacle in the family Balanidae distributing over the entire northern hemisphere. We present complete mitochondrial genome of this barnacle and analyze mitochondrial genomic characters of the family Balanidae. The length of mitochondrial genome is 15,955 bp, which is larger than those of the other barnacles in the same family. An inversion of a six-gene block (trnPro- nad4L- nad4- trnHis- nad5- trnPhe) is found between B. balanus and two Megabalanus (M. ajax and M. volcano). Three types of mitochondrial gene arrangements revealed in Balanidae have indicated the non-conserved gene orders even at intrafamilial level. Compared to pancrustacean ground pattern, large-scale gene rearrangements are found in B. balanus. Translocations of at least six tRNAs (trnAla, trnGlu/trnSer(AGY), trnPro/trnThr, trnLys, trnGln and trnCys) are identified and translocation and inversion occurred simultaneously in one tRNAs (trnTyr).
