The structure and gene sequence of the fish mitochondrial genome are generally
considered to be conservative. However, two types of gene arrangements are found in the …

Mitochondrial genome rearrangements that result in control region duplication have been
described for a variety of birds, but the mechanisms leading to their appearance and …

Mitochondrial genomes are generally thought to be under selection for compactness, due to
their small size, consistent gene content, and a lack of introns or intergenic spacers. As more …

Background Although nowaday it is broadly accepted that mitochondrial DNA (mtDNA) may
undergo recombination, the frequency of such recombination remains controversial. Its …

Generally, a teleostean group possesses only one type or a set of similar mitochondrial
gene arrangement. However, two types of gene arrangement have been identified in the …

Mitochondrial genes are placed on one molecule, which implies that they should carry
consistent phylogenetic information. Following this advantage, we present a well-supported …

Background The animal mitochondrial genome is generally considered to be under
selection for both compactness and gene order conservation. As more mitochondrial …

Background Bird mitogenomes differ from other vertebrates in gene rearrangement. The
most common avian gene order, identified first in Gallus gallus, is considered ancestral for …

Mitochondrial genome (mitogenome) structure and gene order are generally considered
conserved in vertebrates. However, the flatfish (Pleuronectiformes) mitogenomes exhibit the …

Background The mitochondrial genomes (mitogenomes) of flatfishes (Pleuronectiformes)
exhibit highly diversified types of large-scale gene rearrangements. We have reported that …
