| Abstract |
The crustacean isopod Armadillidium vulgare is characterized by an unusual approximately 42-kb-long mitochondrial genome consisting of two molecules co-occurring in mitochondria: a circular approximately 28-kb dimer formed by two approximately 14-kb monomers fused in opposite polarities and a linear approximately 14-kb monomer. Here we determined the nucleotide sequence of the fundamental monomeric unit of A. vulgare mitochondrial genome, to gain new insight into its structure and evolution. Our results suggest that the junction zone between monomers of the dimer structure is located in or near the control region. Direct sequencing indicated that the nucleotide sequences of the different monomer units are virtually identical. This suggests that gene conversion and/or replication processes play an important role in shaping nucleotide sequence variation in this mitochondrial genome. The only heteroplasmic site we identified predicts an alloacceptor tRNA change from tRNA(Ala) to tRNA(Val). Therefore, in A. vulgare, tRNA(Ala) and tRNA(Val) are found at the same locus in different monomers, ensuring that both tRNAs are present in mitochondria. The presence of this heteroplasmic site in all sequenced individuals suggests that the polymorphism is selectively maintained, probably because of the necessity of both tRNAs for maintaining proper mitochondrial functions. Thus, our results provide empirical evidence for the tRNA gene recruitment model of tRNA evolution. Moreover, interspecific comparisons showed that the A. vulgare mitochondrial gene order is highly derived compared to the putative ancestral arthropod type. By contrast, an overall high conservation of mitochondrial gene order is observed within crustacean isopods. |

This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 29 July 2022.
All research outputs
#6,346,487
of 22,986,950 outputs
Outputs from Journal of Molecular Evolution
#381
of 1,448 outputs
Outputs of similar age
#22,256
of 71,803 outputs
Outputs of similar age from Journal of Molecular Evolution
#2
of 9 outputs
Altmetric has tracked 22,986,950 research outputs across all sources so far. This one has received more attention than most of these and is in the 72nd percentile.
So far Altmetric has tracked 1,448 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.2. This one has gotten more attention than average, scoring higher than 73% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 71,803 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 68% of its contemporaries.
We're also able to compare this research output to 9 others from the same source and published within six weeks on either side of this one. This one has scored higher than 7 of them.
