Characterization of the complete mitochondrial genome of the striped soldier shrimp, Plesionika edwardsii (Brandt, 1851) (Crustacea: Decapoda: Pandalidae), and comparison with other species of Caridea Jiménez-Ruiz, Claudio Amador Robles Rodríguez, Francisca Navajas Pérez, Rafael Ruiz Rejón, Carmelo Herrán Moreno, Roberto De La Crustacea Mitogenome Mitogenome assembly This work was funded as part of a project of investigation, development, and innovation of the 2020 European Regional Development Fund program (B.BIO.678.UGR20) “Análisis genético de Plesionika edwardsii en poblaciones del Mar de Alborán (PLESIGEN)” (Genetic analysis of Plesionika edwardsii in populations of the Alborán Sea). The striped soldier shrimp, Plesionika edwardsii (Brandt, 1851) is a pandalid with economic value in the Mediterranean region. We have sequenced and assembled its complete mitochondrial genome, which is 15,956 bp in length and contains the same 37 genes found in most metazoan mitochondrial genomes. Its gene order and nucleotide content are similar to most of the caridean mitochondrial genomes. In the comparative analysis, however, we detected in other species changes in the gene order that could be mediated by the recombination of transfer RNA genes, as well as AT skew shifts that could indicate changes in the origins of replication. All protein-coding genes of the mitochondrial genome of P. edwardsii seem to be under purifying selection, although the differences in Ka:Ks ratios suggest a disparity in the mutational constraints of some genes. This genome also presents a 1,118 bp-long non-coding sequence that encompass the control region. We have been able to find a previously described conserved sequence block in this region and assess that it forms a stem-loop structure in different species of Pandalidae, which is a shared feature with the conserved sequence blocks described in the family Alvinocarididae. We also detected microsatellites in the control region of P. edwardsii and in other species of Pandalidae and minisatellites in Lysmata vittata (Stimpson, 1860) that can account for around 20% of the additional non-coding region of this species. The phylogenetic relationships of P. edwardsii with other pandalids were assessed by two analyses: one based on the complete mitochondrial sequences and another based only on the protein-coding genes. Our study, thus, contributes to the genomic resources available for P. edwardsii and expands the current biological knowledge about the mitochondrial genomes of other caridean species. 2024-01-19T09:00:40Z 2024-01-19T09:00:40Z 2022 journal article Claudio A Jimenez-Ruiz, Francisca Robles, Rafael Navajas-Pérez, Carmelo Ruiz-Rejón, Roberto de la Herrán, Characterization of the complete mitochondrial genome of the striped soldier shrimp, Plesionika edwardsii (Brandt, 1851) (Crustacea: Decapoda: Pandalidae), and comparison with other species of Caridea, Journal of Crustacean Biology, Volume 42, Issue 4 https://hdl.handle.net/10481/86940 10.1093/jcbiol/ruac055 eng http://creativecommons.org/licenses/by-nc-nd/3.0/ embargoed access Creative Commons Attribution-NonCommercial-NoDerivs 3.0 License
