Complete mitochondrial genome of Penaeus acehensis (Crustacea, Decapoda, Penaeidae) from Aceh province, Indonesia

Abstract

Penaeid shrimps are widely distributed from Indian to western Pacific Oceans and some which are economically important. In this study, we reported full mitochondrial genome of an endemic shrimp species, Penaeus acehensis, which inhabits exclusively in the coastal water of Aceh, Indonesia. Full length of circular mitogenome of P. acehensis was 15,991 bp in length, which contained 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and a control region. Start codons of all protein-coding genes were ATN except for COX1 in which ACG was used. Incomplete stop codon (T--) was found in five genes including COX2, COX3, NAD5, NAD4, and NAD4L. Among its relatives, P. acehensis was most closely related to Penaeus monodon showing 89% sequence identity in its mitogenome, which was corresponding to morphological analysis. Phylogenetic tree result showed that P. acehensis was clustered together with those were distributed in Indo-West Pacific region (clade II), which is distinct from Eastern Pacific region (clade I). ARTICLE HISTORYdistinct clades (Clade I and II), which implicate a geographical distribution. Shrimps inhabit in Eastern Pacific waters including P. acehensis, P. monodon, and P. indicus were clustered into Clade I, whereas those inhabit in Indo west Pacific waters were clustered into Clade II.

Characterization of complete mitochondrial genome of coonstriped shrimp Pandalus hypsinotus (Decapoda: Pandalidae)

“…According to the prediction by ARWEN (Laslett and Canb€ ack 2008), all 21 tRNA genes (63 bp to 73 bp) were able to be folded into the typical clover secondary structures except for tRNA-Ser (TCT) . The gene arrangement of P. hypsinotus was same to those from other decapods such as Charybdis bimaculata (Kim et al 2018) and Penaeus acehensis (Sektiana et al 2018). The putative control region (1041 bp) was located between 12S rRNA and tRNA-Ile gene.…”
