The complete mitochondrial genome sequence of Dory snapper, Lutjanus fulviflamma, was determined by high-throughput sequencing (HTS) technique. The circular mitogenome of L. fulviflamma was 16,512 bp in length encoding 37 genes (13 proteins, 22 tRNAs, 2 ribosomal RNAs) and 2 conserved noncoding elements; the control region (D-Loop) and the origin of light strand synthesis (OL). Among the protein-coding genes, unusual start codons were identified in ND2, COX1 and ND3 genes and incomplete stop codons were identified in seven genes. Phylogenetic analysis with the currently known mitogenomes in genus Lutjanus revealed that L. fulviflamma was most closely related to Lutjanus russellii with 91% sequence identity.
ARTICLE HISTORY
The complete mitochondrial genome of spotted snakehead fish, Channa punctata (Bloch 1793) was determined by MiSeq platform. The genome was 16,409 bp in length, in which canonical 13 proteincoding genes, 22 tRNAs, 2 rRNAs, and a control region (D-Loop) were encoded. Relatively higher overall A þ T contents (53.70%) was identified compared with G þ C contents (46.30%). Among 13 protein-coding genes, only one unusual start condon (GTG) was identified in COX1, whereas six genes including COXII, COXIII, NAD2, NAD3, NAD4, and Cytb were ended with the incomplete stop codons (TA-/T-). Based on the currently identified mitogenomes of Channa fish species, C. punctata was most closely related to Channa gachua with 82% sequence identity.
The complete mitochondrial genome of the saw-jawed monocle bream, Scolopsis ciliata was determined by the next generation sequencing (NGS) technique. The circular mitogenome of S. ciliata (16,733 bp) encoded the canonical 37 genes including 13 proteins, 22 tRNA genes, 2 rRNAs (12S rRNA and 16S rRNA), and two non-coding regions; the origin of light strand replication (OL) and the putative control region (D-Loop). The gene arrangement of the S. ciliata mitogenome was identical to its relative, Scolopsis vosmeri. Phylogenetic analysis based on the full mitochondrial genome sequences showed that S. ciliata is most closely related to S. vosmeri with 83% nucleotide sequence identity. The mitogenome information of S. ciliata would be the useful information to understand the evolutional relationship of fishes in genus Scolopsis.
The mitochondrial genome of a blacktip sardinella, Sardinella melanura was determined by highthroughput sequencing (HTS) technique. The mitogenome of S. melanura (16,646 bp), encoded the canonical 37 mitochondrial structural genes (13 protein-coding genes (PCGs), 22 tRNA genes, two rRNA genes). The gene arrangement of S. melanura was identical to its relative species including Sardinella lemuru, Sardinella longiceps and Sardinella gibbosa. Except for COX1 (GTG), all the other PCGs showed the typical ATG as start codon. Incomplete stop codons were identified in ND2, COX2, COX3, ND3, ND4, and Cytb. The phylogenetic tree result showed that S. melanura was most closely related to S. jussieu, S. lemuru, and Sardinella maderansis with 83% identity, respectively.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
