Abstract:
In order to fully comprehend the evolution and kinship of fishes in the family of Loricariidae, the complete
mitochondrial genome of the Loricariidae fish Ancistrus temmincki was firstly characterized in the
present study. The whole mitogenome was 16,657 bp in size and consisted of 13 protein-coding genes,
22 tRNAs, 2 rRNAs genes, a control region and origin of light-strand replication. The proportion of coding
sequences with a total length of 11,473 bp was 68.88%, which encoded 3,813 amino acids. The
genome composition was highly AþT biased (56.29%), and exhibited AT-skew (0.0661) and a negative
GC-skew (–0.2740). All protein-coding genes were started with ATG except for GTG in CO1, while
stopped with the standard TAN codons or a single T. The control region (D-loop) ranging from
15,635 bp to 16,657 bp was 1023 bp in size. Until now, there is hardly any studies on the complete
mitochondrial sequence in the genus of Ancistrus, phylogenetic analysis showed that A. temmincki was
most closely related to Ancistrus cryptophthalmus in the genus of Ancistrus. The complete mitochondrial
genome sequence has provided a new insight into the taxonomic classification, and a more complex
picture of the species diversity within the family of Loricariidae.
