Characterization of the complete mitochondrial genome of Tylorida striata (Araneae: Tetragnathidae) and phylogenetic analysis

Abstract

The complete mitochondrial genome of Tylorida striata (GenBank accession number MN615900) is 14,422 bp in length with a high AT bias of 71.73%. It contains 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), 2 ribosomal RNA (rRNA) genes, and a putative control region. The gene order of T. striata was identical to other spider mitogenomes. Eleven tRNAs (trnW, trnY, trnC, trnD, trnG, trnL2, trnR, trnF, trnP, trnI, and trnL1) lose the TΨC-stems, whereas two tRNAs (trnS1 and trnS2) lack the dihydrouracil (DHU) arm. Phylogenetic tree based on concatenated amino acid sequences of 13 PCGs showed that T. striata is clustered with two Tetragnathidae species and recovered as sister of other two Tetragnathids.
