The complete mitochondrial genome sequence of Diaphorina citri (Hemiptera: Psyllidae)

Abstract

The first complete mitochondrial genome (mitogenome) sequence of Asian citrus psyllid, Diaphorina citri (Hemiptera: Psyllidae) from Guangzhou, China, is presented. The circular mitogenome is 14,996 bp in length with an A+T content of 74.5%, and contains 13 protein-coding genes (PCGs), 22 tRNA genes (tRNAs), two rRNA genes and an AT-rich control region. Synteny was identical to the ancestral insect mitogenomes. All PCGs start with ‘ATN’ codons. Eleven PCGs use the complete termination codons (‘TAA’ or ‘TAG’), while the remaining two (cox2 and nad5) use a single ‘T’ as the stop codon. All tRNAs have the typical cloverleaf structure, except for trnTrp which lacks the variable arm and trnSer (AGN) which lacks the dihydrouridine arm. A phylogenetic tree, including 12 members of Sternorrhyncha, was constructed based on the 13 PCGs sequences. The resulting phylogenetic tree matched the established taxonomic scheme based on morphology.
