Abstract

Keywords

The mitochondrial genome (mitogenome) of Parara guttata (Hesperiidae: Hesperiinae) is a circular molecule of 15,441 bp in length, containing 37 typical animal mitochondrial genes: 13 protein-coding genes (PCGs), 2 ribosomal RNAs, 22 transfer RNAs and a non-coding AT-rich region. Its gene order and arrangement are identical to the common type found in most lepidopteran mitogenomes. All PCGs start with a typical ATN codon except for COI and ND1 which use CGA and GTG as their start codons, respectively. Some PCGs harbor TAG (ND1) or incomplete termination codon T (COI, COII, ND5, ND4), while others use standard TAA as their termination codons. The 411-bp long AT-rich region contains a conserved motif ATAGA followed by a 19-bp poly-T stretch and a microsatellite-like (TA)5 element preceded by the ATTTA motif.

Hesperiidae, Hesperiinae, mitochondrial genome, Parara guttata

Hesperiidae is one of the major groups in lepidopterans, encompassing about 3600 described species (Gorbunov, 2001). Due to its special morphological and behavioral characteristics, the skippers are commonly proposed to represent a separate group that is distinct from butterflies/moths in lepidopterans (Chiba & Eliot, 1991; Chou, 1998). In recent decades, mitochondrial DNA has been widely used as an informative molecular marker for diverse evolutionary studies (Boore, 1999; Krzywinski et al., 2006). However, within Hesperiidae, only three complete mitogenomes have been reported so far (Hao et al., 2012; Wang et al., 2013). Here, we present the complete mitogenome of another hesperid species, namely Parara guttata, aiming to provide more molecular data for the studies of Hesperiidae phylogeny. Whole mitogenome of P. guttata was amplified with 10 pairs of primers and completely sequenced by procedures of Sangon (China). The P. guttata mitogenoeme is 15,441 bp in length, which is the shortest in Hesperiidae determined so far. The whole genome contained 13 protein coding genes (PCGs), 2 ribosomal RNA genes, 22 putative tRNA genes and 1 non-coding AT-rich region (Table 1). Like those of the overwhelming majority of other lepidopterans, the nucleotide composition of the mitogenome is also remarkably AT biased (80.6%). Total 27 overlapping nucleotides are dispersed in 9 regions throughout the whole genome, with each region ranging from 1 to 8 bp; besides, 15 inter-genic spacer sequences totaling 269 bp are ranged from 1 to 99 bp and spread over the whole genome, with the longest one located between tRNAGln and ND2. All PCGs utilize the standard mitochondrial start codon ATN, except for COI and ND1 which use CGA and GTG as their start

codons, respectively. The start codon CGA of COI gene is well conserved, representing a synapomorphy characteristic of Lepidoptera (Gong et al., 2012; Kim et al., 2011), though the unconventional start codon GTG is also found in other lepidopteran mitogenomes, for example ND1 of Ochrogaster lunifer (Salvato et al., 2008) and COII of Sasakia charonda (Hakozaki, unpublished). Nine of the PCGs stop with codon TAN, while the COI, COII, ND5 and ND4 genes stop with the single nucleotide T (Table 1). All of the 22 tRNA genes, ranging from 61 to 71 bp, have a typical cloverleaf structure except for tRNASer(AGN), which loses its D-stem pairings in the DHU arm, and this case is the same with other determined lepidopterans (Kim et al., 2011; Park et al., 2012). The lrRNA and srRNA genes are 1368 bp and 778 bp, with the AT contents of 84.5% and 85.1%, respectively. The 411-bp long AT-rich region exhibits the highest AT content (90.8%) of the whole genome. Some structures characteristic of Lepidoptera (Kim et al., 2010), such as the repeated single nucleotides (T)2–9, (A)2–10 and the motif ATAGA followed by 19 bp poly-T stretches are presented in the region. Besides, a microsatellite-like (TA)5 element preceded by the ATTTA motif is also detected in the region. Nucleotide sequence accession number. The complete genome sequence of Parara guttata has been assigned GenBank accession number JX101619.
