Abstract

Keywords

The complete mitochondrial nucleotide sequence of Tirumala limniace is 15,285 bp in size, containing typical metazoan 37 genes: 13 protein-coding genes (PCGs), 22tRNA genes, 2 ribosomal RNA genes and one noncoding AT-rich region. All the 13 PCGs initiated with ATN, except for COI gene which is started by CGA codon. Nine PCGs use the complete termination codon (TAA), whereas the COI, COII, ND4 and ND5 genes end with single T. A total of 132 bp intergenic spacers and a total of 37 bp overlapping sequences are interspersed throughout the whole genome. The two rRNA genes (rrnL and rrnS) are 1352 bp and 779 bp in size, with their AT contents of 84.6% and 85.5%, respectively. All tRNA genes display typical secondary cloverleaf structures except for trnS1 (AGN) which loses DHU arm. The 438 bp long AT-rich region contains several features common to the other lepidopterans, such as the ATAGA motif followed by a 18 bp poly-T stretch, a 9 bp poly-T stretch, a 10 bp poly-A stretch and some microsatellite-like (AT)n elements.

Danainae, mitochondrial genome, nymphalidae, tirumala limniace

Danainae is a butterfly subfamily of Nymphalidae, which includes about 185 species, with most of the species being found in the tropical areas. However, up to the present, there are a lot of controversy about the taxonomy and phylogeny of Danainae, and therefore more mtDNA sequence data are needed to clarify this problem. However, only four complete mitogenomes of Danainae species have been reported, including Euploea mulciber

In this article, we reported the complete mitochondrial genome of another species of Danainae, the Tirumala limniace, in order to provide more useful information for the future phylogenetic and systematic studies.

In the column intergenic length, the positive number indicates interval base pairs between genes, while the negative number indicates the overlapping base pairs between genes.

The complete mitogenome of Tirumala limniace was a circular molecule of 15,285 bp in length, containing typical insect 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs) and 2 ribosomal RNA genes (rrnL and rrnS) and 1 major noncoding AT-rich region (Table 1). Its gene order and orientation are identical to those of other butterflies determined to date (Chen et al., 2014; Gan et al., 2014; Hao et al., 2013; Shi et al., 2012; Wang et al., 2011). Besides the AT-rich region, 12 intergenic spacers (132 bp in total) and 14 overlapping regions (37 bp in total) are dispersed throughout the whole genome. The mitogenome nucleotide skewness analysis (AT-skew ¼ 0.062, GC-skew ¼ 0.219) indicates a slight level of T and C skews. The total 13 PCGs was 11 170 bp long and all of them start with a typical ATN codon, except for the COI which uses CGA as its start codons (Table 1); nine PCGs stop with codon TAA, while the COI, COII, ND5, ND4 genes stop with the single nucleotide T (Table 1). This case was also frequently found in most insect mitogenomes sequenced to date (Cheng et al., 2014; Gan et al., 2014; Zhang et al., 2014). Like those of all other determined butterflies, All the Tirumala limniace tRNAs harbor the typical predicted secondary cloverleaf structures except for trnS1(AGN), whose dihydrouridine (DHU) arm is replaced by a simple loop (Chen et al., 2014; Servı´n-Garciduen˜as & Martı´nez-Romero, 2013; Shi et al., 2012, 2013; Shao et al., 2014). The two rRNAs (rrnL and rrnS) are 1318 bp and 786 bp long, with their AT contents of 84.6% and 85.5%, respectively. The T. limniace A+T-rich region is 438 bp long located between srRNA and Met-Ile-Gln tRNA cluster, exhibiting the highest A+T content (93.4%) of any region of the whole genome. Several short sequence repeats characteristic of lepidopterans are scattered throughout the whole region, such as a 18-bp poly T stretch preceded by the ATAGA motif, a microsatellite-like (AT)10 element. Additionally, some single nucleotides repeats which are frequently found in some other insect species, such as (T)2–9, (A)2–10, are also detected in the region (Chen et al., 2014; Cheng et al., 2014; Hao et al., 2012, 2013).

Nucleotide sequence accession number The complete genome sequence of T. limniace has been assigned GenBank accession number KJ784473.
