The complete mitochondrial genome of Reticulitermes labralis and implications for Rhinotermitidae taxonomy.

ABSTRACT: The complete nucleotide sequence of the mitochondrial genome of Reticulitermes labralis was analyzed. This mitochondrial genome is a circular molecule of 15,914?bp in length and has the same gene content and organization as that found in other Reticulitermes species. It contains 13 protein-coding genes (PCGs), 22 tRNAs, two rRNAs (12S and 16S rRNA) and a non-coding AT-rich region (CR). The total base composition is strongly biased toward A?+?T nucleotides (65.1%). Most of the genes are encoded on the H strand, except for the other four protein-coding genes and eight tRNA genes on the L strand. The phylogenetic tree based on the nucleotide sequences of 13 mitochondrial PCGs using the Bayesian inference method supports the traditional morphologically analysis.

The complete mitochondrial genome of Reticulitermes periflaviceps (Isoptera: Rhinotermitidae).

Project description:The mitochondrial genome of the Reticulitermes periflaviceps contains 15,925 bp of nucleotide in length including 13 protein-coding genes, 22 transport RNAs, 2 ribosomal RNAs, and a non-coding region. The overall A + T among the genome sequence is 65.64%. The start codons of all protein-coding genes are ATN and the stop codon is TAA except TAG for Nad1 and incomplete T for COII and Nad5. The lengths of 12sRNA and 16sRNA genes are 743 and 1309 bp, respectively, and the control region was 1118 bp in length, with two repeating tandem regions. The phylogenetic tree revealed that R. periflaviceps and Reticulitermes kanmonensis constituted a sister group to Reticulitermes flaviceps.

The complete mitochondrial genome of the subterranean termite, Reticulitermes kanmonensis Takematsu, 1999 (Isoptera: Rhinotermitidae).

Project description:We have determined the mitochondrial genome of Reticulitermes kanmonensis Takematsu, 1999. The total length of the R. kanmonensis is 16,484?bp with 66.1% A?+?T content. It consists of 13 PCGs, 22 tRNA, 2 rRNA genes and an A?+?T-rich control region. All the protein-coding genes used ATN as start codon. But the stop codons were TAA, TAG, and an incomplete termination codon (T) abutting an adjacent tRNA gene. The A?+?T-rich control region was 1680?bp in length with 70.4% A?+?T content.

The development of adultoid reproductives and brachypterous neotenic reproductives from the last instar nymphs in Reticulitermes labralis (Isoptera: Rhinotermitidae): a comparative study.

Project description:Secondary reproductives develop primarily from nymphs. However, they have been rarely studied; in particular, the development of adultoid reproductives (AR) with floppy wings is still unclear. In this study, the change in juvenile hormone (JH) levels, vitellogenin gene expression, and oogenesis during the development of AR and brachypterous neotenic reproductives (BN) from the last instar nymphs of Reticulitermes labralis are investigated and compared. The results showed that the AR derived from the last instar nymphs by molting, and they were more similar to neotenic reproductives in morphology. In addition, the paired AR were not able to survive in the absence of workers. In R. labralis, the process of the last instar nymphs developing into AR and BN took an increase in JH level as a starting point. The JH level of the last instar nymphs molting into BN was approximately 1.5-fold higher than that of the AR. Additionally, The JHIII level of BN peaked on day 5, and that of AR peaked on day 10, which induced the onset of vitellogenesis in BN and AR, respectively. After molting, the vitellogenin gene expression levels of both BN and AR initially increased and then declined, and the expression levels in the BN were significantly higher than those in the AR. In addition, the oocytes of BN matured earlier than those of the AR, and the number of eggs laid by the BN was higher than the number laid by the AR. Our results demonstrate that, in R. labralis, the last instar nymphs can develop into AR, which are significantly different from BN in their development.

Complete Mitochondrial Genome of Papilio protenor (Lepidoptera, Papilionidae) and Implications for Papilionidae Taxonomy

Project description:Abstract The complete mitochondrial genome (mitogenome) of Papilio protenor (Lepidoptera: Papilionidae) was sequenced and annotated in this study. The mitogenome comprised a typical circular, double-stranded DNA molecule of 15,268 bp in length including 13 protein-coding genes (PCGs), two ribosomal RNA genes, 22 transfer RNA (tRNA) genes, and an A+T-rich region. The gene order and mitogenome orientation were similar to those of all known Papilionidae species. The nucleotide composition of the P. protenor mitogenome exhibits considerable A+T bias (80.5%) and the AT (?0.019) and GC (?0.231) skewness is slightly negative. All of the PCGs except for cytochrome c oxidase (COI) start with a canonical ATN start codon, whereas the COI gene is tentatively designated by the CGA codon. Of the 13 PCGs, 11 contain the complete stop codon TAA or TAG, whereas COI and COII were terminated with a single T nucleotide. All tRNAs exhibit the typical cloverleaf structure, except for tRNASer(AGN), which does not contain the dihydrouridine arm. The 458 bp A+T-rich region is comprised of nonrepetitive sequences including the motif ATAGA followed by a poly-T stretch and a microsatellite-like (AT)6 element preceded by the ATTTA motif. Phylogenetic analysis of the 13 PCGs data using Bayesian inference, maximum likelihood methods, and maximum parsimony support the view that the subfamily Parnassiinae is regarded as an independent subfamily within Papilionidae and that Zerynthiini should be treated as one of the two clades of the subfamily Parnassiinae along with Parnasiini. In addition, the analysis strongly supports the monophyly of the subfamily Parnassiinae.

The nest fungus of the lower termite Reticulitermes labralis.

Project description:Fitness-determining interactions with fungi have often been considered a by-product of social evolution in insects. In higher termites, the mutualistic association between the basidiomycete genus Termitomyces and Macrotermitinae is well known. However, whether and how lower termites use fungi is unclear. Here, we found a large amount of brown sclerotium-forming fungi in egg piles of the lower termite Reticulitermes labralis and identified the sclerotia as Fibulorhizoctonia sp. There was a significant difference in morphology between the sclerotia and the termite eggs. The workers of R. labralis and R. chinensis actively gathered the sclerotia into the egg piles within their nests, whereas the workers of R. aculabialis did not gather sclerotia outside their nests. None of the sclerotia in the egg piles germinated in the presence of workers. However, the sclerotia germinated in the absence of workers, and then the hyphae killed the termite eggs. The data from cellulase activity demonstrated that Fibulorhizoctonia sp. was able to exhaustively digest cellulose into glucose.We confirmed for the first time that the workers carrying the sclerotia into the piles of eggs is not due to mistaking the sclerotia for their eggs and that the workers of R. labralis may be able to select favourite fungi.
