  1. Genetic differentiation for nuclear, mitochondrial and chloroplast genomes in common wild rice ( Oryza rufipogon Griff.) and cultivated rice ( Oryza sativa L.)
    Sun Q, Wang K, Yoshimura A, Doi K
    Theor Appl Genet, 2002 Jun;104(8):1335-1345.
    PMID: 12582589
    The genetic differentiation of nuclear, mitochondrial (mt) and chloroplast (cp) genomes was investigated by Southern and PCR analysis using 75 varieties of cultivated rice ( Oryza sativa L.) and 118 strains of common wild rice (CWR, Oryza rufipogon Griff.) from ten countries of Asia. The distinguishing differences between the Indica and Japonica cultivars were detected both in the nuclear genome and the cytoplasmic genome, confirming that the Indica-Japonica differentiation is of major importance for the three different classes of genome in cultivated rice. This differentiation was also detected in common wild rice with some differences among the genome compartments and the various regions. For nuclear DNA variation, both Indica-like and Japonica-like types were observed in the Chinese CWR, with the latter more-frequent than the former. No Japonica-like type was found in South Asia, and only two strains of the Japonica-like type were detected in Southeast Asia, thus the Indica-like type is the major type among South and Southeast Asian CWR. For mtDNA, only a few strains of the Japonica-like type were detected in CWR. For cpDNA, the Japonica type was predominant among the CWR strains from China, Bangladesh and Burma, while the Indica type was predominant among the CWR strains from Thailand, Malaysia, Cambodia and Sri Lanka, and both types were found in similar frequencies among the Indian CWR. Altogether, however, the degree of Indica-Japonica differentiation in common wild rice was much-less important than that in cultivated rice. Cluster analyses for nuclear and mitochondrial DNA variation revealed that some CWR strains showed large genetic distances from cultivated rice and formed clusters distinct from cultivated rice. Coincidence in the genetic differentiation between the three different classes of genome was much higher in cultivated rice than in CWR. Among the 75 cultivars, about 3/4 entries were "homoeotype" showing congruent results for nuclear, mt and cpDNA regarding the Indica-Japonica differentiation. In CWR, the proportions of homoeotypes were 5.7%, 15% and 48.8% in China, South Asia and Southeast Asia, respectively. Based on the average genetic distance among all the strains of CWR and cultivated rice for nuclear and mitochondrial genomes, the variability of the nuclear genome was found to be higher than that of the mitochondrial genome. The global pattern based on all genomes shows much-more diversification in CWR than that in cultivated rice.

  2. Heteroplasmy, length, and sequence characterization of the mitochondrial control region in Tomistoma schlegelii
    Kaur T, Ong AH
    Biochem Genet, 2011 Oct;49(9-10):562-75.
    PMID: 21461907 DOI: 10.1007/s10528-011-9431-y
    This study describes the organization of the repetitive pattern in the mtDNA control region of Tomistoma schlegelii. Using newly designed primers, we detected length variations of approximately 50-100 bp among individuals, and only one individual showed a heteroplasmic band. Sequencing the region after CSB III revealed two main patterns: a repeat motif and a variable number tandem repeat (VNTR) pattern. The VNTR region, with a core unit of 104 bp, consisting of four motifs and a short AT chain, is implicated in the length variation seen among individuals of Tomistoma. A conserved motif seen in a family unit indicated that the repeat pattern was stably inherited from the maternal parent to all offspring. A combination of VNTR patterns specific to different crocodilians was seen in Tomistoma, and the overall secondary structure was shown to be similar to that in Crocodylus and Gavialis.

  3. Fulltext Development of swine-specific DNA markers for biosensor-based halal authentication
    Ali ME, Hashim U, Kashif M, Mustafa S, Che Man YB, Abd Hamid SB
    Genet. Mol. Res., 2012;11(2):1762-72.
    PMID: 22843053 DOI: 10.4238/2012.June.29.9
    The pig (Sus scrofa) mitochondrial genome was targeted to design short (15-30 nucleotides) DNA markers that would be suitable for biosensor-based hybridization detection of target DNA. Short DNA markers are reported to survive harsh conditions in which longer ones are degraded into smaller fragments. The whole swine mitochondrial-genome was in silico digested with AluI restriction enzyme. Among 66 AluI fragments, five were selected as potential markers because of their convenient lengths, high degree of interspecies polymorphism and intraspecies conservatism. These were confirmed by NCBI blast analysis and ClustalW alignment analysis with 11 different meat-providing animal and fish species. Finally, we integrated a tetramethyl rhodamine-labeled 18-nucleotide AluI fragment into a 3-nm diameter citrate-tannate coated gold nanoparticle to develop a swine-specific hybrid nanobioprobe for the determination of pork adulteration in 2.5-h autoclaved pork-beef binary mixtures. This hybrid probe detected as low as 1% pork in deliberately contaminated autoclaved pork-beef binary mixtures and no cross-species detection was recorded, demonstrating the feasibility of this type of probe for biosensor-based detection of pork adulteration of halal and kosher foods.

    PMID: 23631365 DOI: 10.3109/19401736.2013.792066
    We sequenced the complete mitochondrial genome of the Tioman Island rock gecko, Cnemaspis limi, which is known as an endemic species to Malaysia. The complete mitogenome is 16,680 bp in size, consisting of 37 genes coding for 13 proteins, 22 transfer RNAs, two ribosomal RNAs and one control region. The A + T content of the overall base composition of H-strand is 53.09% (T: 23.20%, C: 32.48%, A: 29.89% and G: 14.43%). The major non-coding region (control region) is 1254 bp in length with the A + T content of 55.09% and four replicates of a 76-bp repeat within this region.

    Norfatimah MY, Teh LK, Salleh MZ, Mat Isa MN, SitiAzizah MN
    Gene, 2014 Sep 15;548(2):263-9.
    PMID: 25042454 DOI: 10.1016/j.gene.2014.07.044
    This is the first documentation of the complete mitochondrial genome sequence of the Malaysian Mahseer, Tor tambroides. The 16,690 bp mitogenome with GenBank accession number JX444718 contains 13 protein genes, 22 tRNAs, two rRNAs, and a noncoding control region (D-loop) as is typical of most vertebrates. The phylogenomic reconstruction of this newly generated data with 21 Cypriniformes GenBank accession ID concurs with the recognized status of T. tambroides within the subfamily Cyprininae. This is in agreement with previous hypotheses based on morphological and partial mitochondrial analyses.

  6. The mitogenome of Pangasius sutchi (Teleostei, Siluriformes: Pangasiidae)
    Zhao H, Kong X, Zhou C
    Mitochondrial DNA, 2014 Oct;25(5):342-4.
    PMID: 23795847 DOI: 10.3109/19401736.2013.800492
    The Pangasius sutchi is an important ornamental and economic fish in Southeast Asia e.g. Thailand, Malaysia and China. The complete mitochondrial genome sequence of P. sutchi has been sequenced, which contains 22 tRNA genes, 13 protein-coding genes, 2 rRNA genes and a non-coding control region with the total length of 16,522 bp. The gene order and composition are similar to most of other vertebrates. Just like most other vertebrates, the bias of G and C was found in different region/genes statistics results. Most of the genes are encoded on heavy strand, except for eight tRNA and ND6 genes. The mitogenome sequence of P. sutchi would contribute to better understand population genetics, evolution of this lineage.

  7. Fulltext Integrated shotgun sequencing and bioinformatics pipeline allows ultra-fast mitogenome recovery and confirms substantial gene rearrangements in Australian freshwater crayfishes
    Gan HM, Schultz MB, Austin CM
    BMC Evol. Biol., 2014;14:19.
    PMID: 24484414 DOI: 10.1186/1471-2148-14-19
    Although it is possible to recover the complete mitogenome directly from shotgun sequencing data, currently reported methods and pipelines are still relatively time consuming and costly. Using a sample of the Australian freshwater crayfish Engaeus lengana, we demonstrate that it is possible to achieve three-day turnaround time (four hours hands-on time) from tissue sample to NCBI-ready submission file through the integration of MiSeq sequencing platform, Nextera sample preparation protocol, MITObim assembly algorithm and MITOS annotation pipeline.

  8. Fulltext Mitogenomic phylogeny of the common long-tailed macaque (Macaca fascicularis fascicularis)
    Liedigk R, Kolleck J, Böker KO, Meijaard E, Md-Zain BM, Abdul-Latiff MA, et al.
    BMC Genomics, 2015 Mar 21;16:222.
    PMID: 25887664 DOI: 10.1186/s12864-015-1437-0
    BACKGROUND: Long-tailed macaques (Macaca fascicularis) are an important model species in biomedical research and reliable knowledge about their evolutionary history is essential for biomedical inferences. Ten subspecies have been recognized, of which most are restricted to small islands of Southeast Asia. In contrast, the common long-tailed macaque (M. f. fascicularis) is distributed over large parts of the Southeast Asian mainland and the Sundaland region. To shed more light on the phylogeny of M. f. fascicularis, we sequenced complete mitochondrial (mtDNA) genomes of 40 individuals from all over the taxon's range, either by classical PCR-amplification and Sanger sequencing or by DNA-capture and high-throughput sequencing.

    RESULTS: Both laboratory approaches yielded complete mtDNA genomes from M. f. fascicularis with high accuracy and/or coverage. According to our phylogenetic reconstructions, M. f. fascicularis initially diverged into two clades 1.70 million years ago (Ma), with one including haplotypes from mainland Southeast Asia, the Malay Peninsula and North Sumatra (Clade A) and the other, haplotypes from the islands of Bangka, Java, Borneo, Timor, and the Philippines (Clade B). The three geographical populations of Clade A appear as paraphyletic groups, while local populations of Clade B form monophyletic clades with the exception of a Philippine individual which is nested within the Borneo clade. Further, in Clade B the branching pattern among main clades/lineages remains largely unresolved, most likely due to their relatively rapid diversification 0.93-0.84 Ma.

    CONCLUSIONS: Both laboratory methods have proven to be powerful to generate complete mtDNA genome data with similarly high accuracy, with the DNA-capture and high-throughput sequencing approach as the most promising and only practical option to obtain such data from highly degraded DNA, in time and with relatively low costs. The application of complete mtDNA genomes yields new insights into the evolutionary history of M. f. fascicularis by providing a more robust phylogeny and more reliable divergence age estimations than earlier studies.

  9. MitoPhAST, a new automated mitogenomic phylogeny tool in the post-genomic era with a case study of 89 decapod mitogenomes including eight new freshwater crayfish mitogenomes
    Tan MH, Gan HM, Schultz MB, Austin CM
    Mol Phylogenet Evol, 2015 Apr;85:180-8.
    PMID: 25721538 DOI: 10.1016/j.ympev.2015.02.009
    The increased rate at which complete mitogenomes are being sequenced and their increasing use for phylogenetic studies have resulted in a bioinformatic bottleneck in preparing and utilising such data for phylogenetic analysis. Hence, we present MitoPhAST, an automated tool that (1) identifies annotated protein-coding gene features and generates a standardised, concatenated and partitioned amino acid alignment directly from complete/partial GenBank/EMBL-format mitogenome flat files, (2) generates a maximum likelihood phylogenetic tree using optimised protein models and (3) reports various mitochondrial genes and sequence information in a table format. To demonstrate the capacity of MitoPhAST in handling a large dataset, we used 81 publicly available decapod mitogenomes, together with eight new complete mitogenomes of Australian freshwater crayfishes, including the first for the genus Gramastacus, to undertake an updated test of the monophyly of the major groups of the order Decapoda and their phylogenetic relationships. The recovered phylogenetic trees using both Bayesian and ML methods support the results of studies using fragments of mtDNA and nuclear markers and other smaller-scale studies using whole mitogenomes. In comparison to the fragment-based phylogenies, nodal support values are generally higher despite reduced taxon sampling suggesting there is value in utilising more fully mitogenomic data. Additionally, the simple table output from MitoPhAST provides an efficient summary and statistical overview of the mitogenomes under study at the gene level, allowing the identification of missing or duplicated genes and gene rearrangements. The finding of new mtDNA gene rearrangements in several genera of Australian freshwater crayfishes indicates that this group has undergone an unusually high rate of evolutionary change for this organelle compared to other major families of decapod crustaceans. As a result, freshwater crayfishes are likely to be a useful model for studies designed to understand the evolution of mtDNA rearrangements. We anticipate that our bioinformatics pipeline will substantially help mitogenome-based studies increase the speed, accuracy and efficiency of phylogenetic studies utilising mitogenome information.

  10. Fulltext Soup to Tree: The Phylogeny of Beetles Inferred by Mitochondrial Metagenomics of a Bornean Rainforest Sample
    Crampton-Platt A, Timmermans MJ, Gimmel ML, Kutty SN, Cockerill TD, Vun Khen C, et al.
    Mol Biol Evol, 2015 Sep;32(9):2302-16.
    PMID: 25957318 DOI: 10.1093/molbev/msv111
    In spite of the growth of molecular ecology, systematics and next-generation sequencing, the discovery and analysis of diversity is not currently integrated with building the tree-of-life. Tropical arthropod ecologists are well placed to accelerate this process if all specimens obtained through mass-trapping, many of which will be new species, could be incorporated routinely into phylogeny reconstruction. Here we test a shotgun sequencing approach, whereby mitochondrial genomes are assembled from complex ecological mixtures through mitochondrial metagenomics, and demonstrate how the approach overcomes many of the taxonomic impediments to the study of biodiversity. DNA from approximately 500 beetle specimens, originating from a single rainforest canopy fogging sample from Borneo, was pooled and shotgun sequenced, followed by de novo assembly of complete and partial mitogenomes for 175 species. The phylogenetic tree obtained from this local sample was highly similar to that from existing mitogenomes selected for global coverage of major lineages of Coleoptera. When all sequences were combined only minor topological changes were induced against this reference set, indicating an increasingly stable estimate of coleopteran phylogeny, while the ecological sample expanded the tip-level representation of several lineages. Robust trees generated from ecological samples now enable an evolutionary framework for ecology. Meanwhile, the inclusion of uncharacterized samples in the tree-of-life rapidly expands taxon and biogeographic representation of lineages without morphological identification. Mitogenomes from shotgun sequencing of unsorted environmental samples and their associated metadata, placed robustly into the phylogenetic tree, constitute novel DNA "superbarcodes" for testing hypotheses regarding global patterns of diversity.

    Yong HS, Song SL, Eamsobhana P, Goh SY, Lim PE
    Acta Trop, 2015 Dec;152:157-164.
    PMID: 26348256 DOI: 10.1016/j.actatropica.2015.09.001
    Angiostrongylus cantonensis is a zoonotic parasite that causes eosinophilic meningitis in humans. Earlier work on its mitochondrial genome was based on long polymerase chain reaction method. To date, only the mitogenome of the isolates from China has been studied. We report here the complete mitogenome of the Thailand isolate based on next generation sequencing and compare the genetic diversity with other isolates. The mitogenome of the Thailand isolate (13,519bp) is longer than those of the China isolates (13,497-13,502bp). Five protein-coding genes (atp6, cox1, cox2, cob, nad2) show variations in length among the isolates. The stop codon of the Thailand isolate differs from the China and Taiwan isolates in 4 genes (atp6, cob, nad2, nad6). Additionally, the Thailand isolate has 4 incomplete T stop codon compared to 3 in the China and Taiwan isolates. The control region is longer in the Thailand isolate (258bp) than the China (230-236bp) and Taiwan (237bp) isolates. The intergenic sequence between nad4 and cox1 genes in the Thailand isolate lacks 2bp (indels) at the 5'-end of the sequence as well as differs at 7 other sites compared to the China and Taiwan isolates. In the Thailand isolate, 18 tRNAs lack the entire TΨC-arm, compared to 17 in the China isolate and 16 in the Taiwan isolate. Phylogenetic analyses based on 36 mt-genes, 12 PCGs, 2 rRNA genes, 22 tRNA genes and control region all indicate closer genetic affinity between the China and Taiwan isolates compared to the Thailand isolate. Based on 36 mt-genes, the inter-isolate genetic distance varies from p=3.2% between China and Taiwan isolates to p=11.6% between Thailand and China isolates. The mitogenome will be useful for population, phylogenetics and phylogeography studies.

    Sci Rep, 2015;5:15155.
    PMID: 26472633 DOI: 10.1038/srep15155
    The whole mitochondrial genome of the pest fruit fly Bactrocera arecae was obtained from next-generation sequencing of genomic DNA. It had a total length of 15,900 bp, consisting of 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and a non-coding region (A + T-rich control region). The control region (952 bp) was flanked by rrnS and trnI genes. The start codons included 6 ATG, 3 ATT and 1 each of ATA, ATC, GTG and TCG. Eight TAA, two TAG, one incomplete TA and two incomplete T stop codons were represented in the protein-coding genes. The cloverleaf structure for trnS1 lacked the D-loop, and that of trnN and trnF lacked the TΨC-loop. Molecular phylogeny based on 13 protein-coding genes was concordant with 37 mitochondrial genes, with B. arecae having closest genetic affinity to B. tryoni. The subgenus Bactrocera of Dacini tribe and the Dacinae subfamily (Dacini and Ceratitidini tribes) were monophyletic. The whole mitogenome of B. arecae will serve as a useful dataset for studying the genetics, systematics and phylogenetic relationships of the many species of Bactrocera genus in particular, and tephritid fruit flies in general.

  13. Fulltext Role of mitochondrial DNA mutations in brain tumors: A mini-review

    J Cancer Res Ther, 2015 Jul-Sep;11(3):535-44.
    PMID: 26458578 DOI: 10.4103/0973-1482.161925
    Brain tumor is molecularly a heterogeneous group of diseases, and genetic factors seem to play a crucial role in its genesis. Even though multiple alterations in the nuclear-encoded genes such as tumor suppressor and oncogenes are believed to play a key role in brain tumorigenesis, the involvement of the mitochondrial genome to this event remains controversial to date. Mitochondrial DNA (mtDNA) has been suspected to be associated with the carcinogenesis because of its high sensitivity to mutations and inefficient repair mechanisms in comparison to nuclear DNA. Thus, defects in mtDNA could also lead to the development of brain tumor. By virtue of their clonal nature and high copy number, mtDNA mutations may provide a new effective molecular biomarker for the cancer detection. It has been suggested that establishing mtDNA defective pattern might be useful in cancer diagnostics and detection, the prognosis of cancer outcome, and/or the response to certain treatments. This mini-review gives a brief overview on the several aspects of mtDNA, with a particular focus on its role in tumorigenesis and progression of brain tumor. Understanding the role of mitochondria and brain tumor development could potentially translate into therapeutic strategies for patients with these tumors.

  14. Fulltext Mitochondrial Genome Supports Sibling Species of Angiostrongylus costaricensis (Nematoda: Angiostrongylidae)
    Yong HS, Song SL, Eamsobhana P, Goh SY, Lim PE, Chow WL, et al.
    PLoS One, 2015;10(7):e0134581.
    PMID: 26230642 DOI: 10.1371/journal.pone.0134581
    Angiostrongylus costaricensis is a zoonotic parasitic nematode that causes abdominal or intestinal angiostrongyliasis in humans. It is endemic to the Americas. Although the mitochondrial genome of the Brazil taxon has been published, there is no available mitochondrial genome data on the Costa Rica taxon. We report here the complete mitochondrial genome of the Costa Rica taxon and its genetic differentiation from the Brazil taxon. The whole mitochondrial genome was obtained from next-generation sequencing of genomic DNA. It had a total length of 13,652 bp, comprising 36 genes (12 protein-coding genes-PCGs, 2 rRNA and 22 tRNA genes) and a control region (A + T rich non-coding region). It is longer than that of the Brazil taxon (13,585 bp). The larger mitogenome size of the Costa Rica taxon is due to the size of the control region as the Brazil taxon has a shorter length (265 bp) than the Costa Rica taxon (318 bp). The size of 6 PCGs and the start codon for ATP6, CYTB and NAD5 genes are different between the Costa Rica and Brazil taxa. Additionally, the two taxa differ in the stop codon of 6 PCGs. Molecular phylogeny based on 12 PCGs was concordant with two rRNA, 22 tRNA and 36 mitochondrial genes. The two taxa have a genetic distance of p = 16.2% based on 12 PCGs, p = 15.3% based on 36 mitochondrial genes, p = 13.1% based on 2 rRNA genes and p = 10.7% based on 22 tRNA genes, indicating status of sibling species. The Costa Rica and Brazil taxa of A. costaricensis are proposed to be accorded specific status as members of a species complex.

  15. Fulltext Do cryptic species exist in Hoplobatrachus rugulosus? An examination using four nuclear genes, the cyt b gene and the complete MT genome
    Yu D, Zhang J, Li P, Zheng R, Shao C
    PLoS One, 2015;10(4):e0124825.
    PMID: 25875761 DOI: 10.1371/journal.pone.0124825
    he Chinese tiger frog Hoplobatrachus rugulosus is widely distributed in southern China, Malaysia, Myanmar, Thailand, and Vietnam. It is listed in Appendix II of CITES as the only Class II nationally-protected frog in China. The bred tiger frog known as the Thailand tiger frog, is also identified as H. rugulosus. Our analysis of the Cyt b gene showed high genetic divergence (13.8%) between wild and bred samples of tiger frog. Unexpected genetic divergence of the complete mt genome (14.0%) was also observed between wild and bred samples of tiger frog. Yet, the nuclear genes (NCX1, Rag1, Rhod, Tyr) showed little divergence between them. Despite this and their very similar morphology, the features of the mitochondrial genome including genetic divergence of other genes, different three-dimensional structures of ND5 proteins, and gene rearrangements indicate that H. rugulosus may be a cryptic species complex. Using Bayesian inference, maximum likelihood, and maximum parsimony analyses, Hoplobatrachus was resolved as a sister clade to Euphlyctis, and H. rugulosus (BT) as a sister clade to H. rugulosus (WT). We suggest that we should prevent Thailand tiger frogs (bred type) from escaping into wild environments lest they produce hybrids with Chinese tiger frogs (wild type).

    PMID: 25471442 DOI: 10.3109/19401736.2014.987237
    This is the first study to identify and determine the phylogenetics of neritids found in Malaysia. In total, twelve species from the family Neritidae were recorded. Ten species were from the genus Nerita and two species were from the genus Neritina. DNA barcodes were successfully assigned to each species. Although some of these species were previously reported in the region, three are only presently reported in this study. The dendrogram showed Nerita and Neritina strongly supported in their respective monophyletic clades. Phylogenetic positions of some species appeared unstable in the trees. This could be due to the differences in a small number of nucleotides, thus minimizing genetic variation between each specimen and species.
