Abstract We presented the powerful techniques for species identification using the short amplicon of mitochondrial cytochrome b gene sequence. Two faecal samples and one single hair sample of the Asian tapir were tested using the new cytochrome b primers. The results showed a high sequence similarity with the mainland Asian tapir group. The comparative sequence analysis of the reserved wild mammals in Thailand and the other endangered mammal species from Southeast Asia comprehensibly verified the potential of our novel primers. The forward and reverse primers were 94.2 and 93.2%, respectively, by the average value of the sequence identity among 77 species sequences, and the overall mean distance was 35.9%. This development technique could provide rapid, simple, and reliable tools for species confirmation. Especially, it could recognize the problematic biological specimens contained less DNA material from illegal products and assist with wildlife crime investigation of threatened species and related forensic casework.

Abstract The mitochondrially encoded NADH:ubiquinone oxidoreductase core subunit 1 (MT-ND1) gene is a subunit of the respiratory chain complex I and involved in the first step of the electron transport chain of oxidative phosphorylation (OXPHOS). To understand the pattern of compositional properties, codon usage and expression level of mitochondrial ND1 genes in pisces, aves, and mammals, we used bioinformatic approaches as no work was reported earlier. In this study, a perl script was used for calculating nucleotide contents and different codon usage bias parameters. The codon usage bias of MT-ND1 was low but the expression level was high as revealed from high ENC and CAI value. Correspondence analysis (COA) suggests that the pattern of codon usage for MT-ND1 gene is not same across species and that compositional constraint played an important role in codon usage pattern of this gene among pisces, aves, and mammals. From the regression equation of GC12 on GC3, it can be inferred that the natural selection might have played a dominant role while mutation pressure played a minor role in influencing the codon usage patterns. Further, ND1 gene has a discrepancy with cytochrome B (CYB) gene in preference of codons as evident from COA. The codon usage bias was low. It is influenced by nucleotide composition, natural selection, mutation pressure, length (number) of amino acids, and relative dinucleotide composition. This study helps in understanding the molecular biology, genetics, evolution of MT-ND1 gene, and also for designing a synthetic gene.

Abstract Seahorse documented in Chinese pharmacopeia possess important medicinal efficacy and are used as an ingredient in traditional Chinese medicines. The growing international trade threatens the species. DNA barcoding holds a great application potentiality in wildlife conservation and might prevent the illegal trade of threatened species. The COI gene was used to identify seahorse, and nine Hippocampus species were found in the three large traditional Chinese medicines markets of China. All inter-specific genetic variations were larger than 2%. Mean genetic distances between species were 17-fold larger than those within the species. Phylogenetic tree showed that each species clustered in the appropriate branch. All results demonstrated that COI-based barcoding technique could be used to identify seahorse species and played a major role in monitoring the seahorse trade.

Abstract The known mosquito mitogenomes, containing a total of 34 species, which belong to five genera, were collected from GenBank, and the practicality and effectiveness of the variation in the complete mitochondrial DNA genome and portions of mitochondrial COI gene were assessed to reconstruct the phylogeny of mosquitoes. Phylogenetic trees were reconstructed on the basis of parsimony, maximum likelihood, and Bayesian (BI) methods. It is concluded that: (1) Both mitogenomes and COI gene support the monophly of following taxa: Subgenus Nyssorhynchus, Subgenus Cellia, Anopheles albitarsis complex, Anopheles gambiae complex, and Anopheles punctulatus group; (2) Genus Aedes is not monophyletic relative to Ochlerotatus vigilax; (3) The mitogenome results indicate a close relationship between Anopheles epiroticus and Anopheles gambiae complex, Anopheles dirus complex and Anopheles punctulatus group, respectively; (4) The Bayesian posterior probability (BPP) within phylogenetic tree reconstructed by mitogenomes is higher than COI tree. The results show that phylogenetic relationships reconstructed using the mitogenomes were more similar to those based on morphological data.

Abstract Absidia glauca and Parasitella parasitica constitute a versatile experimental system for studying horizontal gene transfer between a mucoralean host and its fusion parasite. The A. glauca chondriome has a length of approximately 63 kb and a GC content of 28%. The chondriome of P. parasitica is larger, 83 kb, and contains 31% GC base pairs. These mtDNAs contain the standard fungal mitochondrial gene set, small and large subunit rRNAs, plus ribonuclease P RNA. Comparing zygomycete chondriomes reveals an unusually high number of homing endonuclease genes in P. parasitica, substantiating the mobility of intron elements independent of host-parasite interactions.

Abstract Toxocara cati (cat roundworm) is a common parasitic nematode that infects humans and other hosts, causing toxocariasis. Although its significance as a pathogen, the epidemiology, genetics and biology of T. cati remain poorly understand in China. In the present study, genetic variation in mitochondrial (mt) cytochrome c oxidase subunit 1 (cox1) gene and internal transcribed spacer (ITS) of rDNA region among T. cati in Guangdong province, subtropical China was examined. A portion of the cox1 (pcox1) and the complete ITS (ITS1 + 5.8S rDNA + ITS2) were amplified separately from individual worms by polymerase chain reaction (PCR) and amplicons were then subjected to sequencing from both directions. The length of the sequences of pcox1, ITS-1, and ITS-2 were 308 bp, 462 bp, and 335 bp, respectively. The intra-specific sequence variations within T. cati were 0–3.6% for pcox1, 0–2.4% for ITS-1, and 0–2.7% for ITS-2. However, the inter-specific sequence differences were significantly higher, being 8.6%, 10.7%, and 11.3% for pcox1, ITS-1, and ITS-2, respectively. Phylogenetic analyses based on the pcox1 sequences indicated that all the isolates in Guangdong province were in genus Toxocara, which confirmed that these parasites represent T. cati. The molecular approach employed provides a powerful tool for elucidating the epidemiology, genetics, and biology of zoonotic T. cati in China and elsewhere.

Abstract The current understanding of the genetic diversity of the phytopathogenic fungus Ustilago maydis is limited. To determine the genetic diversity and structure of U. maydis, 48 fungal isolates were analyzed using mitochondrial simple sequence repeats (SSRs). Tumours (corn smut or ‘huitlacoche’) were collected from different Mexican states with diverse environmental conditions. Using bioinformatic tools, five microsatellites were identified within intergenic regions of the U. maydis mitochondrial genome. SSRMUM4 was the most polymorphic marker. The most common repeats were hexanucleotides. A total of 12 allelic variants were identified, with a mean of 2.4 alleles per locus. An estimate of the genetic diversity using analysis of molecular variance (AMOVA) revealed that the highest variance component is within states (84%), with moderate genetic differentiation between states (16%) (FST = 0.158). A dendrogram generated using the unweighted paired-grouping method with arithmetic averages (UPGMA) and the Bayesian analysis of population structure grouped the U. maydis isolates into two subgroups (K = 2) based on their shared SSRs.

Abstract The spiny-tailed lizard of the genus Darevskia have a series of taxonomic revisions, but still their phylogenetic relationships remain uncertain. In the present study, we have assessed taxonomic relationships among Darevskia bithynica and Darevskia rudis populations through estimation of phylogenetic relationships among 96 specimens using microsatellite DNA (Du215, Du281, Du323 and Du418 loci) and 53 specimens using mtDNA (16S rRNA and cytb) from main populations in Turkey. Although D. b. bithynica and D. r. mirabilis were separated based on the PCoA analysis at low level from other D. rudis and D. bithynica populations, the distance values of Nei's genetic distance, Nei's unbiased genetic distance, Fst and Linear Fst were not high among taxa in microsatellite DNA. On the other hand, our phylogenetic analyses (NJ, ML, MP and BI) did not separate D. rudis and D. bithynica populations. Finally, most of the topologically identical trees of phylogenetic analyses and microsatellite results showed that the extant populations of D. rudis and D. bithynica were found to be polytomy. Based on our molecular phylogenetic study, D. rudis complex is still ongoing revisions.

Abstract The Hangul (Cervus elaphus hanglu) is a “Least Concern” deer species, and it is the only survivor of the Red Deer group in the Indian subcontinent. The phylogenetic status of the Hangul relative to the other members of the family Cervidae is not known because sequence data are not available in public databases. Therefore, this study was carried out to determine the phylogenetic status and delineate the genetic boundaries of the Hangul with respect to the other Red Deer subspecies on the basis of cytochrome b gene sequence data (ca 421 bp). There are three major monophyletic groups of the Red Deer in the phylogenetic tree, which are referred to as the western (Hap-01 to Hap-10), eastern (Hap-11 to Hap-20) and tarim (Hap-21 to Hap-25) groups. The overall haplotype diversity and per-site nucleotide diversity were 0.9771 (±0.0523) and 0.0388 (±0.00261), respectively. In the phylogenetic tree, the Hangul clustered with the tarim group (Yarkand and Bactrian Red Deer) with a strong bootstrap support (92%) and was found to be genetically closer to the Bactrian Red Deer than to the Yarkand Red Deer. Our molecular analysis supported the idea that the Hangul diverged from the Bactrian Red Deer and migrated to India from Tajikistan approximately 1.2 MYA.
鹿(Cervus elaphus hanglu)是印度次大陆马鹿群中唯一幸存的“最不受关注”的鹿种。由于公共数据库中没有序列数据，因此尚不清楚韩国人与鹿科其他成员的系统发育状况。因此，本研究基于细胞色素b基因序列数据(约421 bp)，确定了汉鹿与其他马鹿亚种的系统发育状况，并划定了遗传边界。马鹿在系统发育树上有三个主要的单系群，即西部(Hap-01 ~ Hap-10)、东部(Hap-11 ~ Hap-20)和塔里木(Hap-21 ~ Hap-25)群。总单倍型多样性和单位点核苷酸多样性分别为0.9771(±0.0523)和0.0388(±0.00261)。在系统发育树中，汉族人与塔里木族(Yarkand and Bactrian Red Deer)聚集在一起，具有很强的自举支持(92%)，并且在遗传上更接近于Bactrian Red Deer而不是Yarkand Red Deer。我们的分子分析支持了韩国人从大夏马鹿(Bactrian Red Deer)分化出来，并在大约1.2 MYA从塔吉克斯坦迁移到印度的观点。

The overall haplotype diversity and per-site nucleotide diversity were 0.9771 (±0.0523) and 0.0388 (±0.00261), respectively. In the phylogenetic tree, the Hangul clustered with the tarim group (Yarkand and Bactrian Red Deer) with a strong bootstrap support (92%) and was found to be genetically closer to the Bactrian Red Deer than to the Yarkand Red Deer. Our molecular analysis supported the idea that the Hangul diverged from the Bactrian Red Deer and migrated to India from Tajikistan approximately 1.2 MYA.","PeriodicalId":54298,"journal":{"name":"Mitochondrial Dna Part a","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85891748","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract In the present study, the mitochondrial DNA phylogeny of five solifuge families of Iran is presented using phylogenetic analysis of mitochondrial cytochrome c oxidase, subunit 1 (COI) sequence data. Moreover, we included available representatives from seven families from GenBank to examine the genetic distance between Old and New World taxa and test the phylogenetic relationships among more solifuge families. Phylogenetic relationships were reconstructed based on the two most probabilistic methods, Maximum Likelihood (ML) and Bayesian inference (BI) approaches. Resulting topologies demonstrated the monophyly of the families Daesiidae, Eremobatidae, Galeodidae, Karschiidae and Rhagodidae, whereas the monophyly of the families Ammotrechidae and Gylippidae was not supported. Also, within the family Eremobatidae, the subfamilies Eremobatinae and Therobatinae and the genus Hemerotrecha were paraphyletic or polyphyletic. According to the resulted topologies, the taxonomic placements of Trichotoma michaelseni (Gylippidae) and Nothopuga sp. 1 (Ammotrechidae) are still remain under question and their revision might be appropriate. According to the results of this study, within the family Galeodidae, the validity of the genus Galeodopsis is supported, while the validity of the genus Paragaleodes still remains uncertain. Moreover, our results revealed that the species Galeodes bacillatus, and Rhagodes melanochaetus are junior synonyms of G. caspius, and R. eylandti, respectively.
