In this study, to analyze the mtDNA D-loop region and the origin of the maternal lineages of 16 different donkey populations, and to assess the domestication of Turkish indigenous donkeys in seven geographical regions, we investigated the DNA sequences of the D-loop region of 315 indigenous donkeys from Turkey. A total of 54 haplotypes, resulting from 35 polymorphic regions (27 parsimoniously informative and 6 singleton sites), were defined. Twenty-eight of these haplotypes are unique (51.85%), and 26 are shared among different Turkish indigenous donkey populations. The most frequent haplotype was Hap 1 (45.71%), followed by two haplotypes (Hap 4, 15.55% and Hap 7, 5.39%). The breed genetic diversity, evaluated by the haplotype diversity (HD) and nucleotide diversity (πD), for the Turkish donkey populations ranged from 0.533 ± 0.180 (Tekirdağ–Malkara, MAL) to 0.933 ± 0.122 (Aydin, AYD), and from 0.01196 ± 0.0026 (Antalya, ANT) to 0.02101 ± 0.0041 (Aydin, AYD), respectively. We observed moderate-to-high levels of haplotype diversity and moderate nucleotide diversity, indicating plentiful genetic diversity in all of the Turkish indigenous donkey populations. Phylogenetic analysis (NJT) and median-joining network analysis established that all haplotypes were distinctly grouped into two major haplogroups. The results of AMOVA analyses, based on geographic structuring of Turkish native donkey populations, highlighted that the majority of the observed variance is due to differences among samples within populations. The observed differences between groups were found to be statistically significant. Comparison among Turkish indigenous donkey mtDNA D-loop regions and haplotypes, and different countries’ donkey breeds and wild asses, identified two clades and which is named Somali (Clade IV) and Nubian (Clade V) lineages. The results can be used to understand the origin of Turkish donkey populations clearly, and to resolve the phylogenetic relationship among all of the different regions.

Kalang (KBuf), Krayan (KrBuf), and Thale Noi buffaloes (TBuf) are swamp buffalo genetic resources in Indonesia and Thailand. The maternally inherited mitochondrial DNA (mtDNA), particularly D-loop region is an important material for phylogenetic inference and analyzing genetic diversity. Therefore, the objectives of the present study were to evaluate genetic diversity and to reconstruct the phylogenetic tree within buffalo breeds in Kalimantan, Indonesia, and Phatthalung, Thailand using mtDNA D-loop sequences. A total of one hundred forty buffaloes (70 males and 70 females) were observed including 40 buffaloes from North (NK), 40 from East (EK), and 40 from South Kalimantan (SK) provinces Indonesia and 20 from Phatthalung (PT) province, Thailand. DNA samples were isolated from buffalo tail hairs. DNA sequences were manually assembled using BioEdit program with consideration of gaps and ambiguous sequences. The phylogenetic tree of buffalo was generated by PHYLIP software. The observed variables included haplotype diversity, genetic distance, and genetic tree. The 956 bp of amplified mtDNA D-loop fragment presented a total of 24 haplotypes with several mutations that included transitions (293), transversions (60), deletions (15), and insertions (20). The neighbor-joining tree using the Kimura 2 parameter model demonstrated two local buffalo clusters among buffalo from Kalimantan and Thailand with four buffalo relationship patterns observed from buffaloes in Kalimantan Island (KBuf and KrBuf), Indonesia. The Results of the present study demonstrated that the buffaloes sequence analysis revealed relatively high diversity and is a good basis to perform selection and modern buffalo breeding development.

Nigerian indigenous chickens possess immunity from endemic diseases and have a better survival rate than commercial hybrid strains under local production conditions. FUNAAB Alpha chicken was developed by improving Nigerian indigenous chickens through crossbreeding and selection. This study compared the mitochondrial d-loop of FUNAAB Alpha and Nigerian indigenous chickens to check likely genetic erosion and loss of diversity in development of FUNAAB Alpha breed. Blood samples were collected from Nigerian indigenous (n=23) and FUNAAB Alpha (n=20) chickens sampled from farms and houses in Ogun state, Nigeria. The Hypervariable 1 (HV1) of the mitochondrial d-loop region was amplified and sequenced. Single nucleotide polymorphisms present in HV1 of chickens were identified using Clustal W. Genetic diversity of the region was determined using DnaSp v5 while selective forces acting on the chickens were predicted using HyPhy software implemented inside MEGA 6 software. Phylogenetic relationship among FUNAAB Alpha, Nigerian indigenous and other chicken breeds was determined using MEGA 6 software. Five polymorphisms were identified in FUNAAB Alpha chickens while twelve were identified in Nigerian indigenous chickens. All the polymorphisms identified in FUNAAB Alpha chickens were also observed in Nigerian indigenous chickens while seven polymorphisms were unique to Nigerian indigenous chickens. Higher diversity indices were observed in Nigerian indigenous chickens (number of haplotype: 4; haplotype diversity: 0.743±0.012; nucleotide diversity: 0.014±0.0013 and average number of nucleotide differences: 4.332) compared with FUNAAB Alpha chickens (number of haplotype: 2; haplotype diversity: 0.485±0.001; nucleotide diversity: 0.008±0.0001 and average number of nucleotide differences: 2.424). Positive selective forces were acting on FUNAAB Alpha chickens while negative selective forces were acting on Nigerian indigenous chickens. Phylogenetic analysis revealed that FUNAAB Alpha chickens clustered with Nigerian indigenous and South American chickens. It can be concluded that there was likely genetic erosion and loss of diversity in development of FUNAAB Alpha breed. Breeding programmes aimed at improvement of genetic diversity and reduction of genetic erosion should be applied in subsequent improvement of FUNAAB Alpha chickens.

Pelicans (Pelecanus conspicillatus) is one of the wild species that have a widely distribution. This bird has been successfully bred in Ragunan Zoo, Jakarta. The indicator of inbreeding in the captive population is shown by the decrease of nucleotide diversity and number of haplotypes. The result of genetic diversity analysis using D-loop fragment sequences showed low genetic diversity with nucleotide diversity (p) = 0.00064 ± 0.00010 and haplotype diversity (Hd) = 0.532 ± 0.061 in Pelecanus conspicillatus populations in the Ragunan Zoo. However, negative Fu's Fs value (-3,246) indicates population expansion. We found that there were seven haplotypes in bird populations in the captivity: haplotype 1, 2 and 3 consist of 43 individuals (65.15%), five individuals (7.57%), and 14 individuals (21.21%), respectively. For each haplotype 4, 5, 6 and 7 is only represented by one individual of Pelecanus conspicillatus (1.51%). The sex ratio of males to females is 1: 8.86 with four males identified as haplotype 1, and one male on haplotypes 3, 5 and 7, respectively. Genetic diversity data of the population is an important way for designing long-term plans and goals in efforts to maintain genetic diversity of the Pelecanus conspicillatus population in captivity.

Abstract. Karuppannan KV, Aifat NR, Mohamed KA,  Ahmad-Tahir NFD,  Nordin FM, Yaakop S, Maldonado JE, Md-Zain BM. 2019. Genetic variations among selected wild Asian elephant populations in Peninsular Malaysia based on mitochondrial D-loop region DNA sequences. Biodiversitas 20: 2494-2502. Asian elephant (Elephas maximus) is an important large mammal in Peninsular Malaysia and is completely protected by the Wildlife Conservation Act 2010 (Act 716). The conservation of this species requires strong information-based research, such as genetic evaluations. The aim of this study was to compare mitochondrial control region variation among selected elephants from the Taman Negara National Parks (TNNP) population with other selected populations in Peninsular Malaysia. DNA materials were extracted from fecal samples and amplified using partial mitochondrial D-loop region. Total 13 haplotypes with haplotype diversity (Hd) of 0.7524 were observed. A total of 34 base pair (bp) segregation sites were formed in 547 bp sequences. Both phylogenetic trees showed that a few individual elephants from the TNNP formed a clade together with individuals from other populations. The remaining individual elephants from TNNP formed a monophyletic clade supported by a high bootstrap value. Low genetic distance was detected among the tested populations, which proved that both individuals from the TNNP and other selected populations have similar genetic patterns. High gene flow among tested populations would impact on fitness and long-term resilience of the populations. This highly significant outcome provides strong baseline data for Department of Wildlife and National Parks (DWNP) in monitoring elephant populations in order to reduce number of human-elephant conflicts which indirectly minimize translocating conflict elephants to TNNP.

Abstract Perna viridis is a mussel commonly distributed along the Asian Indo-Pacific coasts. It is one of the main cultured species of that region. Previous studies focused mostly on the native populations within single countries; with the present study we analyzed the genetic diversity of P. viridis in a large study area, spanning from Oman to southern China. Three molecular markers were used, namely portions of the nuclear ITS region, and the mitochondrial COI gene and D-Loop region. The nuclear marker showed moderate levels of genetic diversity (haplotype diversity h = 0.543 to 0.897) and nucleotide diversity π = 0.0022 to 0.0064); whereas mitochondrial markers exhibited higher levels of genetic variability (h = 0.858 to 0.964 and π = 0.0012 to 0.0079). The estimates of inter-sample genetic divergence (FST) and the analysis of molecular variance highlighted that the Thai population is genetically divergent from the others. Our results showed the genetic variation of P. viridis at the rim of South China Sea and obtained the genetic basic information of P. viridis.

Clarias magur, popularly known as magur, is one of the economically important catfish species having high aquaculture potential in India due to its efficient food conversion, taste, and nutritional benefits. Due to habitat degradation, over exploitation, lack of resources, indiscriminate use of agricultural pesticides and introduction of competitor exotic species, the wild populations are dwindling day by day. According to IUCN, it is listed as endangered species. In the present study, the population genetic structure of 206 magur samples collected from seven different geographical regions was examined using partial mitochondrial D-loop (control region) sequence variation. In total of 17 haplotypes were observed with high number of private alleles, number of haplotypes ranged from 2 to 6 and maximum number of haplotypes was observed in UP population. Haplotype diversity and nucleotide diversity ranged from 0.06897 to 0.76322 and 0.00019 to 0.00208, respectively. Pairwise FST values ranged from 0.01383 to 0.62069 and highest genetic differentiation was observed between AP and AS population. Low genetic diversity and significant population genetic differentiation was observed in the present study. The information generated in the present investigation would facilitate formulating appropriate strategy for management, conservation, and genetic improvement program of this commercially important aquaculture species.

Abstract Horses have played a significant role in the development of human society. As an important domestic animal, horses have been used for transport, labor, food and recreation. It is widely accepted that the horse was probably first domesticated on the Eurasian steppes from Ukraine to Turkestan between the fifth and fourth millennium BC, and the earliest domesticated horses subsequently spread out from their original range. However, we currently have little genetic evidence to demonstrate whether Korean domestic horse breeds originated in Korea or if it came into the area via an ancient migration route. In the present study, to obtain more knowledge of the origin and genetic diversity of Korean domestic horses, we analyzed seventeen 247-bp mitochondrial DNA (mtDNA) D-loop sequences of ancient horse bones excavated from seven archaeological sites located in the southern Korean Peninsula and Mongolia, aged between the fifth century B.C and nineteenth century A.D. The seventeen ancient horses revealed 9 variable positions when compared with the reference sequence (GenBank X79547). All the substitutions were transitions, and defined a total of 11 unique haplotypes with the haplotype diversity value of 0.9118±0.056. Among the 11 haplotypes, 3 haplotypes were detected more than once and were thus shared by individuals from the same or close archaeological sites. The largest haplotype consisted of 5 individuals, with another two haplotypes containing 2 individuals respectively, and eight haplotypes were singletons. The data indicate an abundant genetic diversity of the Korean ancient horses, and also suggest that the origin of Korean domestic horses is complex, and several maternal lines were introduced into the gene pool of Korean horses after their initial domestication.

This study assessed and compared the genetic diversity of Nemipterus randalli across its native and non-native regions analysing the mitochondrial DNA D-loop region. Including all the geographical population samples, 68 haplotypes were observed with an average haplotype diversity value of 0.92±0.04. Relatively, a smaller number of haplotypes was observed in the invasive range of the Mediterranean Sea. All other native geographical samples showed high haplotype and nucleotide diversity values. A significant high genetic differentiation value was observed between the native population samples of India and the invasive samples of the Mediterranean Sea. In the median-joining network tree, N. randalli from the Mediterranean Sea and the Red Sea formed a single haplogroup while other samples from India are clustered into two haplogroups.
