“…However, higher values were reported by Kumar et al (2006) and Vijh et al (2008b) for other Indian buffalo breeds, although the set of microsatellite loci utilized in both these studies were different from that used in the present study. The mean observed heterozygosity for Banni (0.441) and Murrah (0.464) are comparatively lower than that reported in other Indian Kathiravan et al 2008;Arora et al 2004 andKumar et al 2006) and Anatolian (Soysal et al 2005) water buffaloes. Considerable level of heterozygote deficiency was found to exist in both Banni and Murrah buffalo populations with a global deficit of 23.2%.…”

The present study was conducted to evaluate genetic diversity of Banni buffalo and its relationship/differentiation with Murrah using genotypic data on 24 heterologus bovine specific microsatellite marker loci. A total of 138 alleles were observed with a mean of 5.75 alleles/locus across two populations. The mean observed and expected heterozygosities were found to be 0.441 and 0.572 respectively in Banni buffaloes while it was 0.464 and 0.610 respectively in Murrah buffaloes. The average heterozygosity deficit was significantly positive with substantially higher values observed in Banni (22.3%) and Murrah (24%) buffalo populations. Banni buffalo population, when evaluated for mutation drift equilibrium revealed significant heterozygosity excess under IAM while no such excess was observed under SMM and TPM. The qualitative graphical test revealed a normal L-shaped distribution of allele frequencies indicating the absence of genetic bottleneck in Banni buffaloes. The mean estimates of F-statistics over all the loci were 0.376 for F(IT), 0.187 for F(ST) and 0.232 for F(IS) respectively. Analysis of molecular variance (AMOVA) revealed 18.95% of the total variation being explained by between breed differences while 14.36% of the variation explained differences between individuals within each breed. Genotype assignment test revealed distinct clustering of Banni and Murrah buffaloes. Genetic distance was estimated using three different methods, the results of which revealed considerable genetic differentiation between these two buffalo populations. The divergence time between Banni and Murrah buffaloes was estimated to be around 7286 years. The results of the present study may be helpful in decision making for conservation programs as Banni buffalo population is on decline.

“…Consequently, With the exception of BoLA-DRB3, all the nine microsatellite loci used in the present study can be considered useful for the evaluation of genetic diversity in buffalo populations. The mean PIC obtained in this study is more than that reported in other buffalo breeds (AMINAFSHAR et al, 2008;ÁNGEL-MARÍN et al, 2010;KATHIRAVAN et al, 2009).…”

“…The microsatellite markers used in this study were chosen according to published studies on microsatellite genetic variation in water buffalo populations (BARKER et al, 1997;KATHIRAVAN et al, 2009;MOIOLI et al, 2001;NAVANI et al, 2002;ZHANG et al, 2007). A total of ten heterologous microsatellite loci were chosen for the study to be polymorphic in buffalo.…”

Indigenous buffalo breeds represent a unique genetic resource, and understanding their variability, population structure and breeding units is important for their sustainable conservation. In the present study the genetic structure of Iranian buffalo populations was analyzed using ten microsatellite markers. Two hundred hair samples were collected and DNA was extracted using modified salting out method. After Polymerase Chain Reaction (PCR), the PCR products were electrophoresed using 9% polyacrylamide gel. Fifty-nine alleles were observed for all the loci. The average number of alleles was 5.90 and the effective average number of alleles was 4.86. The high level of mean heterozygosity index between three populations indicate that the genetic diversity is high in within and between populations. The mean of polymorphism information content (PIC) value for all loci was 0.70. The FST value for the total loci was 0.01, indicating a very low level of genetic structure among populations. The genetic structure AMOVA analysis showed that about 3% of the total genetic variation was explained by population differences and 97 percent was corresponded to differences among individuals. The obtained results at the present study indicated that characterization of genetic diversity by employing molecular tools is a prerequisite in developing strategies for conservation and utilization of buffalo genetic resources.

“…2006). Marathwada buffaloes in Central India represent a very ancient indigenous type and are reared in low external input system mainly because of their low maintenance cost, feed conversion efficiency, moderate production and ability to thrive under harsh climatic conditions (Kathiravan et al. 2009).…”

We report the genetic structure and evolutionary relationship of the endangered Toda buffalo of Nilgiris in South India with Kanarese and two other riverine buffalo breeds. The upgma phylogeny drawn using Nei's distance grouped South Kanara and Toda buffaloes at a single node while Marathwada and Murrah together formed a separate node. Principal component analysis was performed with pairwise interindividual chord distances which revealed clustering of Murrah and Marathwada buffaloes distinctly, while individuals of Toda and South Kanara breeds completely intermingled with each other. Furthermore, there were highly significant group variances (p < 0.01) when the breeds were grouped based on phylogeny, thus revealing the existence of cryptic genetic structure within these buffalo breeds. To know the evolutionary relationship among these breeds, 537-bp D-loop region of mitochondrial DNA was analysed. The phylogenetic analysis of mtDNA haplotypes following NJ algorithm with Chinese swamp buffalo as outgroup revealed a major cluster that included haplotypes from all the four investigated breeds and two minor clusters formed by South Kanara and Toda haplotypes. Reduced median network analysis revealed haplotypes of South Kanara and Toda to be quite distinct from the commonly found haplotypes indicating that these might have been ancestral to all the present-day haplotypes. Few mutations in two of the haplotypes of South Kanara buffalo were found to have contributed to ancestral haplotypes of Toda buffalo suggesting the possible migration of buffaloes from Kanarese region towards Nilgiris along the Western Ghats. Considering the close social, economic and cultural association of Todas with their buffaloes, the present study supports the theory of migration of Toda tribe from Kanarese/Mysore region along with their buffaloes.
