1. Dna Fingerprinting Of Pakistani Buffalo Breeds (Nili-Ravi, Kundi) Using Microsatellite And Cytochrome B Gene

by Rashid Saif | Prof.Dr.Masroor Elahi Babar | Mr. Asif | Prof. Dr. Abu Saeed Hashmi.

Material type: book Book; Format: print Publisher: 2010Dissertation note: Customarily, classification of breed was based on phenotypic traits. In some cases, recent genetic studies have found differences in the structure proposed. In buffalo ,one has to bear in mind that morphological changes were not the result of adaptation to the environment, but have a social significance thus may not be indicative of the genetic relationship. In recent years microsatellites have proved to be very useful for the determination of genetic relationship among population. Comparative studies beiween microsatellite and protein markers have highlighted the advantages of the former. The water buffalo (Bubalus bubalis) holds tremendous potential in livestock sector in many Asian countries, particularly in Pakistan but the genetic data of different buffalo breeds like Nili-Ravi and Kundi is lacking, which need to be established for their genetic identification. Blood samples of unrelated true representative of both breeds (Nili-Ravi and Kundi) were collected from different government livestock farms in Punjab and Sindh respectively. DNA was extracted by inorganic method and amplification of the mitochondrial Cytb gene and microsatellite was done with especially designed primers in Molecular Biology and Genomics Laboratory at Institute of Biochemistry and Biotechnology, University of Veterinary and Animal Sciences, Lahore. Cytochrome b gene markers have been proved as an efficient and powerful tool for breed characterization and species identification of buffaloes. Several panels of microsatellite markers have also been reported for this purpose. In this study, a panel of nine microsatellite markers has highly Polymorphism Information Content (PlC) were selected, Specific primers were designed for these microsatellite and Cytb gene partial amplification using primer3 software. Then primers were optimized for successful amplification with minimum reagent concentration. PCRs were performed for amplification of these microsatellite and Cytb markers on each sample, Genotyping and sequencing was conducted on all amplicons to find out the different SNP to design haplotypes with the help of bioinformatics software e.g. Blast 2sequence and Chrornas Lite, Further statistical analysis was done by the help of some other software e.g. Popgene version 1.31, Power Stat., Genetic diversity, Allele frequencies, observed and expected homozygosity and heterozygosity, Hardy Weinberg equilibrium, F-Statistics and Gene Flow for all Loci, population's dendogram, Nei's genetic identity and genetic distance! diversity was calculated. The results obtained from this study can contribute to the establishment of routine DNA typing services, beneficial for the buffalo industry as well as in animal forensics for litigation and expedite the police investigation services in Pakistan, which will also be useful for breed characterization and phylogenetic study of aforementioned breeds of buffalo.
