Genetic Characterization Of Pakistani Wild Quails Using Mitochondrial Coi Gene

by Wajiha Shakil (2012-VA-817) | Dr. Ali Raza Awan | Dr. Muhammad Yasir Zahoor | Prof. Dr. Tahir Yaqub.

Material type: book Book; Literary form: not fiction Publisher: 2015Dissertation note: A latest taxonomic tool termed as DNA barcoding is being used to genetically characterize animals. DNA barcoding is helpful in determining evolutionary relationship among species. Being a small sized genome and agile enough to show rapid mutation, mtDNA has been used as a pertinent marker of molecular biodiversity. DNA barcode works as an efficient tool in food manufacturing industry, diet investigation, forensics analysis, preventing unlawful trade and felonious poaching. The aim of this study was to develop DNA barcode for genetic characterization of Pakistani wild quail. Pakistani wild quail is important due to its demand for eggs, meat production, experimental purposes and gaming as well. Japanese quail was also included in this study because this quail is excessively produced in Pakistani farms. Japanese quail is present throughout the year and is comparatively bigger in size than wild quail. It has longer lifespan; farmers can easily breed this species in farms. It is suitable in poultry due to better meat yield. COI gene (500bp) was used as a molecular marker for identification at species level. DNA was extracted from blood samples of ten wild quails (Coturnix coturnix and fifteen japanese quails (Coturnix japonica). Reported bird universal primers were used to amplify COI region from the extracted mtDNA samples using PCR. Amplicon were then sequenced by Sanger sequencing method (Sanger et al. 1977). Forward and reverse DNA Sequences were aligned with the reference sequence using nucleotide BLAST on NCBI to observe the dissimilarity among the sequences. Consensus sequences generated were used to construct their phylogenetic tree to see their evolutionary relationship with other bird species. Japanese quail which is thought to be domesticated from Japan, its Pakistani population showed close relation with sequences Summary 90 generated in Japan for this particular species. Pakistani wild quail species showed its closest linkage with C. coturnix. In conclusion, COI barcode proved as an authentic tool for species identification and phylogenetic inference of Pakistani wild and farm grown quails. Wild quail species has been characterized using partial COI gene sequences. This study has provided a specific genetic marker which can differentiate Japanese quail from wild quail at molecular level as most of the time both species are confused with each other. It can be helpful to the farmers and bird fanciers because they can select the birds of their choice correctly. This is the first study reporting DNA barcode of this Pakistani quail species. It would help researchers to study about phylogenetic and taxonomic status and also assist quail fanciers and quail farmers to unaffectedly identify their species of interest in farming. Identification of quail species is also important for conservation of biodiversity as it helps in preservation and identification of endangered species by generating their barcodes from even minimal evidence available.

Analysis Of Genetic Polymorphism In Exon 6 & 11 Of Glucosidase Beta Acid (Gba) Gene In Gaucher Diseased Patients From Punjab, Pakistan

by Aysha Arshad (2009-VA-571) | Dr. Muhammad Yasir Zahoor | Dr. Muhammad Imran | Dr. Imran Altaf.

Material type: book Book; Format: print ; Literary form: not fiction Publisher: 2015Dissertation note: Gaucher disease (GD) is amajor predominant heterogenic, inherited and metabolic lysosomal storage disorder. It is prompted by an alteration in glucosidase acid beta (GBA) gene. GBA gene encodes a 497 amino acid glucocerebrosidase enzyme. It is a lysosomal hydrolase, present in all mammalian cells membrane that carries the catalysis of complex ubiquitous sphingolipids called glucocerebrosides (GlcCer) into smaller and simpler molecules of sugar and ceramide. The human glucocereborside (GBA) gene is present in highly gene dense area on q arm of 21 chromosome and its fragment length is 7.8kb comprising of 11 exons. A pseudogene is also present in vicinity of GBA gene which shares 96% homology of sequence with functional gene. Genetic recombination and gene conversion among these two GBA genes are responsible for 10-20% GD mutations. >300 mutations of GBA have been described till 2014. GD has three different clinical forms depend on its heterogeneity. These are characterized by the age of onset and with or without the participation of CNS. In this study, 10 blood samples were collected of GD patients from repository at Molecular and Genomic Laboratory located at IBBT department, UVAS Lahore and from Children Hospital Lahore. DNA extraction was done by using organic method from blood samples. Amplification of GBA gene exons 1, 6 and 11 was performed using PCR. PCR products were sequenced using Sanger di-deoxy sequencing method. Different bioinformatics tools were applied for the sequence analysis of exon 1, 6 and 11. We found two variants of GBA gene. A deletion of CT nucleotide repeat in intron 1 was found. We also found a substitutional change of nucleotide T>A in intron 8.
