Sažetak

The Aquaporin 7 (AQP7) gene, a member of the aqua-glyceroporins, was characterised using Polymerase Chain Reaction-Single Strand Conformation Polymorphism (PCR-SSCP) analysis, in order to investigate the association of genetic variants of the AQP7 gene with semen quality in Murrah bulls. In this study, genomic DNA was extracted from the blood of Murrah bulls (n = 69) using the high salt method. Sequence data were analyzed using Bio Edit software (version 7.0.5) for detecting single nucleotide polymorphisms (SNPs). Statistical analysis was carried out using repeated GLM procedure measures (SAS 9.3). Analysis revealed 17 different SSCP variants in the AQP7 gene in Murrah buffaloes. Three unique SSCP band patterns were observed in exons 1 and 4. Exons 5, 7 and 8 showed five, four and two unique SSCP band patterns, respectively. Sequence analysis revealed a total of 20 SNPs (8 in exonic and 12 in intronic region). PCR-SSCP variants of exon 5 were significantly associated (P<0.01) with sperm concentration. SSCP variants of exons 5 and 8 were associated (P<0.05) with sperm viability and post thaw motility (PTM), respectively. The study revealed a high degree of genetic variability in the AQP7 gene in Murrah bulls. The SSCP variants observed are associated with semen parameters which suggests the possibility of using the AQP7 gene as a candidate gene for identification of markers for semen quality traits in buffaloes.
