Abstract

Abstract: Genetic factor plays a very important role in determining of cattle performance. A gene which is reported to be controlling cattle growth and body size is pleomorphic adenoma gene 1 ( PLAG1 ). Therefore, the goal of this study was to identify PLAG1 polymorphisms in PO cattle population. A total of 43 unproductive PO cows from the slaughterhouse at Kebumen were used in this study. Blood samples were collected individually when the cattle were slaughtered. Furthermore, DNA genome was harvested from blood samples and used as DNA template for polymerase chain reaction (PCR) targeting g.48308 C>T, g.32212 (19 bp indel) and g.45233 T>C polymorphisms. g.48308 C>T and g.45233 T>C SNPs were genotyped using PCR-restriction fragment length polymorphism (PCR-RFLP) technique and a 19 bp indel of PLAG1 was directly genotyped by observing PCR products. Both allele and genotype frequencies were calculated to test Hardy-Weinberg equilibrium (HWE) status. The results showed that g.48308 C>T SNP and 19 bp indel varied. Three genotypes of the g.48308 C>T SNP namely CC, CT and TT were found in this study and two genotypes (DD and DI) of 19 bp indel were also identified. Moreover, heterozygous CT genotype frequency of g.48308 C>T SNP was 0.51 and T allele frequency was 0.60. In term of 19 bp indel, DD genotype frequency was 0.88 and D allele frequency was 0.94. In conclusion, two polymorphisms of the PLAG1 were identified in PO cattle population.
