Abstract

Avian Beta Defensin 2 (AvBD2) gene, which is located in chromosome 3, plays an important role in the immune system of the chicken by inhibiting the development of microorganisms such as bacteria that infect body tissues. Defensins are produced through epithelial cells immediately after tissue injury or infection, which then processes the maturation of dendritic cells to initiate an immune response in the lymph nodes. The purpose of this study was to discover the polymorphism of the AvBD2 gene in IPB-D1 chickens. PCR and direct-DNA sequencing methods were used to identify the diversity of intron 1, exon 2, and intron 2 AvDB2 genes in 47 chickens. Genotype and allele frequency, and heterozygosity calculations were carried out to obtain information of the AvBD2 gene polymorphism. A total of 10 single nucleotide polymorphisms were found in the AvBD2 gene located in intron 1 (g.4843T>A, g.4853G>A, and g.4859T>C), exon 2 (g.4881A>G, g.4889G>A, and g.5002C>T), and intron 2 (g.5075C>T, g.5111T>G, g.5116G>T, and g.5177G>T). All SNPs are polymorphic. The g.5002C>T mutation causes changes in the amino acid Ala to Val which has the potential to be a candidate for characterizing disease resistance in IPB-D1 chickens.

Abstract

The prolactin gene (PRL) is a gene that controls the incubation and egg production in laying chickens. The nature of incubation will reduce egg production and disrupt the reproductive system in local chickens. The purpose of this study was to identify the polymorphism of prolactin genes in IPB-D1 chickens using the direct sequencing method. The polymorphism of the exon 5 prolactin gene was carried out on 46 samples of IPB-D1 chicken DNA which was a collection of the Division of Animal Genetics and Breeding, Faculty of Animal Science IPB. DNA sequences as a reference for designing exon 5 primers were obtained from the National Center for Biotechnology Information (NCBI) with the GenBank access code: AF288765.2. DNA extraction was carried out using the phenol-chloroform technique. DNA amplification resulted in a PCR product with a size of 557 bp. In this study, the genotype frequency, allele frequency, heterozygosity value and Hardy-Weinberg equilibrium were calculated. The results of the study found 5 SNPs in exon 5, namely g.7823A>G, g.7835A>G, g.7886T>A, g.8052T>C, and g.8069T>C. All SNPs are polymorphic and in Hardy-Weinberg equilibrium except g.8052T>C. The g.7823A>G, g.7835A>G, g.8052T>C SNPs are synonymous mutations that do not change amino acids, while the g.7886T>A and g.8069T>C SNPs are non-synonymous that change amino acids. Both g.7886T>A and g.8069T>C SNPs are potential as a marker assisted selection for the characteristics of egg production in IPB-D1 chickens.

Abstract

The Thy1 gene is a member of the immunoglobulin superfamily, which is found in many different animals. This gene encodes a Thy1 protein (CD90) which measures 25–37 kDa. Although the function of the Thy1 gene is unknown, it is thought to play a crucial role in the immunological response, particularly in the activation of T cells. The goal of this study was to find a variation in the Thy1 gene in IPB D2  chickens that might be utilized as candidates for immunoresistance genetic markers. A total of 123 samples from IPB D2 chickens consisting of 38 samples from IPB D2 G0 (basic generation) chickens and 85 samples from IPB D2 G2 (second generation) chickens were used in this study. PCR methods and direct-DNA sequencing were used in this study. Data analysis in this study consisted of genotype frequency, allele frequency, observed heterozigosity, expected heterozygosity, and Hardy-Weinberg equilibrium. The results of the study  discovered two SNPs on the intron (g.2139 CT and g.2542 AG). Four haplotypes were created by combining two SNPs. The g.2139 CTand g.2542 AG were polymorphic, but not in the Hardy-Weinberg equilibrium.
