Association of CAST gene polymorphism with carcass value and meat quality in two synthetic lines of sheep

Abstract. Jakaria, Ulum MF, Lestari D, Akwila S, Sihite DEWT, Priyanto R, Muladno, Sumantri C. 2020. Investigating new SNPs of CAST, CAPN and SCD genes in 5’UTR of Bali cattle. Biodiversitas 21: 2971-2976. The present investigation aims to explore specific SNPs of Bali cattle, focusing mainly on CAST, CAPN, and SCD genes in 5'UTR. DNA of Bali cattle (25 individuals) from Breeding Centre of Bali cattle in Bali Province, Indonesia, were extracted according to the protocol of GenAID. Amplification of the CAST, CAPN, and SCD genes were designed using the Primer3 program based on reference sequences (access numbers AH014526.2, AH009246.3, and AY241932). Furthermore, the PCR product was sequenced through forward primer sequencing. The data sequence results were analyzed using the Bioedit, MEGA7, Popgen 3.2, and DnaSP6 V6 programs. The results showed that SNPs were detected at g.921C>T and g.922T>G in 5'UTR for the CAST gene between the reference of GenBank AH014526.2 and Bali cattle, but it was monomorphic within the population. The high polymorphism of SNPs was found in g.232G>T for the CAPN gene and g.134A>del for the SCD gene. However, the SNP g.246C>del SCD gene was detected as monomorphic in this region. Moreover, this result shows that low nucleotide diversities (Pi) for CAST, CAPN, and SCD genes in 5'UTR of Bali cattle were 0.00422, 0.00632, and 0.00449, respectively. This finding was important for developing marker-assisted selection (MAS) to improve the meat quality of Bali cattle.

Cast Gene

At present, modern technologies involving the use of DNA markers, which are widely used in national breeding programs in a number of countries with developed animal husbandry are of considerable interest and have a signifi cant infl uence on improving productivity traits. A signifi cant number of genes associated with meat productivity and meat quality have been identifi ed. In sheep breeding such research has been developed only recently. Due to the growing interest in the production of young mutton and lamb, priority is given to the study of genes that control meat productivity. However, the most popular are genetic markers that are interconnected with candidate genes, whose protein products play a signifi cant role in the formation or regulation of physiological and biochemical processes. Alleles of the Growth Hormone (GH) gene and Calpastatin (CAST) gene are considered as potential markers of sheep meat productivity. In this regard, the purpose of this work was to study the polymorphism of GH and CAST genes in crossbred wool-and-meat producing sheep (1/2 Poll Dorset × 1/2 North Caucasian wool-and-meat producing breed) bred in the Stavropol Territory. The analysis of Somatotropin and Calpastatin gene polymorphism was performed by PCR-PDRF. When studying GH gene polymorphism, the genotypes AA, AB and BB have been found, the frequency of occurrence of which was 29,7; 42,8 and 27,5 %, respectively. Allele A prevailed in the studied animals – 0,786, allele B was – 0,214. The CAST gene was represented by two genotypes MM and MN (the NN genotype was absent in the animals of this group) with a frequency of 87,9 and 12,1 %, respectively. The frequency of the M allele was high at 0,94, while the n allele was low at 0,06. The results obtained during the researches indicate the establishment of a variety of allelic variants of Somatotropin and Calpastatin genes in wool-and-meat producing sheep. Further research will be aimed at studying the association of identifi ed polymorphisms with economically useful traits.
