| dc.description.abstract | Gen PRLR merupakan salah satu gen yang berperan dalam pengaturan
termoregulasi serta ketahanan terhadap stres panas. Mutasi pada gen PRLR
berpengaruh besar terhadap sifat SLICK. Penelitian ini bertujuan untuk
mengidentifikasi keberadaan mutasi dan keragaman SNP ekson 11 gen PRLR pada
populasi sapi pedaging Indonesia. Sebanyak 20 sampel DNA digunakan dalam
penelitian ini, yang terdiri dari 10 sampel sapi bali dari BPTU-HPT Denpasar, 6
sampel sapi PO dari BET Cipelang, dan 4 sampel sapi limousin dari BPTU-HPT
Padang Mangatas. Keragaman gen PRLR diidentifikasi menggunakan sekuensing
DNA. Hasil sekuensing menunjukkan tidak adanya variasi genetik pada sapi bali,
sedangkan SNP pada lokus c.210 G>A dan c.236 C>A teridentifikasi pada sapi PO
dan limousin sebagai synonymous mutation. Analisis keragaman genetik pada
ketiga bangsa sapi menunjukkan tingkat keragaman yang rendah, dengan frekuensi
genotipe yang masih berada dalam keseimbangan Hardy-Weinberg. Oleh karena
itu, pemanfaatan SNP gen PRLR sebagai marka genetik sifat ketahanan panas masih
memerlukan penelitian lanjutan. | |
| dc.description.abstract | The PRLR gene is one of the genes involved in thermoregulation and
resistance to heat stress. Mutations in the PRLR gene have a significant influence
on the SLICK trait. This study aimed to identify the presence of mutations and the
genetic diversity of SNP in exon 11 of the PRLR gene in Indonesian beef cattle
populations. A total of 20 DNA samples were used in this study, consisting of 10
bali cattle samples from BPTU-HPT Denpasar, 6 Peranakan Ongole (PO) cattle
samples from BET Cipelang, and 4 limousin cattle samples from BPTU-HPT
Padang Mangatas. Genetic variation in the PRLR gene was identified using DNA
sequencing. The sequencing results showed no genetic variation in bali cattle,
whereas SNP at loci c.210 G>A and c.236 C>A were identified in PO and Limousin
cattle as synonymous mutations. Genetic diversity analysis of three cattle breeds
revealed low levels of genetic diversity, with genotype frequencies remaining in
Hardy-Weinberg equilibrium. Therefore, further studies were needed to evaluate
the potential use of PRLR gene SNP as genetic markers for heat tolerance. | |
