Comparison Of Heat Shock Protein Gene (Hsp70-1) Sequence In Aradi And Damascus Goat Breeds (Capra Hircus) Raised Under Heat Stress Conditions

Ten animals from two goat breeds (Aradi and Damascus) raised under heat stress conditions in Saudi Arabia were used in this study to compare the sequence of Heat Shock Proteins-70 gene (HSP70-1) between Aradi and Damascus goats with the reported one of Yunnan black goat (Capra hircus). From the sequence of the above mentioned three breeds Aradi, Damascus and Yunnan, it could be identify that, Damascus goats are more mutant to HSP70-1 gene sequence than other breeds. The results of study also showed an addition of A, T and G nucleotides in positions 935 (AGAAAGGCTC), 984 (GGTTCCTGGT) and 997 (GGGGGGGCTC) in Damascus Goats. However, Aradi goats did not differ in these positions from Yunnan black goats (AGAAAGGCTC, GGTTCCTGGT and GGGGGGGCTC). It could be concluded that HSP70-1 gene sequence varied between Aradi and Damascus breeds and Damascus breed showed more mutation in DNA sequence in 3 positions, Aradi breed did not show any variation in relation to that published for Capra hircus.
