Keragaman Gen Myxovirus (Mx) pada Itik di Kabupaten Indragiri Hulu Provinsi Riau
The Mx gene (Myxovirus) is a gene that functions to control the immunity of poultry against viral
diseases. This gene is a native antiviral and is able to respond to influenza virus infections such
as avian influenza. This study aims to identify the diversity of the Mx gene in ducks using the
PCR-RFLP (Polymerase Chain Reaction-Restriction Fragment Length Polymorphism) molecular
technique. The number of samples used were thirteen ducks from Indragiri Hulu Regency (Riau
Province). The restriction site of the Mx gene using the Rsa1 enzyme is in the base sequence
GTN|NAC. There are two alleles namely A and G, and three genotypes, AA, AG and GG. The
results showed that the Mx gene in ducks was monomorphic. The frequency of the resistant allele
(A) is 0%, while the frequency of the susceptible allele (G) is 100%.
