Abstract
Background: The selection of Marek’s disease (MD)-resistant breeds in Partridge Shank chicken, a popular
local chicken breed in Henan Province of China, has practical value. We hypothesized that the two polymorphic sites
(
rs14527240 located in
SMOC1 and
GGaluGA156129 located in PTPN3) related to MD resistance in White Leghorn
chickens are also applicable to Partridge Shank chickens.
Methods: In this experiment, we screened 10 live hens and 2
live roosters with the double GG genotype by genotyping the two sites from 6500 Partridge Shank chickens. Nineteen
one-day-old chicks with the double GG genotype were obtained by artificial insemination. Seventy-two one-day-old
chickens (19 from the population expansion test and 53 randomly selected from chicken farms) were injected with
2000 plaque-forming units of the Md5 virus strain. After 100 days of infection, all chickens were examined by
pathological anatomical examination, histological sectioning, genotyping, and a quantitative polymerase chain reaction
of
SMOC1 and
PTPN3.
Results: There was only one site (
rs14527240 located in
SMOC1) associated with MD in
Partridge Shank chickens (
p < 0.05), but the GG genotype of
SMOC1 in Partridge Shank chickens indicated
susceptibility to MD.
SMOC1 expression in MD-susceptible chickens was also significantly higher than that in MDresistant chickens (
p < 0.05).
Conclusion: Therefore, the MD resistance sites selected from White Leghorn chickens
were not completely suitable for Partridge Shank chickens, but they can be used as a reference. This study indicated
that
SMOC1 plays an important role in screening for MD resistance in poultry.
