Description

Huijuan Xu and eight colleagues hunt chicken genes that slam the door on two leukosis viruses. Avian leukosis viruses cause tumors and immune damage in poultry, with no vaccine available, so breeding resistance is a prime strategy. Entry of the A and K subgroups depends on a cell receptor built by the tva gene, and six resistant versions of that gene were known. The team screened Qingyuan partridge chickens for them in their 2026 study.

Five resistant versions turned up in the breed. In cell tests, one version, tvar2, blocked both viruses completely, while the other four sharply cut the K virus's success. Live bird infections matched the dish results. The resistant versions were widespread in the breed, with some flocks carrying them at high rates. The authors offer these gene versions as ready targets for breeding programs.
