[Objective] The paper was to study molecular characteristics of gp90 gene of 14 Reticuloendotheliosis viruses isolated in China. [Method] The surface envelop gene gp90 of 14 REV strains isolated from different commercial layer farms in China were amplified, and their nucleotide sequences were determined. [Result] Sequence analysis showed 14 REV strains were more identical to the subtype 3 isolates than to the early Chinese REV isolates. In addition, 14 REV strains had a high identity with some REV strains in US and Taiwan. [Conclusion] The study provided necessary information for further understanding the evolution of REV.
