[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 showes that 14 REV strains are more identical to the subtype 3 isolates than to the early Chinese REV *** addition,14 REV strains have a high identity with some REV strains in US and Taiwan.[Conclusion] The study provided necessary information for further understanding the evolution of REV.
