摘　　要：[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 isolates.In 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.[目的]研究十四株网状内皮组织增生症病毒中国分离株gp90基因的分子特征。[方法]对分离于我国不同商品蛋鸡场的14株REV的表面囊膜基因gp90进行了扩增和序列测定。[结果]序列分析表明,这14株REV不同于我国早期分离毒株与亚型3毒株亲缘关系较近。另外发现,这14株REV与美国和我国台湾的流行毒株同源性较高。[结论]本研究对深入研究我国REV的流行和遗传演化意义重大。
