DNA sequencing of genomic cDNA clones of avian infectious bronchitis virus (IBV) has been carried out. 770 bases have been determined which include genomic sequences spanning the 5' termini of the two smallest mRNAs of the 3'-coterminal "nested" set: mRNA A and mRNA B. This region contains the complete coding sequences for mRNA B which are additional to those present in mRNA A. Two open reading frames are present, predicting proteins of Mrs 7500 and 9500.
已对禽传染性支气管炎病毒(IBV)的基因组cDNA克隆进行了DNA测序。已确定了770个碱基,其中包括跨越3'-共末端“嵌套”组中两个最小mRNA(mRNA A和mRNA B)5'末端的基因组序列。该区域包含mRNA B的完整编码序列,这些序列是mRNA A中所没有的。存在两个开放阅读框,预测的蛋白质分子量分别为7500和9500。
