The complete genome sequences of RNA1 and RNA2 of the oca strain of the potato virus arracacha virus B were determined using next-generation sequencing. The RNA1 molecule is predicted to encode a 259-kDa polyprotein with homology to proteins of the cheraviruses apple latent spherical virus (ALSV) and cherry rasp leaf virus (CRLV). The RNA2 molecule is predicted to encode a 102-kDa polyprotein which also has homology to the corresponding protein of ALSV and, to a lesser degree, CRLV (30 % for RNA1, 24 % for RNA2). Detailed analysis of the genome sequence confirms that AVB is a distinct member of the genus Cheravirus.
利用新一代测序技术，测定了马铃薯卷叶病毒 B 的 oca 株系的 RNA1 和 RNA2 的完整基因组序列。RNA1 分子预测编码一个 259kDa 的多蛋白，与苹果潜隐病毒 (ALSV) 和樱桃皱叶病毒 (CRLV) 的蛋白具有同源性。RNA2 分子预测编码一个 102kDa 的多蛋白，与 ALSV 的相应蛋白也具有同源性，与 CRLV 的同源性较小 (RNA1 为 30%，RNA2 为 24%)。对基因组序列的详细分析证实，AVB 是 Cheravirus 属的一个独特成员。
