The sequence of the 32 N-terminal amino acids of the protein (VPg) which is covalently linked to the RNA of potato leafroll virus has been determined. The obtained VPg sequence mapped to position 400 to 431 of the PLRV ORF1 product, downstream of the putative protease domain and in front of the RNA-dependent RNA polymerase. Comparison with other viral sequences revealed significant similarities with the ORF1 products of beet western yellows virus, cucurbit aphid-borne yellows virus, and beet mild yellowing virus.
已确定与马铃薯卷叶病毒RNA共价连接的蛋白质（VPg）32个N端氨基酸的序列。所获得的VPg序列定位于PLRV ORF1产物的第400至431位，在假定的蛋白酶结构域下游且在RNA依赖性RNA聚合酶之前。与其他病毒序列的比较显示，与甜菜西方黄化病毒、葫芦蚜传黄化病毒和甜菜轻度黄化病毒的ORF1产物有显著相似性。
