Abstract

The nucleotide sequence of a satellite RNA (satRNA) associated with a lilac isolate of arabis mosaic virus (ArMV) was determined from cDNA copies. The sequence was 1104 nucleotides in length excluding the poly(A) tail, contained a long open reading frame which encodes a polypeptide of 360 amino acids, with an Mr of 39K. Nucleotide sequence comparisons revealed that the ArMV-associated satRNA shared 83% nucleotide identity with a satRNA from grapevine fanleaf nepovirus, but no extensive sequence homology was observed with other nepoviral satRNAs.

摘要

通过互补DNA（cDNA）拷贝测定了与丁香花叶病毒（ArMV）丁香分离株相关的卫星RNA（satRNA）的核苷酸序列。该序列长度为1104个核苷酸，不包括聚腺苷酸（polyA）尾，包含一个长开放阅读框，编码一个由360个氨基酸组成的多肽，分子量为39K。核苷酸序列比较显示，与ArMV相关的satRNA与葡萄扇叶线虫传多面体病毒的一个satRNA具有83%的核苷酸同一性，但未观察到与其他线虫传多面体病毒satRNA有广泛的序列同源性。
