Abstract

A circular, viroid-like satellite RNA (sat RNA) was detected in lucerne transient streak virus (LTSV), from lucerne in South Australia. It was larger than the previously reported sat RNA of LTSV, being similar in size and sequence homology to the 388 nucleotide sat RNA previously shown to be encapsidated by subterranean clover mottle virus (SCMoV) isolated from subterranean clover in Western Australia. This indicates that under field conditions, very similar sat RNAs can be associated with two distantly related sobemoviruses, LTSV and SCMoV. The natural hosts of these viruses are lucerne and subterranean clover, respectively.

摘要

在来自南澳大利亚紫花苜蓿的紫花苜蓿瞬态条纹病毒（LTSV）中检测到一种环状、类病毒卫星RNA（sat RNA）。它比先前报道的LTSV的sat RNA更大，在大小和序列同源性上与先前显示被从西澳大利亚地下三叶草中分离出的地下三叶草斑驳病毒（SCMoV）包裹的388个核苷酸的sat RNA相似。这表明在田间条件下，非常相似的sat RNA可以与两种远缘相关的南方菜豆花叶病毒LTSV和SCMoV相关联。这些病毒的天然宿主分别是紫花苜蓿和地下三叶草。
