Abstract

This paper describes the sequence of 257 nucleotides from the 3' end of RNA 2 of barley stripe mosaic virus ( BSMV , strain Argentina Mild) including an internal oligo (A) tract localized at a distance of 236 nucleotides from the 3' end, and the 3' terminal tRNA-like structure accepting tyrosine. This sequence is shown to be the same with RNAs 1,2 and 3 of another BSMV strain, Norwich , for at least the first 106 nucleotides from the 3' end. The 3' extremity of BSMV RNA bears some resemblance to tRNATyr from yeast in its primary structure. The possible secondary structures of the tRNA-like sequence in BSMV genome are discussed.

摘要

本文描述了大麦条纹花叶病毒(BSMV,阿根廷温和株系)RNA 2 3' 端的257个核苷酸序列,包括一个位于距3' 端236个核苷酸处的内部寡聚(A)序列,以及接受酪氨酸的3' 末端tRNA样结构。已证明该序列与另一个BSMV株系诺维奇的RNA 1、2和3至少在3' 端的前106个核苷酸上相同。BSMV RNA的3' 末端在一级结构上与酵母的tRNATyr有一些相似之处。文中还讨论了BSMV基因组中tRNA样序列可能的二级结构。
