Abstract excerpt

Comparison of the nucleotide sequences of cucumber mosaic virus (CMV) satellite RNAs, which induce necrosis on tomatoes, reveals a highly conserved region within their 3' halves. The sequence of WL1 satellite (WL1-sat) RNA, which attenuates CMV symptoms on tomatoes, differs from all necrogenic sa...
