Poly(A) introduced upstream of the upstream pseudoknot domain of Tobacco mosaic virus led to sequence deletion after serial passaging in host plants

Abstract TMV (24A + UPD) is a mutant virus that a 24 nt internal poly(A) tract was introduced downstream of the coat protein (CP) gene in TMV genome. TMV (24A + UPD) induced more severe necrosis in Nicotiana benthamiana and its RNA level accumulated at higher level than that of TMV, indicating that...
