a The nucleotide positions of the short non-coding sequence and pseudoknots (PKs) in the UPD were labeled. The stop codon of coat protein (CP) gene was boxed and the nucleotide downstream of 24 nt internal poly(A) tract was counted as the first nucleotide. b Percentage of clones with deletion/mutation in sequence of the short non-coding sequence, UPD and TLS in TMV (24A + UPD) during serial passaging
