Fig. 6

Variation of deletion/mutation nucleotide numbers in the UPD region during 10 rounds of serial passaging of TMV (24A + UPD). The x-axis represents the number of serial passaging and the y-axis represents the deleted/mutated nucleotide numbers. The black dots in each round of serial passaging represent the clones with nucleotide deletion/mutation in the sequence downstream of internal poly(A) tract
