Abstract excerpt
Two Citrus exocortis viroid isolates (CEVd-s and CEVd-129) that induce severe and mild symptoms in Gynura aurantiaca, respectively, have been characterized. They present nucleotide sequences in the pathogenicity motifs P(L), C and P(R) similar to those of "Class A" and "Class B". Infectivity and symptom expression in G. aurantica and tomato were evaluated with a selection of sequence variants recovered from both...
