“…TNV-like viruses, that were able to be assigned to TNV-D or TNV-A, have been detected in herbaceous plants such as tobacco, tulip, bean, cucumber and potato, as well as woody crop plants such as pear and apple, citrus, grape (Kassanis, 1970;Kurstak, 1981) and olive (Félix and Clara, 2002b). OMMV was identified for the first time in olive and genomic sequences of OMMV, published in the Genbank database, were recovered from tulips affected by the Augusta disease, leading to its identification as the causal agent of that disorder (Pham et al, 2009 Mixed infections of these three viruses occur naturally quite frequently (Félix and Clara, 2002a;Varanda et al, 2010). These alphaand betanecroviruses share important similarities.…”
